FIELD: food, biotechnological and medicinal industries. SUBSTANCE: invention relates to field for preparing biologically active substances. Biologically active substance represents protein hydrolyzate prepared by acid hydrolysis that is carried out up to negative reaction for protein and the following neutralization of peptide-containing raw taken among the following row: animal or fish carcasses, albumin, animal or fish blood, animal or fish meat. Then method involves filtration and preparing hydrolyzate and precipitate followed by drying hydrolyzate. The ready product comprises peptides with molecular mass above 3 000 Da with content 25 wt.-%, not above; optical activity alpha20D of the end product is 5-15, the ratio amine nitrogen : fatty acids : carbohydrates = (10-30) : (0.2-2) : (0.4-5), respectively, and product contains also sodium, chrome, nickel, cobalt, selenium, calcium, potassium, sulfur, phosphorus, chlorine, iron, zinc, copper, manganese. Prepared biologically active substance is used in producing biologically active nutrient supplement, pharmaceutical preparation, biologically active supplement for feeding animals, veterinary preparation, fertilizer, activator of microbiological processes, oral nutrition, perfume- cosmetic agent, hygienic agent, dairy foodstuff, confectionery, baked good, butterfat foodstuff, sauce, alcoholic drink, nonalcoholic beverage, piscine foodstuff, meat foodstuff, macaroni articles, chewing gum and beer. This allows preparing the universal biologically active substance due to broad spectrum of its application and wasteless process for it preparing. Also, chemical composition of biologically active substance shows the close affinity at cellular level with human, animals and plants cells that is provided due to molecular peptide mass and optical density value of biologically active substance. Also, except for physical-chemical indices providing biological activity this substance in its addition to other foodstuffs confers high technological properties to ready foodstuffs, for example: prolonged time storage of ready foodstuffs, enhanced stability of foodstuff, structural- rheological properties in combination with high moisture-retaining capacity. Invention can be used in chemical- pharmaceutical industry, agriculture, in part, in plant growing and animal husbandry, in different branches of food industry and perfume-cosmetic industry. EFFECT: valuable properties of substance. 72 cl
