FIELD: biotechnology, food processing industry, pharmaceutical industry.
SUBSTANCE: claimed method includes extraction of , beta-carotene from mycelium mass, separation of beta-carotene crystal suspension in lipids form extract. Further lipid suspension is alcoholyzed with alcohol in ratio of 1:2-1:5 at boiling temperature in presence of catalyst, such as alkali metal alcoholate. Beta-carotene crystals obtained after filtration are 2-3 times washed with alcohol in ratio of 1:1,5-1:3.
EFFECT: increased yield of target product; decreased alcohol and reagent consumption; accelerated process.
