Physicochemical Properties of Pleurotus eryngii

Physicochemical properties such as proximate components, minerals, amino acids, organic acid and free sugars of Pleurotus eryngii were investigated. Among the proximate components of Pleurotus eryngii contents of crude protein and total sugar were higher than that of others. The contents of magnesium and sodium were higher than that of other minerals. Hypoproline content was the highest in free amino acid. Among the amino acid, the contents of arginine, lycine, glutamic acid and phenylalanine were 509.03, 410.53, 190.05 and 150.63 mg, respectively. Organic acids such as citric acid, oxalic acid, formic acid and malic acid were analyzed, contents of citric acid and lactic acid were higher than that of others. Among the free sugars, the content of glucose was the highest, followed by fructose, ribose, galactose, lactose, arabinose and maltose.
