The invention discloses a process for improving the antioxidant capacity of puffer fish skin through fermentation and enzymolysis, and belongs to the technical field of marine biology. The present invention uses puffer fish skin as raw material, integrates modern biological separation technology, biological enzymatic hydrolysis technology, and mixed-bacteria microbial fermentation technology, and develops puffer fish skin polypeptide biological products with high in vitro antioxidant capacity, wherein the mixed-bacteria aerobic fermentation strain Mainly include Aspergillus niger and Bacillus subtilis. The obtained puffer fish skin polypeptide has strong antioxidant capacity, and the extract can be concentrated, adsorbed and dried, ethanolized or resin purified according to the application route, so as to meet the high-efficiency utilization in the fields of health care, food, and medicine. The process technology is simple and efficient, the obtained product has strong antioxidant capacity and free radical scavenging capacity, strong product stability, low production cost and easy industrial scale production. |
