摘要
为优化牛奶中雌二醇的微波提取工艺,在单因素实验的基础上,利用响应曲面法考察液料比、微波功率和微波时间对雌二醇提取率的影响,优化提取工艺。结果表明:牛奶中雌二醇微波提取的优化工艺条件为:液料比4.1∶1,微波功率475 W,微波时间61 s。在此条件下,雌二醇的最高提取率为92.77%。与超声提取方法相比,微波提取工艺具有提取时间短,得率高,能耗低,环保等优点。
The extraction process of estradiol from milk was investigated in this paper. Based on single factor experiments,response surface methodology was used to explore the effects of liquid-material ratio,microwave power and microwave time on extraction yield of estradiol. The results showed that the optimal conditions for the extraction of estradiol were the liquid-material ratio of 4.1∶1,microwave power of 475 W,microwave time of61 s. Under the optimal extraction conditions,the highest extraction rate of estradiol was up to 92.77%. Compared with the ultrasonic extraction method,microwave extraction method had short extraction time,high extraction yield,low energy consumption,environmental protection and other advantages.
