Abstract:

The contents of main nutritional components and amino acids of Bohu mushroom were detected, and the international general nutritional value assessment method was applied for the overall nutritional assessment of its protein. The assessment result showed that, compared with button mushroom (Agaricus brunnescens), shiitake mushroom (Lentinus edodes), straw mushroom (Volvariella volvacea) and oyster mushroom (Pleurotus rhodophyllus), the total content of essential amino acids in Bohu mushroom is the highest, which occupies 43.9% of the total amino acids. Moreover, its amino acid score (AAS), chemical score (CS), essential amino acid index (EAAI), biological value (BV), nutritional index (NI) and score of ratio coefficient of amino acid (SRCAA) of protein are 68.6, 43.6, 78.6, 74.0, 32.6 and 65.3, respectively. By the measurement of fuzzy discernment method, its close degree to egg protein is 0.89, which is higher than that of button mushroom, shiitake mushroom, and straw mushroom. In conclusion, the protein nutrient value of Bohu mushroom is very high.
