摘　　要：通过响应面法分析优化微波辅助提取甘蔗糖厂滤泥中叶绿素的工艺条件,并与传统溶剂法进行比较分析。结果表明微波辅助提取滤泥中叶绿素的最佳工艺条件为:微波辐射时间60s,提取温度34℃,液料比7:1(mL/g),最大提取量预测值为0.280mg/g,实测值为0.277mg/g,叶绿素提取量比传统工艺高出6.95%,且提取时间大大减少。Response surface analysis was used for optimizing the microwave-assisted extraction of chlorophyll from filter mud in sugar cane mill factories.The results showed that the optimal conditions for microwave-assisted extraction of chlorophyll were microwave irradiation time of 60 s,extraction temperature of 34 ℃ and material-to-liquid ratio of 1：7（g/mL）.Under these conditions,the predicted chlorophyll yield was 0.280 mg/g,which was close to the actual chlorophyll yield of 0.277 mg/g.Compared with the traditional extraction,microwave-assisted extraction revealed an enhanced yield of chlorophyll by 6.95% with considerably time-saving benefits.
