COLOR COMPOSITIONS AND METHODS OF MAKING COLOR COMPOSITIONS COMPRISING STARCH AS A MATRIX
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims priority to United States Provisional Application No.
61/630,779, filed December 19, 2011, which is incorporated herein by reference in its entirety.
BACKGROUND
[0002] Color compositions, such as those comprising non-toxic dyes, lakes and pigments, are in great demand for providing attractive colors to foods, cosmetics and pharmaceuticals, and are regulated by government agencies for such purposes. Colorants that may be recognized as safe at one time may later be deemed to be unsafe for ingestion or use in a cosmetic. As such, there always remains a need to provide new color compositions that are deemed safe for such uses. There also is a need for improved and more efficient processes to produce such color
compositions.
SUMMARY
[0003] This disclosure provides color compositions comprising a colorant and at least one starch. This disclosure also provides methods for making color compositions comprising heating a first dispersion comprising a first amount of a first starch to a temperature greater than about 60°C, and adding a colorant and a second amount of a second starch to the first dispersion to form a second dispersion, wherein the second amount of the second starch is added when the temperature of the dispersion is less than about 60°C. This disclosure also provides methods for preparing color compositions, comprising heating a first dispersion comprising a first starch to a temperature greater than about 60°C, and adding a colorant.

Any discussion of the references states what their authors assert, and the applicant reserves the right to challenge the accuracy and pertinency of any of the documents cited herein.
[0009] This disclosure generally provides color compositions and methods of making color compositions, where the compositions may be safely incorporated into foods, cosmetics, and pharmaceuticals. The color compositions may, for example, be used in lieu of color
compositions that may have been determined to be unsafe or may have become subject to restricted use under governmental regulations.
1. Color Compositions
[0010] The color compositions of this disclosure generally may include a colorant and a starch. The starch may act as a carrier. The color compositions also may include one or more additional additives including, but not limited to, non-starch carriers, dispersants, antioxidants, and pH modifiers. Each of the various components of the compositions may be food grade materials, such as those "generally recognized as safe" ("GRAS") by the United States Food and Drug Administration ("FDA"), and/or by other regulatory entities. In particular, food safe components may include those listed as approved under 21 C.F.R. §§ 73, 74, 172, 182 and 184.
[0011] The color compositions of this disclosure may have enhanced color stability. Color stability may be measured using a color stability test. For example, tristimulus values may be used to determine color stability. Tristimulus values represent the magnitude of three standard stimuli, i.e., hue, chroma (saturation), and lightness, required to match a given light sample. To facilitate accurate specification of object colors and color differences, in 1976, the Commission Internationale de l'clairage ("CIE") recommended three-dimensional uniform color spaces, CIELAB and CIELUV. In imaging applications, CIELAB space is commonly used.
[0012] In CIELAB space, L* indicates the lightness (e.g., a more negative L* value indicates that the sample has become darker; a more positive L* value indicates that the sample has become lighter), a* indicates reddishness (a*) to greenishness (-a*), and b* indicates yellowishness (b*) to blueishness (-b*) of a given color. The L*, a*, and b* parameters can be measured with, for example, a tristimulus colorimeter, such as, for example, a COLORQUEST® XE color measurement spectrophotometer (HunterLab, Reston, Virginia). The output of the colorimeter can provide a method of quantifying colorant stability, through the calculation of color difference, AE*at, of a sample at various time intervals. AE*ab values can be calculated according to the following formula:
AEa * b = Μ2 + (Δα* )2 + (Δδ* )2
[0013] A small AE*ab between the color measurements (e.g., less than 7) of a sample may suggest a stable colorant, whereas a large AE*ab between the color measurements (e.g., greater than 7) of a sample may suggest an unstable colorant. Typically, a AE*ab of less than about 1 is not detectable to the human eye.
[0014] Samples including a colorant can be tested for colorant stability by exposing the sample to a light source, for example, a Xenon lamp that emits a broad spectrum light, i.e., infrared, ultraviolet, and visible light (about 400 to about 765 W/m2; 0.0036 MJ/W-hr), in a light box and determining AE*ab for the sample.
[0015] Samples including a colorant can be tested for colorant stability by exposing the sample to a light source, for example, a Xenon lamp that emits a broad spectrum light, i.e., infrared, ultraviolet, and visible light (about 400 to about 765 W/m2; 0.0036 MJ/W-hr), in a light box, measuring a first refiectance colorimeter spectral curve of the sample at a first time, further exposing the sample to the light source, measuring a second reflectance colorimeter spectral curve of the sample at a time later than the first time, and determining the integrated space between the first and second reflectance colorimeter spectral curves representing the beginning and ending values for light absorbance in the spectrum region selected (e.g., 430 nm to 530 nm; basic blue spectrum). The spectral reflectance curves can be measured with, for example, a reflectance colorimeter, such as, for example, a COLORQUEST® XE color measurement spectrophotometer (HunterLab, Reston, Virginia). The difference between the two spectral reflectance curve regions can be described as: (s2)dx = A ≠ectaace ,
Figure imgf000005_0001
where si is the first reflectance colorimeter spectral curve, s2 is the is the second reflectance colorimeter spectral curve, and the difference is the area between the reflectance colorimeter spectral curves, si and s2, which represents the change in overall reflectance of the sample over time a. Colorants
[0016] Colorants suitable for the color compositions disclosed herein generally may be nontoxic colorants that are suitable for ingestion or use in a cosmetic. Colorants may include natural colorants and synthetic dyes and lakes approved for human consumption.

This includes embodiments where the amount of colorant (by weight) in the color composition ranges from about 3.00 wt% to about 30.00 wt%, including, but not limited to, amounts ranging from about 5.00 wt% to about 20.00 wt%, and from about 10.00 wt% to about 15 wt% of the total composition.
[0020] It should be understood that, as used herein, the term "about" is synonymous with the term "approximately." Illustratively, the use of the term "about" indicates that a value includes values slightly outside the cited values. Variation may be due to conditions such as experimental error, manufacturing tolerances, variations in equilibrium conditions, and the like. In some embodiments, the term "about" includes the cited value plus or minus 10%. In all cases, where the term "about" has been used to describe a value, it should be appreciated that this disclosure also supports the exact value,
b. Starches
[0021] The color compositions of this disclosure may include at least one starch. The starch may function as a stabilization matrix, and thus may act as a carrier. The starch may be an unmodified or a modified starch, depending on the desired reactivity and solubility of the starch. In some embodiments, the starch may be an unmodified starch, including, but not limited to, rice starch, potato starch, wheat starch, maize starch, tapioca starch, manioc starch, sago starch, taro starch, and/or any other unmodified starch that may be available for use in food, cosmetic or pharmaceutical applications.
[0022] The total amount of starch used in the color composition may be less than about 65.00 wt%, less than about 60.00 wt%, less than about 57.50, less than about 55.00 wt%, less than about 52.50 wt%, less than about 50.00 wt%, less than about 47.50 wt%, less than about 45.00 wt%, less than about 42.50 wt%, less than about 40.00 wt%, less than about 37.50 wt%, less than about 35.00 wt%, or less than about 32.50 wt% of the total composition. The total amount of starch may be greater than about 30.00 wt%, greater than about 32.50 wt%, greater than about 35.00 wt%, greater than about 37.50 wt%, greater than about 40.00 wt%, greater than about 42.50 wt%, greater than about 45.00 wt%, greater than about 47.50 wt%, greater than about 50.00 wt%, greater than about 52.50 wt%, greater than about 55.00 wt%, or greater than about 57.50 wt%. This includes embodiments where the amount of starch (by weight) in the color composition ranges from about 30.00 wt% to about 65.00 wt%, including, but not limited to, amounts ranging from about 40.00 wt% to about 55.00 wt%, and from about 45.00 wt% to about 55.00 wt% of the total composition.
[0023] As discussed in more detail below, the starch may be added during the preparation of the color composition all at once as one amount, or during multiple steps as two or more amounts. When the total amount of starch is added during multiple steps as two or more amounts during the preparation of the color composition, the first amount may be added to an aqueous reaction mixture that is heated to form a first dispersion, which is subsequently cooled. A second amount thereafter may be added when the temperature of the dispersion is lower than about 60°C to form a second dispersion. It should be appreciated that starch, particularly unmodified starch, may be difficult to solvate in water unless it is heated. As such, addition of starch at different temperatures, and/or in the presence of other additives, may lead to dispersions having different properties, which may be utilized to devise more efficient methods for making color compositions. This is discussed in more detail below with respect to the methods of making color compositions.
c. Additional Additives
[0024] As indicated above, the color compositions also may include one or more additional additives including, but not limited to, non-starch carriers, dispersants, antioxidants, and pH modifiers.
(1) Non-Starch Carriers
[0025] In addition to starch, one or more other non-starch carriers may be used as stabilization matrices for the colorants, and/or to affect the solubility of the color compositions (e.g., to solvate or emulsify oil soluble or water soluble colors). The carriers may be water soluble, partially water soluble, or water insoluble carriers, depending upon the intended use of the color composition. Suitable carriers may include, but are not limited to, carbohydrates (e.g., sugars, celluloses, etc.), lipids (e.g., oils, waxes, fats, stearates, and glycerides, etc.), peptides (e.g., gelatins and the like), and inorganic materials (e.g., salts, oxides, and hydrates, etc.). Some carrier materials may have their origin in plant or animal matter. Any food safe or food compliant non- starch carrier of natural origin may be used for these purposes.

(4) pH Modifiers
[0031] During manufacture of the color compositions disclosed herein, the pH of dispersions containing the colorant and carrier materials may, in some cases, be modified to improve the association of the colorant with the carrier materials, and/or to adjust and/or stabilize the color of the color compositions made from the dispersions. For example, some colorants may be pH sensitive, such that adjusting the pH with a pH modifier may change and/or stabilize the shade, hue, or intensity of the colorant. For example, anthocyanin may be red, blue or green at pH to 3, 8 and 10 respectively, and as such, color compositions containing anthocyanin may be made having different colors by adjusting the pH of dispersions containing the colorant prior to final processing of the color composition. Any food safe or food compliant pH modifiers may be used for these purposes.

The balance of the color compositions may be water.
2. Methods of Making Color Compositions
[0034] This disclosure also provides methods of making the color compositions disclosed herein. These methods generally comprise associating (e.g., encapsulating or otherwise binding) a natural color with a starch, which acts as a stabilization matrix. The color compositions generally may be made by forming, under controlled conditions, one or more dispersions comprising the starch and/or the natural colorant. The total amount of starch in a color composition may be added during the preparation of the color composition either all at once, or in multiple steps. As discussed above, these dispersions further may include one or more other non-starch carriers, dispersants, antioxidants, and pH modifiers.
[0035] Some methods of preparing the color composition comprise heating a first dispersion, which includes all of the starch for the color composition, to a temperature greater than about 60°C (e.g., greater than about 62.5°C, greater than about 65°C, greater than about 67.5°C, greater than about 70°C, greater than about 72.5°C, greater than about 75°C, greater than about 77.5°C, greater than about 80°C, greater than about 82.5°C, or greater than about 85°C). A colorant subsequently is added to the first dispersion to form a second dispersion. In some embodiments, the first and second dispersions may have between about 5 wt% and about 15 wt% starch. The first and second dispersions may have less than about 15 wt% starch, less than about 14 wt% starch, less than about 13 wt% starch, less than about 12 wt% starch, less than about 11 wt% starch, less than about 10 wt% starch, less than about 9 wt% starch, less than about 8 wt% starch, less than about 7 wt% starch, or less than about 6 wt% starch. The first and second dispersions may have greater than about 5 wt% starch, greater than about 6 wt% starch, greater than about 7 wt% starch, greater than about 8 wt% starch, greater than about 9 wt% starch, greater than about 10 wt% starch, greater than about 11 wt% starch, greater than about 12 wt% starch, greater than about 13 wt% starch, or greater than about 14 wt% starch. This includes embodiments where the first and second dispersions have starch amounts ranging from about 5 wt% to about 15 wt% starch, including but not limited to starch amounts ranging from about 6 wt% to about 14 wt% starch, and from about 8 wt% to about 12 wt% starch. In some embodiments, the first dispersion may be cooled to a temperature less than about 60°C (e.g., less than about 57.5°C, less than about 55°C, less than about 52.5°C, less than about 50°C, less than about 47.5°C, less than about 45°C, less than about 42.5°C, less than about 40°C, less than about 37.5°C, or less than about 35°C), such as to room temperature, prior to adding the colorant. Other ingredients, such as other non- starch carriers, dispersants, pH modifiers and/or antioxidants may be added to the first dispersion (either before or after cooling), and/or to the second dispersion. After all of the various components have been added, the resultant dispersion may be dried (e.g., via spray drying, filtration, or any other suitable process) to form the color composition.
[0036] Some methods for preparing the color compositions include heating a first dispersion comprising a first amount of starch to a temperature greater than about 60°C (e.g., greater than about 62.5°C, greater than about 65°C, greater than about 67.5°C, greater than about 70°C, greater than about 72.5°C, greater than about 75°C, greater than about 77.5°C, greater than about 80°C, greater than about 82.5°C, or greater than about 85°C), and adding a colorant and a second amount of a second starch to the first dispersion to form a second dispersion. The first and second starches may be the same or different. The second amount of the second starch may be added when the temperature of the dispersion is less than about 60°C (e.g., less than about 57.5°C, less than about 55°C, less than about 52.5°C, less than about 50°C, less than about 47.5°C, less than about 45°C, less than about 42.5°C, less than about 40°C, less than about 37.5°C, or less than about 35°C), such as at room temperature. The second dispersion may have more starch by weight than the first dispersion. For example, the first dispersion may have between about 5 wt% and about 15 wt% starch, and the second dispersion may have between about 15 wt% and about 30 wt% starch. The first dispersion may have less than about 15 wt% starch, less than about 14 wt% starch, less than about 13 wt% starch, less than about 12 wt% starch, less than about 11 wt% starch, less than about 10 wt% starch, less than about 9 wt% starch, less than about 8 wt% starch, less than about 7 wt% starch, or less than about 6 wt% starch. The first dispersion may have greater than about 5 wt% starch, greater than about 6 wt% starch, greater than about 7 wt% starch, greater than about 8 wt% starch, greater than about 9 wt% starch, greater than about 10 wt% starch, greater than about 11 wt% starch, greater than about 12 wt% starch, greater than about 13 wt% starch, or greater than about 14 wt% starch. This includes embodiments where the first dispersion has starch amounts ranging from about 5 wt% to about 15 wt% starch, including but not limited to starch amounts ranging from about 6 wt% to about 14 wt% starch, and from about 8 wt% to about 12 wt% starch. The second dispersion may have less than about 30 wt% starch, less than about 29 wt% starch, less than about 28 wt% starch, less than about 27 wt% starch, less than about 26 wt% starch, less than about 25 wt% starch, less than about 22.5 wt% starch, less than about 20 wt% starch, less than about 17.5 wt% starch, or less than about 16 wt% starch. The second dispersion may have greater than about 15 wt% starch, greater than about 16 wt% starch, greater than about 17 wt% starch, greater than about 18 wt% starch, greater than about 19 wt% starch, greater than about 20 wt% starch, greater than about 22.5 wt% starch, greater than about 25 wt% starch, greater than about 27.5 wt% starch, or greater than about 29 wt% starch. This includes embodiments where the second dispersion has starch amounts ranging from about 15 wt% to about 30 wt% starch, including but not limited to starch amounts ranging from about 18 wt% to about 28 wt% starch, and from about 20 wt% to about 25 wt% starch. The second amount of starch may be added before or after the colorant. Other ingredients, such as other non-starch carriers, dispersants, pH modifiers and/or antioxidants may be added to the first dispersion (either before or after cooling), and/or to the second dispersion.
[0037] In embodiments where a second amount of starch is added when the temperature of the dispersion is less than about 60°C, it has been observed that the viscosity of the dispersion decreases upon addition of the second amount of starch. This was true even under circumstances where the second dispersion comprises more starch by weight than the first dispersion. For example, it has been observed that, when the first dispersion comprises between about 5 wt% and about 15 wt% of starch, and a second amount of starch is added when the temperature of the dispersion is less than about 60°C to form a second dispersion comprising between about 15 wt% and about 25 wt% of starch, the viscosity of the second dispersion is noticeably less than the viscosity of the first dispersion. This was a surprising finding, because one skilled in the art would expect the viscosity of the dispersion to increase upon adding more starch. This finding allowed for the formation of dispersions having substantially greater solids content (i.e., substantially less water as a total percentage), which in turn allows for much faster and more efficient drying and subsequent processing of the color compositions.
[0038] After dispersions comprising the desired components are formed, the dispersions may be dried to form the color compositions disclosed above. Any suitable process may be used to dry the color compositions, including, but not limited to, spray drying, drum drying, freeze drying, supercritical drying, and the like. For example, the dispersions may be spray dried to lower the water content and thus produce color compositions having an amount of water less than about 15.0%, and more preferably less than about 5.0%. The dispersions may be at a temperature less than about 60°C (e.g., less than about 57.5°C, less than about 55°C, less than about 52.5°C, less than about 50°C, less than about 47.5°C, less than about 45°C, less than about 42.5°C, less than about 40°C, less than about 37.5°C, or less than about 35°C), such as at room temperature, before drying. The color compositions may stay true to shade after the water is substantially removed therefrom.
[0039] After drying, the color compositions may be milled according to known methods to impart plating qualities which allows the compositions to be use in dry mix applications.
