| 摘 要： | 采用离心脱水、冷冻、异丙醇、无水乙醇处理等方法对西瓜浆样进行预处理,考察了各预处理方法对番茄红素提取的影响。结果表明:从西瓜浆样中提取番茄红素的最佳处理条件为西瓜浆样离心脱水或冷冻预处理,以石油醚∶丙酮(1∶1)为提取溶剂、料液比为1∶5、提取时间为20 min、提取温度为45℃,西瓜经离心脱水处理或冷冻处理后,可缩短提取时间、降低料液比,且在提取过程中受提取温度影响较小。

| Abstract: | The watermelon paste was pre-treated by centrifugal dehydration,frozen,isopropanol treatment,and ethanol treatment.The effect of pre-treatment method on lycopene extraction was studied.The results showed that the optimum lycopene extraction conditions from watermelon were as follows: the watermelon paste was pre-treated by centrifugal dehydration or frozen,extraction solvent was petroleum ether plus acetone(1∶1),ratio of material to liquid was 1∶5,extraction time was 20 minutes,and extraction temperature was 45 ℃. |
