The Chemical Components in Fruit-Bodies of Lyophyllum shimeji (Honshimeji Mushroom) Grown on Artificial Bed-Blocks

Abstract

The contents of proximate components, low molecular weight carbohydrates, organic acids, free amino acids and 5'-nucleotides in fruit-bodies of Lyophyllum shimeji (Honshimeji Mushroom) grown on artificial bed-blocks were examined. The crude protein content was 30.4% and the carbohydrate was 57.7% in dry weight. The low molecular weight carbohydrate content was 14.6% in dry weight. In low molecular weight carbohydrates component, trehalose was the dominant and was 12.0% in dry weight. The organic acid content was 3.81% in dry weight. In organic acids component, malic, citric, fumaric and succinic acids were the dominant. The total free amino acid content was 2.88% in dry weight. In free amino acids component, glutamine, ornithine, arginine, alanine, glutamic acid and glycine were the dominant. The 5'-GMP content was 0.31% in dry weight.
