摘　　要：为了研究不同藜麦的品质性状,选取了全国主要藜麦栽培地区的6个藜麦品种(系),对其主要品质性状进行了分析。结果表明,不同地区主栽的藜麦品种(系)在主要品质性状上存在显著差异。甘肃藜麦(陇藜4号)蛋白质含量略低于内蒙古藜麦(蒙藜1号)。总膳食纤维含量、总皂苷含量变化范围较大,其中总膳食纤维含量内蒙古藜麦(蒙藜1号)最高,为110.2 g/kg;山西藜麦(LM3)最低,为69.0 g/kg。总皂苷含量青海藜麦(GRM-1)最高,为168.6 g/kg;河北藜麦(LM1)最低,为97.5 g/kg。脂肪含量变化范围不大,青海藜麦(GRM-1)最高,为63.3 g/kg;山西藜麦(LM3)最低,为54.0 g/kg。淀粉和灰分含量变化不明显。相关性分析发现,蛋白质与水分极显著正相关,与总膳食纤维显著正相关;总皂苷含量与灰分极显著负相关;总膳食纤维和淀粉极显著负相关;淀粉与脂肪极显著负相关。聚类分析发现,甘肃藜麦(陇藜4号)品质和云南藜麦(LM2)、内蒙古藜麦(蒙藜1号)较为相近,与河北藜麦(LM1)品质相差最远,这表明甘肃藜麦(陇藜4号)在加工、功能成分提取及相关产品的开发等方面具有与云南藜麦(LM2)、内蒙古藜麦(蒙藜1号)相似的潜力。To study the quality traits of different quinoa varieties,6 main quinoa varieties(lines)cultivated in major quinoa growing regions of China were selected for analysis.The results showed that there were significant differences in the main quality traits of quinoa varieties(lines)cultivated in different regions.The protein content of Gansu quinoa(Longli 4)was slightly lower than that of Inner Mongolia quinoa(Mengli 1).The total saponin content and total dietary fiber content varied greatly,with Inner Mongolia quinoa having the highest total dietary fiber content(110.2 g/kg)and Shanxi quinoa the lowest(LM3,69.0 g/kg).The total saponin content was highest in Qinghai quinoa(GRM-1,168.6 g/kg)and lowest in Hebei quinoa(LM1,97.5 g/kg).The range of ether extract was not large,with Qinghai quinoa having the highest(GRM-1,63.3 g/kg)and Shanxi quinoa the lowest(LM3,54.0 g/kg).Starch and ash contents did not show significant variations.Correlation analysis revealed that protein was positively correlated with moisture(P<0.01),total dietary fiber(P<0.5).Total saponin content was negatively correlated with ash content(P<0.01).Total dietary fiber was highly significantly negatively correlated with starch.Starch was negatively correlated with fat content(P<0.01).Cluster analysis found that the quality of Gansu quinoa(Longli 4)was more similar to that of Yunnan quinoa(LM2)and Inner Mongolia quinoa(Mengli 1),and most different from that of Hebei quinoa(LM1).This indicates that Gansu quinoa(Longli 4)has similar potential for processing,functional ingredient extraction,and related product development as Yunnan quinoa(LM2)and Inner Mongolia quinoa(Mengli 1).
