FIELD: process engineering.
SUBSTANCE: in compliance with this process, minced biomass of insect worms is fed into alkaline solution at the ratio of 1:1-1:8, 0.01-1.0% and mixed for 5-30 minutes at 25-100°C. Then, after inoculation by lactate bacteria, said mix is fermented for 1.5 to 7.0 hours under stationary conditions at 25-45°C. Chitin is separated, flushed with water and subjected to additional demineralisation by acid solution. Acid solution is removed, chitin is flushed and dried.
EFFECT: production of high-quality chitin.
