Abstract
Nitrogen compounds constitute the greatest proportion of the dry weight of mushrooms. These nitrogen compounds are partly protein and partly non-protein. A modified Heneberg-Stohman's method was used to separate non-protein from protein nitrogen, as well as to determine ‘raw fiber’ content in mushrooms, since the methods used previously for this purpose are time-consuming and complicated. Elemental analysis of ‘crude fiber’ was performed to confirm the uniformity of isolated products. The content of total ‘crude fiber’ (fungin) and the proportion of chitin and cellulose in it were determined. The chitin content of 15 species of field grown edible mushrooms was in the range of 1.87–6.93% of total dry mass and 34.51–67.72% of isolated fungin.
