Aging-resistant steamed rice cakes served cold in summer and preparation method thereof

Abstract

The invention provides aging-resistant steamed rice cakes served cold in summer and a preparation method thereof. The preparation method comprises the following steps of performing soaking, performing pulping, performing boiling, performing thickening, performing pulp decoction, performing mold injection, performing cooling, performing inspection and performing temperature-varying storage. A composite aging-resistant agent used for the aging-resistant steamed rice cakes served cold in summer and the preparation method thereof disclosed by the invention can effectively restrain the aging of starch, so that the preservation quality of foods is improved, and the shelf life of the foods is prolonged; and an alpha-amylase soaking method is adopted for the technology of the aging-resistant steamed rice cakes served cold in summer, provided by the invention, and alpha-amylase can reduce the length of side chains of branched chain starch, so that recrystallization of the branched chain starch is restrained, and the aging of starch is delayed. According to the aging-resistant steamed rice cakes served cold in summer and the preparation method thereof disclosed by the invention, a temperature-changed storage method is adopted for the technology, the nucleation rate and the growth rate of crystals in the starch are in temperature-changed regulation, so that recrystallization of the branched chain starch is restrained, and the purpose of delaying the aging of the starch can be effectively achieved; and a constant-temperature heating and decocting method is adopted for the technology, so that compared with brewing type steamed rice cake powder served cold in summer, the aging-resistant steamed rice cakes served cold in summer have the advantages of being high in curing degree, high in glutinous degree, delicately fragrant in taste, transparent, clear, soft and refreshing.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to an anti-aging cold cake and a preparation method thereof. Background technique [0002] Cold cake is a traditional summer summer food in my country. It has the characteristics of soft and tender, refreshing taste and sweet aftertaste. It is a kind of snack in Sichuan, Guizhou, Jiangxi and other regions of my country. [0003] But at present, cold cakes are mostly handmade in workshops, the product quality is unstable, and the processing environment is difficult to guarantee, and the products have potential safety hazards. During the storage of cold cakes in summer, it is prone to aging in different degrees, and the edible quality is greatly reduced. Contents of the invention [0004] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide an anti-aging cold cake and a preparation method thereof. [0005] In ord...
