Marine fish and bioactive peptides in the cosmeceutical industries

Although fisheries production has increased dramatically over the last decades, the waste portion (such as skin, bones, intestines, and viscera) accounts for a significant part of yield. Marine fish are known as a rich source of bioactive compounds such as bioactive peptides. Recently, marine fish-derived peptides have obtained especial interest. The market size of fish protein hydrolysates is expected to grow of 4.5% between 2020 and 2026. Extraction of bioactive peptides is done by acid-alkaline hydrolysis, enzymatic hydrolysis and fermentation and depending on the structure and sequence of amino acids obtained, they have suitable biological properties suitable for the cosmetic-pharmaceutical industry. Furthermore, the production of marine bioactive peptides not only reduces environmental problems but also generates added value. The present article reviews the enzymatic hydrolysis and evaluated antimicrobial, antioxidant and anti-photoaging effects of peptides extracted from marine fish.
