Abstract

The invention discloses a method for preparing a biogenic biphase coating anti-staling agent for pickle stem tuber raw materials. The method comprises the following steps of: preparing an ethanol-water solution, regulating the pH value to be 6.1-6.6, and adding chitosan, propolis and porous starch into the ethanol-water solution based on the mass of the ethanol-water solution; adding natamycin, nisin and poly-L-lysine; and stirring by using an electric stirrer at constant temperature for 1 to 2 hours at a stirring rate of 900r / min, adding cinnamon oil, clove oil and rosemary oil, adding 1.0 to 3.0 percent of Tween-80 emulsifier, stirring by using the electric stirrer for 1 to 2 hours at a stirring rate of 1,200r / min to make the mixed oil uniformly dispersed, and homogenizing at a rate of 1.6*10<4>-2.0*10<4>r / min for 30 minutes to obtain the coating anti-staling agent. Product pollution because mixed bacteria are attached to the raw materials in the fermentation process is avoided, themature periods of pickle products are consistent, and product quality is stable.

Description

technical field [0001] The invention relates to a preparation method of a biological source dual-phase film preservative for pickles and tubers, and belongs to the technical field of food preservation. Background technique [0002] Kimchi is a traditional food in my country, and it is an indispensable ingredient of Sichuan cuisine. It has been deeply loved by consumers. With the development of the modernization process of the food industry, pickles have also entered industrialization. But the fresh-keeping problem of pickle raw material in transportation and storage process has not been solved. At present, there are many antistaling agents for agricultural products, but there is no biological antistaling agent dedicated to pickles and tubers. Contents of the invention [0003] Provided is a preparation method of a biological source two-phase film preservative for pickles and tubers. It does not cause damage to raw materials such as pickles and tubers and has a good fresh...
