Abstract:
A method of applying a sprayable liquid coating onto an edible preformed solid substrate, which comprises:(a) forming a concentrated solution comprising from about 45 to about 75 wt. % of an edible polymer and from about 25 to about 55 wt. % of a solvent, and transferring said concentrated solution to a high pressure vessel; (b) chilling liquid carbon dioxide to a temperature of from about âˆ’20Â° C. to about 10Â° C.; (e) compressing said chilled carbon dioxide to a supercritical pressure of from about 1060 psi to about 5000 psi; (d) heating the supercritical carbon dioxide to a temperature of from about 31Â° C. to about 90Â° C.; (e) transferring the heated supercritical carbon dioxide to said high pressure vessel; (f) dissolving the heated supercritical carbon dioxide into said concentrated solution in said high pressure vessel in an amount sufficient to reduce the viscosity of the resulting solution to form a sprayable liquid coating composition, and (g) atomizing and spraying said sprayable liquid coating composition onto the surface of an edible preformed solid substrate such that, upon evaporation of said solvent and carbon dioxide from said sprayable liquid coating composition, the edible preformed solid substrate will have been coated with a solid edible surface coating.
