The project of "Research on Preparation of collagen oligopeptide for lowering blood pressure by aquacollagen" passed the acceptance

On July 13, the provincial science and technology Xinghai special project "Research on the preparation of blood pressure reducing collagen oligopeptide from aquatic collagen" undertaken by Fujian Fisheries Research Institute passed the acceptance The overall level of the project achievements is leading in China, which has a promoting effect on the development of comprehensive utilization of aquatic products in Fujian Province   In this project, the processes of degreasing, decolorizing and deashing of fish skin were optimized, and the production process of collagen oligopeptide with the effect of lowering blood pressure and blood lipid was studied by enzymatic hydrolysis of composite protease, and the pilot production was carried out; the production technical operation specifications of collagen oligopeptide with the effect of lowering blood pressure and blood lipid were formulated, and the prepared collagen oligopeptide of fish skin and fish scale was applied to ace in vitro The inhibition rate of (ACE) is more than 75%; the quality and safety indexes of the products are in line with the requirements of QB 2732-2005 for hydrolyzed collagen, and the components with molecular weight less than 2000 Da account for more than 75% According to the experiments of SHR, SD and WKY, fish skin collagen oligopeptide has the effect of lowering blood pressure and blood lipid, but it has no side effect on normal blood pressure   The project has great innovation in enzymatic separation of fish skin, fish scale and enzymatic debarkation, and has obtained two authorized invention patents The project has good social and economic benefits and wide application prospects.
