A process of controlling the production of enzymatic protein hydrolysate from cold water animals, containing up to 90% free amino acids, cold fish oil, hydroxilaptite (calcium orthophosphate), proteins, peptides, vitamin, minerals and calcium salts of phosphorus. The process provides a greater degree of refining than existing technology through the use of acid and alkaline denaturation steps, in combination with advanced separation and drying technology. The new drying technology results in a higher-quality, less expensive mixture than was previously possible.
