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 acid
栽培蘑菇平菇半成品粉末状含氮物质的研究
提出了以平菇为原料制备粉末状半成品的工艺。根据感官指标和理化指标对半成品质量进行评价。发现可溶性物质(包括非蛋白质氮和水、盐溶性蛋白质部分的氮)的氮份额占77.06%,不溶性物质的氮份额占22.94%。蘑菇半成品粉末状是完整蛋白质的来源,蛋白质含有18种氨基酸,其中8种是必需氨基酸。粉末状半成品蛋白质的体外消化率比鲜菇高1.3倍。【关键词】蘑菇,平菇,含氮物质,粉末状半成品,氨基酸
