摘要:

以短链直链淀粉和磷脂为原料,制备得到直链淀粉磷脂复合物,该复合物经红外光谱、X-射线衍射和差示量热分析,结果显示复合物的结构与原短链直链淀粉结构发生了变化,红外光谱分析在1730.04cm-1处出现吸收峰,表明磷脂与短链直链淀粉发生了络合,形成了淀粉磷脂复合物;X-射线衍射图谱证实,复合物为V型结晶结构,复合物经紫外分光光度法测试,其磷脂的质量分数量为19.80%。

Abstract:

Amylose-phospholipid complex was prepared with short chain amylase and phospholipid. IR spectroscopy,
X-ray diffractometry and DSC analyses showed structural changes of the native amylase after this complexation reaction and
an absorption peak at 1730.04 cm-1, confirming the formation of complex. Moreover, the structure of this complex showed
V-shaped crystals and it contained 19.80% phospholipid.

Key words: amylose, phospholipid, complex
