美味蘑菇子实体营养品质分析

Fruiting Body of Agaricus sinodeliciosus: Nutritional Quality Analysis

为了解美味蘑菇的营养含量,笔者用食品安全国家标准法测定了驯化种植的美味蘑菇(Agaricus sinodeliciosus)的营养品质。结果表明,美味蘑菇粗蛋白含量为33.75 g/100 g,含有氨基酸种类18种,其中8种必须氨基酸含量占氨基酸总量的40.5%,必需氨基酸与非必需氨基酸比值(E/N)为68.1。氨基酸评分、化学评分、必需氨基酸指数分别为8.06、5.56、75.8,鲜味氨基酸总量为5.4312 g/100 g,除此之外还含有丰富的矿质元素,其中硒、锌、硼和钠的含量显著高于对照组。美味蘑菇是一种蛋白含量丰富、脂肪含量低、味道鲜美、适合大众人群食用的营养价值很高的珍稀食用菌,具有较高价值的开发前景。

The paper aims to study the nutritional contents of Agaricus sinodeliciosus.The nutritional quality of domesticated Agaricus sinodeliciosus is determined by the National Standard Law on Food Safety.The results show that:the crude protein of Agaricus sinodeliciosus is 33.75 g/100 g,there are 18 types of amino acids in it and the content of 8 essential amino acids accounts for 40.5%of the total,the ratio of essential and unessential amino acids(E/N)is 68.1;the amino acid score,chemical score and essential amino acid index is 8.06,5.56,75.8,respectively;the content of umami amino acids is 5.4312 g/100 g;in addition,there are also rich mineral elements,and the contents of selenium,zinc,boron and sodium are significantly higher than those in the control group.Agaricus sinodeliciosus is a kind of rare edible fungus with rich protein content,low fat content,delicious taste and high nutritional value,and is suitable for the general population,and it has a good prospect of development and utilization.
