| 摘 要： | 以酿酒后同一批次葡萄籽为原料,采用索氏法、微波辅助法、超声波辅助法、超临界CO2萃取4种方法提取葡萄籽油。分别从提取率、油品理化性质、脂肪酸组分及含量方面对4种提取方法进行比较。结果表明,不同提取方法对葡萄籽油各脂肪酸组分、含量及提取率均有不同程度的影响,采用微波辅助提取率最高,达16.85%;采用超临界CO2萃取的葡萄籽油理化指标均优于其它方法;其中超临界CO2萃取的葡萄籽油亚油酸含量最高,达70.54%。

| Abstract: | Using the same batch of grape seeds as the materials,the grape seeds oil was extracted by four methods:Soxhlet extraction,MicroWave-assisted extraction,Ultrasonic extraction and Supercritical carbon dioxide extraction(SCF-CO2).The extraction rate,physical and chemical indices and fatty acid contents were compared.The results showed that MicroWave-assisted extraction had the hightest oil yields reached 16.85%;the SCF-CO2 extracted oil excelled the other oil in physiochemical properties;different extraction m... |
