中文摘要: 以安顺山药为原料，通过单因素试验（one-factor-at-a-time method，OFAT）及响应面分析法（response surface methodology，RSM）优化压热法制备抗性淀粉（resistant starch，RS）的工艺，并对抗性淀粉的结构进行X-射线衍射仪（X-Ray Diffraction，XRD）、傅立叶红外光谱仪（Fourier Transform Infrared Spectrometer，FT-IR）和扫描电镜（Scanning Electron Microscope,SEM）等表征分析。结果显示：通过工艺条件优化，在淀粉乳百分含量为14%，pH值为6.0，压热温度为112℃，压热时间为1.5 h时，抗性淀粉得率为24.83%，与响应面预测值高度相符，结果合理可靠。
Abstract:Using Anshun yam as the experimental material，one-factor-at-a-time method and response surface methodology were applied to optimize the autoclave method for preparing resistant starch.Meanwhile，the structure of yam RS was analyzed by X-Ray Diffraction，Fourier Transform Infrared Spectrometer and Scanning Electron Microscope.It was found that by optimizing the preparation process，the yield of resistant starch was 24.83%when the starch milk percentage was 14%，pH value was 6.0，pressure heat temperature was 112℃and pressure heat time was 1.5 h respectively.The experimental value was highly agreed with the predicted value of response surface.
