摘要
使用乙酸乙酯为提取剂,对番茄中番茄红素的提取工艺进行了研究。在单因素实验基础上,选取提取时间、提取温度和料液比三个因素为自变量,采用正交设计,得到的最佳条件为:提取时间1.5 h,提取温度60℃,料液比为1∶4(g/V),在此条件下番茄红素提取率达到9.12μg/g;番茄红素对羟基自由基,超氧阴离子自由基具有较强的清除作用,而且有显著的剂量-效应关系。
Ethyl acetate as the extraction agent, extraction process of lycopene in tomato was studied. Three extraction parameters including extraction time, extraction temperature and solid-liquid ratio were optimized using orthogonal design. The optimum conditions were： extraction time of 1.5 h, extraction temperature 60 ℃, solid-liquid ratio of 1：4 （g/V）. Under these conditions, the extraction rate of Lycopene was 9.12 μg/g. The lycopene played a important role in eliminating hydroxyl radical and superoxide anion radical and has a significant dose - response relationship.
