| 摘 要： | 采用微波—酶法制备小麦抗性淀粉,用扫描电子显微镜(SEM)观察小麦抗性淀粉颗粒结构,用X-射线衍射仪测定其结晶结构,并测定抗性淀粉持水性、乳化性、粘度等物理特性。研究结果表明,与原小麦淀粉相比,小麦抗性淀粉表面粗糙,形状变得不规则,结晶结构为B型和V型结合体,持水性大于原淀粉,而乳化能力和乳化稳定性均低于原淀粉;在相同溶液浓度条件下,抗性淀粉粘度比原淀粉低得多。

| Abstract: | The wheat resistant starch was prepared by the microwave-enzyme method.The granule structure of wheat resistant starch was observed by scan electron microscope.The crystallization of wheat resistant starch was determined by X-ray diffractometer.The water holding capacity and emulsification property and viscosity of wheat resistant starch was determined.The results showed as follows:the granule structure of wheat resistant starch was rough and its shape was irregular,its crystallization structure was combina... |
