摘要
[Objective] The aim was to identify the nourishing compositions of Fagopyrum tataricum and screen high-quality buckwheat materials.[Method]A total of 10 species of buckwheat including T32,T31,T30,T14,T28,T23,T24,Jiujiang Buckwheat,Weiku 2 and WK-1 were employed as experimental materials,and the contents of the nutritional components（including total sugar,reducing sugar,starch,amylose,amylopectin and protein）,flavonoids content,physical and chemical characteristics（such as expansive force,water holding capacity）of them were respectively measured.[Result]There were significant differences in contents of soluble protein,total sugar,reduced sugar,amylase and expansive force among the cultivars,but the differences in contents of total starch,amylopectin,flavonoids content and water holding capacity were not significant.[Conclusion]The starch content in seeds of buckwheat was relatively high,and amylopectin was the main composition.
[目的]明确不同苦荞材料的营养保健成分含量,筛选出优质苦荞材料。[方法]以T32、T31、T30、T14、T28、T23、T24、九江苦荞、威苦2号和WK-110种苦荞材料为试材,测定了其营养成分(总糖、还原糖、淀粉、直链淀粉、支链淀粉和蛋白质)含量、黄酮含量及理化特性(膨胀力和持水力)。[结果]可溶性蛋白质、可溶性总糖、还原糖、直链淀粉含量及膨胀力品种间差异显著,而总淀粉、支链淀粉、黄酮含量及持水力品种间差异不显著。[结论]苦荞籽粒中淀粉含量较高,以支链淀粉为主。
