ISOLATION, STRUCTURE AND PHYSICO-CHEMICAL PROPERTIES OF CHITIN-GLUCAN COMPLEXES OF HIGHER FUNGI

The article is devoted to the study of isolation processes, chemical structure and rheological properties chitin-glucan complexes from biomass Armillaria mellea. Because studies, it was found that yield ranged 11.0 24.9% with a degree deacetylation 24 55%. maximum obtained by treating fruiting bodies fungi at stage deproteinization 3% aqueous solution sodium hydroxide mechanical stirring 225 rpm for 60 min 75±5°C. It shown correlates values alkali concentration used. IR spectra samples include absorption bands characteristic stretching bending vibrations bonds chitin glucan links coincide other fungi. has been established viscosity characteristics 1% complex in 2% hydrochloric acid are 14 190 times lower than 5% 10% solutions, respectively. Increasing shear rate makes possible detect decrease all studied solutions. Storage 7 days 25±2°C accompanied viscosity; 5 solutions remains stable.
