以提取卵磷脂(PC)后的大豆粉末磷脂为原料,以碱性乙醇为溶剂提取磷脂酰乙醇胺(PE),并进行冷冻纯化。在单因素实验的基础上,以PE得率为指标,响应面优化实验确定了PE的最佳提取条件为:提取温度45℃,料液比1:20,乙醇碱浓度V(无水乙醇):V(25%氨水)=100:2,提取时间50 min,提取次数2次。在最佳条件下,PE 得率为79.53%,含量为48.42%;当冷冻温度为-15℃,冷冻时间为8 h时,PE含量提升到72.73%,得率为66.71%。
以提取卵燐脂(PC)後的大豆粉末燐脂為原料,以堿性乙醇為溶劑提取燐脂酰乙醇胺(PE),併進行冷凍純化。在單因素實驗的基礎上,以PE得率為指標,響應麵優化實驗確定瞭PE的最佳提取條件為:提取溫度45℃,料液比1:20,乙醇堿濃度V(無水乙醇):V(25%氨水)=100:2,提取時間50 min,提取次數2次。在最佳條件下,PE 得率為79.53%,含量為48.42%;噹冷凍溫度為-15℃,冷凍時間為8 h時,PE含量提升到72.73%,得率為66.71%。

With soybean phospholipids powder as raw material, in which phosphatidylcholine was extrac-ted, phosphatidylethanolamine ( PE ) was extracted by alkaline ethanol and purified by freezing. With yield of PE as the indicator, based on the single factor experiment, the optimal extraction conditions of PE were obtained by response surface methodology as follows:extraction temperature 45℃, solid-liquid ratio 1:20,concentration of alkaline ethanol 2. 00 mL of 25% ammonia per 100 mL ethanol, extraction time 50 min and extraction times twice. Under these conditions, the yield and content of PE were 79. 53% and 48. 42% respectively. Meanwhile, under the conditions of freezing temperature -15℃and freezing time 8 h, the content of PE improved to 72. 73% and the yield was 66. 71%.
