Problems solved by technology

[0005] In addition, the cold storage capacity of the conventional cold storage agent is relatively high, but the cooling capacity release process of the cold storage agent is relatively rapid, and the release time is short; the cooling capacity cannot be released slowly, which will affect the use effect of the cold storage agent and reduce the maintenance time of low temperature. Affect the quality and safety of cryopreserved products

Abstract

The invention relates to the technical field of agricultural biotechnology, in particular to a slow-release type composite cold storage agent. The composite cold storage agent comprises the followingcomponents: a temperature-controlled slow-release agent, calcium chloride, ammonium chloride, mannitol, polyvinyl alcohol, a thickener, sodium borate, a preservative and water, wherein the temperature-controlled slow-release agent is a special compound, has good adsorbability and water retention, becomes a gel-like product after absorbing water, and can play the role of component solidification and slow-release of clod energy in the cold storage agent; the thickener is selected from guar gum or xanthan gum; and the preservative is one or a mixture of any of potassium sorbate, sorbic acid, sodium benzoate and natamycin. The cold storage agent has the characteristics of large cold storage capacity, relatively high latent heat of phase change and relatively long cold release time, can be recycled, and is suitable for short-distance cold chain transportation of products such as vegetables, fruits, aquatic products, medicines and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural biotechnology, in particular to a slow-release composite cold storage agent. Background technique [0002] Cold storage agent is an energy storage substance composed of organic or inorganic compounds, generally in the form of translucent viscous gel, which can absorb and store a large amount of cold energy at low temperatures, and release a large amount of cold energy at high temperatures. Maintain a low temperature environment in and around a small area for a long time. The cold storage agent is mainly used as a cold storage filler in ice packs. Ice packs play a very important role in cold chain transportation. Almost all kinds of food that need to be kept cold and fresh, and food and medicines that need to be kept at low temperature, all need to use ice packs to keep the storage environment at a low temperature. State, to ensure the quality and safety of transported products. [0003] Ene...
