The present invention relates to the use of turbine mixing during enzymatic hydrolysis of aquatic protein from species such as fish, aquatic mammals, crustaceans and/or mollusks, to obtain high quality aquatic protein hydrolysates, having very low oxidation, improved organoleptic profile and improved biological activity of interest, for human consumption and cosmetics. The turbine mixing can inhibit oxidation during hydrolysis, contribute to an increase in the bio-activity and decrease the bitter taste of the final product. The process can vary in starting material, pre-treatment, type and amount of enzyme, hydrolysis conditions, time, degree of hydrolysis and post-treatment. 1. A process for producing an aquatic protein hydrolysate with enzyme hydrolysis , comprising:a) subjecting a protein source material, water and an enzyme to turbine mixing to obtain enzymatic hydrolysis of the protein material;b) stopping the enzymatic hydrolysis by deactivating the enzyme under turbine mixing; andc) separating the obtained hydrolyzed aquatic peptide fraction from solid material.2. The process of claim 1 , wherein the turbine mixing takes place in a turbine mixing system incorporated into the reactor from the side or the top and can be fully or partially submerged in the reaction mass.3. The process of claim 1 , wherein the enzyme is selected from proteases from bacterial claim 1 , fungal or marine species.4BacillusBacillus licheniformis. The process of claim 3 , wherein the proteases are endo or exo proteases from strains claim 3 , Subtilisin claim 3 , including Subtilisin from such as Alcalase® claim 3 , Protamex® claim 3 , Flavourzyme® claim 3 , Neutrase® claim 3 , Protease A “Amano” claim 3 , Pescalase® claim 3 , Fromase™ Promod31™ or Maxatase™ or mixtures thereof.5. The process of claim 1 , wherein the protein source material is selected from material from fish claim 1 , including fish muscle claim 1 , fish skin claim 1 , fish viscera claim 1 , fish bones claim 1 , fish ...
