Unit 8 - Fish Protein Hydrolysate

8.1. Fish protein hydrolysates
Hydrolysis
Hydrolysis means breaking the chemical bond with the help of water molecules.
Protein hydrolysis
Protein hydrolysis refers to breaking the peptide bond and adding a water molecule with the help of acid/alkali under the supplied heat or breaking the peptides bond using the biological catalysts called enzymes. In this reaction one hydrogen ion added to the amino group involved in the broken peptide bond and hydroxyl ions added to the carboxylic group.
Protein hydrolysates
A mixture of amino acids and peptides obtained after hydrolysis of a protein
