Title:
METHOD FOR PREPARING ACE INHIBITORY PEPTIDES FROM HAIRTAIL LEFTOVERS
Document Type and Number:
WIPO Patent Application WO/2014/194530
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for preparing ACE (Angiotensin-Converting Enzyme) inhibitory peptides from hairtail leftovers. The ACE inhibitory peptides are obtained by the steps of cleaning and mixing the hairtail leftovers with water, homogenization, enzymolysis and plate-and-frame filtration, intercepting small molecules of less than 3000 Da by ultrafiltration, and drying. Sephadex G-15 and RP-HPLC (Reverse Phase High-Performance Liquid Chromatography) can further be employed for two-step separation and purification to obtain high-purity ACE inhibitory peptides. The method of the present invention can change wastes into valuables by converting low-value hairtail leftovers into high-value ACE inhibitory peptides, achieve full use of resources, and has the advantages of easy process route, simplicity in operation, highly developed equipment used in the method, low investment cost and high recovery rate of the ACE inhibitory peptides.
