摘要： 比较研究了热提取、超声波提取、微波提取3种不同工艺对栀子黄色素提取效果的影响.热浸提正交试验的最佳工艺条件:70%的乙醇(体积分数,下同)提取1.5 h,提取温度30℃,料液比1:25(g:mL,下同),产品的色价为66.45.超声波提取正交试验的最佳工艺条件:80%的乙醇提取20 min,料液比1:20,产品的色价为87.77.微波提取单因素试验的最佳工艺条件:提取功率800 W,用50%乙醇提取30 min,提取温度50℃,料液比1:5,色价为64.14.结果表明:热浸提、超声波提取、微波提取3种方法提取栀子黄色素的色价明显不同,超声波提取的效果最好.

Abstract: The effects of extracting yellow pigment from Gardenia jasminoides Ellis by hot extraction, ultrasonic extraction and microwave-assisted extraction were compared. Orthogonal tests were used to optimize the conditions. Through orthogonal test of heat extraction, the optimum conditions were determined as follows:70% EtOH as extracting solvent, 2 h, 30℃, 1:25 solid-liquid ratio, the color value of the extracted pigment achieved 66.45.Through orthogonal test of ultrasonic extraction,the optimum conditions were determined as follows: 80% EtOH as extracting solvent,20 min at 20℃,and solid-liquid ratio 1:20, the color value of the extracted pigment achieved 87.77.Through single factor test of microwave-assisted extraction,the optimum conditions were determined as follows: 800 W, 50% EtOH as extracting solvent,30 min at 50℃,and solid-liquid ratio 1:5, the color value of the extracted pigment achieved 64.14. The results showed that the effects of extraction while by three different methods were different, ultrasonic extraction was the best way.
