Problems solved by technology

The common problem of the cold storage agent in the prior art is that a large amount of chemical raw materials are introduced to improve various indicators of cold storage, and it cannot be absolutely non-toxic. Once leakage occurs during use, it will damage the transported or stored food and Pollution caused by medicines, thereby causing serious consequences of poisoning of users or consumers
In order to ensure that the cooling agent does not leak, it is necessary to use high-strength and thick packaging materials for the cooling agent, which indirectly increases the use cost and supporting cost of the cooling agent

Abstract

The invention provides a cold storage agent. The cold storage agent is prepared from water, sodium chloride, sodium carboxymethylcellulose, sodium alginate, modified starch, red yeast rice powder and sodium stearate. The preparation method of the cold storage agent comprises the following steps: heating the water until the water is boiling; after cooling, filtering the water and descaling; heating the water again until the water is boiling; adding the sodium chloride; adding the sodium carboxymethylcellulose in batches while stirring to form a mixture in a mushy state; after naturally cooling the mixture to room temperature, adding the sodium alginate and the modified starch, and stirring evenly; adding the red yeast rice powder and the sodium stearate, and stirring evenly. The cold storage agent is food grade, non-toxic, harmless and non-polluting; the preparation method is simple, the raw materials are easy to obtain and the production cost is lower.

Description

technical field [0001] The invention relates to the technical field of cold storage, in particular to a food-grade, non-toxic, harmless and pollution-free cold storage agent and a preparation method thereof. Background technique [0002] Cold storage technology uses physical, chemical, mechanical and other effective means to store cold energy in the cold 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 called a cold storage agent. [0003] Coolant 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 at higher temperatures, which can be stored for a longer period of time. Maintain a low temperature environment in and around a small area. [0004] The main problem in the field...
