Fish protein hydrolysates obtained from fish-processing wastes can be used to make valuable ingredients for the food and healthcare industries. Hydrolysates are produced from fish muscle and viscera through an autolytic process by endogenous enzymes or an accelerated method using
Protein hydrolysates can be produced by acid, base or enzymatic hydrolysis processes. Acid hydrolysis produces salt that makes the product unsuitable for food and destroys some essential amino acids. An optimum process for one fish or shellfish by-product may not
Key molecules found in animal byproduct hydrolysates show potential for use as functional ingredients in aquaculture feeds. Animal co-product hydrolysates from slaughterhouse waste and rendered animal byproducts present a protein alternative.
Fish protein hydrolysates are naturally rich in nutrients that can help support aquatic species’ immune defenses in resisting stressors.
