Abstract

The invention relates to a freshness-retaining cold storage agent for vegetables and a preparation method thereof and belongs to the technical field of preservatives. The freshness-retaining cold storage agent is composed of borax, polyvinyl alcohol, pepper spray, silicone oil, alcohol, water, citric acid, sodium bisulfate, starch, silica gel, sucrose, sodium lactate, carboxymethyl chitosan, bamboo leaf powder and walnut leaf powder. According to the freshness-retaining cold storage agent, the cold storage time is further prolonged based on original design advantages, the time can be prolonged by about 5 hours, and the material use cost is very low.

Description

[0001] Technical field: [0002] The invention relates to a fresh-keeping cold storage agent for vegetables and a preparation method thereof, belonging to the technical field of fresh-keeping agents. [0003] Background technique: [0004] The main problem in the logistics and preservation of vegetables is that the cold chain is prone to breakage when they go through the wholesale market and finally enter the retail link. The special cold storage agent for vegetable product logistics is mainly aimed at the problems encountered in the short-distance transportation from the pre-cooling of the production area to the transport vehicle and from the wholesale market to the retailer. continuity, maximize the freshness of vegetable products, and increase added value. The existing low-temperature logistics basically adopts the refrigeration unit mode of refrigerated trucks, which consumes a lot of energy. [0005] According to statistics, the fuel consumption of the refrigerating unit...
