摘　　要：以浸出棉籽混合油为原料,采用稀酸水化脱胶、碱炼脱酸的混合油精炼工艺,考察了混合油精炼过程中混合油浓度、水化温度、水化时间、碱炼温度、碱炼时间对成品棉籽油磷脂含量和精炼得率的影响。结果表明:最佳工艺条件为混合油浓度80%、水化温度45℃、水化时间30 min、碱炼温度50℃、碱炼时间60 min,在最佳条件下,棉籽油精炼得率90.9%,色泽Y35 R4.2(133.4 mm槽),酸值(KOH)0.14 mg/g,磷脂含量69 mg/kg。The extracted cottonseed miscella was refined by degumming with diluted phosphoric acid solu- tion and deacidification with alkali solution, and the effects of miscella concentration, hydration tempera- ture, hydration time, alkali refining temperature and alkali refining time on phospholipid content and refi- ning yield of cottenseed oil were investigated. The results showed that the optimal process conditions were obtained as follows ： miscella concentration 80%, hydration temperature 45 ℃, hydration time 30 min, alkali refining temperature 50 ℃ and alkali refining time 60 min. Under these conditions, the refining yield, color, acid value and phospholipid content of cottonseed oil were 90.9%, Y35 R4.2（ 133.4 mm groove）, 0.14 mgKOH/g and 69 mg/kg, respectively.
