Abstract

A method of imparting pearlescence to a food product that includes applying a ready-to-use dispersion to a food product using confectionary panning, where the ready-to-use dispersion includes a pearlescent pigment, a cellulose derivative in an amount sufficient to enhance viscosity of the dispersion and impart a barrier coat to the food product, and a wax in an amount sufficient to impart a gloss to the food product. A method of incorporating a pearlescent pigment into a food product that includes applying a dispersion to a food product using panning, where the dispersion includes a pearlescent pigment, a viscosity enhancer, a fluid carrier, and a gloss agent.

Claims (39)

1. A method of imparting pearlescence to a food product, the method comprising:

applying a dispersion to a food product using confectionary panning without applying a subcoat to the food product, wherein the dispersion comprises food grade alcohol in an amount from about 50% to about 95% by weight of the dispersion, a pearlescent pigment, hydroxypropyl cellulose in an amount from about 6% to about 14% by weight of the dispersion, carnauba wax in an amount from about 2% to about 7% by weight of the dispersion, water from about 0% to about 10% by weight of the dispersion, ethyl acetate from about 2% to about 5% by weight of the dispersion, and a gum from about 0% to about 0.01% by weight of the dispersion.

2. The method of claim 1 , wherein the pearlescent pigment is present in an amount from about 1% to about 30% by weight of the dispersion.

3. The method of claim 1 , wherein the pearlescent pigment comprises a micaceous pearlescent pigment coated with titanium dioxide, iron oxide, and combinations thereof.

4. The method of claim 1 , wherein the dispersion comprises food grade alcohol in an amount from about 60% to about 90% by weight of the dispersion.

5. The method of claim 1 , wherein the confectionery panning requires only a single step.

6. The method of claim 1 , wherein the confectionary panning comprises hard shell panning.

7. The method of claim 1 , wherein the confectionary panning comprises soft shell panning.

8. The method of claim 1 , wherein the dispersion has a viscosity from about 250 centipoises to about 10,000 centipoises.

9. The method of claim 1 , wherein the dispersion dries in less than about 7 minutes.

10. The method of claim 1 , wherein the dispersion remains shelf stable for at least about 6 months.

11. A dispersion for imparting pearlescence to a food product comprising:

a food grade alcohol in an amount from about 50% to about 95% by weight of the dispersion,

a pearlescent pigment,

hydroxypropyl cellulose in an amount from about 6% to about 14% by weight of the dispersion,

carnauba wax in an amount from about 2% to about 7% by weight of the dispersion,

water from about 0% to about 10% by weight of the dispersion,

ethyl acetate from about 2% to about 5% by weight of the dispersion, and

a gum from about 0% to about 0.01% by weight of the dispersion,

wherein the dispersion does not contain a dextrin,

wherein the dispersion is ready-to-use for application to the food product in that no further preparation is needed prior to the dispersion being applied to the food product, no additional components need be added to the dispersion prior to the dispersion being applied to the food product, and no subcoat need be applied to the food product.

12. A method of incorporating a pearlescent pigment into a food product, the method comprising:

applying a dispersion to a food product using panning without applying a subcoat to the food product, wherein the dispersion comprises a food grade alcohol in an amount from about 50% to about 95% by weight of the dispersion, a pearlescent pigment, hydroxypropyl cellulose in an amount from about 6% to about 14% by weight of the dispersion, carnauba wax in an amount from about 2% to about 7% by weight of the dispersion, water from about 0% to about 10% by weight of the dispersion, ethyl acetate from about 2% to about 5% by weight of the dispersion, and a gum from about 0% to about 0.01% by weight of the dispersion.

13. The method of claim 12 , wherein the dispersion does not contain a shellac.

14. The method of claim 12 , wherein the method comprises applying the dispersion to a food product using confectionary panning.

15. The method of claim 12 , wherein the dispersion further comprises a preservative.

16. The method of claim 12 , wherein the dispersion further comprises stabilizers, thickeners, or combinations thereof.

17. The method of claim 15 , wherein the preservative comprises at least one of benzoates, parabens, sorbates, and combinations thereof.

18. A method of imparting pearlescence to a food product, the method comprising:

applying a dispersion to a food product using confectionary panning without applying a subcoat to the food product, wherein the dispersion comprises a food grade alcohol in an amount from about 60% to about 90% by weight of the dispersion, a pearlescent pigment in an amount from about 1% to about 30% by weight of the dispersion, hydroxypropyl cellulose in an amount from about 6% to about 14% by weight of the dispersion, carnauba wax in an amount from about 2% to about 7% by weight of the dispersion, water from about 0% to about 10% by weight of the dispersion, ethyl acetate from about 2% to about 5% by weight of the dispersion, and a gum from about 0% to about 0.01% by weight of the dispersion.

19. The method of claim 1 , wherein the dispersion does not contain a dextrin.

20. The method of claim 12 , wherein the dispersion does not contain a dextrin.

21. The method of claim 18 , wherein the dispersion does not contain a dextrin.

22. The method of claim 18 , wherein the dispersion does not contain a shellac.

23. The dispersion of claim 11 , wherein the dispersion does not contain a shellac.

24. The dispersion of claim 11 , wherein the gum is gellan gum.

25. The dispersion of claim 1 , wherein the gum is gellan gum.

26. The dispersion of claim 12 , wherein the gum is gellan gum.

27. The dispersion of claim 18 , wherein the gum is gellan gum.
