采用无水乙醇预处理番茄酱，用乙酸乙酯提取番茄红素，以番茄红素提取得率为考察指标，通过单因素和正交实验确定无水乙醇预处理最优条件为：预处理时间20 min、处理温度50℃、料液比1∶2、二级处理，番茄红素提取得率为62．45 mg／100 g，番茄红素含量可达80．69％。同时采用 SEM，IR，XRD现代仪器分析手段对番茄红素产品进行表征，结果表明无水乙醇预处理提取得到番茄红素产品表征与番茄红素标准品基本一致。

Lycopene is extracted by anhydrous ethanol pretreatment method with ethyl acetate as extraction solvent and lycopene extraction rate as index.The optimal conditions of anhydrous ethanol pretreatment are obtained through single factor and orthogonal experiments,and the results show that the anhydrous ethanol pretreatment processing time is of 20 min,the processing temperature of 50 ℃, and the solid-liquid ratio of 1 ∶ 2,the number of processing stage is 2.Under these conditions, lycopene extraction rate is up to 62.45 mg/100 g and lycopene content reaches 80.69%.The modern instrumental analysis methods such as SEM,IR and XRD are applied to characterize the product,and the results show that the characterization of lycopene product and pretreatment of anhydrous ethanol is basically in accordance with the lycopene standard.
