摘　　要：以文冠果仁为研究材料,对比不同提取方法下文冠果油脂的提取率、理化性质及油脂中脂肪酸组成,同时综合成本、能耗等因素,最终确立亚临界萃取法为绿色、高效率、低成本的文冠果油脂提取方案。结果表明,采用亚临界萃取法提取的文冠果油中酸值最低仅为0.34。采用不同方法提取的文冠果油均检测出10种脂肪酸,其中,采用亚临界萃取法提取的文冠果油中神经酸含量最高为3.29%。进一步通过单因素试验研究萃取温度、萃取时间、萃取压力、萃取次数对亚临界萃取法提取油脂提取率的影响,确定亚临界萃取法提取文冠果油最优工艺参数为:萃取温度为45℃,萃取压力为1.1 MPa,萃取时间为40 min,萃取次数为2次,文冠果油提取率为96.7%。Taking Xanthoceras sorbifolia kernel as the research material,the extraction rate,physical and chemical properties and fatty acid composition of Xanthoceras sorbifolia oil were compared under different extraction methods,finally,the subcritical extraction method was established as a green,high-efficiency and low-cost extraction scheme of Xanthoceras sorbifolia oil.The results showed that the acid value of Xanthoceras sorbifolia oil extracted by subcritical extraction was only 0.34.Ten kinds of fatty acids were detected in Xanthoceras sorbifolia oil extracted by different methods,among which the content of neural acid in Xanthoceras sorbifolia oil extracted by sub-critical extraction was the highest(3.29%).The effects of extraction temperature,extraction time,extraction pressure and extraction times on the extraction yield of oil by subcritical extraction were studied by single factor experiment,the optimum extraction parameters of Xanthoceras sorbifolia oil were determined as follows:extraction temperature 45℃,Extraction Pressure 1.1 MPa,extraction time 40 min,Extraction Times 2,extraction rate 96.7%.
