FIELD: biotechnology, in particular production of bioactive additives from animal-origin raw materials.
SUBSTANCE: claimed method includes collection of ruminant rumen native content, extraction, defecation, filtration, freeze dehydration, and packing. Extraction is carried out for 72 h at 38-42°C in raw materials/water (mineral or spring) of 2:1. Defecation is carried out for 36 h at 10°C. Filtrate is cooled for 48 h at -50°C, and freeze dehydration is carried out for 48 h at 38-40°C, wherein for the first 5 h dehydration is carried out at 10°C and further temperature is increased at a rate of 5°C/h up to 38-40°C.
EFFECT: bioactive substances complex without losses of native characteristics thereof.
