摘要
实验探索超声波辅助提取鹌鹑蛋黄卵磷脂的工艺条件,考察溶剂组成、溶剂用量、提取时间及提取次数等因素对提取效果的影响,通过正交试验考察主要因素间的交互作用并优化工艺条件。结果表明,最佳工艺条件为:乙醇:乙醚=2:1,溶剂用量为4倍蛋黄体积,提取时间30min,提取2次,提取率达87.5%,卵磷脂纯度70.3%。该法操作简单、提取率高、溶剂残留少,为提取鹌鹑蛋黄卵磷脂的可行方法。
In this paper, the technological condition of extracting lecithin from quail＇ s egg yolk aided with ultrasonic was researched. The effect of such factors as solvent component and amount, time and degree on extraction efficiency was studied, and orthogonal test was made to research reciprocity among primary factors and to optimize technological condition. The results showed that the optimum conditions were： the ratio of ethanol to aether 2：1, using 4 times solvent as much as egg yolk volume, extracting 30min, and repeating once above-mentioned operation, on this conditions the yield reached 87.5% and the purity of product was 70.3%. This method was charactered with convenient, great efficiency and little solvent leavings. So it is feasible to extract lecithin from quail＇ s egg yolk.
