[目的]筛选保健功能较好的荞麦资源.[方法]以前期得到的营养保健成分较高的荞麦材料T330和T429及荞麦壳为试验材料,研究其膨胀力、持水率和束缚重金属离子能力的差异.[结果]荞麦材料间的膨胀力和持水率存在差异.膨胀力在不同荞麦材料间表现为荞麦壳>T429>T330,差异达显著水平;持水力表现为T330>荞麦壳>T429.荞麦壳对Pb和Cu的最大束缚浓度及最小束缚浓度均高于其他2份荞麦资源.[结论]荞麦壳具有较好的理化特性.%[ Objective ] To sift out fine buckwheat resources. [ Method ] Change of physical and chemical properties of buckwheat were studied on the material which based on the former study which we had higher nutritive component T330 and T429. At the same time, their buckwheat shell was also used. [ Result] The buckwheat had differences in expansion ability and water preservation ability. The expansion capacity in different kinds of buckwheat was Buckwheat ＞ T429 ＞ T330, reaching significance level; water holding capacity of these buckwheat would be T330 ＞ buckwheat ＞ T429. [Conclusion] The buckwheat shell has the better physical and chemical properties.
