Special composite preservative for walnut cake and application thereof

Abstract

The invention belongs to the field of food freshness keeping, and particularly relates to a special composite preservative for walnut cake. The special composite preservative comprises antioxidant of bamboo leaves, tea polyphenol, water-soluble chitosan, modified starch, food gum, functional sweeteners, an emulsifying agent, a chelating agent, natamycin and a rosemary extract. The application method comprises the steps that the walnut preprocessed by the preservative prepared by a component A is used as the walnut raw material of the walnut cake, a component B is fully mixed with revived powder of the walnut cake and then stewed into cake, 0.5 to 1% of alcohol by mass percentage in a component C is sprayed on the surface of the walnut cake after the sewing or before slicing or packaging, and then the walnut cake is stored for 60 days at natural room temperature. Compared with a reference substance, Hechuan walnut cake has the advantages that more than 85% of peroxide value is reduced, more than 85% of acid value is reduced, more than 90% of total clump count is reduced, and less than 15% of water loss ratio is achieved.

Description

technical field [0001] The invention belongs to the field of food preservation, in particular to a preservation process of peach slices.

AI Technical Summary

Problems solved by technology

[0004] As a typical representative of peach slices, “Hechuan peach slices” have the following problems in the process of production, sales, transportation and storage: ① Since the transportation of walnuts with shells takes up the volume, the shelled walnut kernels are purchased directly, and the walnut kernels in the peach kernels The oil content is heavy, and it is easy to oxidize under high temperature and high humidity conditions, resulting in grease change and mildew, so it can only be stored in a cold storage

④ Most of the raw materials of "Hechuan Taopian" are glutinous rice, and starchy products have the problem of starch aging (regrowth)
