摘　　要：目的:分析常见谷物品种生糖指数和阿拉伯糖木聚糖含量的差异,为快速查找到低生糖指数和高阿拉伯糖木聚糖膳食纤维谷物食源提供科学依据。方法:以常见18种谷物为研究对象,采用酸法水解,利用高效液相色谱法分析常见谷物的生糖指数和阿拉伯糖木聚糖含量。结果:不同谷物品种生糖指数和阿拉伯糖木聚糖的含量差异显著。18种谷物中,每100g绝干原料生糖指数(以葡萄糖的量计)排名前五位的谷物(低至高)分别是:黑芝麻1.75g、黑豆2.70g、花生3.26g、黄豆4.20g、红芸豆22.72g,其他杂粮品种生糖指数都均大于22.72 g;每100g绝干原料阿拉伯糖木聚糖含量(高至低)排名前五的分别是:红豆8.22g、黄豆7.71g、黑豆7.53g、绿豆6.55g、红芸豆6.05g,其他谷物阿拉伯糖木聚糖含量均小于6.05g。结论:补充低生糖指数的谷物,推荐优选黑芝麻、黑豆和花生,补充高含量阿拉伯糖木聚糖膳食纤维优选豆类,且含量大于6.05g/100g绝干原料。Objective To help people quickly find low glucose and high arabinoxylan dietary fiber of whole grains,we determined and compared 18 different varieties of whole grains.Method Totally 18 common varieties of whole grains as the research objects,which were hydrolyzed by dilute sulfuric acid,glucose and arabinoxylan in whole grains hydrolysates was measured by HPLC.Result A significant difference in the glucose and arabinoxylan content in different varieties of whole grains.Among the 18 varieties of whole grains,the glucose content(low to high)of whole grains in the per 100g,the glucose content in No.1 was the black sesame,which was 1.75g,the second was the black soybean,its glucose content was 2.70g,the third was the peanut in 3.26g,the fourth was the soybean in 4.20g,the fifth was the red kidney bean in 22.72g,and the other whole grains varieties more than 22.72 g.The top five contents of arabinoxylan(high to low)were red beans 8.22g,soybeans 7.71g,black beans 7.53g,mung beans 6.55g,kidney beans 6.05g,and arabinosexylan content in other whole grains was less than 6.05g.Conclusion It is recommended in select black sesame,black soybean and peanut as supplements of whole grains with the low glucose content.In order to supplemente more arabinoxylan dietary fiber of whole grains,the best choice was beans in whole grains,and the content of which is more than 6.05g/100g dried whole grains.
