A method of production of enzymatic protein hydrolysate from cold water animals that takes place under continuous mixing and precisely controlled conditions until amino acids and very short peptides are produced. The enzymatic protein hydrolysate of the present invention is sterilized, fish-oil and solid particles are removed by means of centrifuging. The enzymatic protein hydrolysate contains up to 90% free amino acids, cold fish oil, hydroxilaptite (calcium orthophosphate), proteins, highly molecular peptides, vitamin, minerals and calcium salts of phosphorus. The production process involves mixing ground fish waste products with an enzyme source comprising cold-water fish guts and entrails, containing relatively aggressive enzymes that are effective in even mild (slightly alkaline) medium of water. The industrial method 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.
