6种溶剂浸提番茄红素的比较研究

摘要

Using different extraction time, ratio of solid to liquid and temperature effect of three factors on lycopene in tomato powder by leaching test, results showed that： from the extraction yield, with chloroform and benzene is highest; from the ex- traction time, 5 hours before the lycopene yield increases, after a decline; from solid to liquid ratio, lycopene yield with sol- id -liquid ratio rises, the fastest rising is chloroform and benzene; from the extraction process stability, on the time factor and in the ratio of solid to liquid hexane on all showed strong fluctuation; in practice due to the temperature difference, part of the solvent with strong volatile, so the measured data the lack of accuracy.%采用不同浸提时间、固液比和温度3个影响因子对番茄粉末中番茄红素进行了浸提试验，结果表明：从浸提收率看，用氯仿和苯最高；从浸提时间看，5h前番茄红素收率上升，之后下降；从固液比看，番茄红素收率随固液比上升而上升，上升最快的是氯仿和苯；从萃取过程稳定性上看，在时间因素和固液比上正己烷均表现为较强的波动；在实际操作中因温度的不同，部分溶剂有较强挥发，故测得数据缺乏准确性。
