    • A process for obtaining yolk lecithin from a raw egg yolk which comprises subjecting a raw egg yolk to extraction with liquid dimethyl ether to obtain an extract and dehydrating the extract to an extent that the water content is not more than 20% by weight, whereby a lecithin-rich fraction is obtained as a separate phase from a neutral lipids-fraction. The isolated lecithin-rich fraction may further be subjected to a second-stage dehydration to give a product in which the lecithin content is as high as 50 to 85% by weight and the water content is very small, for example, below 2 to nearly 0% by weight. By the process of the present invention, there can be obtained a high quality lecithin in high yield.
    • 一种从生蛋黄中获得卵黄卵磷脂的方法,其特征在于,将生蛋黄用液体二甲醚萃取,得到提取物,使提取物脱水到含水率不超过20重量%的程度, 获得富含卵磷脂的级分作为与中性脂质组分分离的相。 分离的富含卵磷脂的级分可以进一步进行第二级脱水,得到卵磷脂含量高达50〜85%(重量),含水量非常小的产品,例如低于2〜几乎 0重量%。 通过本发明的方法,可以高产率获得高质量的卵磷脂。
