| 摘 要： | 研究了茶多酚乙醇水溶液提取过程中各因素对提取率的影响，确定最优工艺条件为乙醇质量分数50%，溶剂用量7ml/g，提取温度60℃，提取时间35min。通过冷、热模放大实验得出，茶多酚提取为内扩散过程，按临界悬浮转速放大是比较理想的放大方法。

| Abstract: | The effects of different factors on the extraction of tea-polyphenols were studied by using mixed solvent composed of alcohol and water.The optimal conditions were mass percentage of alcohol 50%,solvent 7 ml/g,extracting temperature 60℃,and extracting time 35 min.The results show that the process is controlled by interior diffusion and critical suspension speed is an ideal magnification method. |
