FIELD: biotechnology, food processing industry, medicine.
SUBSTANCE: claimed method includes unossified antler cutting, freezing and crushing together with skin or wool and skin to produce particles having size of at most 0.5 mm, drying and additional crushing in jet mill to produce particles having size of at most 0.1-30.0 mum. Drying of crushed frozen material is carried out simultaneously with additional crushing in jet mill, in gas medium flow with humidity of at most 10 mass % wherein temperature of gas flow in jet mil is automatically maintained at +50°C or less. Produced target ultradispersed powder contains non-radioactive carbon isotope C13 in amount of at least 1.3 % based on total carbon content in finished product. Frozen and crushed material is periodically loaded into jet mill with interval sufficient to produce yield of 70 mass % or more. Period of simultaneous drying and crushing of one material portion between loading cycles is not longer than 1.5-5 hours.
EFFECT: simplified technology, target bioactive product of improved quality.
