| 中文摘要: |
| 以文冠果籽为原料，探讨糖效应辅助水剂法提取文冠果籽油的最优工艺条件，并对其脂肪酸组成及理化特性进行分析。以提油率为考察指标，通过单因素试验确定蔗糖浓度、液料比、提取温度及提取时间对文冠果籽提油率的影响，采用响应面中心组合试验设计优化提油工艺条件。结果表明，糖效应辅助水剂法提取文冠果籽油的最优工艺条件为：蔗糖浓度1.2 mol/L，液料比5.4∶1，提取温度64℃，提取时间210 min。在最优工艺条件下，文冠果籽提油率为70.9%；所得文冠果籽油色泽亮黄，澄清透明，不饱和脂肪酸含量高达92.86%，酸值和过氧化值等理化指标均符合GB 2716—2005《食用植物油卫生标准》。 |

| With Xanthoceras sorbifolia seed as raw material，the optimal process conditions of sugar effect-assisted aqueous extraction of Xanthoceras sorbifolia seed oil were investigated and the fatty acid composition and physicochemical properties of the oil were analyzed.With oil extraction rate as index，the effects of sucrose concentration，ratio of liquid to material，extraction temperature and extraction time were studied by single factor experiment, and the oil extraction process conditions were optimized by response surface central composite design experiment. The results showed that the optimal conditions of sugar effect-assisted aqueous extraction of Xanthoceras sorbifolia seed oil were obtained as follows：sucrose concentration 1.2 mol/L，ratio of liquid to material 5.4∶1, extraction temperature 64℃ and extraction time 210 min.Under these conditions，the oil extraction rate reached 70.9%.The Xanthoceras sorbifolia seed oil obtained was bright yellow and transparent.The content of unsaturated fatty acids was 92.86%，and its physicochemical indexes such as acid value and peroxide value met the requirement of GB 2716—2005. |
