| 摘 要： | 为了从大豆油脚中提取大豆卵磷脂，通过真空浓缩、丙酮脱油、乙醇提取、吸附脱色、过滤、浓缩等工艺对提取条件做了系统实验，实验结果表明，丙酮的脱油温度和时间，乙醇的提取温度和时间以及吸附剂的选择是影响提取效率的主要因素。用最佳工艺提取得到了纯度为82％的大豆卵磷脂。

| Abstract: | The effect of temperature, time and absorbant on the extractability of soybean lecithin was studied in order to obtain the pure soybean lecithin. Crude soybean lecithin was extracted by condensation in vacuum, removal oil with acetone and purification with ethanol by means of soybean bottom oil. The results show that the extracting efficiency of soybean lecithin is effected by temperature, time and absorbant. The soybean lecithin with purity 82% was prepared by the best art. |
