【摘要】 对 3种藕淀粉颗粒的特征性质进行了研究。研究表明 ,藕淀粉颗粒多为长 10～ 5 0 μm ,宽 4～ 15 μm的长粒形 ,平均粒径长为 2 4 5～ 2 6 8μm。表面有轮纹 ,淀粉颗粒的一端有偏光十字 ,藕淀粉的糊化温度 6 8 0～81 5℃ ,直链淀粉含量 2 3 2 %～ 2 5 1%。利用藕淀粉的显微形态特征 ,能有效鉴别传统藕粉产品的掺假。更多还原

【Abstract】 The granule properties of three kinds of lotus root starch were researched. The results showed that granules of lotus root starch mostly were long particles of 10～50*#μm long and 4～15*#μm wide with mean length 24.5～26.8*#μm. The cricoid ridges on granule surface and Maltese cross in one end of granule were observed. The starch has gelatinization temperature from 68.0℃ to 81.5℃, and contains 23.2%～25.1% amylose content. The adulterated Oufen products were discriminated effectively with micro- morphologic property of lotus root starch granules.更多还原
