摘要
[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号和威苦1号10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、直链淀粉含量和膨胀力在某些品种之间存在显著差异,而所有品种在总淀粉、支链淀粉、黄酮含量和持水力方面均差异不显著。[结论]苦荞籽粒中淀粉含量较高,以支链淀粉为主。
[Objective] The aim was to identify the nourishing compositions of Fagopyrum tataricum,and screen high quality buckwheat material. [Method] A total of 10 types of buckwheat including T32,T31,T30,T14,T28,T23,T24,Jiujiang Buckwheat,Weiku 2,and Weiku-1 were employed as experimental material,and the contents of the nutritional components（including total sugar,reducing sugar,starch,amylose,amylopectin,protein） ,flavonoids contents,physical and chemical characteristics（such as expansive force,water holding capacity） of them were 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 the seeds of buckwheat was high,mainly with amylopectin.
