Abstract

The invention discloses a brown beech mushroom refrigeration cold-insulation agent and a preparation method thereof, wherein the cold-insulation agent is formed by combining a thickening agent formed from soluble chitosan and soluble starch with a cooling capacity reinforcing agent formed from ethanol and glycerol by adding auxiliaries formed from soluble amine or amine salt and soluble acetate and water. The brown beech mushroom refrigeration cold-insulation agent disclosed by the invention is not iced at low temperature; the limited space of a packaging box can be effectively utilized; the transportation cost is reduced; a better effect is played in a long time; good flowability is still kept at minus 30 DEG C; due to addition of the auxiliaries, the cooling capacity storage amount is further increased; the cold-insulation agent disclosed by the invention is low in use amount and also has the advantages of being low in corrosivity and environmental influence; and in addition, if packaging is leaked, effective components of the cold-insulation agent have good effects on fresh keeping and growth of products.

Description

technical field [0001] The invention relates to the field of refrigerated antistaling agents for high-grade fresh products, in particular to a refrigerated antistaling agent and a preparation method thereof. Background technique [0002] The nutritional content of matsutake is extremely high. According to the information: every 100 grams of matsutake fresh products contains 2 grams of protein, 0.5 grams of fat, 20.17 mg of vitamin B, and 0.01 mg of vitamin C. It also contains cellulose, various amino acids, unsaturated fatty acids, and less in other fungi. Some - gluconic acid, nucleic acid derivatives, peptides and other substances, and also contain unique plant hormones that are beneficial to the human body. Therefore, matsutake has rich nutritional value. [0003] Matsutake is a rare edible fungus with high medicinal value. In Europe and Japan, matsutake was regarded as a mountain treasure in ancient times. The Japanese people especially loved it. It was a treasure that...
