Abstract(s)

Purpose of Review: This review explores the potential of fish by-products as a source of bioactive peptides for the food, pharmaceutical, and cosmetic industries. Focusing on their diverse bioactive and functional properties, it offers insights into their industrial utilization, contributing to a better understanding of their applications.Recent FindingsFish processing by-products, including wastewater and solid residues, serve as valuable sources of bioactive peptides exhibiting a remarkable range of biological activities, such as antioxidant, antimicrobial, and antihypertensive properties. These peptides exhibit a wide range of functional properties, such as solubility, water holding, fat binding, foaming, and emulsifying capacities. Moreover, they show significant potential for various industrial applications.SummaryBioactive peptides derived from fish by-products are attracting interest in multiple industries due to their diverse biological activities and functional properties. These peptides have emerged as a valuable and largely untapped resource, as they can be extracted from underutilized, or waste materials generated during fish processing operations.
