Optimization of Microwave Assisted Extraction of Hami Melon Seed Oil by Response Surface Methodology
Response surface methodology was used to optimize the microwave-assisted extraction process of Ha-mi melon seed oil.The effects of solvent type,liquid-solid ratio,extraction time,extraction temperature and micro-wave power on the extraction rate of Hami melon seed oil were investigated.The results indicated that the average ex-traction rate of Hami melon seed oil was 81.88％with the liquid-solid ratio of 10∶1,extraction temperature of 46 ℃ and microwave power of 520 W,close to the predicted value.According to the meteorological mass spectrometry,there were 13 kinds of fatty acids in Hami melon seed oil,including linoleic acid,oleic acid,palmitic acid and stear-ic acid,etc.In addition,compared with four common vegetable oils,it could be concluded that Hami melon seed oil had a great potential as edible oil,and contained rich fatty acids and high nutritional value.
