| 摘 要： | 分析结果表明,香菇的菌柄与菌盖中蛋白质氨基酸均为18种,缺少谷氨酰胺(Gln)和天冬酰胺(Asn),其中,含量最高的是谷氨酸(菌柄为11.03 mg/gDW,菌盖为12.57 mg/gDW)。菌盖与菌柄均含必需氨基酸、半必需氨基酸10种,其中精氨酸含量(菌柄为10.73 mg/gDW,菌盖为11.84 mg/gDW)。必需氨基酸的含量十分接近于非必需氨基酸的含量(比率为1.00∶1.04),无论总氨基酸含量还是必需氨基酸含量,菌盖中的皆略高于菌柄中的。

| Abstract: | ShiitakeLentinus edodes(Berk.)Singer] is an important edible fungus of rich nutrition.Analytic results indicated that there were 18 amino acids,10 of which are essential amino acids in the cap and the stipe.Glutamic acid(Glu) and arginine(Arg) possessed the first site in the contents of total and essential amino acids respectively.The content of essential amino acids was close to that of nonessential amino acids(its ratio was 1.00∶1.04).In addition,total and essential amino acid contents in the cap are slightly higher than those in the stipe. |
