摘要
以野生粗柄鸡枞菌子实体为实验材料,通过化学分析、仪器分析法测定了粗柄鸡枞菌菌盖、菌柄和菌根干粉的营养成分。结果表明,粗柄鸡枞菌子实体的不同部位的营养成分含量有差异,总糖、还原糖、粗脂肪、5种矿物元素(钾、钠、铁、镁、锌)在菌盖中含量较高,尤其菌盖中铁含量(1 471mg/kg)分别是菌柄的3倍,菌根的4倍;粗蛋白在菌柄中含量较高;灰分、粗纤维、2种元素(锰、铜)在菌根中含量较高。粗柄鸡枞菌不同部位的砷、汞元素含量无显著性差异(P>0.05),铅元素在菌根中含量较高,但均符合国家食用菌卫生标准中限量范围。
Taking sporocarp of wild Termitomyces robustus as experimental material, the nutritional components in different parts of sporocarp in T. robustus were analyzed by chemical analysis and instrumental analysis. Results showed that there were differences among different parts of sporocarp in T. robustus. The contents of total sugar, reducing sugar, crude fat, mineral elements （K, Na, Fe, Mg, Zn） were the highest in pileus, the content of Fe （1 471 mg/kg） was especially high, which was 3 and 4 times of the stipes and the roots, respectively. The content of crude protein was higher in stipe than other parts. The ash content, crude fiber, mineral elements of Mn and Cu were the highest in roots. There were no significantly differences between arsenic and mercury in different parts of sporocarp in T. robustus. The content of lead was high in roots, but within the limits of the national hygienic standard for edible fungi.
