The Study on Extraction of Egg Yolk Lecithin

Qu Huai-kun (The Technology College of Linyi,Linyi,Shandong,276000)  
To explore the method of extracted egg yolk lecithin from the egg yolk.Experiment with egg yolk as raw material,used organic solvent and enzyme method to extract from the egg yolks,then respectively lecithin crude products by silica gel column chromatography and metal ion precipitation purification products,through determination get lecithin the phosphorus content,judge its permix purity level.The results showed: The organic solvent method get egg yolk lecithin crude products and then by silica gel column chromatography purification for high purity egg yolk lecithin high-quality goods,must rate for the phosphorus content for 8.38%,lecithin 15.33%.Is a kind of high efficient and economic yolk lecithin extraction method.
