摘要
为了获得非晶态的葛根淀粉颗粒,以乙醇为保护剂,考察了乙醇体积分数、料液比、非晶化处理温度及时间对葛粉非晶化的影响,用偏光显微镜观测处理后的淀粉颗粒结构。结果表明:当乙醇体积分数为50%,料液比为1︰4 (g/mL)时,在80℃条件下反应15 min,可以制备出质量较好的非晶颗粒态葛根淀粉。
To optimize the preparation process of non-crystal granular pueraria starch, the effects of concentration of ethanol,solid-liquid ratio, reaction temperature and reaction time were studied. The treated starch particles structure was observed by the polarimicroscope. The results showed that the optimum reaction conditions were as followed: the reaction solvent was50% ethanol solution, the solid-liquid ratio was 1︰4(g/mL), the reaction time was 15 min and temperature was 80 ℃. at this condition, high quality non-crystal granular pueraria starch could be obtained.
