摘要
[目的]分析不同淮山药品种(资源)的营养品质。[方法]以9个淮山药品种:桂淮2号、桂淮5号、桂淮6号、GY2、GY23、GY47、GY62、GY69和双胞山药为材料,测定他们的水分、粗蛋白、脂肪、氨基酸总量、氨基酸组分及矿物质含量。[结果]在供试品种中,GY2的营养品质较优,除其蛋白质含量排第2外,其总氨基酸、可溶性糖、脂肪、皂甙及各种矿物质含量均居首位;桂淮5号为高蛋白、高锌品种,其蛋白质和锌含量分别为3.03%和4.65 mg/kg;GY23、GY62和GY69为高淀粉品种,其鲜薯淀粉含量分别为22.0%、27.9%和23.4%。[结论]供试淮山药品种的品种特色比较明显,GY2的营养品质较优。
[Objective] The study was to analyze the nutritional quality of different Dioscorea opposita Thunb varieties （resources）. [Method] With 9 D. opposita varieties such as Guihuai 2, Guihuai 5, Guihuai 6, GY2, GY23, GY47, GY62, GY69 and double cell Chinese yam as tested materials, their content of water, crude protein, fat, total amino acid, amino acid components and mineral matter content were detected. [ Result ] In the tested inatefials, the nutritional quality of GY2 was better, and except its protein content ranks the second, its content of total amino acid , soluble sugar, fat, saponin and each mineral matter all rank the first. Guihnai 5 was the variety with high protein and high Zn, and its content of protein and Zn were 3.03% and 4.65 mg/kg resp. GY23, GY62 and GY69 were high starch varieties, and their starch content in fresh root tubers were 22.0%, 27.9% and 23.4% resp. [Conclusion] The variety characteristics of the tested D. opposita varieties were obvious, and the nutritional quality of GY2 was better.
