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。

Processing parameters for ultrasonic extraction of ethanol-soluble β-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 ...
