Abstract
A method for decolorization and deodorization of egg yolk oil comprises at least: adding a first ether solution to a crude egg yolk oil, and performing a first stirring process, to produce a first egg yolk oil mixture; adding activated carbon to the first egg yolk oil mixture, performing a second stirring process, and removing the activated carbon, to produce a second egg yolk oil mixture; adding a second ether solution and distilled water to the second egg yolk oil mixture, and performing a third stirring process, to produce a third egg yolk oil mixture; and removing distilled water, part of the first ether solution, and part of the second ether solution from the third egg yolk oil mixture by a distillation process, and removing the remaining first ether solution and the remaining second ether solution by a vacuum process to produce a decolorized and deodorized egg yolk oil.
