超声波辅助法提取番茄红素的条件优化

目的]优化超声波辅助提取番茄红素的工艺条件。方法]在单因素试验基础上,以提取溶剂、提取时间、提取温度、超声功率4个因素进行正交试验。结果]超声波提取番茄红素的最优条件：以乙酸乙酯作提取溶剂,提取温度45℃,提取时间6 m in,超声功率120W,0.5%蔗糖为添加剂。在此最优提取条件下,番茄红素含量可达4.22 mg/m l,优化效果明显。结论]为进一步开发利用番茄红素奠定了基础。

Study on the Optimization of Ultrasonic on Lycopene Extraction

Objective] The aim was to optimize the crafts conditions of using ultrasonic to extract lycopene.Method] Based on the single factor test,the orthogonal design was conducted by taking resolution,extracting time,temperature and ultrasonic power.Result] The optimum extraction technology of lycopene was as follow: taking ethyl acetate as extractant,reaction temperature of 45 ℃,reaction time of 6 min,ultrasonic power of 100 W with 0.5% saccharose added.Under the optimal extraction condition,the lycopene content was 4.22 mg/ml,and the optimization effect was distinct.Conclusion]This study laid a foundation for more exploitation of lycopene.
