Description

DETAILED DESCRIPTION OF THE INVENTION

[0022] The invention in its broader aspects relates to a method of forming a brown ingredient or additive comprising heating a browning ingredient source in the presence of a non-browning food-grade spacing agent for a time, and at a temperature which is effective to produce a high color intensity brown color in the absence of any added reactive sulfonium or ammonium compounds. The reaction conditions generally span pressure/temperature equivalents of −20 and 80 psi/245-350° Fahrenheit (116.3 to 176.7° C.), and within a defined pH band −0.5 and 2.5, to produce a dark brown low hue brown color. A representative composition for the brown color will include a browning ingredient in a weight percentage of 3 to 98%; a spacing agent in the weight concentration of 1 to 90%, and an acid concentration of 0.002% to 20.0%. The spacing agent concentration by weight can be up to—80%, or 70%, or 60%, or 50%, or 40%, or 30%, or 20%, or 10%. For each of the Class I-IV products described herein, the color can be dried into a powder with the same stability benefits and with an increase in the color per gram proportional to the removal of water.

[0023] Further disclosed is a brown color comprising a Class I caramel, burnt sugar or cooked plant juice in combination with a spacing agent wherein the spacing agent is a non-browning food grade composition that is stable at temperatures of 220 to 450° F. (104.4 to 232.2° C.), further wherein the caramel color, burnt sugar or cooked plant juice is produced with the spacing agent under the pressure/temperature equivalents of −20 and 5 psi/245 to 300° F. (118.3 to 148.9° C.) and within a pH band of −0.5 to 2.5, and further wherein the brown color ingredient is stable in acidic beverages with pH up to 7 and in another embodiment within the pH range of 0.25 to 2.7, beer and up to 30%, or from 10 to 20% weight/weight sodium, calcium or potassium chloride stable in the absence of added reactive sulfonium or ammonium compounds in the brown compositions. Salt stability would encompass systems containing as low as 1% sodium, calcium or potassium chloride in contact with the brown color ingredient, or between 1 and 5%, or between 1 and 10%, or between 10 and 15%, weight/weight of the salt. Typically a liquid Class I caramel color has a maximum color intensity of 0.080 with a solids content of 63%. This process allows for a liquid class I caramel color to be produced with color intensity of up to 0.600, or up to 0.450, or up to 0.350, or up to 0.250, or up to 0.150, or up to 0.100, with a solids content up to 80% by weight, or within a weight range of 20% to 80%. A representative composition for the brown color will include a browning ingredient in a weight percentage of 3 to 98%; a spacing agent in the weight concentration of 1 to 90%, and an acid concentration of 0.002% to 20.0%.

[0024] Further disclosed is a brown color comprising a Class IV caramel , wherein the caramel color is produced with the spacing agent wherein the spacing agent is a non-browning food grade composition that is stable at temperatures of 220 to 450° F. (104.4 to 232.2° C.) under typical class IV caramel color reaction parameters, and further wherein a greater color intensity, greater shelf-life stability and greater resinification stability caramel color can be produced. Typically a liquid Class IV caramel color has a maximum color intensity of 0.280 with a solids content of 53%. This process allows for a liquid Class IV caramel color to be produced with color intensity of up to 1.000, or up to 0.800, or up to 0.500, or up to 0.0400, or up to 0.350, or up to 0.300, with a solids content up to 80% by weight or within a weight range of 20% to 80%. Typically a liquid Class IV caramel color with a color intensity of 0.250 has a resinification time of 40 hours. This process allows for a liquid Class IV caramel color to be produced with resinification time of up to 400 hours, or up to 200 hours, or up to 100 hours, or up to 60 hours, with 0.250 color intensity. This process also allows for a liquid Class IV caramel color to be produced with resinification time of up to 350 hours, up to 180 hours, up to 80 hours, or up to 50 hours with a 0.300 color intensity. This process also allows for a liquid Class IV caramel color to be produced with resinification time of up to 300 hours, or up to 130 hours, or up to 50 hours, or up to 20 hours with a 0.400 color intensity.

[0025] Further disclosed is a brown color comprising a Class III caramel in combination with a spacing agent wherein the spacing agent is a non-browning food grade composition that is stable at temperatures of 220 to 450° F. (104.4 to 232.2° C.), further wherein the caramel color is produced with the spacing agent under typical class III caramel color reaction parameters, and further wherein a greater color intensity, storage stability and greater sodium, calcium or potassium chloride and beer stability caramel color can be produced. Typically a liquid Class III caramel color has a maximum color intensity of 0.220 with a solids content of 60%. This process allows for a liquid Class III caramel color to be produced with color intensity up to 0.500, or up to 0.400, or up to 0.350, or up to 0.250 with solids content of up to 80% by weight, or within a range of 20% to 80%.

[0026] Further disclosed is a brown color comprising a Class II caramel in combination with a spacing agent wherein the spacing agent is a non-browning food grade composition that is stable at temperatures of 220 to 450° F. (104.4 to 232.2° C.), further wherein the caramel color is produced with the spacing agent under typical class II caramel color reaction parameters, and further wherein a greater color intensity and greater shelf-life stability caramel color can be produced. Typically a liquid Class II caramel color has a maximum color intensity of 0.060 with a solids content of 65%. This process allows for a liquid Class II caramel color to be produced with color intensity of up to 0.600, or up to 0.300, or up to 0.200, or up to 0.150, or up to 0.100 with solids content of up to 80% by weight, or within a range of 20% to 80%.

[0027] The process for producing the particular brown colors incorporates a spacing agent component which does not react with the browning ingredients to produce brown color under the reaction conditions. The spacing agent can be selected from a range of materials which are food grade, are non-browning at reaction temperatures up to 450° F. (232.2° C.) and which are not susceptible to degradation under mild pressurization conditions of up to 80 psi. The concentration of the spacing agent in the reaction mixture is preferably 5-95% and most preferably 10-50%.

[0028] Acceptable spacing agents include polyols, plant juices, oligosaccharides, and certain oils and fats. Representative polyols include: glycerol, erythritol, mannitol, sorbitol (glucitol), arabitol, xylitol, lactitol, arabinitol, galactitol (dulcitol), ribitol, isomalt, and hydrogenated starch hydrolysates, and combinations of these polyols.

[0029] Representative plant juices include: pear, prune, peach, and cherry juice concentrates. These polyol sources contain both carbohydrates that can be browned and levels of spacing agent polyols, such as sorbitol. Polyol levels in these juices are typically between 5 and 90% of the juice solids, alternately between 5 and 50%, between 5 and 25%, between 5 and 13%, and between 6 and 8% juice solids.

[0030] Representative oligosaccharides are carbohydrate syrups with dextrose equivalence [DE] values between 15 and 70. In another embodiment the DE is between 40 and 60. Typically, the oligosaccharides consist of carbohydrates with a degree of polymerization greater than 3 and less than 1000. In another embodiment the degree of polymerization is greater than 4 and less than 100. Under the reaction conditions normally experienced in forming the caramel colors, the oligosaccharide compounds are hydrolyzed into smaller oligosaccharides during the cooking process, but will still act as a low reactivity medium and can continue to be introduced to the cooking system as that hydrolysis reaction continues. Representative oligosaccharides are: 18 DE maltodextrin, 36 DE corn syrup solids, 42 DE corn syrup solids, 43 DE corn syrup, and maltose syrups, and combinations of these oligosaccharides.

[0031] Another type of spacing agent is an edible grade oil or fat. The oils preferably are refined oils, and those with high smoke points. Most of the oils have smoke points between 390° F. and 465° F. (198.9 and 240.5° C.). Representative oils and fats include: maize, soybean, safflower, coconut, palm, canola, olive, castor, sesame, cottonseed, mustard, medium chain triglycerides, almond, apricot, avocado, grape seed, pumpkin, watermelon, bitter gourd, acai, black seed, borneo tallow nut, hemp oil, niger seed, fatty acids, pine nut, wheat germ, rice bran, cashew nut, hazel nut, walnut, perilla, pumpkin seed, chia seed, illipe butter, mango kernel, shea butter, and phospholipids, and combinations of these oils and fats. Animal derived fats and oils include beef tallow, butter fat, fish oil and lard, and combinations of these fats and oils.

[0032] The spacing agent incorporated into the reaction mixture when compared to reaction systems not containing spacing agent allows the caramelization reaction to continue for a longer period, thus encouraging the formation of darker color. As a result, the viscosity of the reaction mixture tends to be lower both because of the presence of the spacing agent and because of the controlled rate of polymerization of the sugar molecules. The spacing agent also allows reaction vapors and volatile byproducts to escape more readily, which allows for uniform reactant distribution during the reaction process.

[0033] The reaction system for preparing the brown color ingredient consists of a heated vessel (cooker) with typically coils of heated jacket or injected steam. The vessel is made from non-reactive materials such as stainless steel or glass lined vessels that have a mixing apparatus. The mixing apparatus is typically an impeller and typically has multiple pitched blade turbines to maximize axial mixing. Flat turbines can also be used to maximize radial mixing depending on where the heat source is located. The vessel has the capability to add and remove products and ingredients before, during and after the cook; and has the ability to add or remove pressure through vents and pumps before, during and after the cook.

EXAMPLES OF THE INVENTION

[0034] The following examples describe the process and the brown color composition in further detail.

[0035] The following examples are brown color formulations not containing a spacing agent. The reaction conditions and properties of the final color reaction product are also provided.

[0036] Into the reaction system described above, a comparative formulation was prepared using 50 lbs. (22.7 kg) high fructose corn syrup and 10 grams of hydrochloric acid.

[0037] The above reactants were heated to 300° F. (148.9° C.) at 0 psi in the above cooker for five hours once the syrup reached 300° F. (148.9° C.) and was then cooled by adding 5 lbs. (2.3 kg) of water over 10 minutes to the reaction.

[0038] The resulting product was deemed to have no usable brown color. The reaction product was turbid in water and had particles that settled to the bottom under 24 hour ambient temperature storage conditions. The absorbance at 610 nm of a 0.1 w/v solution was 0.465 but with a 700 nm absorbance value of 0.441. These data indicate a turbid solution with little color development. Black particles appeared to be suspended in the solution. These properties would not be acceptable to provide a uniform brown color for food or beverage products.

[0039] A second comparative example was prepared without spacing agent or acid. Into the cooker above was loaded 50 lbs. (22.7 kg) of high fructose corn syrup, which was heated to 300° F. (148.9° C.) at 0 psi, with a 5 hour cook time once the syrup reached 300° F. (148.9° C.). Cooling of the reaction product involving incorporation of 7 lbs. (3.2 kg) of water over 10 minutes to the cooker. The results of this comparative run provided a color intensity of the reaction product of 0.017 (Absorbance of a 0.1% weight/volume solution in deionized water through a 1 cm cuvette) with a hue index of 5.2 (10 times the log of ABS 510 nm/ABS 610 nm). Viscosity was 2500 cP. The color of this reaction product was too low for use as a brown color for food or beverage applications.

[0040] In a third comparative example, without acid or spacing agent, 50 lbs. (22.7 kg) of high fructose corn syrup was combined with 0.5 lbs. (0.23 kg) of sodium hydroxide and heated to 300° F. (148.9° C.) at 0 psi for 7 hours once the syrup reached 300° F. Cooling involved incorporation of 10 lbs. (4.5 kg) of water into the reaction mix. The result of this comparative run was that the color intensity of the reaction product was 0.057 with a hue index of 5.9 (10 times the log of ABS 510 nm/ABS 610 nm). The reaction product was unstable in 5-30% weight/weight sodium chloride solution. It was also unstable in an acidic medium below ph 3, developing haze and precipitation. The color was also not stable in beer. The product viscosity was 5000 cP at 20° C. This is an example of a typical Class I caramel cook and can be used in applications such as bakery and confection.

[0041] In a fourth comparative example, a typical class IV color run without a spacing agent, 37 lbs. (16.8 kg) of 80 DE glucose syrup was heated to 265° F. (129.4° C.) and 50 psi. Then 13 lb. (5.9 kg) of 70% ammonium bisulfite was injected over 2 hours and the reactants were heated to 265° F. (129.4° C.) at 50 psi for 2 hours. After 2 hours the mixture was cooled to below 180° F. (82.3° C.) with cool water in the cooling coils over 4 minutes. The result of this comparative run was that the color intensity of the reaction product was 0.223 with a hue index of 4.0 (10 times the log of ABS 510 nm/ABS 610 nm) and a resinification time of 25 hours.

[0042] In a fifth comparative example, a typical class III color run without a spacing agent, 50 lbs. (22.7 kg) of 80 DE glucose syrup was combined with 10 lb (4.5 kg) of 28% ammonium hydroxide and heated to 280° F. (132.8° C.) at 30 psi for 2 hours. Cooling involved running cool water through the thermal exchange coils in the vessel. The result of this comparative run was that the color intensity of the reaction product was 0.194 with a viscosity of 7000 cP at 20° C. This product was not stable in 5-30% weight/weight sodium, calcium or potassium chloride solutions or in beer.

[0043] In a sixth comparative example without a spacing agent, 50 lbs. (22.7 kg.) of 79 DE glucose syrup was combined with 4 lbs. (1.8 kg) of sodium hydroxide and 2 lb (0.91 kg) of sodium metabisulfite powder and heated to 300° F. (148.9° C.) at 0 psi for 3 hours once the syrup reached 300° F. (148.9° C.). Cooling involved incorporation of 10 lbs. (4.5 kg) of water into the reaction mix. The result of this comparative run was that the color intensity of the reaction product was 0.040 with a hue index of 5.5. The product viscosity was 2000 cP at 20° C. This is an example of a Class II caramel cook without a spacing agent.

The mixture was heated to 300° F. (148.9° C.) for 5 hours once the reactants reached 300° F. (148.9° C.), under atmospheric pressure conditions. Cooling of the reaction contents was with 5 lbs. (2.3 kg) water added to the cooker. The oil portion was decanted from the reaction product. The water soluble brown color was measured for color intensity and hue index. These results provided a color intensity of 0.061 with a hue index of 3.6 (10 times the log of ABS 510 nm/ABS 610 nm). Viscosity was 2800 cP at 20° C.

[0049] In inventive example 5, a typical class I with a spacing agent and acid, 10 lbs. (4.5 kg) of 42 DE corn syrup was combined with 50 lbs.

(4.5 kg) of 28% ammonium hydroxide, and heated to 280° F. (137.8° C.) at 30 psi for 2 hours once the reactants reached 280° F. (132.8° C.). Cooling involved running cool water through the thermal exchange coils in the vessel. The result of this inventive run was that the color intensity of the reaction product was 0.194 with a viscosity of 2000 cP at 20° C. This product is stable in 5-30% weight/weight sodium, calcium or potassium chloride solutions and in beer.

[0052] In inventive example 8, 40 lbs. of high fructose corn syrup was combined with 0.5 lbs. (0.23 kg) of sodium hydroxide and 10 lb (4.5 kg) of glycerol and heated to 300° F. (148.9° C.) at 0 psi for 7 hours once the syrup reached 300° F. (148.9° C.). Cooling involved incorporation of 10 lbs. (4.5 kg) of water into the reaction mix. The result of this comparative run was that the color intensity of the reaction product was 0.057 with a hue index of 5.9 (10 times the log of ABS 510 nm/ABS 610 nm). The reaction product was unstable in 15-30% weight/weight sodium chloride solution. It was also unstable in an acidic medium below pH 2.5, developing haze and precipitation. The color was not stable in beer. The product viscosity was 2000 cP at 20° C. This viscosity is lower than example This is an example of a Class I caramel cook with a spacing agent.

[0053] In inventive example 9, 40 lbs. (18.2 kg) of 79 DE glucose syrup was combined with 4 lbs. (1.8 kg) of sodium hydroxide, 2 lb (0.91 kg) of sodium metabisulfite powder and 10 lb (4.5 kg) of glycerol and heated to 300° F. (148.9° C.) at 0 psi for 3 hours once the syrup reached 300° F. (148.9° C.). Cooling involved incorporation of 10 lbs. (4.5 kg) of water into the reaction mix. The result of this comparative run was that the color intensity of the reaction product was 0.040 with a hue index of 5.5. The product viscosity was 1000 cP at 20° C. This is an example of a Class II caramel cook with a spacing agent.

[0054] In inventive example 10, without acid but with spacing agent, 40 lbs. (18.2 kg) of high fructose corn syrup was combined with 0.5 lbs. (0.23 kg) of sodium hydroxide and 20 lb. (9.1 kg) of sunflower oil and heated to 300° F. (148.9° C.) at 0 psi for 5 hours once the syrup reached 300 ° F. (148.9° C.). Cooling involved incorporation of 10 lbs. (4.5 kg) of water into the reaction mix. The oil portion was decanted from the reaction product. The water soluble brown color was measured for color intensity, viscosity and hue index. The result of this comparative run was that the color intensity of the reaction product was 0.057 with a hue index of 5.8 (10 times the log of ABS 510 nm/ABS 610 nm). The product viscosity was 3000 cP at 20° C. This is an example of a Class I caramel cook with a spacing agent. The use of the spacing agent in preparing the caramel color under any of the Class I-IV procedures allows for production of a product with a higher color intensity, and with lower hue index.
