Abstract

The fish processing industry generates up to 60% waste from processed fish. Instead of contributing to environmental pollution and facing challenges related to waste disposal, these by-products are utilized for the production of animal feed, fishmeal, fish oil, fish silage, fertilizers, and sauces. Additionally, hydrolysates are used in the production of high value-added products such as bioactive peptides, gelatin, and collagen. Studies on protein hydrolysates particularly focus on efficiently utilizing components derived from fish waste to realize their full industrial potential. This study reviews recent research on the functional properties of hydrolysates obtained from fish by-products and evaluates the current state as well as potential future directions in their application and research for effective utilization.
