黄伞菌丝蛋白质营养价值评价

本文测定了黄伞Pholiotaadiposa菌丝粗蛋白含量和氨基酸组成,采用国际上通用的营养价值评价方法,对其蛋白质的营养价值进行全面评价,并与营养价值较高的白灵侧耳Pleurotusnebrodensis、刺芹侧耳Pleurotuseryngii和金顶侧耳Pleurotrscitrinopileatus进行比较。分析结果表明,黄伞菌丝的必需氨基酸含量最高,占其氨基酸总量的43.9%,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92.0、71.3、88.5、84.8、40.4和78.8,六项指标均比参比食用菌高。结果说明黄伞菌丝具有很高的营养价值。

NUTRITIONAL VALUE EVALUATION OF THE PROTEIN IN PHOLIOTA ADIPOSA MYCELIA

The crude protein and amino acids of Pholiota adiposa mycelia were detected. The international adopted nutrient value assessment method was applied to the overall assessment of the protein nutrient value of Pholiota adiposa mycelia. The result was compared with the protein nutrient value of Pleurotus nebrodensis , Pleurotus eryngii and Pleurotus citrinopileatus. The assessing result showed that the total essential amino acid in Pholiota adiposa mycelia was the highest, making up 43.9% of the total amino acids. The 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 its protein were 92.0, 71.3, 88.5, 84.8, 40.4 and 78.8 respectively. The six indexes of Pholiota adiposa mycelia were higher than those of Pleurotus nebrodensis , Pleurotus eryngii and Pleurotus citrinopileatus. The results showed that the protein nutrient value of Pholiota adiposa mycelia was very high.
