Bioactive Peptides Derived from Fish By-Product Collagen

Abstract

The mismanagement of the fish processing industry has led to a lot of waste generation around the world, which contains a large amount of organic compounds. This massive amount of by-products is a major problem for both manufacturers and the environment. The exploitation of these by-products to produce functional biomolecule has become an essential demand. One of these biomolecules are collagen bioactive peptides derived from by-products. Many biological activities of peptides have been studied so far including antioxidant, antimicrobial, antihypertensive, anti-inflammatory, dipeptidyl-peptidase IV DPP-IV inhibitory, and etc. This study focuses on the main sources of collagen in fish by-products, the production of bioactive peptides from this collagen, and some biological activities of them.
