| 摘 要： | 选择3个不同类型甘薯品种,以提取获得的抗性淀粉为研究对象,通过X-射线衍射分析仪、差示扫描量热分析仪(DSC)、快速黏度测定仪(RVA)、紫外-可见吸收光谱仪、近红外光谱分析仪(NIRS)和扫描电镜等仪器分别对甘薯原淀粉和其对应抗性淀粉晶体结构类型、熔融温度、淀粉糊化特性、平均聚合度和淀粉分子结构等理化特性深入研究与分析。结果表明,不同甘薯品种间抗性淀粉熔融温度具一定差异,抗性淀粉与其原淀粉间糊化特性、晶体结构等特性呈明显差异。

| Abstract: | The physicochemical properties of resistant starch (RS) and starch from three typical sweet potato genotypes were studied by adopting x-ray diffraction, differential scanning calorimetry, rapid viscosity analysis, near infrared reflectance spectrophotometer analysis and scanning electron microscope. Results show that there are some difference in melting temperature among the RSs from different sweet potato genotypes, and also significant differences in pasting temperature and crystal structure between their starch and RS. |
