FIELD: chemistry.
SUBSTANCE: invention relates to biotechnology and represents a method of producing a natural L-amino acid - peptide biocomplex. The method involves preparation of material in form of a collection of native paunch manure of ruminant animals, extraction of said material, filtration and cooling for 6 hours at temperature (-50°C), sublimation drying and packing. Extraction is carried out with 2.0-3.0% aqueous NaCl solution in volume ratio of material to extraction agent equal to 1:1 for 45-48 hours at 18-20°C while stirring constantly. Sublimation drying is carried out for 20-24 hours at 43-45°C.
EFFECT: invention enables more efficient production of L-amino acid - peptide complex with high content of essential amino acids.
