DETAILED DESCRIPTION

[0041] As noted above, the present disclosure describes colored particulate materials having differing solubilities or dissolution rates and improved color-changing food and beverage products comprising the colored particulate materials. In some aspects, food and beverage products formulated with the colored particulate materials having differing solubilities or dissolution rates provide advantages over existing food and beverage products formulated with color-changing components not characterized by different color encapsulation matrices. Such advantages can include, for example, consistent color profiles with substantially no unexpected and undesirable ingredient interactions or color bleed. The colored particulate materials can impart unique and entertaining color change effects in food and beverage products when exposed to an aqueous environment. For example, the colored particulate materials might, when exposed to an aqueous environment, provide a first color followed by a second, distinct color, and the second color may be followed by a third color that is distinct from both the first and second colors. Having a multitude of differently colored particulate materials with different dissolutions rates can provide an economical means of controlled and sustained color change in comparison to other approaches to color-changing foods and beverages. Such sequential changes in food and beverage products can provide a novel effect desirable to consumers.

I. Colored Compositions

[0042] Disclosed herein, in some aspects, are colored compositions including colored particulate materials having differing dissolution rates and color-changing food and beverage products comprising the colored particulate materials having differing dissolution rates. The colored particulate materials can be characterized by different matrices that encapsulate the color. The different matrices can comprise components having differing solubilities and therefore different dissolution rates to provide the differing dissolution rates of the colored particulate materials. The particulate materials can include a plurality of particles, where each particle in the plurality includes a matrix and a coloring agent.

[0043] Each of the particles of each plurality can have a diameter of about 0.1 to about 5 mm, e.g., at least, at most, exactly, or between any two of 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.25, 3.5, 3.75, 4, 4.25, 4.5, 4.75, or 5 mm. Particle size and shape have an effect on particle solubility or dissolution rate, color release, caking, and color stability. Particle size can be modified according to desired color release or dissolution rates, e.g., smaller particles dissolve faster than larger particles, but particles should not be so large as to result in a gritty mouthfeel from residual undissolved particles when added to a liquid as recommended when added to a solvent as recommended. In some aspects, particles in one plurality of particles are different in size than particles in one or more other pluralities of particles. In some aspects, particles in one plurality of particles are the same size as particles in each of the other pluralities of particles.

[0044] Generally, each of the particles of each plurality are spherical, but other shaped particles can be used if desired. Non-liming particle shapes include spherical particles, nearly spherical particles, half-sphere particles, rods, cylindrical particles, flakes, football-shaped particles, star-shaped particles, heart-shaped particles, crescent moon-shaped particles, and the like.

[0045] The particle size and shape distribution may be measured or evaluated in a number of ways known in the art, including but not limited to the following methods: direct measurement with a caliper, sieve analysis, light scattering methods, microscopy, optical projection methods accompanied with image analysis. The particle size distribution may be defined as a distribution of particles by their size, surface area, weight, volume, color, or any other characteristic of interest.

[0046] In one aspect, the width of the particle shape and size distribution is such that 90% of the particles by weight do not deviate in size from the mean value by more than 50% of the mean value. In another aspect, 90% of the particles by weight do not deviate in size from the mean value by more than 30% of the mean value. In yet another aspect, 90% of the particles by weight do not deviate in size from the mean value by more than 20% of the mean value. For example, if the mean particle size is 500 microns, and 90% of the particles by weight do not deviate in size from the mean value by more than 20% of the mean value, then 90% of the particles by weight would have a size between 400 and 600 microns. If the shape of the particles is not spherical then the same specification may be applied to each characteristic dimension of the particles. For example, if the particles are cylindrical rods, then 20% deviation is applied to each characteristic dimension, namely, to the length of the rods as well as to their diameter.

[0047] The environment in which the particles may be dispersed or dissolved can be aqueous-based, alcohol-based, or any other suitable liquid solvent for the ingredients. As used herein, the term water-soluble includes both water-soluble and water dispersible materials. The proportion of solvent generally will be that sufficient to permit solubilization or dissolution of the ingredients and to provide the desired strength or dilution of the coloring agents.

A. Matrices

[0048] At least a portion of the outer surface of each particle in each plurality of particles disclosed herein is defined by a matrix, where the matrix comprises edible, soluble materials (e.g., carbohydrates, gels, proteins, lipids, and the like). In some aspects, the materials used in the matrices are soluble or dispersible in a selected solvent and do not create a gritty mouthfeel or significantly affect the clarity of the food or beverage when such an effect on mouthfeel or clarity is not intended. In some aspects, the particle matrices comprise one or more food safe polymers, e.g., one or more hydrocolloids, and one or more sugars.

[0049] The colored compositions can comprise one, two, three, or more pluralities of particles. Each plurality of particles can be characterized by a dissolution rate that is different from the dissolution rates of each of the other pluralities of particles. For example, in a colored composition including a first plurality of particles, a second plurality of particles, and a third plurality of particles, the dissolution rate of a first plurality of particles can be higher than the dissolution rate of a second plurality of particles and a third plurality of particles, and the dissolution rate of the third plurality of particles can be lower than the dissolution rate of the first plurality of particles and higher than the dissolution rate of the second plurality of particles. Each plurality of particles can be characterized by a matrix that is different from the matrices of each of the other pluralities of particles, and the dissolution rate of each of the particles can be a function of the solubility or dissolution rate of each of the particle matrix components and/or the size of the particles. In some aspects, fast-dissolving high solubility matrix components have a dissolution rate of at least, at most, exactly, or between any two of <1, 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, or 60 seconds. In some aspects, matrix components having moderate solubility have a dissolution rate of at least, at most, exactly, or between any two of 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 minutes. In some aspects, slow-dissolving low solubility matrix components have a dissolution rate of at least, at most, exactly, or between any two of 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 minutes.

[0050] The particle matrices can include one or more food-safe polymers that dissolve in an aqueous environment, e.g., in water. The one or more food-safe polymers may be one or more hydrocolloids. The one or more hydrocolloids may be one or more starches, one or more gums, one or more maltodextrins, or a combination thereof. Non-limiting examples of hydrocolloids that may be used in the matrices disclosed herein include starch, modified starch, maltodextrin, cellulose, carboxymethyl cellulose, methylcellulose, hydroxypropyl methylcellulose, alginate, gelatin, or a combination thereof. Any one or more of the foregoing hydrocolloids may be excluded from the colored compositions disclosed herein.

[0051] Starches are available from a variety of botanical sources, and native and modified forms of starches are contemplated for use in food products. The starches can be natural, non-processed starches, physically processed starches, or derivatives thereof. In some aspects, the one or more starches are corn starch, tapioca starch, pea starch, rice starch, potato starch, wheat starch, or any combination(s) or derivative(s) thereof. In specific aspects, the one or more starches are corn starches or tapioca starches. Any one or more of the foregoing starches may be excluded from the colored compositions disclosed herein.

[0052] Maltodextrins are partially hydrolyzed forms of corn, rice, wheat, tapioca, or potato starches utilizing suitable acid and/or enzymatic hydrolysis. The maltodextrins are defined as having a Dextrose Equivalent (DE) of less or equal 20. Non-limiting examples of maltodextrins include the 5 DE, 6DE, 10 DE, 12DE, 15 DE, 16DE, 18 DE, and 19DE maltodextrins. DE characterizes average molecular weight of glucose oligomers by number. In practice, the maltodextrins have a distribution of glucose oligomers by molecular weight or DE value. Any one or more of the foregoing maltodextrins may be excluded from the colored compositions disclosed herein.

[0053] Non-limiting examples of gums include xanthan gum, gum Arabic, guar gum, locust bean gum, tara gum, larch gum, Konjac glucomannan, gum tragacanth, agar, carrageenan, pectin, gellan gum, or a combination thereof. In specific aspects, the one or more gums are gum Arabic. Any one or more of the foregoing gums may be excluded from the colored compositions disclosed herein.

[0054] In one aspect, a matrix of each particle in a first plurality of particles includes 30 wt. % to 50 wt. %, e.g., at least, at most, exactly, or between any two of 30, 32.5, 35, 37.5, 40, 42.5, 45, 47.5, and 50 wt. %, of one or more fast-dissolving high solubility food safe polymers, e.g., one or more monosaccharides, maltodextrins, or starches disclosed herein.

[0057] The colored compositions can comprise one, two, three, or more pluralities of particles, where the combination and/or concentration of the one or more food safe polymers, e.g., one or more hydrocolloids, of the particle matrix of one plurality of particles is different from the one or more food safe polymers, e.g., one or more hydrocolloids, of each of the other of the particle matrices of each of the other pluralities of particles, and where the different combinations and/or concentrations of the one or more food safe polymers, e.g., one or more hydrocolloids, results in each plurality of particles having a dissolution rate that is different from the dissolution rate of each of the other pluralities of particles. For example, in a colored composition including a first plurality of particles, a second plurality of particles, and a third plurality of particles, the solubility or dissolution rate of the one or more food safe polymers, e.g., one or more hydrocolloids, of the particle matrix of the first plurality of particles can be higher than the solubility or dissolution rate of the one or more food safe polymers, e.g., one or more hydrocolloids, of the particle matrix of the second plurality of particles and the particle matrix of the third plurality of particles, resulting in the first plurality of particles having a solubility or dissolution rate that is faster than the solubility or dissolution rate of the second plurality of particles and the third plurality of particles. Further, the solubility or dissolution rate of the one or more food safe polymers, e.g., one or more hydrocolloids, of the particle matrix of the third plurality of particles can be lower than the solubility or dissolution rate of the one or more food safe polymers, e.g., one or more hydrocolloids, of the particle matrix of the first plurality of particles and higher than the solubility or dissolution rate of the one or more food safe polymers, e.g., one or more hydrocolloids, of the particle matrix of the second plurality of particles, resulting in the third plurality of particles having a solubility or dissolution rate that is faster than the solubility or dissolution rate of the second plurality of particle but slower than the first plurality of particles.

In some aspects, the dissolution rate of the one or more food safe polymers, e.g., one or more hydrocolloids, of the second matrix is lower than the dissolution rate of the one or more food safe polymers, e.g., one or more hydrocolloids, of the first matrix and the one or more food safe polymers, e.g., one or more hydrocolloids, of the third matrix. In some aspects, the dissolution rate of the one or more food safe polymers, e.g., one or more hydrocolloids, of the third matrix is lower than the dissolution rate of the one or more food safe polymers, e.g., one or more hydrocolloids, of the first matrix and higher than the dissolution rate of the one or more food safe polymers, e.g., one or more hydrocolloids, of the second matrix.

[0059] The particle matrices can further include one or more sugars that dissolve in an aqueous environment, e.g., in water. The one or more sugars may be one or more monosaccharides, disaccharides, polysaccharides, other extracted carbohydrates, low molecular weight sugars or polyols, or a combination thereof.

In specific aspects, the one or more sugars are sucrose, dextrose, or trehalose. Any one or more of the foregoing sugars may be excluded from the colored compositions disclosed herein.

[0060] In one aspect, a matrix of each particle in a first plurality of particles includes 40 wt. % to 60 wt. %, e.g., at least, at most, exactly, or between any two of 40, 42.5, 45, 47.5, 50, 52.5, 55, 57.5, or 60 wt. %, of one or more sugars having a fast or moderate dissolution rate, e.g., one or more monosaccharides or disaccharides disclosed herein. In one aspect, a particle matrix includes 10 wt. % to 30 wt. %, e.g., at least, at most, exactly, or between any two of 10, 12.5, 15, 17.5, 20, 22.5, 25, 27.5, or 30 wt. %, of one or more slow-dissolving low solubility sugars, e.g., one or more polysaccharides disclosed herein. In one aspect, a particle matrix includes 1 wt. % to 20 wt. %, e.g., at least, at most, exactly, or between any two of 1, 2.5, 5, 7.5, 10, 12.5, 15, 17.5, or 20 wt. %, of one or more sugars having a fast or moderate dissolution rate, e.g., one or more monosaccharides or disaccharides disclosed herein. In one aspect, the combined wt. % of the one or more sugars in the particle matrix is 1-60 wt. %, e.g., at least, at most, exactly, or between any two of 1, 2.5, 5, 7.5, 10, 12.5, 15, 17.5, 20, 22.5, 25, 27.5, 30, 32.5, 35, 37.5, 40, 42.5, 45, 47.5, 50, 52.5, 55, 57.5, or 60 wt. %.

[0061] The colored compositions can comprise one, two, three, or more pluralities of particles, where the combination and/or concentration of the one or more sugars of the particle matrix of one plurality of particles is different from the one or more sugars of each of the other of the particle matrices of each of the other pluralities of particles, and where the different combinations and/or concentrations of the one or more sugars results in each plurality of particles having a dissolution rate that is different from the dissolution rate of each of the other pluralities of particles. For example, in a colored composition including a first plurality of particles, a second plurality of particles, and a third plurality of particles, the solubility or dissolution rate of the one or more sugars of the particle matrix of the first plurality of particles can be higher than the solubility or dissolution rate of the one or more sugars of the particle matrix of the second plurality of particles and the particle matrix of the third plurality of particles, resulting in the first plurality of particles having a dissolution rate that is faster than the dissolution rate of the second plurality of particles and the third plurality of particles. Further, the solubility or dissolution rate of the one or more sugars of the particle matrix of the third plurality of particles can be lower than the solubility or dissolution rate of the one or more sugars of the particle matrix of the first plurality of particles and higher than the solubility or dissolution rate of the one or more sugars of the particle matrix of the second plurality of particles, resulting in the third plurality of particles having a dissolution rate that is faster than the dissolution rate of the second plurality of particle but slower than the first plurality of particles.

[0062] Accordingly, in some aspects, the dissolution rate of the one or more sugars in the particle matrix of the first matrix is higher than the dissolution rate of the one or more sugars of the second matrix and the one or more sugars of the third matrix. In some aspects, the dissolution rate of the one or more sugars of the second matrix is lower than the dissolution rate of the one or more sugars of the first matrix and the sugars of the third matrix. In some aspects, the dissolution rate of the one or more sugars of the third matrix is lower than the dissolution rate of the sugars of the first matrix and higher than the dissolution rate of the one or more sugars of the second matrix.

[0063] The colored compositions can comprise one, two, three, or more pluralities of particles, where the combination and/or concentration of the one or more food safe polymers, e.g., one or more hydrocolloids, and/or the one or more sugars of the particle matrices can be selected or modified such that the particle matrix of one plurality of particles is different from the particle matrices of each of the other pluralities of particles, where the different combinations and/or concentrations of the one or more food safe polymers, e.g., one or more hydrocolloids, and/or the one or more sugars results in each plurality of particles having a dissolution rate that is different from the dissolution rate of each of the other pluralities of particles. Non-limiting examples of various food safe polymer and sugar combinations that can provide particle matrices having different dissolution rates include: one or more high solubility food safe polymers and one or more high solubility sugars; one or more low solubility food safe polymers and one or more low solubility sugars; one or more moderate solubility food safe polymers and one or more moderate solubility sugars; one or more high solubility food safe polymers and one or more low solubility sugars; one or more low solubility food safe polymers and one or more high solubility sugars; one or more moderate solubility food safe polymers and one or more low solubility sugars; one or more low solubility food safe polymers and one or more moderate solubility sugars; one or more high solubility food safe polymers and one or more moderate solubility sugars; and one or more moderate solubility food safe polymers and one or more high solubility sugars, where, in each of the foregoing examples, a high solubility material has a dissolution rate that is faster than the dissolution rate of a moderate solubility material and the dissolution rate of a low solubility material, and a low solubility material has a dissolution rate that is slower than the dissolution rate of a high solubility material and a moderate solubility material.

[0064] In each of the foregoing non-limiting examples, the concentration of the high, moderate, and low solubility food safe polymers and/or sugars can be adjusted as necessary to achieve a desired particle matrix solubility or dissolution rate, with typical particle matrices including 30-85 wt. %, e.g., at least, at most, exactly, or between any two of 30, 32.5, 35, 37.5, 40, 42.5, 45, 47.5, 50, 52.5, 55, 57.5, 60, 62.5, 65, 67.5, 70, 72.5, 75, 77.5, 80, 82.5, or 85 wt. %, or 0.1-60 wt. %, e.g., at least, at most, exactly, or between any two of 0.1, 1, 2.5, 5, 7.5, 10, 12.5, 15, 17.5, 20, 22.5, 25, 27.5, 30, 32.5, 35, 37.5, 40, 42.5, 45, 47.5, 50, 52.5, 55, 57.5, or 60 wt. % as the combined wt. % of the one or more food safe polymers, e.g., one or more hydrocolloids, and 1-60 wt. %, e.g., at least, at most, exactly, or between any two of 1, 2.5, 5, 7.5, 10, 12.5, 15, 17.5, 20, 22.5, 25, 27.5, 30, 32.5, 35, 37.5, 40, 42.5, 45, 47.5, 50, 52.5, 55, 57.5, or 60 wt. %, as the combined wt. % of the one or more sugars.

[0065] For example, the matrix of each particle in a plurality of particles can include 30 wt. % to 50 wt. %, e.g., at least, at most, exactly, or between any two of 30, 32.5, 35, 37.5, 40, 42.5, 45, 47.5, and 50 wt. %, of a fast-dissolving food safe polymer, and 40 wt. % to 60 wt. %, e.g., at least, at most, exactly, or between any two of 40, 42.5, 45, 47.5, 50, 52.5, 55, 57.5, or 60 wt. %, of a sugar having a moderate dissolution rate.

[0066] As a second example, a matrix of each particle in a plurality of particles can include 30 wt. % to 50 wt. %, e.g., at least, at most, exactly, or between any two of 30, 32.5, 35, 37.5, 40, 42.5, 45, 47.5, and 50 wt. %, of a food safe polymer having a moderate dissolution rate, 15 wt. % to 35 wt. %, e.g., at least, at most, exactly, or between any two of 15, 17.5, 20, 22.5, 25, 27.5, 30, 32.5, or 35 wt. %, of a slow-dissolving food safe polymer, and 10 wt. % to 30 wt. %, e.g., at least, at most, exactly, or between any two of 10, 12.5, 15, 17.5, 20, 22.5, 25, 27.5, or 30 wt. %, of a sugar having a moderate dissolution rate.

[0067] As a third example, the matrix of each particle in a plurality of particles can include 65 wt. % to 85 wt. %, e.g., at least, at most, exactly, or between any two of 65, 67.5, 70, 72.5, 75, 77.5, 80, 82.5, or 85 wt. %, of a food safe polymer having a moderate dissolution rate, and 1 wt. % to 20 wt. %, e.g., at least, at most, exactly, or between any two of 1, 2.5, 5, 7.5, 10, 12.5, 15, 17.5, or 20 wt. %, of a fast-dissolving sugar.

[0068] As a fourth example, the matrix of each particle in a plurality of particles can include 40 wt. % to 60 wt. %, e.g., at least, at most, exactly, or between any two of 40, 42.5, 45, 47.5, 50, 52.5, 55, 57.5, or 60 wt. %, of a slow-dissolving food safe polymer, 0.1 wt. % to 10 wt. %, e.g., at least, at most, exactly, or between any two of 0.1, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 wt. %, of a fast-dissolving food safe polymer, and 40 wt. % to 60 wt. %, e.g., at least, at most, exactly, or between any two of 40, 42.5, 45, 47.5, 50, 52.5, 55, 57.5, or 60 wt. %, of a fast-dissolving sugar.

[0069] In the foregoing examples, the dissolution rate of the plurality of particles of the first example would be higher than the dissolution rate of the plurality of particles in the second example and the dissolution rate of the plurality of particles in the third example, and the dissolution rate of the plurality of particles in the third example would be lower than the dissolution rate of the plurality of particles of the first example but higher than the dissolution rate of the plurality of particles of the second example. The dissolution rate of the plurality of particles in the fourth example would be lower than the dissolution rate of the plurality of particles of the first, second, and third examples.

B. Coloring Agents

[0070] Each particle in the plurality of particles disclosed herein further comprises a coloring agent. The coloring agent can be encapsulated by or uniformly dispersed in the matrix, and the coloring agent and the matrix are homogenous. In some aspects, the coloring agent is not comprised in a core within the matrix. Additionally or alternatively, in some aspects, the matrix and coloring agent are not layered together or with an additional matrix material. Additionally or alternatively, in some aspects, the matrix and/or coloring agent are not coated by an additional matrix material.

[0071] In some aspects, the coloring agent may be in the form of oil, aqueous solution, non-aqueous solution, or an emulsion and may be supplied as a liquid, powder, gel, or paste. The color of products can be important, as it can determine the overall consumer acceptability of the finished product. One of skill in the art would understand coloring properties to select the appropriate coloring agents for the food or beverage product.

[0072] In some aspects, the coloring agent can comprise one or more natural or artificial colorants. Non-limiting examples of natural colors include carotenoids, chlorophyllin, anthocyanins, betanin, annatto, caramel, carmine, elderberry, lycopene, paprika, turmeric/curcumin, genipen, or a combination thereof. Non-limiting examples of artificial colors include Ponceu 4R, carmoisine, erythrosine, allura red AC, citrus red 2, orange B, tartrazine, sunset yellow FCF, indigo carmine, indigotine, brilliant blue FCF, fast green FCF, lakes of any of the foregoing artificial colors, or any combination thereof. Any one or more of the foregoing colorants may be excluded from the colored compositions disclosed herein.

[0073] In one aspect, the combined wt. % of the one or more coloring agents in each particle in a plurality of particles is 0.001-20 wt. %, e.g., at least, at most, exactly, or between any two of 0.001, 0.002, 0.003, 0.004, 0.005, 0.006, 0.007, 0.008, 0.009, 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 wt. %. In some aspects, the particles include 0.1-10 wt. % of the one or more coloring agents. In some aspects, the particles include 5-15 wt. % of the one or more coloring agents. In some aspects, the particles include about 10 wt. % of the one or more coloring agents.

C. Additional Components

[0074] The particles in the pluralities of particles disclosed herein or the colored compositions including the pluralities of particles disclosed herein may further comprise one or more additional components. The one or more additional components may comprise one or more insoluble fibers, emulsifiers, anti-sticking or flow agents, plasticizers, or other minor processing aids as required. Sweeteners, food acids, salts, fragrances, diluents, fillers, preservatives, antioxidants, stabilizers, lubricants, and the like may also be employed herein if desired. Any one or more of the foregoing additional components may be excluded from the colored compositions disclosed herein. When present, the wt. % of each of the one or more additional components can be 0.1% to 20% by weight, e.g., at least, at most, exactly, or between any two of 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 wt. %.

[0075] In some aspects, the pluralities of particles disclosed herein may further comprise one or more insoluble fibers. Fibers can provide viscosity control for the melt in the extrusion process for producing the colored particulate materials and can provide product integrity during cutting, drying, cooling, and storage. The insoluble fibers may be natural and can include apple fiber, blueberry fiber, citrus fiber, sugarcane fiber, oat fiber, wood fiber, cellulose fiber, microcrystalline cellulose fiber, cotton fiber, rice fiber, wheat fiber, or mixtures thereof. In specific aspects, the insoluble fibers are sugarcane fibers. Any one or more of the foregoing insoluble fibers may be excluded from the colored compositions disclosed herein. When present, the combined wt. % of the one or more insoluble fibers in each particle in a plurality of particles can be 1-20 wt. %, e.g., at least, at most, exactly, or between any two of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 wt. %.

[0076] Non-limiting examples of emulsifiers include, e.g., dextrin, carrageenan, gelatin, egg protein, whey protein, lecithin, guar gum, xanthan gum, gum Arabic, carboxymethylcellulose, polysorbates, mono- and diglycerides, fatty acids from vegetable oil or animal fat, ammonium phosphatides, magnesium stearate, sorbitan monostearate, acetic acid esters, lactic acid esters, polyglycerol esters, propylene glycol esters, sucrose fatty acid esters, or a combination thereof. Emulsifiers can prevent the separation of components, which can improve the texture, shelf life, and quality of the colored particulate materials disclosed herein. One of skill in the art would understand these emulsifier properties to select the appropriate emulsifiers for the colored particles and colored particulate compositions. Any one or more of the foregoing emulsifiers may be excluded from the colored compositions disclosed herein.

[0077] Anti-sticking or flow agents can include magnesium, sodium, and potassium salts of fatty acids; silicon dioxide; titanium dioxide; calcium silicate; magnesium silicate; talc; sodium aluminum phosphate; calcium phosphate; magnesium carbonate; bentonite; sodium aluminosilicate; or combinations thereof. Anti-sticking or flow agents are powders with a low density that are spread thinly over the surface of particles or between them. They reduce the distance between particles, which reduces the Van der Waals forces of attraction and prevents particles from sticking together. They can also absorb moisture, which can prevent liquid bridges from forming on the surface of the particles. One of skill in the art would understand these properties and would select the appropriate anti-sticking or flow agents for the colored particles and colored particulate compositions. Any one or more of the foregoing anti-sticking or flow agents may be excluded from the colored compositions disclosed herein. When present, the combined wt. % of the anti-sticking agents can be 0.1% to 1% by weight, e.g., at least, at most, exactly, or between any two of 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, or 1 wt. %.

[0078] Plasticizers can include, e.g., water, ethanol, glycerin, propylene glycol, a carbohydrate solution, or mixtures thereof. Plasticizers can improve flexibility, prevent brittleness, improve durability, and prevent shrinking of food and beverage compositions. One of skill in the art would understand these plasticizer properties to select the appropriate plasticizer agents for the colored particles and colored particulate compositions. Any one or more of the foregoing plasticizers may be excluded from the colored compositions disclosed herein. In some aspects, no plasticizer is needed to obtain a desired plasticizing effect. For example, if the amount of water, contained in the particle matrix materials or the colored compositions is sufficient, no additional water or other plasticizer may be needed to be directly added to the composition during the mixing.

II. Methods of Making Colored Compositions

[0079] Reference is now made to FIG. 1, which is a simplified flowchart of a method 100 for producing the colored compositions including colored particulate materials having different solubilities or dissolution rates disclosed herein. The method 100 can be a melt extrusion process in which a coloring agent is encapsulated in a matrix to form the particles described herein.

[0080] In a first step 102, a matrix 104 including one or more food safe polymers, e.g., one or more hydrocolloids, and one or more sugars and a coloring agent 106 are mixed. Optionally, additional components described elsewhere herein may be mixed with the matrix and coloring agent. The individual components of the composition can be added either sequentially or at the same time, as long as all of the components are mixed and partially or completely melted prior to extrusion.

[0081] At step 108, the mixed matrix and coloring agent are conveyed to an extruder assembly, where the matrix is melted to form a viscous dispersion of the coloring agent, and the viscous dispersion is extruded through a die. The die can have multiple holes having or more shapes, e.g., spherical, nearly spherical, half-sphere, rod, cylindrical, football-shaped particles, star-shaped, heart-shaped, crescent moon-shape, flakes, disks, etc.

[0082] At step 110, the extruded material is cut to form the colored particulate material, i.e., a plurality of particles, each of which includes a coloring agent encapsulated in a matrix. For example, a rotating cutter knife can reduce strands of extruded material to particles. Depending on the linear speed of the extruded strands, rotating speed of the cutter, and the shape and size of the die holes, spherical, nearly spherical, half-sphere, rod, cylindrical, football-shaped particles, star-shaped, heart-shaped, crescent moon-shape, flakes, disks, etc. particles are formed. An illustration of an exemplary particle 200 produced according to method 100 is shown in FIG. 2, in which particle 200 comprises coloring agent 202 encapsulated by, i.e., uniformly dispersed, in matrix 204, where the coloring agent and the matrix are homogenous, the coloring agent is not comprised in a core within the matrix, the matrix and coloring agent are not layered together or with an additional matrix material, and the matrix and/or coloring agent are not coated by an additional matrix material.

[0083] At step 112, the colored particulate material may be dried using, e.g., conventional dries such as fluidized bed driers, and at step 114, the dried colored particulate material may be cooled, e.g., at ambient temperature.

[0084] At step 116, the colored particulate material may, after cutting, drying, or cooling, be mixed with another one or more colored particulate materials, each of the colored particulate materials having a color that is different than each of the other colored particulate materials In this way, a colored composition comprising two or more colored particulate materials, i.e., two or more separate colors, can be produced. An illustration of a colored composition 300 comprising two or more colored particulate materials produced according to method 100 is shown in FIG. 3, in which a first colored particulate material 302 is homogenously mixed with a second colored particulate material 304.

III. Color-Changing Products

[0085] A food or beverage product containing the colored compositions including colored particulate materials having different solubilities or dissolution rates disclosed herein is also described, including food or beverage products in which the colored particulate materials are topically applied and/or mixed into the food or beverage products. The food or beverage products can include, but are not limited to, a powder, a paste, a liquid, a solid, a semi-solid, a pure, a chew, or a candy. Non-limiting examples of food or beverage products include cereals, crackers, cereal bars, snack chips, doughs and frozen doughs, bakery products (e.g., bread and muffins), seasonings, ice cream, meat products, dairy products, sauces, dry beverage blends, chewing gum, gummies, hard candies, and the like.

[0086] When used in such food or beverage products, the total weight of the colored particulate materials, i.e., the combined weight of a first, second, third, or more plurality of colored particles, can be 0.1 to 10%, e.g., at least, at most, exactly, or between any two of 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 wt. %.

[0087] The food or beverage products optionally can include other ingredients in addition to the colored particulate materials to the extent that these optional ingredients are edible and do not adversely affect the activity of the colored particulate materials. For example, such optional ingredients should not impart an undesirable off-taste, off-color, off-odor, unpleasant mouthfeel, unpleasant smell, or gritty texture to the food or beverage.

[0088] In certain aspects, the food or beverage product containing the colored compositions including colored particulate materials having different solubilities or dissolution rates is a color changing food or beverage product. In some aspects, the combination and/or concentration of particle matrix components having different solubilities are selected or modified to provide differently colored particulate materials having different dissolution rates. Accordingly, some colored particulate materials having a high dissolution rate will dissolve faster in a food or beverage, while other colored particulate materials having a low dissolution rate will dissolve slower in a food or beverage. The first particulate materials to dissolve will provide a first color, while the second or subsequent particulate materials to dissolve will provide a second or subsequent colors.

[0089] For example, when colored particulate materials are dissolved in a food or beverage, dissolution of a first colored particulate material can provide a first color that predominates for a first time period T.sub.1. After completion of T.sub.1, dissolution of a second colored particulate material can change the color the food or beverage (over a transitional or delay time T.sub.2) to a second color that predominates for a third time period T.sub.3. Time period T.sub.3 may continue indefinitely (i.e., until the food or beverage is consumed) or may transition into additional colors if desired and if further colored particulate materials are included in the food or beverage product. For example, if a third color is desired, after T.sub.3, dissolution of a third colored particulate material can change the color the food or beverage (over a transitional or delay time T.sub.2) to a third color that predominates for a time period T.sub.5 until the food or beverage is consumed.

[0090] The number, nature, and duration of each sequential change in color as well as the length of the transitional periods can be modified as desired to achieve the desired organoleptic effect, but in some aspects, each of T.sub.1, T.sub.2, T.sub.3, T.sub.4, and T.sub.5 are between 0 seconds and 30 minutes.
