摘要:

以糯米淀粉为原料,3- 氯-2- 羟丙基三甲基氯化铵(CHPTMA)为阳离子醚化剂,碱性条件下,采用湿法工艺制备阳离子糯米淀粉。结果显示:在糯米淀粉5.0g、NaCl 3.0g、反应温度50℃、反应时间4h、糯米淀粉:醚化剂=100:8.00(g/g),醚化剂: NaOH=1.00:1.94(物质的量比)优化条件下,制得糯米阳离子淀粉的含氮量0.370%,对应的取代度0.0613;与原淀粉比较,阳离子糯米淀粉的黏度偏低、凝沉性变强、透光率升高、冻融稳定性降低,同时采用红外光谱与差式扫描量热分析进行结构分析表征,证明糯米淀粉的阳离子化。

Abstract:

Glutinous rice was used as the material and 3-chloro-2- hydroxypropyl trimethyl ammonium chloride (CHPTMA) was used as etherification agent to prepare cationic starch under alkaline condition. Results showed the optimal condition was 50 ℃ of reaction temperature, 4 h of reaction time, 100:8.00 of glutinous rice starch and etherification agent ratio and 1.00:1.94 of etherification agent and NaOH ratio. Nitrogen content of glutinous rice starch was 0.370% and degree of substitution was 0.0613. Compared with original starch, cationic starch exhibited lower viscosity, stronger coagulation property, higher transmittance and lower frozen-thaw stability. Glutinous rice starch was characterized through analyses of infrared spectroscopy (IR) and differential scanning calorimetry (DSC).

Key words: cationic glutinous rice starch, preparation, property
