以采自梵净山镜内的地木耳为试材,对其主要营养成分、氨基酸含量、矿物质含量进行了分析测定。结果表明:梵净山地木耳含有丰富的人体所需的矿质元素和至少17种氨基酸,除色氨酸外,必需氨基酸种类齐全;其中,地木耳维生素C含量为(6.20±0.04)mg/100g,粗蛋白质含量为(24.30±0.05)g/100g,必需氨基酸含量(EAA)/氨基酸总量(TAA)为52.04%,必需氨基酸含量(EAA)/非必需氨基酸含量(NEAA)为127.87%,均高于FAO/WHO模式推荐的EAA/TAA约为40%,EAA/NEAA约为60%。
Some of the major nutritional components,including amino acid contents and mineral elements in Nostoc commune Vauch from Mount Fanjing were determined.The results showed that the Nostoc commune Vauch was rich in essential mineral elements and at least 17 amino acids were detected,including 7essential amino acids.Moreover,the contents of protein and vitamin C were(24.30±0.05)g/100 g,(6.20±0.04)mg/100 g,respectively.The ratios of EAA/TAA and EAA/NEAA were 52.04% and 127.87%,respectively,which were significantly higher than the FAO/WHO recommended values.
