Description

EDIBLE PONGAMIA COMPOSITIONS, AND METHODS OF PREPARING AND

USING THEREOF

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims priority to U.S. Provisional Patent Application No. 62/910,315, filed October 3, 2019, which is incorporated herein by reference in its entirety.

FIELD

[0002] The present disclosure relates generally to compositions obtained from pongamia oilseeds, and more specifically to pongamia compositions having an optimized nutritional composition, achieved by subjecting pongamia oilseeds to certain processing steps. Such pongamia compositions may be suitable as food or food ingredients to humans and other nonruminant animals, such as poultry, swine, canines and felines.

BACKGROUND

[0003] Growing concerns related to population growth, climate change and the viability of existing agricultural practices over the next several decades have led to a surge in the research and development of alternative food sources to ensure future global food security. Renewable plant-based sources have prompted significant interest as an environmentally friendly and sustainable means to alleviate pressure on the worldwide food supply by providing nutrient- and protein-rich alternatives to animal-derived protein in human diets.

[0004] Millettia pinnata, also known as Pongamia pinnata or Pongamia glabra, or more colloquially as pongamia or karanja, is tree that is common throughout Asia and may provide a major source for future plant-based protein. Pongamia trees use one-tenth of the land as required for soybean plants to produce the same amount of beans. Pongamia trees can grow on degraded soil, and allow for avoidance of deforestation issues created by soybeans. Pongamia also produces much larger amounts of protein and vegetable oil per acre than soybean. Pongamia seedcake, the byproduct of oil extraction from pongamia oil seeds, offers a potential renewable source of protein, carbohydrates and fibers for use in foodstuffs comparable to soy. However, pongamia oilseeds also have other components that are known in the art to have disagreeable taste and odor, including karanjin and pongamol. It is desirable to minimize the amount of karanjin and pongamol in the seedcake for use as a viable food source.

[0005] The widespread use of pongamia-derived foodstuffs is currently prevented by the absence of methods for preparing pongamia compositions having low levels of karanjin and pongamol while maintaining the high nutritional content (proteins, carbohydrates, etc.) intrinsic to the oilseeds. Existing methods for the removal of these undesirable components in pongamia seedcake often require harsh, destructive conditions that reduce and degrade the nutrients to the point that the nutritional value of pongamia is severely impacted. The lack of methods for producing pongamia compositions having the critical balance of preserved nutritional content and sufficiently low levels of anti-nutrients have precluded the incorporation of pongamia-derived protein as a replacement food source on a large enough scale to remain economically feasible.

[0006] Thus, what is desired in the art are commercially viable methods to obtain edible compositions from pongamia oil seeds that retain an optimal nutritional balance, while minimizing components such as karanjin and pongamol.

DETAILED DESCRIPTION

[0015] The following description sets forth exemplary 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. Pongamia Compositions [0016] In some aspects, provided herein are edible compositions obtained from processing pongamia oilseeds to maximize removal certain anti-nutritional components therein, such as karanjin, pongamol and tannins, while optimizing the nutritional balance of other components therein, such as digestible proteins, carbohydrates, antioxidants, and minerals.

[0023] In other embodiments, the composition further comprises other furanoflavonoids that may be present in the pongamia oilseeds from which the pongamia composition was obtained. Such furanoflavonoids may include, for example, lanceolatin, kanjone, pongaglabrone, pongaglabol, ovalifolin, sanaganone, pinnatin, gamatin, pongone, glabone, karanjonol, pongapin, pachycarin, pongaglabol methyl ether, isopongaglabol, methoxyisopongaglabol, pongol methyl ether, millettocalyxin, 6-methoxyisopongaglabol, pongamoside A, pongamoside B, ponganone XI, pongamoside C, glabra I, ovalitenone, ponganone IX, and pongarotene. [0024] In some variations of the foregoing, the pongamia composition has a balance of digestible proteins, carbohydrates, antioxidants, and minerals to increase bioavailability in humans and other non-ruminant animals. [0025] In some variations of the foregoing, the pongamia composition is in the form of meal. In other variations of the foregoing, the pongamia composition is in the form of flour. [0026] In some embodiments, the pongamia compositions of the present disclosure may have (i) a karanjin content, if present, of less than or equal to 100 ppm; (ii) a pongamol content, if present, of less than or equal to 100 ppm; and (iii) a tannin content of less than or equal to 0.5% w/w.

In still other variations, the tannin content is less than or equal to 0.2% w/w, less than or equal to 0.1% w/w, less than or equal to 0.01% w/w, or less than or equal to 0.001% w/w. [0027] In some embodiments of the foregoing wherein the pongamia compositions of the present disclosure may have (i) a karanjin content, if present, of less than or equal to 100 ppm; (ii) a pongamol content, if present, of less than or equal to 100 ppm; and (iii) a tannin content of less than or equal to 0.5% w/w, the pongamia compositions may be further characterized by various organoleptic properties, such as taste, palatability, and sensory acceptability. [0028] For example, color may be indicative of, or a proxy for, the tannin content in the pongamia compositions. In still further embodiments, which may be combined any of the foregoing embodiments, the pongamia compositions described herein may color characteristics as determined by a ultra-violet-visible light spectral absorption profile or visual comparison to suitable color standard (card) (e.g., USDA color standard). In certain embodiments, the pongamia composition is white. Methods of Preparing Pongamia Compositions [0029] The pongamia compositions described herein are obtained from pongamia oilseeds, and undergo certain thermal and mechanical processing steps. With reference to FIG. 1, process 100 is an exemplary process to prepare a pongamia composition. In step 102, pongamia oilseeds are provided. In some variations, providing the oilseeds may further include removing and/or separating the oilseeds from the pods, or shells. The removal of the oilseeds from their pods or shells may involve manual removal or mechanical cracking to open the pods. In certain variations, the separation of oilseeds from their pods or shells may involve manual separation, sieving/screening, or aerodynamic separation (e.g., weight classification by aspiration).

[0030] With reference again to FIG. 1, the pongamia oilseeds are heated at a suitable temperature for a suitable amount of time in step 104, thereby providing treated pongamia oilseeds. The thermal treatment may help to promote the disintegration of the membrane binding the oilseeds to their hulls and, consequently, may facilitate the downstream removal of the hulls from the treated oilseeds. In some embodiments, the temperature and duration of the thermal treatment may influence the compatibility of the downstream dehulled oilseeds with the mechanical pressing process.

[0031] In some embodiments, the oilseeds are heated at a temperature of at least 25°C, at least 30°C, at least 35°C, at least 40°C, at least 50°C, at least 60°C, at least 70°C, at least 75°C, at least 80°C, at least 90°C, at least 100°C, at least 110°C, at least 120°C, at least 125°C, at least 130°C, at least 140°C, at least 150°C, at least 160°C, at least 170°C, at least 175°C, at least 180°C, or at least 190°C. In other embodiments, the oil seeds are heated at a temperature of less than or equal to 200°C, less than or equal to 190°C, less than or equal to 180°C, less than or equal to 170°C, less than or equal to 160°C, less than or equal to 150°C, less than or equal to 140°C, less than or equal to 130°C, less than or equal to 125°C, less than or equal to 120°C, less than or equal to 110°C, less than or equal to 100°C, less than or equal to 90°C, less than or equal to 80°C, or less than or equal to 75°C. In some variations, the oilseeds are heated at a temperature between 25°C and 200°C, between 30°C and 200°C, between 60°C and 200°C, between 60°C and 180°C, between 60°C and 150°C, between 60°C and 120°C, between 80°C and 200°C, between 80°C and 180°C, between 80°C and 150°C, between 80°C and 120°C, between 100°C and 200°C, between 100°C and 180°C, between 100°C and 150°C, between 100°C and 120°C, between 120°C and 200°C, between 120°C and 180°C, between 120°C and 150°C, between 150°C and 200°C, between 150°C and 180°C, or between 180°C and 200°C.

[0032] In some variations, the oilseeds are heated for a period of time of at least 5 minutes, at least 10 minutes, at least 15 minutes, at least 20 minutes, at least 25 minutes, at least 30 minutes, at least 45 minutes, at least 1 hour, at least 90 minutes, at least 120 minutes, at least 150 minutes or at least 180 minutes. In other variations, the oil seeds are heated for a period of time of less than or equal to 1 day, less than or equal to 20 hours, less than or equal to 15 hours, less than or equal to 10 hours, less than or equal to 5 hours, less than or equal to 4 hours, less than or equal to 180 minutes, less than or equal to 120 minutes, less than or equal to 90 minutes, less than or equal to 60 minutes, less than or equal to 45 minutes, less than or equal to 30 minutes, less than or equal to 25 minutes, less than or equal to 20 minutes, less than or equal to 15 minutes, or less than or equal to 10 minutes. In other variations, the oilseeds are heated for a period of time between 5 minutes and 3 hours, between 5 minutes and 2 hours, between 5 minutes and 90 minutes, between 5 minutes and 1 hour, between 5 minutes and 30 minutes, between 5 minutes and 15 minutes, between 15 minutes and 3 hours, between 15 minutes and 2 hours, between 15 minutes and 90 minutes, between 15 minutes and 1 hour, between 15 minutes and 30 minutes, between 30 minutes and 3 hours, between 30 minutes and 2 hours, between 30 minutes and 90 minutes, between 30 minutes and 1 hour, or between 30 minutes and 45 minutes. Suitable temperatures and/or residence times for the thermal treatment may encompass any combination of time and temperature as described herein. For example, in one variation, the oilseeds are heated at a temperature between 25°C and 200°C for a period of time between 5 minutes and 3 hours. In some variations, the oilseeds are heated for a period of time between 5 minutes and 3 hours, between 5 minutes and 2 hours, between 5 minutes and 90 minutes, between 5 minutes and 1 hour, between 5 minutes and 30 minutes, between 5 minutes and 15 minutes, between 15 minutes and 3 hours, between 15 minutes and 2 hours, between 15 minutes and 90 minutes, between 15 minutes and 1 hour, between 15 minutes and 30 minutes, between 30 minutes and 3 hours, between 30 minutes and 2 hours, between 30 minutes and 90 minutes, between 30 minutes and 1 hour, or between 30 minutes and 45 minutes, at a temperature of between 25°C and 200°C, between 30°C and 200°C, between 60°C and 200°C, between 60°C and 180°C, between 60°C and 150°C, between 60°C and 120°C, between 80°C and 200°C, between 80°C and 180°C, between 80°C and 150°C, between 80°C and 120°C, between 100°C and 200°C, between

100°C and 180°C, between 100°C and 150°C, between 100°C and 120°C, between 120°C and 200°C, between 120°C and 180°C, between 120°C and 150°C, between 150°C and 200°C, between 150°C and 180°C, or between 180°C and 200°C.

[0033] With reference again to FIG. 1, the treated oilseeds are then dehulled in step 106. Any suitable techniques known in the art to remove the hulls from the oilseeds may be employed. For example, in some variations, the treated oilseeds are subjected to abrasive force in order to remove the hulls. In certain variations, dehulling may be carried out with an attrition mill or an impeller, or mechanical equivalent. In one variation, the dehulling step does not utilize wet removal methods, such as blanching, alkaline and/or aqueous dissolution. In certain embodiments, the pongamia oilseeds undergo thermal treatment prior to hull removal. In some variations, such thermal treatment is a dry dehulling process, which is distinguished from a wet dehulling process that may involve, for example, blanching. In certain embodiments, the pongamia oilseeds subjected to the thermal treatment and the oilseeds and pongamia composition obtained therefrom as described herein may be characterized by their moisture content. In some variations, the treated oilseeds obtained from the thermal treatment have a moisture content of less than or equal to 20% w/w, less than or equal to 17% w/w, less than or equal to 15% w/w, less than or equal to 12% w/w, less than or equal to 10% w/w, or less than or equal to 8% w/w, without further drying. In other variations, the treated oilseeds obtained from the thermal treatment have a moisture content of between 5% w/w and 20% w/w, between 5% w/w and 17% w/w, between 5% w/w and 15% w/w, between 5% w/w and 12% w/w, between 5% w/w and 10% w/w, between 5% w/w and 8% w/w, between 8% w/w and 20% w/w, between 8% w/w and 17% w/w, between 8% w/w and 15% w/w, between 8% w/w and 12% w/w, between 8% w/w and 10% w/w, between 10% w/w and 20% w/w, between 10% w/w and 17% w/w, between 10% w/w and 15% w/w, between 10% w/w and 12% w/w, between 12% w/w and 20% w/w, between 12% w/w and 17% w/w, between 12% w/w and 15% w/w, between 15% w/w and 20% w/w, between 15% w/w and 17% w/w, or between 17% w/w and 20% w/w, without further drying. In yet other variations, the treated oilseeds obtained from the thermal treatment may be dried in order to control the moisture content prior to mechanical processing to remove oil and obtain a deoiled seedcake (or presscake). [0034] The dehulled oilseeds may be described by any number of characteristics, including for example the weight percentage of oilseeds that are dehulled, the tannin content, the moisture content, or the particle size distribution. In some embodiments, the percentage of oilseeds that are dehulled may be quantified by visual inspection of the covered and uncovered surface area of the oilseeds. In certain variations, the dehulled oilseeds has between 40% w/w and 100% w/w, between 40% and 80% w/w, or between 40% and 70% w/w of oilseeds having less than 50% of the total surface area covered by hull. In certain variations, the dehulled oilseeds have an average tannin content of less than or equal to 0.5% w/w, less than or equal to 0.4 % w/w, or less than or equal to 0.3% w/w.

EXAMPLES [0062] 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 A - Measurement Protocols Example A1: Microwave-Assisted Extraction Method (MAE) for Determination of Concentrations of Karanjin, Pongamol and Other Furanoflavanoids [0063] The following example describes a general protocol for the measurement of karanjin and pongamol concentrations in a pongamia sample. [0064] Microwave-assisted extraction of karanjin and pongamol. 0.5 g pongamia seedcake is added to a microwave extraction tube. Then, 15 mL of either ethyl acetate is added to the sample tubes and vortexed to mix. Next, the samples are extracted using a microwave extractor under the following conditions: 1) ramp for 15 minutes to 70 ºC, 2) hold at 70 ºC for 10 minutes. Once cooled, the supernatant is filtered using filter paper in a Buchner funnel under a vacuum. [0065] Standard solutions for HPLC. Commercially available karanjin and pongamol are mixed with methanol to produce the following HPLC standards: 0.05, 0.1, 0.2, 0.5, 1.0, 5.0, and 20.0 μg/mL. [0066] HPLC instrumentation. HPLC analysis is conducted with a mobile phase consisting of: Solvent A (0.1% Formic acid in HPLC water) and Solvent B (0.1% Formic acid in acetonitrile). The injection volume is 2 μL and the flow rate was 0.75 mL/minute. The column is a C18 5 μm, 50 x 2mm HPLC column. All HPLC analyses are conducted in negative ion mode. The MS parameters are: curtain gas, 30 psi; collision gas, 4 psi; nebulizer gas (GS1), 50 psi; drying gas (GS2), 50 psi; ion spray voltage, 5000; temperature, 500 ºC; declustering potential (DP), 51 V; entrance potential, 10V; collision energy (CE), 60 eV for karanjin and 30 eV for pongamol. [0067] MS/MS quantification of karanjin and pongamol in extract. Multiple reaction monitoring (MRM) ion transitions are monitored for both karanjin and pongamol. The level of karanjin and pongamol present in the extracted samples is calculated using Analyst version 1.6.3. Briefly, the peak area of karanjin and pongamol in the extraction samples is compared with the peak area of the calibration standards to determine the parts per million of karanjin and pongamol.

Example A2: Determination of Hull Removal Percentage and Tannin Content in Pongamia Samples

[0068] The following example describes a general protocol for the measurement of the percentage of hulls present and tannin content in a pongamia sample.

[0069] Hull Removal Percentage. A representative sample of oilseeds to be evaluated for percentage of hull removal is taken. The oilseeds and fragments thereof are sorted into two distinct groups based upon visual assessment of whether the individual oilseed or fragment has retained 50% or greater of its original hull covering. The two groups of oilseeds are separately weighed. The percentage of successful hull removal is calculated as the weight of oilseeds having less than 50% of the original hull covering intact over the sum of the weights for both groups of oilseeds, multiplied by 100%.

[0070] Tannin Content. The measurement protocol of tannin content in pongamia oilseeds and downstream pongamia products (e.g., deoiled seedcake ) was carried out in accordance with ISO standard protocol for determination of tannin content in sorghum (ISO 9648, UV spectrophotometric method). The sample to be tested is shaken with dimethylformamide. The dimethylformamide mixture is centrifuged, and the supernatant isolated. Ferric ammonium citrate and ammonia are added to an aliquot of the supernatant liquid. The absorbance of the solution is determined by UV spectrophotometric measurement at 525 nm, and the tannic content determined using a calibration curve prepared using tannic acid.

Example A3: Determination of Composition Profile

[0071] The following example describes general protocols to assay the compositional profile of a pongamia sample, for content of amino acids and other macronutrients.

[0072] Total protein. Total protein content is determined by placing the pongamia seedcake samples in the combustion chamber of a protein analyzer, measuring the total nitrogen content of the gas produced by combustion, and calculating the protein from the observed nitrogen content using a standard nitrogen conversion factor (protein content = 6.25 x nitrogen content). [0073] Total ash. The total ash content is determined by placing the seedcake samples (2g) into a crucible, dying the samples in an oven, ashing the samples in a muffle furnace at 600^, and measuring the weight of the ash (AOAC 942.05 reference method). [0074] Total moisture content. The total moisture content is determined by heating a weighed sample at 130^ for 2 hours in a forced draft oven, and determining the difference in sample weight, with the percentage difference calculated as moisture content (AOCS BA 2A- 38 reference method). [0075] Total fat content. The total fat content was determined by solvent extraction under reflux with petroleum ether (AOCS BA3-38 reference method, modified). [0076] Total carbohydrate. Total carbohydrate content is calculated as the remaining percentage of the pongamia seedcake (100%) less the sum of the total ash content (%), total protein content (%), total moisture content (%), and total fat (%). Example B - Large-Scale Extraction Methods Example B1 - Preparation of Dehulled, Deoiled Pongamia Composition Thermomechanical Treatment [0077] Pongamia pods were harvested and the oilseeds were removed from the pods. The isolated oilseeds were then subjected to various heat treatments at different temperatures (60^, 120^, 150^, and 180^) for different durations of time (5-180 minutes). The thermal treatment was achieved by placing the pongamia oilseeds into aluminum baking trays (49.7cm x 29.5cm x 8.1 cm) with perforated bases at 75% capacity and placing the filled trays in a forced convection oven pre-heated to the indicated temperature. [0078] Fourteen separate combination of temperatures and times were evaluated for the thermal treatment as shown in Table 8 below. In addition to the fourteen trials, a 100 kilogram-scale run was also carried out under the same conditions as trial number 013. As a control, pongamia oilseeds obtained from the same harvest group as the oilseeds evaluated in the fourteen trials were kept under ambient conditions without thermomechanical treatment. [0079] Following thermal treatment, the heat-treated oilseeds were moved immediately into and passed through an impact huller (Codema VSH 2096, 5 hp motor, rotating impeller) for removal of hulls. The oilseeds from each of the fourteen trials passed through the impact huller. After dehulling, the oilseeds were removed from the impact huller and placed into a multi-aspirator (Kice 6E-6 Aspirator, 5 hp fan, cyclone, rotary airlock, 6” ducting) to separate hulls from the dehulled oilseeds. [0080] The percentage of dehulled oilseeds obtained from the procedure was assessed according to the protocol described in Example A2 above. The tannin content of the dehulled test samples was also determined by the protocol described in Example A2 above. [0081] Table 1 shows the results of percentage of pongamia oilseeds dehulled and measured tannin content of the dehulled seeds for the fourteen trials and large-scale trial conducted. Table 1

Mechanical Pressing and Solvent Extraction [0082] Following the removal of hulls from the oilseeds, the dehulled oilseeds were subjected to mechanical pressing to remove pongamia oil. The dehulled oilseeds were passed through a small-scale mechanical expeller press (Taby Model 40A Expeller Press). The dehulled oilseeds processed under the conditions above were found to be compatible with the small-scale mechanical expeller press, resulting in an oil stream and a separate solid deoiled seedcake. Table 2 below shows the mass percentage of oil removed from a sample of dehulled oilseeds treated in Table 1 above.

Table 2

[0083] Dehulled, deoiled seedcake (trial number 013) was extracted with ethyl acetate in an immersion extractor (3-hour residence time, 5:1 solvent: feed ratio). After solvent extraction and removal of the miscella, the resulting ethyl acetate-extracted pongamia meal was analyzed for karanjin concentration, pongamol concentration and oil content as described in the protocols for Examples A1 and A3 above. The resulting ethyl acetate-extracted pongamia meal was measured as having 17 ppm karanjin, 10 ppm pongamol, and 0.80% residual oil.
