Abstract

The present invention relates to agricultural marc, and food compositions incorporating such agricultural marc to improve the texture, flavor, aroma, mouthfeel, nutritional content, or shelf life of the food composition. In one example, the agricultural marc may be obtained from Chardonnay grapes, which when incorporated into chocolate can give the resulting composition an altered flavor and/or aromatic profile.

Description

FOOD COMPOSITIONS INCORPORATING AGRICULTURAL MARC, AND METHODS OF PRODUCING THEREOF CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to U.S. Provisional Patent Application No. 63/092,976 filed on October 16, 2020, the contents of which are incorporated herein by reference in their entirety. FIELD [0002] The present disclosure relates generally to food compositions, including chocolate compositions, and more specifically to food compositions that incorporate agricultural marc in a sustainable way that enhances the human sensory experience and improves nutrition in such compositions. BACKGROUND [0003] Agricultural processes impact the environment and contribute to global warming. One way to lessen the impact of agriculture on the environment is to maximize commercial use of agricultural byproducts. For instance, production of fruit results in large amounts of marc (also known in the art as pomace), which includes fruit skins, seeds and pulp. The marc has potential uses in food production. Valorization of different agricultural byproduct streams, such as agricultural marc, into food ingredients can increase the nutritional value and caloric content that can be derived per acre of crop production. However, these byproduct streams are often challenging to process and develop into ingredients that can be easily incorporated into food production systems or are attractive to consumers. [0004] What is desired in the art are foods that are generally healthier for the average consumer without sacrificing sensory experience. What is also desired are foods with reduced sugar and/or incorporation of fruit or vegetable products in a way that preserves consumer acceptance. Thus, creating nutritionally-enhanced foods with favorable consumer reception remains a challenge in the food industry. BRIEF SUMMARY [0005] In some aspects, provided is a food composition comprising chocolate and agricultural marc. In some embodiments, the agricultural marc is present in an amount of between 1% and 50% by weight of the total food composition. In some embodiments, the weight ratio of chocolate to marc is between 1:1 and 100:1. In some variations of the foregoing, the food composition comprises cocoa butter present in an amount between 0.5% and 40% by weight of the total food composition. In some variations of the foregoing, the food composition has fruity or total fruit aromatic attributes, grape aromatic attributes, blueberry attributes, pleasant mouthfeel attributes, and/or sweet taste attributes, or any combination thereof, each independently at a rating of 0.5 or higher on a scale of 0 to 4. In additional variations of the foregoing, the food composition has bitter taste attributes and/or grape aromatic attributes each independently at a rating of 2.5 or lower on a scale of 0 to 4. In some variations of the foregoing, the food composition has an aromatic attribute selected from the group consisting of fruit complex, brown fruit, raisin, red fruit, and cherry cordial, or any combination thereof, each independently at a rating of 0.5 or higher on a scale of 0 to 15 (e.g., as measured using the Spectrum Descriptive Analysis method). In yet additional variations of the foregoing, the food composition has astringency flavor notes of 3.0 or lower, or has bitter flavor notes of 2.5 or lower, or a combination thereof, on a scale of 0 to 15 (e.g., as measured using the Spectrum Descriptive Analysis method). In still additional variations of the foregoing, the food composition has sweet flavor notes at a rating of between 6.0 and 10.0 on a scale of 0 to 15 (e.g., as measured using the Spectrum Descriptive Analysis method). In some variations, the food composition has a sugar content of less than 25% by weight, a fiber content above 10% by weight, or a combination thereof.

DETAILED DESCRIPTION [0016] The following description sets forth exemplary compositions, methods, parameters and the like. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments. [0017] In some aspects, provided are food compositions that incorporate agricultural marc. In some embodiments, the food compositions are chocolate compositions. For example, in certain aspects, provided is a chocolate composition that incorporates agricultural marc. [0018] Incorporation of agricultural marc into food compositions, including chocolate, can enhance the human sensory experience and improve nutrition of such food compositions. In some variations, incorporating agricultural marc into chocolate formulations may reduce bitterness, reduce astringency, alter textural and visual appeal, improve mouthfeel, and/or enhance flavor and aroma profile. In certain variations, such incorporation may lead to functional improvements in the resulting chocolate composition. For example, incorporating agricultural marc derived from fruits or vegetables into chocolate formulations can improve shelf life, reduce costs of inputs, alter the ratios of other ingredients, increase fiber content, increase dietary phenol content, decrease sugar content, and/or decrease total caloric content. [0019] The following describes the agricultural marc, the food compositions, and the methods of producing such food compositions in further detail. Agricultural Marc [0020] In some embodiments, agricultural marc comprises byproduct resulting from the harvesting and processing of fruits or vegetables. Marc is also known in the art as pomace.

[0026] The average particle size of the agricultural marc in the food composition can be reduced using any suitable methods or techniques known in the art. For example, grinding or milling may be employed to reduce the particle size of agricultural marc to the desired range prior to incorporation into the food composition. In some embodiments, the agricultural marc is dry-milled prior to incorporation into the food composition. The average particle size of the agricultural marc in the food composition can be measured using any suitable methods or techniques known in the art including, but not limited to, by micrometer or laser diffraction. [0027] In some variations, the reduced particle size of the agricultural marc incorporated into the food composition can improve consumer experience and/or utility, for example, by improving product stability and replacing stabilizers; increasing soluble fiber content and bioavailability; increasing dietary phenol content and bioavailability; improving aromatic and flavor profiles in the food composition; lowering the cost of agricultural marc utilization; increasing nutritional benefit; improving production efficiency; and/or altering formulations of ingredients to reduce overall production costs. [0028] In some embodiments, the agricultural marc powder has a soluble fiber content of at least 5% of the weight of the pure marc powder. In some variations, the agricultural marc powder has a soluble fiber content of at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, or at least 70% by weight. In other variations, the agricultural marc powder has a soluble fiber content between 5% and 10%, between 10% and 20%, between 20% and 30%, between 30% and 40%, between 40% and 50%, between 50% and 60%, or between 60% and 70% by weight. [0029] In some embodiments, the agricultural marc comprises an amount of phenols and/or polyphenols, which may include, but are not limited to, flavonoids (e.g., flavanols, also known as flavan-3-ols), phenolic acids, stilbenes, and the like. In some embodiments, the agricultural marc powder has a total phenolic content of at least 0.1 mg GAE/g. Gallic acid equivalents (GAE) is a standard means of expressing total phenolic content in a sample. GAE can be determined by the Folin Ciocalteau method (Taga, M.S.; Miller, E.E.; Pratt, D.E. Chia seeds as a source of natural lipid antioxidants. Journal of American Oil Chemistry Society 1984, 61, 928–931), or using any suitable means known in the art. In some variations, the agricultural marc powder may have a total phenolic content of at least 0.5mg GAE/g, at least 1mg GAE/g, at least 5mg GAE/g, at least 10 mg GAE/g, at least 20 mg GAE/g, at least 30 mg GAE/g, at least 40 mg GAE/g, at least 50 mg GAE/g, at least 60 mg GAE/g, at least 70 mg GAE/g, at least 80 mg GAE/g, or at least 90 mg GAE/g.

[0033] In certain embodiments, the agricultural marc is derived from seeds. For example, in one variation to obtain agricultural marc from seeds, the seeds may first be separated from skins, stems, and/or leaves. The seeds are then pressed to separate seed oil (e.g., by cold press, hot press, or solvent extraction methods), leaving behind a de-fatted seed material after oil pressing (e.g., a meal or flour). The meal or flour can be dried, and then processed using any of the particle size reduction techniques described herein to yield the agricultural marc in powder form. In one variation, agricultural marc is derived from grape seeds that have been dried and pressed to release the seed oil. In another variation, agricultural marc is derived from milling of fruit or vegetable seeds. In other variations, agricultural marc is derived from olives. In another variation, olives may be milled and malaxed to extract the oil, and the resulting agricultural marc byproduct is utilized in the food compositions. Grape Marc [0034] In some embodiments, grape marc is used in the food compositions described herein. The grape plant from which grape marc is obtained may be any species of the genus Vitis. For example, grape marc may be derived from Vitis vinifera, Vitis amurensis, Vitis labrusca, Vitis mustangensis, Vitis riparia, or Vitis rotundifolia. The grape marc may be obtained from any suitable grape variety, including for example, Chardonnay, Concord, Pinot Noir, Pinot Grigio, Sauvignon Blanc, Cabernet Sauvignon, Zinfandel, Merlot, Malbec, Thompson, Mauzac, Grenache, Grenache Blanc, Syrah, Riesling, Viognier, or any combination thereof. [0035] In some embodiments, the agricultural marc comprises or consists essentially of marc from a fruit of a plant of the clade Rosids. In some embodiments, the agricultural marc comprises or consists essentially of grape marc. In certain embodiments, the agricultural marc comprises or consists essentially of marc from a fruit of a plant in the order Vitales. In certain embodiments, the agricultural marc comprises or consists essentially of marc from a fruit of a plant in the family Vitaceae. In certain embodiments, the agricultural marc comprises or consists essentially of marc from a fruit of a plant in the genus Vitis. In certain embodiments, the agricultural marc comprises or consists essentially of Chardonnay marc. In certain embodiments, the agricultural marc comprises or consists essentially of Concord grape marc. In some embodiments, the agricultural marc comprises a mixture of two or more grape marcs described herein. [0036] In some embodiments, the grape from which marc is obtained is a grape grown in a coastal region. In some embodiments, the grape is a grape grown in a Winkler region climate type I, II, III, IV or V. In some variations, the agricultural marc is obtained from grapes grown in the coastal valleys of Northern California, e.g., the Napa Valley and/or the Sonoma Valley. In another variation, the grape marc is obtained from grapes grown in other, hotter, inland valley vineyards, including any other suitable environments, states and/or countries. [0037] In some embodiments, the food compositions incorporate Chardonnay marc, Concord grape marc, Pinot Noir marc, Pinot Grigio marc, Sauvignon Blanc marc, Cabernet Sauvignon marc, Zinfandel marc, Merlot marc, Malbec marc, Thompson marc, Mauzac marc, Grenache marc, Grenache Blanc marc, Syrah marc, Riesling marc, Viognier marc, or any combination thereof. In some embodiments, the grape marc comprises Chardonnay marc, Concord grape marc, or a combination thereof. In one variation, the grape marc is Chardonnay marc. In another variation, the grape marc is Concord grape marc. [0038] In some embodiments, grape marc may be derived from a juice production process. For example, in some variations grapes are crushed to produce juice, and the remaining stems, leaves, skins, pulp, and/or seeds are utilized for grape marc. In other embodiments, grape marc is derived from a wine fermentation process. For example, in other variations, grape marc is derived from crushed whole grapes, including stems, leaves, skins, pulp, and/or seeds, which have undergone a fermentation process. In yet another variation, grape marc is derived from yeast lees, including, for example, the residue of pressed grapes, small pieces of stalks, yeast cells, and other byproducts from the wine fermentation process. Grape marc derived from a wine-making process may also be known in the art as wine marc or wine pomace. [0039] Grape marc may generally be obtained using any suitable processes known in the art. For example, grape marc may be obtained from a juice production process. The grape marc may be passed through a crusher/destemmer to remove stems and leaves. Any stones and/or metal present in the marc may also be removed using any suitable techniques known in the art. The marc may be rinsed with water, following by pressing to remove at least a portion of the water. The marc may be further dried using any suitable means known in the art including, for example, conducive heat or hot air drying. Any particle size reduction technique known in the art or described herein may then be employed to produce a marc powder from the dried marc. [0040] In other embodiments, grape marc is made by separating and drying grape seeds, for example, from the materials produced after grapes are pressed to produce grape juice (e.g., to make wine). The grape seeds can be "cold-pressed" to defat them (producing seed oil as a byproduct). After the oil is expelled, the press cake can be milled to produce an agricultural marc in powder form. In one embodiment, after juicing, the grape seed is separated from the skins, cleaned, dried, mechanically defatted, finely milled and sifted to create a marc with the average particle sizes described herein. [0041] In yet other embodiments, the grape marc is obtained from a defatted portion of the grape seed. In some variations, the grape marc comprises defatted grape seeds that are not extractable by an organic solvent, e.g., are not extractable by ethanol and/or methanol. In certain aspects, the grape marc is prepared from seeds having an epicatechin content of at least 600 mg of epicatechin per 100 g of seeds or an epicatechin content of at least 700 mg of epicatechin per 100 g of seeds. In specific embodiments, the epicatechin content ranges from 600-800 mg/100 g of seeds or from 650-800 mg/100 g of seeds.

An exemplary method for evaluating aromatics and flavors on the SDA scale is described in Example 4. [0082] In some variations of the foregoing, aromatics and flavors are rated on a scale of 0 to 4 using a sensory evaluation method. For example, in one such method, a group of six panelists of varying ages and genders with 10-20+ years’ professional experience in the food or dietary supplement industry are used to determine the sensory attributes of food products (e.g., chocolates) employing a modified quantitative descriptive analysis. At least twelve flavor attributes from three flavor categories may be evaluated including: 1) retronasal aroma (seven attributes; in-mouth), 2) basic taste (four tastes; bitter, sweet, salty, sour); 3) mouthfeel – astringency (pleasant mouthfeel). Exemplary flavor attributes which may be evaluated are shown in Tables 1A-1C. The panelists are asked to taste each food product (e.g., chocolate) and asked to score each flavor attribute on a nine-point scale from 0 to 4, in which 0 = not observable, 1 = weak intensity, 2 = moderate intensity, 3 = strong intensity, and 4 = extreme intensity (in 0.5 increments). First, the control food product (e.g., chocolate) is evaluated and scored for all twelve flavor attributes. Then, each test food product (e.g., chocolate) is evaluated, and the panelists are asked to score the test food product’s flavor attributes in relation to the intensity of the same flavor attribute in the control food product(s). For palate cleansing, breaks are taken in between each flavor evaluation. Table 1A. Seven exemplary aroma attributes (Retronasal- in-mouth).

Methods to Manufacture the Food Compositions [0099] In other aspects, provided are methods for preparing the food compositions described herein that incorporate agricultural marc. In some embodiments, the method comprises combining an agricultural marc with a base composition. In some variations, the agricultural marc may be mixed into a base food composition. In other variations, the agricultural marc may be combined with one or more ingredients of the base food composition. [0100] For example, in the context of chocolate production, in one variation, agricultural marc may be incorporated to a chocolate base composition that already comprises one or more of unsweetened chocolate, sugar, cocoa butter, and other ingredients mixed together. In such variation, the chocolate base composition serves as a base starting material for the chocolate production process. In certain variations, the chocolate base composition comprises a composition derived from cacao beans, with or without cocoa butter. In certain variations, the chocolate base composition may be a powder, a liquid, an oil, a fat, or an emulsion. In some embodiments, the chocolate base composition may include one or more of cocoa powder, cocoa butter, melted chocolate, chocolate liquor, melted semi-sweet chocolate, melted dark chocolate, or melted high-flavanol chocolate. [0101] In another variation, agricultural marc may be combined with one or more of cocoa powder, cocoa butter, melted chocolate, chocolate liquor, melted semi-sweet chocolate, melted dark chocolate, or melted high-flavanol chocolate, as well as any of the additional ingredients described herein (e.g., sugar, flavorings, etc.) [0102] In certain embodiments, agricultural marc is incorporated into a chocolate base composition in the form of a powder, including having any of particle sizes and other properties described herein. In certain embodiments, the agricultural marc powder is homogenously incorporated. In some variations, the agricultural marc powder may be incorporated into the chocolate base composition in a dry or wet format. In some variations, the chocolate base composition may be further homogenized after the addition of agricultural marc powder. For example, the chocolate base composition incorporating the agricultural marc powder may be passed through a roller refiner. In some variations, the chocolate composition may be tempered and formed into bars. In other variations, the chocolate composition may be shaped or formed into a variety of conformations and shapes. EXAMPLES [0103] The presently disclosed subject matter will be better understood by reference to the following Examples, which are provided as exemplary of the invention, and not by way of limitation. Example 1: Processing of Chardonnay marc [0104] This Example depicts an exemplary method used to process Chardonnay grapes into a marc ingredient suitable for incorporation into chocolate. [0105] Chardonnay marc was produced in a juice production process. The marc was cleaned by removing residual stems, leaves, stones, and metal. The marc was then rinsed with clean water and then pressed to remove most of the water. The resulting marc was dried and then dry- milled to achieve an average particle size of around 100 microns. The resulting Chardonnay marc powder was incorporated into the food compositions described in Examples 2 and 3. Example 2: Batch production and characterization of chocolate bars containing Chardonnay marc [0106] The Chardonnay marc produced in Example 1 was used to prepare several batches of chocolate with Chardonnay marc. These batches were analyzed for their flavor, mouthfeel, and nutritional content. Semi-Sweet Chocolates Containing Chardonnay Marc [0107] Several semi-sweet chocolate bars containing varying amounts of Chardonnay marc were produced. Initial efforts were focused in on the usage rate of the marc in chocolate. Three different usage rates were chosen for the initial testing: 8%, 15%, and 25%. First, semi-sweet chocolate was melted in a microwave and mixed with a roughly equal amount of Chardonnay marc, which was incorporated into the melted chocolate to create a paste. This paste was refined using a roller refiner. In the first pass, it was passed through at 400-450 psi, resulting in a mixture with an average particle size of 25-35 microns. In the second pass, it was subjected to 450-475 psi, resulting in a mixture with an average particle size of 15-17 microns. Melted cocoa butter and lecithin were then added to the refined chocolate and marc mixture, and the mixture was mixed on a mixer with a heated mantle until fully homogenous to create a base chocolate- marc mixture. Table 2 outlines the ingredient makeup of this base chocolate-marc mixture. Table 2. Ingredient makeup of the base chocolate-marc mixture. Ingredient % Amount (g) Semi-Sweet C_hocolate ^{45% 1020.4} Marc 50% 1135.0 Cocoa Butter 5% 113.5 Lecithin <1% 1.1 Total 100% 2270.0 [0108] This high of concentration of marc was not appropriate as an eating chocolate without dilution. Therefore, the base chocolate-marc mixture was then used to create semi-sweet chocolate bars containing 8%, 15%, and 25% Chardonnay marc, with or without the addition of vanilla. First, the chocolate-marc mixture was melted down and mixed in the appropriate ratio with semi-sweet chocolate, and vanilla was added as appropriate. This mixture was then tempered and molded into bars. The bars were analyzed for nutritional content and tasted for mouthfeel and flavor. Table 3 shows the ingredient makeup of the resulting chocolate bars.

*One serving is 28 grams. Dark Chocolates Containing Chardonnay Marc [0109] Dark chocolate bars containing 25% Chardonnay marc were produced. First, dark chocolate was melted in a microwave and mixed with Chardonnay marc at a roughly 3:1 ratio of chocolate to marc. The marc was fully incorporated into the melted chocolate to create a paste. This paste was refined using a roller refiner. In the first pass, it was passed through at 400-450 psi, resulting in a mixture with an average particle size of 25-35 microns. In the second pass, it was subjected to 450-475 psi, resulting in a mixture with an average particle size of 15-17 microns. Melted cocoa butter and lecithin were then added to the refined chocolate and marc mixture, and the mixture was mixed on a mixer with a heated mantle until fully homogenous. The chocolate was then transfer a melted where it stayed for 24 hours at 100-115 °F. The chocolate was then tempered and molded into bars. Table 4 shows the ingredient makeup of the resulting chocolate bars. The dark chocolate bars with marc were observed to have the good sweetness, a slightly gummy mouth feel with some tart and tannin notes, but fewer tart notes than the semi-sweet chocolates. Table 4. Ingredient makeup of 25% Chardonnay marc dark chocolate.

Chocolates Containing Chardonnay Marc Made from Chocolate Liquor [0110] Chocolate bars containing 25% Chardonnay marc were produced from scratch using chocolate liquor. First, chocolate liquor was melted in a microwave and mixed with Chardonnay marc at a roughly 3:1 ratio of chocolate to marc. The marc was fully incorporated into the melted chocolate to create a paste. This paste was refined using a roller refiner as described above. The particle size of the scratch chocolate mixture with marc was measured by micrometer after 1:1 dilution of the chocolate in mineral oil. Melted cocoa butter, sugar, and lecithin were then added to the refined chocolate and marc mixture, and the mixture was mixed on a mixer with a heated mantle until fully homogenous. One batch of the chocolate was run through a conche for 48 hours at 105-115 °F (“Conched Chocolate”) while another was not (“Scratch Chocolate”). The chocolate was then tempered and molded into bars. [0111] Table 5 shows the ingredient makeup and particle sizes of the Scratch and Conched Chocolate bars. The Scratch Chocolate bars were observed to have improved flavor and texture over the semi-sweet and dark chocolates with marc, including good sweetness, a less gummy mouth feel and fewer harsh acidic notes. The Scratch Chocolate did retain some grittiness. The Conched Chocolate was further improved over the Scratch Chocolate, with less grit, more round flavor, and no harsh notes, though it retained some gumminess. Table 5. Ingredient makeup of 25% Chardonnay marc Scratch and Conched Chocolates.

*One serving is 28 grams. Reduced Sugar Chocolate Containing Chardonnay Marc [0112] Reduced sugar chocolate bars containing 25% Chardonnay marc were produced using chocolate liquor and allulose using the same method as described above in “Chocolates Containing Chardonnay Marc Made from Chocolate Liquor”, except the method was modified to use a 1:1 ratio of chocolate liquor to marc and sugar and allulose were added before the roller refining step. The reduced sugar chocolate was not run through a conche. Table 6 shows the ingredient makeup and particle size of the resulting reduced-sugar bars. The reduced sugar bars were found to have the same quality as the Scratch Chocolate bars, including good sweetness without the need for additional sweeteners. Table 6. Ingredient makeup of reduced sugar Chardonnay marc chocolate.

*One serving is 28 grams. High-Flavanol Chocolate Containing Chardonnay Marc [0113] High-flavanol chocolate bars containing Chardonnay marc were also produced. One batch (“Flavanol-Enhanced Chocolate”) was produced using the same method as described in “Chocolates Containing Chardonnay Marc Made from Chocolate Liquor”, except that a high- flavanol chocolate was used as a base instead of chocolate liquor, and no sugar or lecithin was added. Another batch was formulated to contain 250 mg flavanols per 28g serving (“250 mg Flavanol Chocolate”) using the same method as for Flavanol-Enhanced Chocolate, except that semi-sweet chocolate was melted and mixed into the marc-containing chocolate along with the cocoa butter and lecithin. Table 7 shows the ingredient makeup and particle size of the resulting flavanol-enhanced bars. Table 7. Ingredient makeup of flavanol-enhanced marc chocolates.

Chocolate with 20% Chardonnay Marc [0114] Semi-sweet chocolate bars with 20% Chardonnay marc was used to test mouth feel. The bars were produced using the method as described in “Dark Chocolate Containing Chardonnay Marc” except that semi-sweet chocolate was used as the base, high-flavanol chocolate was added after incorporation of the marc, and the chocolate was not allowed to sit in a melter before tempering and molding. Table 8 shows the ingredient makeup of the resulting 20% Chardonnay marc semi-sweet bars. Table 8. Ingredient makeup of 20% Chardonnay marc semi-sweet chocolate bars.

*One serving is 28 grams. Example 3: Production of Prototype Chocolates Containing 15% Chardonnay Marc [0115] Four prototype batches of chocolate containing 15% Chardonnay marc were produced. Table 9 shows their ingredient makeup. Table 9. Ingredient formulas for prototype chocolates containing 15% Chardonnay marc.

*One serving is 30 grams. Example 4: Sensory Features of Chocolate Containing 15% Chardonnay Marc [0116] The Batch 1 and Batch 4 prototype chocolate bars produced in Example 3 were each tested in a sensory panel to evaluate their sensory characteristics. Flavor and texture characteristics of each sample were documented to understand similarities and differences of the test products compared to the control space of available market products. Spectrum Descriptive Analysis Method [0117] The chocolates were evaluated using Spectrum Descriptive Analysis (SDA). In SDA, detailed lexicons with physical and chemical descriptors are used to discriminate among samples and document each sample with its unique flavor and texture Spectrum. SDA uses standard rating scales for intensity that provides highly reproducible data over time and panelists. Attribute Spectrums are developed for each product. The strength of each attribute is rated on a 0 – 15 scale with 0 = none and 15 = very strong. This scale incorporates the ability to use tenths of a point and therefore has the potential of 151 scale differentiations. Tables 10A and 10B define the flavor and texture attributes used in SDA. Table 10A. Description of flavor attributes used in SDA.

Table 10B. Descriptions of texture attributes used in SDA.

[0118] The samples were analyzed for flavor and texture by members of the Sensory Spectrum Food Panel, trained and experienced in each type of evaluation, using the SDA method described above. Prior to the first evaluation, the panel was oriented to the project and reviewed attribute references. The panelists evaluated each sample using the following procedure. Each panelist received 9 pieces (approximately 1 square inch) of chocolate to evaluate for flavor, and texture. Panelists recorded individual ratings, then each attribute was discussed until a consensus value was decided upon and recorded. All samples were expectorated. Additional samples were provided to the panelists, if needed. This process was repeated for each sample. Batch 1 Prototype Chocolate Sensory Panel [0119] Tables 11A-C show the results of the sensory panel evaluating the Batch 1 prototypes produced in Example 3. The highlights of these results are shown in FIG.1. Briefly, the prototype was noticeably different from the controls in terms of flavor, most notably in chocolate impact and fruity aromatics. The prototype and the Control 4 exhibited a lower chocolate essence which resulted in lower overall chocolate impression than the Controls 1-3. The prototype and Control 4 also have cocoa aromatic, dairy complex, vanillin, and nutty aromatics. The prototype had a raisin aromatic, characterized as white raisin, which was not present in the other samples. Surprisingly, the prototype exhibited a red fruit aromatic. The red fruit note in the prototype was characterized as cherry cordial, whereas Control 4 had a non-specific red fruit note. The nutty note in the prototype was characterized as old peanut, while the nutty note in Control 4 was characterized as general nutty. The dairy complex note in the prototype was characterized as nonfat dry milk, while the dairy complex note in Control 4 was characterized as cooked milk. There was no red fruit perceived in Controls 1-3. The prototype also lacked the dark roast aromatic but exhibited a nonfat dry milk aromatic not perceived in the controls. The prototype also exhibited a higher sour basic taste and a marginally higher salty flavor than the controls. Compared to Controls 1-3, both the prototype and Control 4 tasted less bitter. The decreased bitterness in the prototype was surprising in view of the use of Chardonnay marc. In terms of texture, the prototype was similar to Control 4 but distinct from Controls 1-3 in first chew attributes and rate of melt. A residual chalky mouthcoat was perceived with the prototype. Compared to Controls 1-3, both the prototype and Control 4 were softer, had lower snap, and were less fracturable on first chew. In chewdown, the mass of the prototype and Control 4 lacked coarse and had a higher rate of melt. Table 11A. Aromatic flavor characteristics of chocolate with and without Chardonnay marc.

*Evaluated after 3-4 chews. Intensities in bold indicate where both Control 4 and the prototype are outside the control space of Controls 1-3. Batch 4 Prototype Chocolate Sensory Panel [0120] Tables 12A-C show the results of the sensory panel evaluating the Batch 4 prototype produced in Example 3. Briefly, the prototype was noticeably different from the controls in some aromatic flavor attributes and residual mouthfeel attributes, while remaining in the control space for most aromatic and all basic taste and texture attributes. The Batch 4 exhibited a lower chocolate essence which resulted in lower overall chocolate impression than the control chocolates. Batch 4 also lacked a dark roast aromatic and had a slight nonfat dry milk aromatic that was not present in the controls. The vanilla complex of Batch 4 was distinct from the control, having a vanilla character with a slight vanilla presence, while the control chocolates had a stronger vanilla character and lacked vanillin. The fruit complex of Batch 4 was characterized as red fruity with supporting brown fruit, in contrast to controls 5 and 7, which were all brown fruit. The woody note in Batch 4 was further characterized as brown spice, in contrast to that of control 5, which was characterized as precious wood. The hardness with incisors, snap, and fracturable attributes of Batch 4 on first chew were well within the control space, as were the coarse and rate of melt chewdown attributes. A chalky residual mouthfeel was also perceived in Batch 4. Notably, the Batch 4 prototype was within the control space in terms of all basic tastes and astringency, and was the lowest-rated chocolate in terms of bitter taste (Table 12B). This is surprising, considering that Chardonnay marc is high in phenols that would be expected to add a bitter and/or astringent flavor. Further, the Batch 4 prototype was within the control space in terms of texture (Table 12C), despite the addition of Chardonnay marc which is high in fiber and would be expected to impact the texture of the chocolate. Table 12A. Aromatic flavor characteristics of chocolate with and without Chardonnay marc.

Example 5: Flavonoid content of Charonnday marc and chocolates comprising Chardonnay marc Flavonoid Analysis of Chardonnay Marc [0121] The Chardonnay marc prepared in Example 1 was analyzed for the presence and quantity of flavonoid compounds. Methodology [0122] To extract the phenolic compounds, Chardonnay marc was sonicated in 50% methanol:water in a 1:50 ratio by weight for 1 h at room temperature in a Lyman Turbo Sonic 6000 at 35 kHz. The supernatant was filtered through a 0.45 ^m Fisher Brand Nylon membrane prior to the ultra-performance liquid chromatography (UPLC) injection (5 ^L). The phenolic compound separation and quantification was conducted on an Agilent Zorbax Eclipse Plus C18 Rapid Resolution HD (3 × 100 mm, 1.8 ^m) installed on an Agilent 1290 UPLC coupled with a diode array detector (DAD). This method was modified from Ji, Li, and Li (2015. “Rapid separation and identification of phenolics in crude red grape skin extracts by high performance liquid chromatography coupled to diode array detection and tandem mass spectrometry.” Journal of Chromatography A, 1414, 138–146.). The mobile phase consisted of solvent A (0.2% formic acid in nanopure water) and solvent B (50% ACN:MeOH), with the gradient 95% to 65% A at 0–30 min; 65% to 60% A at 30–40 min; and 60% to 95% at A 40–42 min and flow rate was set to 0.5 mL/min. Each individual phenolic concentration was determined by peak area at 280 nm and individual calibration curves. Results [0123] Tables 13A-13C show the concentrations select flavonoid and phenolic compounds detected in the Chardonnay marc. A large body of scientific literature documents physiological effects and associated health benefits in humans and animals regarding dietary consumption of foods, beverages, and dietary supplements containing these compounds. It is also known that these compounds are generally bitter and astringent, thus presenting challenges for their incorporation into products with favorable sensory performance. Thus, Chardonnay marc represents a unique opportunity to deliver these compounds to food products via a material that contributes to highly desirable sensory performance and consumer compliance, rather than detracting from the sensory performance of the food product (see Examples 4, 7, and 8). Table 13A. Chardonnay marc flavan-3-ol concentrations.

Flavonoid Analysis of Chocolate Comprising 15% Chardonnay marc [0124] The chocolate Batch 4 prepared in Example 3 was analyzed for the presence and quantity of flavonoid compounds. Methodology [0125] 1. Fat removal. To remove excessive fat in the chocolate sample, 5 g of ground chocolate was weighed and dissolved in 45 mL hexane. The combined mixture was vortexed for 1 min, sonicated at 50 °C for 5 min, and centrifuged at 1700 rcf. The supernatant was decanted and the fat removal process was repeated two more times for a total of three hexane extractions. The solid chocolate portion was air-dried in a fumehood overnight to evaporate residual hexane. [0126] 2. Catechin and Epicatechin Enantiomers [0127] 2.1 Sample Extraction. Catechin and epicatechin enantiomers were characterized according to the AOAC Official Method 2013.04 (Machonis et al.2014. “Method for the determination of catechin and epicatechin enantiomers in cocoa-based ingredients and products by high-performance liquid chromatography: first action 2013.04.” Journal of AOAC International, 97(2), 506-509). Briefly, 50 mg of defatted chocolate was weighed and dissolved in 5 mL methanol:water:acetic acid (MWAA, 700:295:5, by vol.). The mixture was vortexed for 1 min and sonicated at 50 °C for 5 min for extraction. After centrifugation at 1700 rcf for 5 min, the supernatant was filtered through a 0.45 μm PTFE filter into a 2 mL amber vial for LC- FLD injection. [0128] 2.2 HPLC-FLD Determination. An Astec Cyclobond I-2000 RSP chiral column (250 × 4.6 mm x 5 ^m) was used for separation. The isocratic mobile phase was 20 mM ammonium acetate buffer (pH 4.0):methanol (7:3, by vol.) with a flow rate of 1 min/mL. The sample injection volume was 10 μL. The column temperature was set at 35 °C. The FLD was set with an excitation wavelength of 276 nm and an emission wavelength of 316 nm. The quantification was performed against calibration curves of (+)-catechin, (-)-catechin, (+)-epicatechin (not detected) and (-)-epicatechin, respectively. Analysis was conducted in duplicate. [0129] 3. Flavanols and Procyanidins DP1^7 [0130] 3.1 Extraction. Flavanols and procyanidins DP1^7 were characterized

following the newly published AOAC Official Method^SM 2020.05 (Bussy et al.2020. “Single- Laboratory Validation for the Determination of Cocoa Flavanols and Procyanidins (by Degree of Polymerization DP1–7) in Cocoa-Based Products by Hydrophilic Interaction Chromatography Coupled with Fluorescence Detection: First Action 2020.05.” Journal of AOAC International). Briefly, 200 mg of defatted chocolate sample was weighed and dissolved in 5 mL acetone:water:acetic acid (AWAA, 70:30:1, by vol.). The mixture was vortexed for 1 min and sonicated at 50 °C for 5 min. After centrifugation at 1700 rcf for 5 min, the supernatant was further cleaned up on a SPE MCX PRiME cartridge to eliminate the accumulation of matrix components on column which might lead to poor analytical performance. The SPE cartridge was conditioned using 2 mL AWAA and followed by 2.5 mL of extract. A total of 12 mL AWAA was then added to elute the extract into a 15 mL Falcon tube. Eventually, the AWAA- extract mixture was transferred into a 25 mL volumetric flask and further diluted with AWAA to a total of 25 mL solution. An aliquot was transferred to a 2 mL amber vial for LC-FLD injection. [0131] 3.2 HPLC-FLD Determination. A Waters Torus diol column (100 x 3.0 mm x 1.7 μm, 130A° particle size) was used for separation. The mobile phase is a binary gradient consisting of (A) acetonitrile:acetic acid (98:2, by vol.) and (B) methanol:water:acetic acid (95:3:2, by vol.) with a flow rate of 1 min/mL. The sample injection volume was 2 μL. The column temperature was held at 50 °C. The mobile phase gradient followed 0% B for 0.37 min and ramped to 45% B at 10.4 min and to 95% B at 10.65 min. Then 95% B was held for 2.35 min prior to returning to starting conditions (0% B) in 0.1 min. The total run time was 13.1 min. The FLD was set with an excitation wavelength of 230 nm and an emission wavelength of 321 nm. The quantification was performed against calibration curves of a cocoa extract reference material (NIST RM#8403) at each DP concentration. Analysis was conducted in duplicate. Results [0132] Tables 14A-14B show the concentrations of flavonoids detected in the chocolate comprising 15% Chardonnay marc. The total concentration of flavanols and procyanidins (DP1- 7) per serving was found to be 262.59 ± 3.72 mg/30g serving with fat (fat content of 42%). As discussed above, a large body of scientific literature documents physiological effects and associated health benefits in humans and animals regarding dietary consumption of foods, beverages, and dietary supplements containing these compounds. It is also known that these compounds are generally bitter and astringent, thus presenting challenges for their incorporation into products with favorable sensory performance. Thus, the chocolate comprising 15% Chardonnay marc represents a unique opportunity to deliver these compounds via food products having highly desirable sensory performance and consumer compliance attributes, as evidenced by the Batch 4 sensory attributes described in Example 4. Table 14A. Flavan-3-ol concentrations in chocolate comprising 15% Chardonnay marc.

Example 6: Particle size distribution of Charonnday marc and chocolates comprising Chardonnay marc [0133] A fine-milled marc powder was produced by dry-milling Chardonnay marc. Samples of the fine-milled marc and the Chardonnay marc described in Example 1 (before milling) were analyzed via laser light diffraction using a Beckman-Coulter LS 13320 to determine their particle size distribution. The particle size distributions of the marc samples are shown in FIG. 2A. [0134] Next, the particle size distribution of the Batch 4 chocolate produced in Example 3, as well as a control dark chocolate and a control milk chocolate, were analyzed via laser light diffraction using a Beckman-Coulter LS 13320. FIG.2B depicts the particle size distribution of the chocolates, as well as the fine-milled marc sample for reference. The particle size of each chocolate was also measured by mixing a sample with soybean oil and measuring via micrometer. Table 15 shows the average particle size of the chocolates as measured by micrometer. Table 15. Average particle size of chocolates with and without Chardonnay marc as measured by micrometer.

Example 7: Sensory characterization of increasing levels of Chardonnay marc in dark chocolate high in cocoa flavanols Preparation of Chocolates with Various Concentrations of Chardonnay Marc [0135] Eight batches of chocolate containing a range of Chardonnay marc concentrations were produced. High-cocoa flavanol (high-CF) base chocolates were batched in a temperature controlled bowl held at 60°C. The ingredients were melted in a 55°C convection oven and analyzed by micrometer for particle size. Table 16A shows the percentage and particle size of the ingredients used in the base chocolate. Cocoa butter was added visually to achieve a fluid paste. The batches were refined twice on a Lehmann 3 roll refiner to achieve target sizes of nominally 30-35 μm by micrometer. Refiner flake was placed into 55°C convection oven until re-melted. The entire batch of samples were remixed by spatula and sampled for micrometer particle size. Prior to the addition of Chardonnay marc, the high-CF base chocolate contained 301 mg cocoa flavanols per 30g serving (with fat). The fine-milled 2 Chardonnay marc powder produced in Example 6 was weighed according to the recipes in Table 16B. The weighed marc powder was added and the samples were conched for one hour at 55°C in a 1 kg sigma blade jacketed mixer. High levels of marc powder required additional cocoa butter to achieve a dry conche consistency. The remaining cocoa butter was added and mixed for 30 minutes to liquefy. Samples were withdrawn for rheology measurement following the standard National Confectioners Association and Chocolate Manufacturers Association (NCA/CMA) method for fluid chocolate (spindle 27, 40°C, confidence of fit > 98% for all measurements). Table 16B shows the ingredient makeup and Casson viscosity and yield values of each chocolate. The particle size distribution of each chocolate as measured by laser diffraction is shown in FIG.3A. The chocolates were then molded into bars and evaluated for sensory attributes. Table 16A. Percentage and particle size of ingredients used in the high-CF base chocolate.

¹Comma-separated values represent independent replicate measurements. ²Values represent calculated amounts of cocoa flavanols from the base chocolate, and do not include flavanols from the added marc. Sensory Method [0136] A group of six panelists (5 males; 1 female; ages 32-60+) with 10-20+ years’ professional experience in the food or dietary supplement industry was used to determine the sensory attributes of the chocolates employing a modified quantitative descriptive analysis. Ten flavor attributes from three flavor categories were evaluated including: 1) retronasal aroma (five attributes; in-mouth); 2) basic taste (four tastes; bitter, sweet, salty, sour); 3) mouthfeel – astringency (pleasant mouthfeel). The flavor attributes evaluated in this study are shown in Tables 17A-C. Table 17A. Five aroma attributes (Retronasal- in-mouth).

Table 17B. Four basic tastes.

Table 17C. Mouthfeel.

[0137] For the sensory evaluation, the panelists were asked to taste each chocolate and asked to score each flavor attribute on a nine-point scale from 0 to 4, in which 0 = not observable, 1 = weak intensity, 2 = moderate intensity, 3 = strong intensity, and 4 = extreme intensity (in 0.5 increments). First, the control chocolate was evaluated and scored for all ten flavor attributes. Then, each test chocolate was evaluated, and the panelists were asked to score the test chocolate’s flavor attributes in relation to the intensity of the same flavor attribute in the control chocolate. For palate cleansing, breaks were taken in between each flavor evaluation. The sensory experiment was conducted in triplicate. The scores for each attribute (8 samples; 10 attributes; 6 panelists in triplicate (18 observations per attribute); 1440 total observations) were compiled. The mean (M) and the standard error of the mean (SEM) were calculated using Microsoft® Excel Version16.21 for Office 360 (Microsoft Corporation, Redman, WA). To compare the intensity of each chocolate flavor attribute, the mean rating of each attribute was evaluated using a one-way analysis of variance (ANOVA). If ANOVA proved to be significant, means were separated with Tukey–Kramer HSD test. All statistical analyses were was performed using JMP Pro 14.0.0 software (SAS Institute, Cary, NC) with a significance level of Į = 0.05. Graphs were prepared using GraphPad Prism version 9.0.0 for Windows (GraphPad Software, San Diego, CA). Results [0138] Chocolates with up to 25% Chardonnay marc exhibited Casson viscosity and yield values similar to the control, demonstrating no negative impacts on flow with the addition of Chardonnay marc (Table 16B). [0139] The flavor and aroma attributes that were significantly different between the different chocolates are shown in FIGS.3B-3I. Cocoa aroma attribute levels decreased at 15% by weight or greater Chardonnay marc (FIG.3B), while fruity aroma attributes increased 10% by weight or greater Chardonnay marc (FIG.3C). The inverse relationship between cocoa and fruity aroma attributes with Chardonnay marc addition is shown in FIG.3D. The roasty aroma attribute was only significantly decreased compared to the control at 37.5% and 50% by weight Chardonnay marc (FIG.3E). Chardonnay marc led to a significant increase in sour taste attributes (FIG.3I) at concentrations of 10% by weight and higher. Interestingly, sweet taste attributes were maintained at acceptable levels at all concentrations of Chardonnay marc, and only significantly decreased compared to the control at 37.5% and 50% by weight Chardonnay marc (FIG.3H). This is surprising, considering that the addition of marc to the base chocolate reduces the overall sugar content of the final chocolate. For example, the 25% Chardonnay marc chocolate showed no significant decrease in sweetness despite a ~40% sugar reduction as compared to the control chocolate (Table 16B). No statistically significant differences were observed in the nutty, caramelized, and salty attributes of the chocolates. [0140] Foods that are high in phenols (e.g., flavanols), such as chocolate, often have an unpleasant, astringent mouthfeel and/or bitterness that needs to be balanced with other ingredients in order to achieve desirable sensory attributes. Additionally, food additives and ingredients that are high in phenols would be expected to increase the astringent mouthfeel and bitterness of foods that are already high in phenols. Surprisingly, despite the addition of Chardonnay marc high in flavanols to a chocolate already high in flavanols, pleasant mouthfeel attributes were maintained with no significant difference from the control at up to 25% by weight Chardonnay marc, and was maintained at acceptable levels up to at least 37.5% Chardonnay marc (FIG.3F). Additionally, bitterness was significantly decreased with the addition of 10% or more Chardonnay marc, even up to 50% Chardonnay marc (FIG.3G). These unexpected results demonstrate the value of Chardonnay marc as a food ingredient to increase the concentration of desired dietary flavanol antioxidants to chocolate while reducing bitterness and maintaining sweetness and a pleasant mouthfeel of the chocolate. Example 8: Sensory characterization of 15% addition of four different fruit marcs (Concord grape, pomegranate, Chardonnay, and blueberry) in dark chocolate high in cocoa flavanols Preparation of Chocolates with Different Fruit Marcs [0141] Batches of chocolate containing Chardonnay, Concord grape, pomegranate, and blueberry marc at a concentration of 15% by weight were produced. Concord grape, pomegranate, and blueberry marcs were obtained and milled to powder. Milling conditions were varied to achieve nominal particle size of 30 microns. The particle size of the marcs before and after milling are shown in Table 18A. The fine-milled 2 Chardonnay marc produced in Example 6 was used to produce the 15% by weight Chardonnay marc chocolate. Chocolates were prepared with each marc using the method described in Example 7 and the high-CF base chocolate described in Table 16A. Table 18B shows the ingredient makeup of the chocolates. The only difference between the base chocolate and the final chocolate with 0% marc was the addition of 9.4% cocoa butter during conching. The particle size distribution of each of the final chocolates is shown in FIG.4A. Table 18A. Particle size of Concord grape, blueberry, and pomeagranate marcs before and after milling.

¹Concord grape, pomegranate, Chardonnay, or blueberry marc. ²Values represent calculated amounts of cocoa flavanols from the base chocolate, and do not include flavanols from the added marc. Sensory Method [0142] A group of six panelists (5 males; 1 female; ages 32-60+) with 10-20+ years’ professional experience in the food or dietary supplement industry was used to determine the sensory attributes of the chocolates employing a modified quantitative descriptive analysis. Twelve flavor attributes from three flavor categories were evaluated including: 1) retronasal aroma (seven attributes; in-mouth), 2) basic taste (four tastes; bitter, sweet, salty, sour); 3) mouthfeel – astringency (pleasant mouthfeel). The flavor attributes evaluated in this study are shown in Tables 19A-C. Table 19A. Seven aroma attributes (Retronasal- in-mouth).

[0143] For the sensory evaluation, the panelists were asked to taste each chocolate and asked to score each flavor attribute on a nine-point scale from 0 to 4, in which 0 = not observable, 1 = weak intensity, 2 = moderate intensity, 3 = strong intensity, and 4 = extreme intensity (in 0.5 increments). First, the control chocolate was evaluated and scored for all twelve flavor attributes. Then, each test chocolate was evaluated, and the panelists were asked to score the test chocolate’s flavor attributes in relation to the intensity of the same flavor attribute in the control chocolate. For palate cleansing, breaks were taken in between each flavor evaluation. The sensory experiment was conducted in triplicate. The scores for each attribute (5 samples; 12 attributes; 6 panelists in triplicate (18 observations per attribute); 1080 total observations) were compiled. The mean (M) and the standard error of the mean (SEM) were calculated using Microsoft® Excel Version16.21 for Office 360 (Microsoft Corporation, Redman, WA). To compare the intensity of each chocolate flavor attribute, the mean rating of each attribute was evaluated using a one-way analysis of variance (ANOVA). If ANOVA proved to be significant, means were separated with Tukey–Kramer HSD test. All statistical analyses were was performed using JMP Pro 14.0.0 software (SAS Institute, Cary, NC) with a significance level of Į = 0.05. Graphs were prepared using GraphPad Prism version 9.0.0 for Windows (GraphPad Software, San Diego, CA). Results [0144] The flavor and aroma attributes of the chocolates that were significantly different are shown in FIGS.4B-4J. All of the marcs significantly decreased cocoa aroma attributes (FIG. 4B) and increased total fruit aroma attributes (FIG.4C) of the chocolate compared to the control. As expected, only the blueberry marc led to a significant increase in detection of blueberry aroma attributes (FIG.4D). Interestingly, Concord and blueberry marcs both led to a significant increase in grape aroma attributes compared to the control chocolate, while the Chardonnay marc did not (FIG.4E). This demonstrates a surprising effectiveness of Chardonnay marc in increasing the overall fruitiness of chocolate without adding a distinct grape flavor. Chocolates with Chardonnay and blueberry marcs had a slight, but not significant, increase in caramelized attributes compared to the control chocolate (FIG.4F). All of the marcs except blueberry led to a significant increase in sour taste attributes compared to the control chocolate (FIG.4J). No statistically significant differences were observed in the roasty, nutty, and salty attributes of the chocolates. [0145] Grape, blueberry, and pomegranate products are all desired by consumers for their high concentrations of antioxidant flavanols and other polyphenols. As discussed in Example 7, one would expect that addition of marcs of these high-flavanol fruits would increase the unpleasant astringent mouthfeel and bitternessof chocolate. Surprisingly, none of the marcs led to a significant decrease in pleasant mouthfeel compared to the control (FIG.4G), and only pomegranate marc led to a significant increase in bitterness (FIG.4H) and a significant decrease in sweetness (FIG.4I), despite an ~25% reduction in sugar content (Table 18B). These results demonstrate that the unexpected effect of delivering desired dietary flavanols to chocolate while maintaining sweetness and pleasant mouthfeel without increasing bitterness is not unique to Chardonnay marc, and may be achieved with other grape and berry marcs. Notably, only Chardonnay marc led to a significant decrease in bitterness (FIG.4H) while maintaining pleasant mouthfeel (FIG.4G) and sweetness (FIG.4H), highlighting its particular effectiveness.
