Abstract

The invention belongs to the field of scallop peptide and discloses a scallop peptide and a production method thereof. The production method of the scallop peptide comprises the steps that scallops are subjected to raw material pretreatment, a high-efficiency compound enzyme preparation is subjected to enzymolysis under the condition that the pH value is not adjusted and the temperature conditionis not controlled, insoluble and easy-moisture-absorption components are removed through filtering of an inorganic nanofiltration ceramic membrane, high-temperature and high-pressure treatment and concentration are conducted, and powder is prepared through drying. By adopting the method, the pH value of enzymolysis does not need to be adjusted, the enzymolysis temperature does not need to be controlled, the enzymolysis time is short, the application amount of an enzyme is low, the molecular weight of an enzymolysis product is low and centralized, prepared scallop peptide powder is good in secondary dissolubility in water, and moisture absorption and caking do not easily occur in the storage process.

Description

technical field [0001] The invention relates to the field of scallop peptide, in particular to a scallop peptide and a production method thereof. Background technique [0002] Scallop trim is a by-product produced during scallop processing, which has rich nutritional components and high utilization value. However, at present, these resources are usually discarded as production waste, and only a few are utilized, such as processed into fish and shrimp bait, soft canned food, fresh food, etc. Therefore, the research on scallop edges can not only realize the value reuse of by-products, but also provide people with rich nutritional products. [0003] CN106720914A discloses a preparation method of scallop edge polypeptide dry powder. The method comprises: drying and pulverizing the scallop edge, adding deionized water and alkaline protease, performing enzymolysis at a suitable temperature and pH value, and decomposing the scallop edge after complete enzymolysis. The enzyme is i...
