Considerable amounts of fish processing by-products are discarded each year. About 30% this material may be skin and bone. Fish has more than 80% its total protein content as collagen. Furthermore, in recent years, there been a growing demand for collagen-based peptides due to their beneficial health effects. So, the objective present study was optimise obtaining bioactive hydrolysates from sal...

Actinopyga lecanora, a type of sea cucumber commonly known as stone fish with relatively high protein content, was explored as raw material for bioactive peptides production. Six proteolytic enzymes, namely alcalase, papain, pepsin, trypsin, bromelain and flavourzyme were used to hydrolyze A. lecanora at different times and their respective degrees of hydrolysis (DH) were calculated. Subsequent...

Chemical effluents generated by the isolation of fish gelatin and collagen hydrolysates produced from enzyme proteolysis skin wastes are protein-rich substrates that could be used as nutrients in bacterial bioprocessing. In this study, suitability such supporting growth a marine probiotic bacterium, Phaeobacter sp. DIFR 27-4, was studied. Both were obtained skins shark, tuna, salmon turbot. The...

During fish processing operations, such as skinning and filleting, the removal of collagen-containing materials can account for up to 30% of the total fish byproducts. Collagen is the main structural protein in skin, representing up to 70% of dry weight depending on the species, age and season. It has a wide range of applications including cosmetic, pharmaceutical, food industry, and medical. I...

Microalgal proteins are promising sources for functional nutrition and a sustainable candidate for nutraceutical formulations. They also gain importance due to emerging focus on a healthy nutrition and increase in the number of chronic diseases. In this study, dried dietary species of microalga, Chlorella vulgaris, and cyanobacterium Spirulina platensis were hydrolyzed with pancreatin enzyme to...

The whitefish industry generates a huge amount of rest raw material, which is currently wasted or underutilized in the production low-value products such as animal feed. While fish muscle primary product use for human consumption, material has great potential source protein and bioactive peptides food ingredients nutraceuticals. Enzymatic hydrolysis biotechnological processing method that can b...

Bioactivities of bulk fish protein hydrolysates (FPH) from defatted salmon backbones obtained with eight different commercial enzymes and their combinations were tested. All FPH showed antioxidative activity in vitro. DPPH scavenging activity increased, while iron chelating ability decreased with increasing time of hydrolysis. All FPH showed ACE inhibiting effect which depended on type of enzym...
