Cold chain coolant

Abstract

A cold chain coolant comprises, by weight, 2.5-7.5% of sodium chloride, 2.5-5% of sodium carboxymethyl cellulose, 2.5-7.5% of high fructose corn syrup, 0.1-3% of sodium alginate, 0.1-2% of sodium stearate, 2.5-5% of dietary fiber, and the balance of water. All the materials used herein are food-grade materials, the finished cold chain coolant is also of food grade, has the advantages of zero toxicity, harm and pollution, and is widely applicable to cold chain logistics, low temperature preservation, intelligent cold stations, clinical treatment and other fields, and secondary damage to foods or drugs during storage and transportation due to the cold chain coolant is avoided.

Description

technical field [0001] The invention relates to the technical field of logistics refrigeration, in particular to a food-grade, non-toxic, harmless and pollution-free cold chain storage agent. Background technique [0002] Cold storage technology uses physical, chemical, mechanical and other effective means to store cold energy in the cold chain storage agent, and release the stored cold energy when needed. The material produced by this technology, which can store cold energy efficiently and meet various physical and chemical requirements, is a cold chain storage agent. [0003] The cold chain storage agent is usually a viscous jelly mixture composed of organic or (and) inorganic compounds, which can absorb and store a large amount of cold energy at low temperatures, and release a large amount of cold energy when the temperature is high, which can be relatively stable. Maintain a low temperature environment in and around a small area for a long time. [0004] The main probl...

AI Technical Summary

Problems solved by technology

The common problem of the cold chain cold storage agent in the prior art is that a large amount of chemical raw materials are introduced to improve the various indicators of cold storage, and it cannot be absolutely non-toxic. Once leakage occurs during use, it will damage the transport or storage. Contamination of food and medicines, which can lead to serious consequences of poisoning of users or eaters

In order to ensure that the cold chain storage agent does not leak, it is necessary to use high-strength and thick packaging materials for the cold chain storage agent, which indirectly increases the use cost and supporting cost of the cold chain storage agent
