Abstract:
PURPOSE: To provide an extraction method to obtain productively and economically a yolk oil containing large quantities of phospholipid and vitamin E by immersing a semidry yolk in ethanol, removing the ethanol, and squeezing the oil under pressure.
CONSTITUTION: A dry yolk with a moisture content of 35% or less is immersed in 40% or more of ethanol based on the weight of the yolk for 15min or more.
