摘要
采用乙酸乙酯从番茄皮渣中提取番茄红素并结合紫外分光光度法测定其含量。在单因素试验的基础上,利用响应曲面法优化了提取工艺,建立了浸提温度、浸提时间、液固比与提取率之间的数学模型,确定了番茄红素提取的最佳工艺条件,即以乙酸乙酯为浸提溶剂、浸提温度51℃、浸提时间2.3h、液固比8.9:1(V/g),在此最佳工艺条件下进行提取,番茄红素提取率为(28.74±0.05)%(n=3)。
In this study,extraction technology of lycopene from tomato peel was optimized.Acetic ether was chosen as extraction solvent and UV analysis was used to determine the content.The mathematical-regression model was established about the dependent variable(the extraction yield of lycopene) and independent variables(ratio of liquid to solid,extraction temperature,extraction time).According to this model,the optimum technological conditions were as follows:acetic ether as the extraction solvent,extraction temperature 51℃,extraction time 2.3 h,ratio of liquid to solid 8.9:1.Under the conditions,the lycopene yield was(28.74±0.05)%(n=3).
