Fish waste Utilization with Reference to Fish Protein Hydrolysate – A Review

Abstract

Aquaculture and capture fisheries have contributed
to the global economy for decades, supporting
livelihood as well as nutritionall status. The sector
has been growing substantially that more than 60%
by-products as waste are generated which includes
skin, head, frames, fins and viscera. With an
increasing population with limited resource and
food supply, the need for utilizing the discarded
waste have added interest in many processing
industries. This review discusses on hydrolysis of
un-utilised fish and fish waste which are rich source
of nutrient that can impart stability in food
products, possess noble pharmaceuticals and
neutraceuticals significance to health. Fish protein
hydrolysate has attracted much attention as an
excellent source of bioactive peptides imparting
antioxidant, antihypertensive, immunomodulatory
and antimicrobial properties with a good balance of
essential amino acids. Above all, the review also
reveals the present status and future potential of
utilizing fish waste into economically and sustainable
products for human consumption.
