摘　　要：以52种不同品种及粒色的青稞为原料,探究不同粒色青稞对于其营养成分含量的影响。结果表明:不同粒色青稞的营养成分含量存在一定差异,其中黑色青稞的蛋白质、灰分含量最高,脂肪含量最低;蓝色青稞总淀粉、脂肪含量最高,但直链淀粉和纤维含量最低;紫色青稞的直链含量较高;普通黄色青稞的纤维含量最高;有色青稞的β-葡聚糖含量较高,尤其以黑青稞最为突出。另外,赖氨酸是不同粒色青稞蛋白质中的第一限制氨基酸,蓝色青稞蛋白中必需氨基酸比例最高,黑色青稞蛋白营养价值最高,且有色青稞中含有较高含量的赖氨酸。本研究可为不同粒色青稞的相关产品的开发利用提供参考。To use 52 different varieties and grain colors of highland barley as raw materials,We explored the impact of different grain colors of highland barley on its nutritional content.The results showed that there were certain differences in the nutritional content of different grain colors of barley,with black barley having the highest protein and ash content and the lowest fat content.Blue barley had the highest total starch and fat content,but the lowest amylose and fiber content.Purple barley had a higher straight-chain content.The fiber content of ordinary yellow barley was the highest.Beta glucan of Colored barley was relatively high,especially black highland barley.In addition,lysine was the first limiting amino acid in proteins of different grain colors of highland barley.The proportion of essential amino acids in blue highland barley protein was the highest,while the nutritional value of black highland barley protein was the highest,and colored highland barley contained a higher content of lysine.This study can provide reference for the development and utilization of related products of barley with different grain colors.
