以秦巴山区野生松乳菇子实体为材料 ,分别对其菌盖和菌柄样品中氨基酸、粗蛋白、粗脂肪、粗纤维、总糖、灰分及微量元素的含量进行了测定。结果表明 :在所测定的 1 7种氨基酸中 ,菌盖含有 1 7种 ,菌柄含 1 6种 ,氨基酸总含量分别为 1 9.89%和 1 3 .79% ;必需氨基酸分别占氨基酸总量的 3 6.75 %和 3 5 .95 %。菌盖和菌柄中粗蛋白、粗脂肪、粗纤维、总糖、灰分含量分别为 2 4 .2 7% ,1 9.0 3 % ;6.84 % ,5 .0 2 % ;1 1 .5 2 % ,1 5 .2 6% ;3 7.4 1 % ,2 3 .89%和 7.4 2 % ,5 .2 8%。钙、铁、锌、铜、锰 5种微量元素中 ,铁含量最高 ,在菌盖和菌柄样品中分别为 0 .1 68% ,0 .1 2 %

Determination of Amino Acids and Other Nutritious Components in Lactarius deliciosus

The amino acids and other nutritious components in the fruitbody of Lactarius deliciosus were determined. The results showed that there are 17 kinds of amino acids in the mushroom cover and 16 kinds in mushroom stem. The two parts of the mushroom contain 24-17% and 19.03% of crude protein in which 36.75% and 35.95% of amino acid are essential amino acids, 6.84% and 5.02% of crude fat, 11.52% and 15.26% of crude fiber, 37.41% and 23.89% of total sugar, and 7.42% and 5.28% of ash respectively. The mushroom contain La, Fe, Zn, Cu, and Mn five trace elements also in which the content of Fe is the highest which amount to 0.168% in the two parts of the mushroom, respectively.
