【摘要】 研究了以姜黄为原料,用95%的食用乙醇作溶剂,在超声场的介入下对姜黄色素提取率的影响。试验结果表明:超声场的介入有利于姜黄色素的提取;通过均匀试验设计确定了最佳提取工艺条件:超声功率90%、超声时间75min、超声温度50℃,在此条件下姜黄色素的提取率可达85%。对比试验结果显示:超声场介入的最佳提取工艺比传统提取工艺提高35%。更多还原

【Abstract】 The effect of ultrasound field on extracting yield of curcumin was studied during the course ofextracting curcumin by 95% edible alcohol. Optimum condition of enhancing extraction of curcumin byultrasound field was obtained from homogeneous test. A yield of 85% curcumin can be obtained under this optimum condition. The yield of extraction is 35% than the traditional method.更多还原
