Abstract

The invention relates to a concentrated anti-freeze alga polypeptide liquid and a preparation method thereof, and belongs to the technical field of food processing. The concentrated anti-freeze alga polypeptide liquid is prepared from, by weight, 3-10 parts of concentrated anti-freeze laver liquid, 1-10 parts of marine polysaccharid, 0.2-0.5 part of phosphate and 30-100 parts of deionized water. New raw materials with a low cost are provided for anti-freeze polypeptide, and the extraction rate of anti-freeze polypeptide is increased to achieve industrialization and expand the application field.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a seaweed antifreeze polypeptide concentrate and a preparation method thereof. Background technique [0002] Antifreeze protein, also known as "ice structure protein", is a kind of active protein that attaches to the surface of ice crystals and inhibits the growth and recrystallization of ice crystals. Antifreeze protein can control the growth of ice crystals, reduce cell damage and maintain the original structure, texture and quality of products. [0003] At present, most of the research on antifreeze proteins is limited to deep-sea fish or other rare plants. Due to the high cost of raw materials, they can only stay in the laboratory research stage, and it is difficult to extract them for industrial application. [0004] According to relevant research, some people have transferred the antifreeze gene into bacteria to obtain antifreeze protein through transge...
