中文摘要: 以产自云南香格里拉的藜麦为研究对象,对其品质成分进行分析,包括水分、粗脂肪、直链淀粉、支链淀粉、可溶性多糖、水溶性蛋白、多酚、游离氨基酸总量、氨基酸组成和矿物质元素。并采用同时蒸馏萃取(simultaneous distillation extraction,SDE),气相色谱-质谱联用(gas chromatography-mass spectrometry,GC-MS)技术分析藜麦挥发性成分。结果显示,与常见谷物(小麦、稻米、玉米)相比,香格里拉藜麦淀粉含量较低,含有大量优质蛋白质和多不饱和脂肪酸以及丰富的多糖和矿质元素,并且其必需氨基酸组成较为均衡。
Abstract:The quality components of quinoa(Chenopodium quinoa Willd)from Shangri-La,Yunnanwere studied.Content of moister,crude fat,amylose,amylopectin,water soluble polysaccharides,water soluble protein,total poplyphenols,total amino acid,amino acid composition and mineral elements were investigated.Simultaneous distillation extraction coupled with gas chromatography-mass spectrometry(SDE-GC-MS)was used to analyze volatile components.Results showed that Shangri-La quinoa has low content of starch,rich in fine protein,polyunsaturated fatty acids,polysaccharides and mineral elements,and has well-balanced essential amino acid composition in comparison withommon grains(wheat,rice and maize)Therefore.
