Abstract

The invention discloses a method for improving the oxidation resistance of abalone biological products, and belongs to the technical field of marine organisms. An abalone polypeptide biological product with high in-vitro oxidation resistance is developed by taking abalone protein as a raw material and integrating a modern biological separation technology, a biological enzymolysis technology and amixed bacteria microbial fermentation technology, and mixed bacteria aerobic fermentation strains mainly comprise candida utilis and bacillus subtilis. The obtained abalone polypeptide has strong oxidation resistance capacity, the extracting solution can be subjected to concentration, adsorption drying, alcohol precipitation or resin purification and other treatment according to application ways,and efficient utilization in the fields of health care, foods, medicine and the like is met. The process technology is simple and efficient, and the obtained product is high in oxidation resistance and free radical scavenging capacity, high in stability, low in production cost and easy for industrial large-scale production.

Description

technical field [0001] The invention relates to a method for improving the antioxidant capacity of abalone biological products, in particular to an abalone polypeptide biological product with high antioxidant capacity prepared by collaborative fermentation of microorganisms, belonging to the technical field of marine biology. Background technique [0002] Abalone, known as flatfish in ancient times, also known as mirror fish, nine-hole snail, bright eye fish, general cap, is a kind of marine mollusk, which belongs to the single-shelled marine shellfish of the gastropod family Abalone, and is also a traditional Chinese food. , known as flatfish in ancient times, is one of the delicacies of mountains and seas. It is known as "one bite of abalone, one bite of gold". "Diet Therapy Materia Medica" records that abalone enters the liver to clear blood stasis, enters the intestines to cleanse dirt, and does not hurt vitality. Strengthening yang, giving birth to a hundred pulses, ma...
