中文摘要：以番木瓜籽为原料,通过单因素试验和响应面优化试验研究了浸提溶剂、料液比、浸提温度、浸提时间等因素对番木瓜籽油提取率的影响,确定了溶剂浸提番木瓜籽油的最佳工艺条件,并分析了番木瓜籽油的理化性质和脂肪酸组成。结果表明:正己烷浸提法提取番木瓜籽油的浸提温度为61℃、浸提时间为2.5 h和液料比为3.18∶1(mL∶g)。在该条件下油脂提取率为21.27%;番木瓜籽油的酸值、过氧化值等指标达到了食用油脂的标准,但是其杂质含量较高,还需进一步精炼;番木瓜籽油中含有5种脂肪酸,主要是棕榈酸(18.90%)、油酸(71.06%)和亚油酸(4.28%)。

外文摘要：Taking papaya seeds as raw material,single-factor tests and response surface experimental design were applied to study the effects of solvent/material ratio,extraction temperature and time on the extraction rate of papaya seed oil,and to optimize the extraction parameters.The physical and chemical properties of papaya seed oil were analyzed and fatty acid composition was determined by gas chromatography-mass spectrograph（GC-MS）.Results：The optimal parameters of extracting papaya seed oil are using hexane as solvent,solvent/material ratio 3.18∶1（mL∶g）,extraction temperature 61 ℃,and time 2.5 h.Under these conditions,the extraction rate reaches 21.27%.The acid value and peroxide value of the produced papaya seed oil meet the standard for edible oils and fats,but the impurity content is high,so further refine is needed.The papaya seed oil is composed of five fatty acids,mainly palmitic acid（18.90%）,oleic acid（71.06%） and linoleic acid（4.28%）.
