摘 要:通过单因素试验和响应面分析法优化了超声波-混合溶剂法提取万寿菊中类胡萝卜素的工艺方法,探讨了不同提取剂及比例、料液比、提取功率、提取时间及温度对提取效果的影响。结果表明,超声波-混合溶剂法提取万寿菊中类胡萝卜素的最佳条件:理想的提取剂为乙酸乙酯:石油醚=3:2(v/v),料液比1:20(g/mL),超声功率450 W,超声时间35 min,温度39.5℃。在此条件下,类胡萝卜素的提取得率可达到26.78 mg/g,其含量较常规的浸取法高22.8%。The optimum conditions of ultrasound-mixed solvent extraction for carotenes in Marigold were determined by the single factor experiment and the response surface analysis. The effects of different proportion mixed solvents, ratio of material to liquid, ultrasonic power, ultrasonic time and temperature were explored. The results showed that the optimum extraction conditions were that acetic ether:petroleum ether=3:2 (v/v) as the best extraction solvents, the liquid solid ratio of 20 to 1, ultrasonic power 450 W, extraction time 35 minutes and temperature 39.5 ℃. Under these conditions, the extraction rate for carotenes reached 26.78 mg/g. The proportion of carotenes ultrasound-mixed solvent extraction was 22.8% higher than that by the traditional process.
