摘要: 用超声波强化溶剂提取法从胡萝卜中提取醇溶性β-胡萝卜素,利用响应曲面法对提取工艺参数进行优化研究。通过典型性分析得出最优工艺为:提取液固比30:1(V:m),提取时间45min,提取超声功率40%,提取温度35℃。在此条件下提取理论β-胡萝卜素含量达到1.6371mg/g,验证实验条件下实际最大值1.6230mg/g。超声波强化提取具有提取时间短、收率高、无需加热的特点,开辟了β-胡萝卜素提取的新途径。

Abstract: Processing parameters for ultrasonic extraction of ethanol-solubleβ-carotene were optimized by the response surface method. Results showed that the optimum parameters are as follows: ratio of solution-solid 30:1(V:m), time 45 min, power of ultrasonic 40% and temperature 35 ℃. On these conditions, the theoretic extraction rate is 1.6371 mg/g, and the practical extraction rate is 1.6230 mg/g. Ultrasonic extraction method has the characteristics of short extraction time, high extraction rate and no heating, which develops a new approach for extraction of β-carotene.
