摘要
采用响应面优化微波辅助提取哈密瓜籽油工艺,考察了单因素溶剂种类、液料比、提取时间、提取温度、微波功率对哈密瓜籽油提取率的影响.结果表明:液料比为10∶1、提取温度为46℃、微波功率为520 W,得出哈密瓜籽油的平均提取率为81.88％,与预测值较为接近.并且通过气相色谱-质谱法分析出哈密瓜籽油中含有13种脂肪酸,其中主要的是亚油酸、油酸、棕榈酸、硬脂酸等.另外,经过与4种常见植物油对比,可以总结出哈密瓜籽油作为食用油的潜力巨大,并且含有的脂肪酸丰富,营养价值较高.
Abstract
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.
