Study of Nitrogen-Containing Substances of Powdered Semi-Finished Product from Cultivated Mushrooms Pleurotus Ostreatus

Abstract

The technology of obtaining a powdered semifinished product from Pleurotus ostreatus is proposed. Assessment of the quality of the semi-finished product was made according to the organoleptic and physico-chemical indicators. Found that the share of nitrogen of soluble substances, including non-protein nitrogen and nitrogen of water-and salt-soluble protein fractions, accounts for 77.06%, and the share of nitrogen of insolu-ble substances -22.94%. Powdered semi-finished product from mushrooms Pleurotus ostreatus are the source of complete protein, which includes 18 amino acids, including 8 essential ones. Digestibility (in vitro) of proteins of the powdered semi-finished product is 1.3 times higher than the digestibility of fresh mushrooms. Keyword-mushroom, Pleurotus ostreatus, nitrogencontaining substances, powdered semi-finished product, amino acidI.

Cultivation of oyster mushroom to combat pandemics: medicinal and social aspects

“…The fruiting bodies of Pleurotus ostreatus require little environmental restrictions, are rarely attacked by diseases and pests, and can be grown in an easy and inexpensive manner. Due to all of this, Pleurotus ostreatus cultivation is a superior alternative to other mushroom production (Myachikova et al, 2019). Although the white oyster mushroom is a member of the consumption mushroom family that feeds on decomposing wood, there are many other species that may be found in nature, each of which has unique traits.…”
