摘要
以番木瓜籽为原料,对2种提取番木瓜籽油的工艺和效果进行比较。通过正交试验得到溶剂法提取番木瓜籽油的最佳工艺条件为:溶剂选用石油醚,料液比1∶8(g∶m L),提取时间2 h,提取温度80℃,番木瓜籽油提取率为35.8%;超声波辅助法提取番木瓜籽油的最佳工艺条件为:溶剂选用石油醚,料液比1∶4(g∶m L),超声温度50℃,超声时间20 min,超声功率120 W,番木瓜籽油提取率为38.8%。结果表明,超声波辅助法提取的番木瓜籽油得率比溶剂法高,并且超声波辅助法比溶剂法提取的时间短、温度低,是一种短时高效的提取方法。
The oil extraction from papaya seed by different methods was studied. The optimum conditions for solvent extraction are solvent petroleum ether, extraction temperature 80℃ ,time 2 h, ratio of material to liquid 1：8 （g： mL） ,the extraction rate is up to 35.8%. The optimum conditions for ultrasonic assisted extraction are solvent petroleum ether, extraction temperature 50℃, 120 W ultrasonic treating for 20 min, ratio of material to liquid 1 ： 4 （g： mL） ,the extraction rate is up to 38.8%. It is revealed that the ultrasonic assisted extraction is superior with advantages of lower temperature, short time and higher extraction rate.
