Abstract

The invention discloses the application of Bacillus subtilis subsp.natto ACE-IP and Bacillus subtilis subsp.natto ACE-IP in the preparation of ACE-inhibiting peptides from fermented scallop skirts, and its preservation number is CCTCC NO: M 2018081. The screening and identification method of Bacillus subtilis natto subspecies ACE‑IP includes: raw material processing and amino acid composition analysis; preparation of scallop skirt fermentation medium; primary screening of Bacillus natto; secondary screening of Bacillus natto; identification of strains . The Bacillus natto screened by the present invention is prepared by fermenting the scallop skirt to obtain the ACE inhibitory peptide, which fully exerts the effect of producing various proteases during the fermentation of the scallop skirt, and decomposes the scallop skirt macromolecular protein into small molecule ACE Inhibiting peptides with high inhibitory activity; not only provide excellent strains for industrial production of ACE inhibitory peptides that are safe, have no side effects and have high activity, but also provide a theoretical basis for the development, utilization and further processing of scallop skirts.

Description

technical field

[0001] The invention relates to the field of functional food processing, in particular to a strain of natto bacteria and its application in preparing ACE inhibitory peptides from fermented clam scallop skirt. Background technique

[0002] Chlamysfarreri belongs to the order Pterioida, Pteriina, Pectinidae, and the genus Chlamys. It is widely distributed in the coastal areas of northern China, such as Lvda in Liaoning and Shandong. Qingdao, Changdao, Rongcheng, Rizhao and other places. The scallop skirt is the remaining part after removing the scallop shell, which accounts for about 30% of the whole scallop. The output of Shandong Province alone is as high as 300,000 tons per year, but it is directly discarded due to seasonal restrictions in the production process. Reasonable and effective application has caused waste of resources and pollution of the environment. Studies have shown that scallop skirt contains a lot of protein, fat, carbohydrates and other n...
