河西地区韭菜营养品质分析

对河西地区12份不同品种的韭菜的还原糖、Vc、蛋白质含量进行了测定,结果表明,不同类型(品种)韭菜的还原糖、Vc、蛋白质含量差异较大。酒泉丰乐河海子沟野韭的Vc含量最高,达460μg/g,金昌地方品种Vc含量最低,仅为60μg/g;山丹柴胡子沟蒙古韭(Allium mongolicum)还原糖含量最高,达12.7μg/g,肃南甘沟野韭还原糖含量最低,为4.8μg/g;张掖地方品种蛋白质含量最高,达61.9μg/g,张掖寺大隆野韭和山丹柴胡子沟蒙古韭含量最低,均为46.9μg/g。由此说明,河西地区12份不同类型(品种)韭菜的还原糖、Vc、蛋白质含量均存在着一定的差异,栽培种与野生种间差异没有明显的变化规律。

Analysis on nutritional quality of leeks in Hexi region

The reducing sugar, Vc, protein content of 12 different varieties of Allium spp. in Hexi region were measured in this paper. The results indicated that: there were obvious differences in the reducing sugar, Vc, protein content of different types (varieties) leeks. The highest Vc content in leek (A.ramosum) achieved 460 μg/g,the least Vc content in Jinchang local leek varieties was 60 μg/g. The highest content of the reducing sugar in leek (A.mongolicum) achieved 12.7 μmg/g, the least content of the reducing sugar in leek (A.ramosum) was 4.8 μg/g. The highest protein content of Zhangye local leek varieties achieved 61.9 μg/g, the least protein content in A.ramosum and A.mongolicum both were 46.9 μg/g. So there were some differences in reducing sugars, Vc, protein content of 12 different types (species) leeks in Hexi region, but there were not obvious variation of differences between cultivars and wild species.
