摘要:

本实验测定了博湖大蘑菇的营养成分和氨基酸组成,采用国际上通用的评价方法对其营养进行评价,并与双孢蘑菇、香菇、草菇和平菇进行比较。结果表明,博湖大蘑菇的必需氨基酸含量最高,占其氨基酸总量的43.0%,其蛋白质的氨基酸评分(AAS)、化学评分(CS)、必需氨基酸指数(EAAI)、生物价(BV)、营养指数(NI)和氨基酸比值系数分(SRCAA)分别为68.6、43.6、78.6、74.0、32.6 和65.3;借助模糊识别法得出博湖大蘑菇与鸡蛋蛋白质的贴近度为0.89,高于双孢蘑菇、香菇及草菇。证实博湖大蘑菇具有很高的营养价值。

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.
