Angiotensin-I converting enzyme (ACE) Inhibitory and Antioxidant peptides from Seafood Processing Waste

Abstract

Bioactive peptides are oligopeptides that contain 2– 20 amino acid residues that can exhibit beneficial nutritional and physiological effects on human health. Protein hydrolysates or peptides derived from sea food processing waste with bioactive properties have been reported from different waste such as skin, fin, viscera, bone and air bladder. In vitro and controlled enzymatic hydrolysis of sea food processing waste using commercial enzymes as well as digestive proteases are the most employed for hydrolysis. The antihypertensive and antioxidant activities of bioactive peptides are influenced by several factors such as amino acid composition, hydrophobic amino acid residues, sequence and size. Most of the antihypertensive and antioxidant bioactive peptides from seafood have been investigated using in vitro and in vivo cell culture and animal models. This short review provides a comprehensive information of antihypertensive and antioxidant bioactive peptides from fish and fishery waste.
