FIELD: food industry. ^ SUBSTANCE: method provides for depth cultivation of basidium fungi Pleurotus ostreatus on nutrient medium of the following composition (g/l): soya flour - 21, KH2PO4 - 3.5, MgSO4 - 0.4, milk whey - 200 ml, water - up to 1 litre. Mycelium is exposed to deep freezing with further defrosting. Then its disintegration is carried out. Food fibres are cleaned by alternating treatment with cold and hot water, mix of 1 M sodium carbonate or sodium hydroxide with ethanol in the ratio of 1:2 and 0.5 M solution of citric acid. Yield of food fibres makes 16-18% of dry biomass, content of chitin - 16-19%, glucan - 40-50% of dry mass of food fibres. ^ EFFECT: food fibres with high content of chitin. ^ 4 ex |
