Composite Color-protecting Antioxidant Coating Liquid for Meat Products, Preparation Method and Application

Abstract

The invention discloses composite color-protecting antioxidant coating liquid for meat products, a preparation method and the application. And the raw materials include epigallocatechin gallate, yeast-β-glucan, ascorbic acid, chitosan and water. The preparation method is as follows: dissolve yeast-β-glucan in water, then add epigallocatechin gallate and ascorbic acid into the yeast-β-glucan solution and then add chitosan. And soak the cut meat in the composite color-protecting antioxidant coating liquid or spray the composite color-protecting antioxidant coating liquid on the surface of the meat, then drain it, and then package and store it in turn. According to the invention, EGCG, yeast-β-glucan and chitosan are compounded and scientifically matched, so that the fading degree of meat products is delayed, the color stability of the meat products during storage is enhanced, the color protection and oxidation resistance effects of the meat products are obviously improved, and the shelf life of the products is prolonged.
