High-value development and utilization of functional peptides from seafood by-products and discards: A case study of antimicrobial peptides

Abstract

Antimicrobial peptides (AMPs) are a type of small protein that is part of the innate immune system and is widely distributed in marine organisms. Seafood by-products and discards are a good source of AMPs. The AMPs isolated and extracted from marine byproducts have been identified to possess various biological activities, including antibacterial, anticancer, immunomodulatory, and anti-inflammatory activities. This study provides a comprehensive overview of research progress on extracting AMPs from by-products and discards generated during seafood processing. It includes an analysis of different types of AMPs, reviews extraction methodologies, and evaluates current status alongside future perspectives for their application. By exploring the potential of AMPs derived from seafood by-products and discards, this review aimed to promote sustainable seafood utilization while addressing environmental concerns. In conclusion, the objective of this research is to provide support for the efficient management of seafood by-products and discards, leading to the production of value-added products.
