Functional and Bioactive Properties of Peptides Derived from Marine Side Streams

“…There are several studies in the available literature describing the different bioactive peptides obtained from sea rotifers, cod backbones, tilapia protein, congerel, sardina, tuna and shark muscle, squid by-products, shrimp shell waste, skate ( Okamejei kenojei ) gelatin, tuna heads and bones, Atlantic salmon skin, bone and muscles, skin gelatin of seabass, unicorn leatherjacket, Alaska pollock skin collagen and salmon skin collagen, among other marine side streams [ 20 , 21 , 22 , 27 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 ]. The profile and amount of bioactive peptides and their subsequent biological activity depend on the matrix.…”

“…There is increasing interest in several bioactive peptides with documented bioactivity [ 4 ] and, as a result, the use of these substances as nutraceuticals and functional foods in health is increasingly growing and widespread [ 19 ]. For instance, at this moment, on the market there are peptides obtained from the enzymatic hydrolysis of proteins assisted by the enzymes alkalase, trypsin and chymotrypsin [ 20 ], although there is still a limited exploitation of the application of peptides in food [ 6 , 21 , 22 ]…”

“…There is increasing interest in several bioactive peptides with documented bioactivity [4] and, as a result, the use of these substances as nutraceuticals and functional foods in health is increasingly growing and widespread [19]. For instance, at this moment, on the market there are peptides obtained from the enzymatic hydrolysis of proteins assisted by the enzymes alkalase, trypsin and chymotrypsin [20], although there is still a limited exploitation of the application of peptides in food [6,21,22] Therefore, taking into account the great potential for the commercial exploitation of fish side stream biomass-based proteins and their hydrolyzed forms, the objective of this study is to review the available methods for the recovery of peptides from fish by-products, their functional properties and bioactivity and the existing sources, as well as the potential applications of these bioactive compounds. In Figure 1, an overview of the main sources of seafood-derived bioactive peptides, their properties and major applications is presented.…”

Antibacterial activity of functional bioactive peptides derived from fish protein hydrolysate

“…According to Petrova et al [6], FPH is a product made from fish by-products using a protein hydrolysis method, which involves the breakdown of protein into a minor part of peptide and then into amino acid. Compared to raw protein, the protein hydrolysate produced contained peptides and amino acids that were easily absorbed [7]. Several methods have been used to extract proteins and peptides from fish byproducts, including acidic or alkaline hydrolysis, bacterial fermentation, and enzymatic hydrolysis.…”
