| 摘 要： | 以NaHSO3和NaNO2为酯化剂,采用水相法制备了低取代度的淀粉硫酸酯(SSE),测定了SSE糊的冻融稳定性、凝沉性能、透明度、黏度；利用红外光谱仪分析了产物的化学结构.结果表明,酯化的SSE糊的透光率比淀粉的提高22.4％,透明度稳定性明显增强；SSE糊的黏度冷热差值均比淀粉的低,抗老化性能增强、凝沉性能得以改善,...

| Abstract: | Starch sulfate ester(SSE) with a low degree of substitution was synthesized from cassava starch in aqueous solution in the presence of NaHSO3 and NaNO2 as the esterification agents.The freeze-thaw stability,anti-aging capacity,transparency and viscosity of as-synthesized SSE paste were determined,and its chemical structure was analyzed by means of infrared spectrometry(IR).Results show that after esterification,the transparency of the SSE paste was increased by 22.4%,and its transparency stability was enhan... |
