Definitions

  • a CONSUMABLE GEL FOR HEALTH This invention relates to a dosage form comprising one or more health ingredients, particularly, but not exclusively, dietary, nutritional or pharmaceutical ingredients.
  • the dosage form is a stable, shearable, gel capable of delivering, particularly, multiple health ingredients in a single dosage form including at least one ingredient that requires taste masking, such as exemplified by bergamot, a bitter tasting ingredient.
  • the dosage form may be used in human or animal health.
  • the dosage form is, particularly, but not exclusively, capable of delivering high doses of dietary, nutritional or pharmaceutical ingredients including: water soluble, water insoluble and/ or lipid soluble ingredients, in a single delivery vehicle which would not readily lend themselves to delivery via tablets or capsules.
  • “high” is meant at least 1g of one or more health ingredients, although the at least one ingredient that requires taste masking may be present in amounts of from 0.1g, through 0.25g and 0.5g to 1g or more.
  • Taste masking is achieved through the use of a high concentration oil/ water emulsion which is stabilised in a shearable gel and which releases its’ load when sheared, the oil articulsion droplets providing a temporary coating on the tongue blunting the taste of the ingredient requiring masking.
  • “high concentration” oil/ water emulsion is meant at least or over 14% by weight of the lipid based carrier as compared to the water content of the dosage form.
  • BACKGROUND [0006] One of the most important factors in successfully developing health ingredients, particularly dietary, nutritional or pharmaceutical ingredients is ensuring patient compliance.
  • multiple product formats are used to deliver each of multiple e.g. nutritional or other health, e.g. active pharmaceutical ingredients (API’s), products. The varied nature and number of such products leads to significant variability in compliance.
  • API active pharmaceutical ingredients
  • These health products, dietary, nutritional or pharmaceutical products may be preventative or curative in nature. They include: prescription products, over-the-counter (OTC) products, and nutraceuticals and dietary supplements including, for example, products containing: vitamins, minerals, elements, proteins, carbohydrates, lipids, extracts of plant origin e.g.
  • the organoleptic properties may relate to aspects of product taste, product consistency, product texture, product mouth feel, longevity of taste and any other organoleptic sensation. Ingredients with unpleasant tastes are particular challenging and the focus of the claimed invention addresses products including such ingredient(s).
  • Some products require a separate drink to facilitate swallowing or to wash residues from the mouth, or a separate solid composition to be co-administered.
  • Examples include: replacement sugar products for hypoglycaemia, and whey protein, which is poorly dispersed in liquids, and is additionally required in large volumes.
  • a delivery device may be required, such as a spoon, a syringe, or some other metering device to aid consumption and dose delivery.
  • These highly viscous pastes or gel products are those that will flow but tend to flow slowly, with a high internal resistance and a consistency like honey or ketchup.
  • These known highly viscous pastes may be Newtonian or non-Newtonian fluids and may be shear thinning or shear thickening in nature. However, they all share the property that despite a degree of resistance, they plastically deform under stress – even where such behaviour is also known to have a threshold, such as Bingham plastic behaviour.
  • these viscous pastes have a viscosity between about 5000 and about 50,000 cP.
  • set refers to jelly materials that set, and do not exhibit plastic behaviour upon stress, but rather behave elastically upon stress, to a failure point where the structure of the jelly breaks to irreversibly create new interfaces.
  • Applicant addressed this general problem in WO2019/215641 by developing a base gel comprising two different gelling agents: x a primary gelling agent which was an agarose-based polymer gelling agent, such as, an agar, and x a polyvalent ion gelled polymer which was an alginate-based polymer gelling agent, such as, but not limited to calcium alginate.
  • x a primary gelling agent which was an agarose-based polymer gelling agent, such as, an agar
  • polyvalent ion gelled polymer which was an alginate-based polymer gelling agent, such as, but not limited to calcium alginate.
  • the agarose-based polymer provides the key functional characteristics, namely it forms, in the amounts provided, a firm hydrated gel, with a bloom grade of between 100 and 250, which does not exhibit plastic behaviour upon stress, but rather behaves elastically upon stress, to a failure point where the structure of the gel breaks or shears irreversibly releasing water and creating new interfaces, making it more fluid when ingested, such that it is a drinkable gel.
  • the specification teaches forming emulsions incorporating up to 10% by weight of an oil or lipophilic components based on the water content of the dosage form.
  • This application addresses a specific challenge of taste masking in agarose-based polymer gels (which can be sheared to release water) and incorporate oils.
  • an oral dosage form comprising x an ingredient requiring taste masking, x a first gelling agent, which is an agarose-based polymer gelling agent present in concentrations of between 0.001g (1mg) and 0.03g (30mg) per gram of water which concentration ensures hydration of, and the formation of, a firm gel with a bloom of between 100 and 250, and which does not exhibit plastic behaviour upon stress, but rather behaves elastically upon stress, to a failure point where the structure of the gel breaks or shears to irreversibly create new interfaces, making it more fluid when ingested, such that it is a drinkable gel; and x an oil/ water
  • the first gelling agent which is an agarose-based polymer gelling agent is present in concentrations of between 0.001g (1mg) and 0.02g (20mg) per gram of water
  • the premise of the invention is based around ensuring droplets of emulsified oil are released from the gel when it shears such that they temporarily coat the tongue, blunting the taste of any ingredient(s) incorporated in the gel which are unpleasant (to receptors on the tongue).
  • the invention requires sufficient lipid-based carrier (oil) and emulsifier to achieve its’ function as an effective taste masker whilst retaining the stability of the gel.
  • stable By stable is meant there is no phase separation of the oil and water components of the emulsion, and that the ingredient(s) did not precipitate out. [0029] Selecting an oil that also provides desirable organoleptic properties was also required. [0030] Any suitable oil including vegetable oils, seed oils, and marine oils can be used together with blends thereof. [0031] Preferred oils were olive oil, sunflower oil, canola oil, coconut oil and oils containing medium chain triglycerides. Olive oil was particularly favoured for its neutral and organoleptic properties.
  • the invention can be used with a single agarose based gelling agent, and it is the greater concentration of the emulsified oil that provides the effective taste masking – since it is the release of the emulsified oil on shearing that provides a “protective” (taste blunting) coating to the tongue.
  • Agar proved particularly beneficial in providing enhanced stability.
  • Applicant has determined that the optimum concentration of emulsified oil (by weight) is between 14% and 28% by weight of oil to water, although Applicant has determined that it is possible, in some circumstances, to get as much as 30% by wt of oil to water.
  • the emulsified oil comprises at least 20% by weight the lipid based carrier.
  • the incorporation of an emulsifier further improves performance.
  • a preferred emulsifier is one of lecithin, polyethylene glycol (PEG) and Polysorbate 80.
  • the emulsifier should be present in an amount of from 0.1% to as much as 6.0% by weight. A preferred range is from 3% to 5%. Many other benefits of these shearable gels are as disclosed in WO2019/215641.
  • a firm gel is a “set” gel or jelly characterised in an industrial and scientific context by the Bloom test, which is used to provide a relative firmness and strength of these gels. This test originated in 1925 by Oscar T.
  • Bloom The test determines the weight in grams needed by a specified plunger (normally with a diameter of 0.5 inch (11mm) to depress the surface of the gel by 4 mm, without irreversibly breaking the gel to create new interfaces, at a specified temperature. This result is the Bloom grade. A higher number indicates a stiffer product. For example, gelatin used in food usually runs from 125 Bloom to 250 Bloom. [0039] For the purpose of this document the terms gel and jelly are interchangeable. [0040] A set gel or jelly is somewhat elastic which means that under stress they deform, but when that stress is released they substantially return back to their original form.
  • the oral dosage form of the invention may typically be provided in a volume of between 5ml and 250ml, depending on use, and is delivered from a container.
  • agarose-based polymer gelling agent is preferaly, an agar.
  • the agarose-based polymer gelling agent also advantageously behaves as an emulsifier so that additional emulsifiers are required in lesser amounts.
  • a polyvalent ion gelled polymer when used, is most preferably an alginate-based polymer gelling agent, such as, but not limited to calcium alginate. Alternatives include, guar gum, gellan gum, xanthan gum, pectin and kudzu.
  • a particularly favoured combination of gelling agents comprise agar as the primary gelling agent and calcium alginate as the secondary gelling agent.
  • Agar consists of a mixture of two polysaccharides: agarose and agaropectin, with agarose making up about 70% of the mixture.
  • Agarose is a linear polymer, made up of repeating units of agarobiose, a disaccharide made up of D-galactose and 3,6-anhydro-L- galactopyranose.
  • Agaropectin is a heterogeneous mixture of smaller molecules that occur in lesser amounts and is made up of alternating units of D-galactose and L-galactose heavily modified with acidic side-groups, such as sulphate and pyruvate. Any known variant of Agar may be used in the invention. [0049] Agar exhibits hysteresis, melting at 85°C and solidifying at from 32°C to 40°C.
  • the gelling also helps provide stability, at room temperature (and above), meaning cold storage can be avoided.
  • the most common alginate used in food is sodium alginate.
  • sodium alginate In order to form a gel, sodium alginate needs to come into contact with divalent ions, such as calcium (Ca2+).
  • a calcium salt such as the chloride or citrate
  • a gel forms as the sodium ions (Na+) are exchanged with calcium ions (Ca2+) and the polymers become crosslinked.
  • the divalent ions such as calcium
  • monovalent ions such as sodium
  • the gels are either thermo-reversible (at low concentrations) or thermos-irreversible (at high concentrations).
  • Alginic acid is a linear copolymer with homo-polymeric blocks of (1-4)-OLQNHG ⁇ -D- mannuronate (M), and its C-5 epimer, ⁇ -L-guluronate (G), which are covalently linked together in different sequences or blocks.
  • Sodium alginate is the sodium salt of alginic acid. Its empirical formula is NaC6H7O6. Sodium alginate is a gum, extracted from the cell walls of brown algae.
  • Potassium alginate is a chemical compound that is the potassium salt of alginic acid. Its empirical chemical formula is KC 6 H 7 O 6 .
  • Calcium alginate made from sodium alginate from which the sodium ion has been removed and replaced with calcium, has the chemical formula C 12 H 14 CaO 12 .
  • the gel formulation of the invention can be used to deliver unpleasant tasting ingredients, including those which are: i) Water soluble; ii) Water insoluble; or iii) Lipids [0057] .
  • a dose including upwards of 0.1g of at least one ingredient requiring taste masking and optionally, between 1g and 40g of additional ingredients is delivered in a volume of between 5 and 45 ml of gel.
  • These ingredients can include other nutraceutical or health ingredients.
  • the base gel formulation can be used to load a single ingredient requiring taste masking, but the format makes it particularly effective for delivering multiple health ingredients, including the ingredient requiring taste masking, in a simple to take, simple to use dosage form which can retain ingredients which would typically be difficult to formulate in a single dosage form due to their different properties and can be administered orally by squeezing or sucking the gel from its container.
  • a single ingredient requiring taste masking is most likely to be delivered in a smaller volume format (5ml to 25ml), whereas a larger format (25ml to 250ml) is preferred where multiple health ingredients, particularly those required in large doses, and are required alongside the ingredient(s) requiring taste masking.
  • Such multiple health ingredients include, for example, proteins, carbohydrates, dietary fats, vitamins and minerals.
  • the Proteins optionally include: milk protein concentrate, whey protein concentrate, soya protein isolate, and sodium caseinate which may additionally include Amino Acids such as one or more of: L-Glutamine, L-Glycine, L-Leucine, L-Isoleucine, L-Valine, Beta Alanine, L-Arginine, and Taurine.
  • the Carbohydrates optionally include, for example: maltodextrin, inulin, fructose, and glucose syrup.

  • the gel of the is used to deliver ingredients in the form of an entrapped stable emulsion.
  • the lipid component for example, sunflower or olive oil
  • the lipid component is emulsified with the water, usually with stirring, and then caused to gel with the agar. Additional emulsifying agents may be added to facilitate the emulsification prior to gelling.
  • Typical food grade or pharmaceutical grade emulsifiers such as, for example a lecithin, esters of monoglycerides of fatty acids and mono, di and tri glycerides of fatty acids are added.
  • the provision of multi-phase combinations can be accomodated. For example, an ingredient may be more stable in an oil in water emulsion.
  • the set gel formed can trap & immobilise multiple phases enhancing stability as well as e.g. masking taste.
  • the set gel is easily sheared during delivery to form new wet interfaces thereby facilitating delivery and taste masking through the release of the emulsion.
  • the formulation In its stored state the formulation has a firm jelly form, is stable at room temperature, but when sucked or otherwise subjected to a gentle force, shears to create new wet interfaces which facilitate swallowing. Swallowing is eased because the gel interfaces created are slippery because they are inherently wet, due to the water within the structure.
  • This novel formulation provides a chemically and physically stable matrix which can be used to entrap water soluble components, non-water soluble lipids, and lipid soluble components alike and provide effective taste masking.
  • the gels of the present invention provide minimal residues, other than displaced water, and are very much easier to swallow as a set jelly will shear on sucking in contrast to alternative solid/semi-solid formats that are plastic (not elastic).
  • the shear because they shear, they release components quickly, even in high doses, and the released emulsion provides additional taste masking.
  • the platform is highly flexible in allowing different health ingredients to be provided in combinations in a single dosage form which has benefits over the alternatives currently on offer.
  • an alginate means that some beneficial calcium salts can be incorporated as part of the gelling process.
  • Calcium citrate may also enhance flavour.
  • Solid suspensions may include nano-milled materials, such as, curcumin or glucosamine in a format which may enhance their bioavailability.
  • Agar provides clear gels, without coloured specks. However, Agar and alginate gels are also visually very clear, but more importantly the alginate cross links provide a more structured gel with a different gelling mechanism to the carbohydrate non-ionic gelled polymers improving versatility and performance.
  • Agar and Alginate should be used in particular ratios (w/w).
  • the preferred ratios favour an excess of agar to alginate, and thus a ratio of between 8:1 to greater than 1:1, more preferably 5:1 to greater than 1:1 and most preferably about 3: greater than 1 Agar to Alginate is preferred.
  • the Agar acts as an emulsifier and gelling agent, whilst the alginate together with the metal 2+ ions (Ca2+, Mg2+, Zn2+) form a structured gel counteracting the effect of these ions where only Agar is present.
  • Agars and alginates are both suitable for vegans, vegetarians and most religious diets whereas gelatine is not, as it’s an animal protein, usually obtained from pigs.
  • the advantage of combining agar and alginate gels is that they are less sensitive to temperature effects than other gelling agents. They are also less affected by components that may inhibit gelation, such as oils, changes in pH, and high concentrations of complex carbohydrates, such as, maltodextrins.
  • Agar and alginate gels also tend to be faster setting, which is an advantage in manufacturing, facilitating faster and more robust production.
  • the lipids used in the practising of the invention included any suitable food grade oil of animal or plant origin. Non-limiting examples include: corn oil, olive oil, sunflower oil, and coconut oil. The lipid material may advantageously include lipid vitamins such as any of vitamin D or vitamin E.
  • Other preferred features include [0088] A dosage form including one or more health ingredients which are water soluble ingredients and lipid soluble ingredients. [0089] A dosage form wherein the one or more water soluble health ingredients are selected from the group comprising or consisting of water soluble vitamins, carbohydrates, sugars and amino acids.
  • a dosage form wherein the one or more lipid-soluble ingredients are selected from the group comprising or consisting of: oils, particularly fish and algal oils, DHA, EPA and lipid soluble vitamins D and E.
  • a dosage form comprising one or more of a protein, vitamin, mineral, trace elements and a plant or marine extracts.
  • a dosage form further comprising a second gelling agent which is a polyvalent ion gelled polymer gelling agent which is an alginate-based polymer gelling agent.
  • the first gelling agent is present in an amount greater than the second gelling agent and more preferably still the agarose-based polymer gelling agent and alginate-based polymer gelling agent are present in a ratio of from greater than 1:1 to 3:1.
  • the dosage form is packaged in either: a pouch with an opening for facilitating the drinking of the gel by squeezing and/ or sucking; a sachet or straw; a syringe; or any other packaging facilitating delivery by sucking, squeezing or pushing the gel from the packaging.
  • Benefits of the invention include: x Taste masking: The gels of the invention allows any mixture of nutrients and most poor, strong & unpleasant flavours – such as bitterness, sweetness, fish oils, curcumin (spice/peppery) to be masked. x Large volumes of nutrients may additionally be formulated in one easy to consume dosage form: Multiple ingredients and large doses can be combined in a single dosage form.
  • x Overcomes choking risks posed by tablets Gels are much easier to swallow than pills. The format aids all swallowing issues, whether young children or the elderly or merely those who have a predisposed swallowing problem.
  • x Includes water as an ingredient. The presence of “locked up” but “releasable” water also ensure hydration is achieved, even if released as an emulsion, and no additional fluids are required to enable the product to be swallowed. This also helps aid digestion and provides an improved mouth feel.
  • Fig 1 is an illustration of a dispensing dosage form of the invention.
  • DETAILED DESCRIPTION [00100] The general process for the preparation of a gel formulation is set out in Example 1 below: Example 1 Production methodology [00101] Any water-soluble ingredients are dissolved in water first. These may include a nutritional ingredient such as glucose, as well as preservatives and dilute acids (for pH control). An exemplary preservative is potassium sorbate, and an exemplary pH control agent, if required, is a weak acid, such as, citric acid, ascorbic acid, acetic acid or dilute HCl.
  • the solution is preferably stirred and heated to near boiling.
  • the agar and optionally sodium alginate are added slowly, to allow for gradual hydration, with steady constant stirring, ensuring satisfactory dispersion or dissolution.
  • the dispersion or solution is kept at or around boiling point for a time, between 4-5 minutes, sufficient to ensure proper hydration, especially of the agar.
  • a separate emulsion is formed oil , water and any other ingredient to be incorporated into the emulsion.
  • the two components are then mixed and the finished product is filled into e.g. sachets and allowed to cool such that it forms a firm gel.
  • the sachet may be a simple sachet or tube for small volumes (5-25ml) or for larger volumes (25 to 250ml) a pouch, as illustrated in Fig 1.
  • the pouch (1) is formed from, for example, plastics or foil layers that are sealed together around an edge (3) incorporating a filling and dispensing aperture comprising a plug (4), spout (5) and cap (6).
  • the pouch is filled through the mouth piece (5) and is secured with a cap (6) which may be provided with a frangible seal.
  • the subject removes the cap and drinks the gel by squeezing it and/ or sucking it from the pouch (1) through the spout (5).
  • Alternative packaging for delivery may include a sachet or straw; a syringe; or any other packaging facilitating delivery by sucking, squeezing or pushing the gel from the packaging.
  • a sachet or straw When preparing the gel it is desirable to limit the heating period to minimise water loss from evaporation as excessive evaporation can lead to product variability.
  • the agar is used in concentrations of between 0.001g (1mg) and 0.02g (20mg) per gram of water.
  • the alginate is used in concentrations of between 0.0005g (0.05mg) and 0.01g (10mg) per gram of water. More preferably between 0.001g (1mg) and (0.008g (8mg) per gram of water, and most preferably between 0.001g (1mg) and 0.005g (5mg) per gram of water.
  • a source of divalent ions is added to enhance the alginate gel formation.
  • Suitable ingredients include calcium, zinc and/ or magnesium salts.
  • calcium citrate, magnesium citrate or zinc citrate are good forms of soluble salts and can also provide mineral supplementation. Other salts may however be used.
  • Favoured lipids for forming the emulsion are neutral oils such as olive oil and sunflower oil. Typically, the lipid level is added in concentrations of from 14 to 28%, but in certain circumstances up to 30%, w/w of the total water. The water component may be “split” and the gel and emulsion mixed.
  • a mechanical homogeniser such as a Silverson homogeniser, is advantageously used to facilitate the formation of an emulsion.
  • any known food grade emulsifier may be added to improve the emulsion quality and stability, such as, for example, a lecithin.
  • the emulsifier is non-animal sourced, such as soya lecithin, rather than egg lecithin.
  • the emulsion is, as noted above, made as a separate cool water mix precursor, and is combined with a separate hot agar in water precursor, (the water being split as appropriate) to speed cooling and gel formation.
  • Further components may be dissolved or dispersed into the gel or emulsion. Where a nutritional component is neither water or lipid soluble, this may be prepared as a suspension in either lipid or water.
  • this component is milled to a fine particle size, as this may improve suspension stability, and may also improve bioavailability.
  • the insoluble component may be milled in wet or dry conditions, and may be ball milled, or media milled or nano-milled or milled in a high shear homogeniser. The milling may be conducted in the presence of a milling aid, such as leucine, sodium lauryl sulphate, and metal stearates. [00115] After heating, this liquid formulation can be metered hot into the desired containers and allowed to set as a gel. [00116] More specifically for e.g.
  • the gel production process involves the following: [00118] Weigh the non-gelling agents (e.g. glucose, potassium sorbate, water) in appropriate scaled quantities and add them to a suitable mixing vessel, in the order of e.g. Glucose (or other carbohydrate) as required; potassium sorbate or other preservative as needed, and water. [00119] Apply steady stirring, e.g. at lab scale this is a magnetic stirrer bar. Cover to minimise evaporation and water loss. [00120] Pre-weigh the specified nutrients required for composition. Mix these non-gelling ingredients while applying heat to the vessel contents.
  • the non-gelling agents e.g. glucose, potassium sorbate, water
  • the Bloom test is used to characterise the resulting grade of the set gel.
  • a Bloom grade of at least 100 through 110, 120, 130 and 140 is obtained.
  • a Bloom grade of less than 250, less than 220, less than 200 to less than 180 is obtained.
  • An optimal Bloom grade of between 140 and 180 is desired.
  • a preferred base gel, into which a plurality of ingredients promoting health or well- being (not shown) are added, particularly nutritional ingredients, comprises agar because of its water releasing ability.
  • Example 1 it is taught that lipid may be added to the formulations described therein in amounts up to 10% w/w of the water (i.e to 2.5g in 25ml of water.)
  • Example 2 therein teaches a formulation with 0.5g of omega 3 in 24g of water (approx.2%) and in Examples 4 to 5 the omega 3 level is 1g in 24g of water (approx.4%).
  • Applicant found that with a bitter testing ingredient, such as bergamot, the oil and emulsifier, also present, did not adequately taste mask the product at such concentrations. They therefore undertook a series of experiments to see how they might better address the taste masking of ingredients in water releasing gels.
  • Example 2a Starting formulation (no emulsion) Sample 1C - pH adjusted 1 [00131] In taste tests this product was very bitter. [00132] Applicant therefore decided to incorporate the ingredient with an offensive taste profile (exemplified with bergamot) into an emulsion as per Example 2b.
  • Example 2b Sample 4C - Emulsion with low oil Ingredient Required mass 17 [ ] s po uc, c e o ae emulsion had a concentration of 0.3% w/w with water (0.08/25 x 100) did not improve the taste profile.
  • Example 2c through 2f they increased the oil level in stages through 1.5%, 4.5%, 7.5% to a maximum of 10.5%.
  • Example 2c (Sample 4d) Sample - Emulsion with increasing oil I di t R i d U it
  • Example 2d Sample - Emulsion with increasing oil
  • Example 2e Sample - Emulsion with increasing oil
  • Example 2f Sample 4f - Emulsion with increasing oil I di t R i d U it [00135]
  • Example 2g they explored incorporating Bergamot into variants of a ketogenic product they were developing (very high lipid content).
  • Example 2g (5c) Sample 5C - 1/2 Keto Emulsion Sunflower oil 3 g Agar 0.24 g n had a concentration of 14% (3/21.5 x 100) did significantly improve the taste profile. The bitterness was reduced, but was still noticeable. Significantly, the immediate bitter taste disappeared very quickly. Thus, the higher concentration of lipid muted the bitterness. [00138] Based on the above finding Applicant pushed the oil content even higher to determine the impact on both taste and stability and the results are illustrated in Examples 2h to 2j.
  • Example 2h (16% oil/water emulsion) Ingredient Required Mass Unit Ber amet 47% BPF 100
  • a further improvement in taste was noted and the olive oil was considered a more palatable oil with better organoleptic properties than the sunflower oil.
  • Example 2i (7b) (20% oil/water emulsion) Ingredient Required Mass Unit
  • Example 2j (7c) (24% oil/water emulsion) Ingredient Required Mass Bergamet 47% BPF 1.00 g Bot Exampes and j were abe to success u y taste mask the bitterness of bergamot. They were also stable, by which is meant their was no phase separation of the oil and water components of the emulsion, and that the ingredient(s) did not precipitate out.
