超声微波协同萃取(UMAE)番茄中番茄红素的研究

Study on the Extraction of Lycopene from Tomatoes by Ultrasonic/Microwave Assisted Extraction(UMAE)

研究了超声微波协同萃取番茄中的番茄红素。以乙酸乙酯为萃取溶剂并以不同的提取时间、微波功率和液固比作为参数进行实验,并进行了工艺优化。在提取时间367 s、微波功率98 W和液固比10.6∶1的条件下实际提取率可达到97.4%。实验结果表明:UMAE法是一种能够快速有效的提取番茄红素的方法。

Ultrasonic/microwave assisted extraction （UMAE） of lycopene from tomatoes was studied. The optimization experiment with ethyl acetate as solvent was carried out by three variables as following：extraction time, microwave power and solvent to solid ratio. The optimal conditions for UMAE were microwave power,98 W; the ratio of solvents to tomato paste, 10.6：1 （V/W） ; extracting time, 367 s. Under these conditions, the yield of lycopene was 97.4% , implying that UMAE was an attractive lycopene extracting method with fast speed and high efficiency.
