摘要
以福建古田、福建建阳、福建顺昌、浙江、贵州和云南地区的6种竹荪子实体为材料,测定了其粗蛋白、粗脂肪、粗纤维、粗多糖、灰分、矿质元素和氨基酸含量。6个供试地区的竹荪子实体均富含蛋白、多糖与粗纤维,且脂肪含量低,但多糖含量差异明显,来自浙江的样品粗多糖含量达到30.68%,来自贵州的样品多糖含量为18.68%;此外,竹荪子实体富含Ca、Mg、Fe和Zn等人体必需的矿质元素,其中来自浙江和贵州的样品中含量最为丰富;竹荪子实体中Hg含量超标可能是一个普遍现象;通过氨基酸分析,竹荪蛋白质的限制性氨基酸为赖氨酸,不同产地的竹荪样品存在较大差异。
In this paper,the fruiting bodies of Dictyophora indusiata from 6 different regions,such as Gutian, Jianyang and Shunchang in Fujian Province,Zhejiang,Guizhou and Yunnan Province,were taken as the materials. The contents of crude protein,crude fat,crude fiber,crude polysaccharides,ash,mineral elements and amino acids were determined. It was showed that the fruiting bodies from different regions all enriched crude protein,crude polysaccharides and crude fiber with low crude fat,although,there was a marked difference in crude polysaccharides. The content of crude polysaccharides of the sample from Zhejiang was 30.68% when the sample of Guizhou was about 18.68%. The fruiting bodies of Dictyophora indusiata were rich in essential mineral elements such as Ca,Mg,Fe and Zn. The most abundant samples were the samples from Zhejiang and Guizhou; in the meanwhile,excessive levels of Hg might be a common situation about Dictyophora indusiata. By amino acid analysis,limited amino acid of Dictyophora indusiata was Lysine and it＇s changing with the origins.
