超声波辅助番茄皮渣中番茄红素在核桃油中的富集工艺

Enrichment of lycopene in walnut oil by ultrasonic assisted tomato peel

为优化番茄皮渣中番茄红素在核桃油中的富集工艺,在单因素试验的基础上,运用响应面分析法,研究料液比、超声富集时间、超声波输出功率对番茄红素得率的影响。建立番茄红素得率的二次回归方程,并确定超声波辅助核桃油富集番茄皮渣中番茄红素的最佳条件为:料液比1∶6(g/mL),超声波富集时间30 min,超声波输出功率200 W,对优化的工艺条件进行验证,番茄红素得率平均为152.52μg/g,核桃油中的番茄红素的含量为25.42μg/g。与理论值较为接近,RSD值为1.54%。

In order to optimize the enrichment technology of lycopene in walnut oil, the influence of material liquid ratio, ultrasonic enrichment time and ultrasonic power on Lycopene yield was studied based on single factor experiment and response surface methodology. The regression equation of yield of lycopene was established and the ultrasonic assisted walnut oil enrichment of lycopene from tomato peel was studied. The optimum conditions of the extraction were .- liquid ratio 1 ： 6 （g/mL）, ultrasonic enrichment time 30 min, ultrasonic power 200 W. The verification test showed that the average content of lycopene was 152.52 mg/g, the content of lycopene in walnut oil was 25.42 g/g, very close to the theoretical value, and the RSD is 1.54%.
