Egg Yolk Lecithin
1. Brief Introduction:
Egg yolk lecithin is a phospholipid mixture, the main component of which is phosphatidylcholine (PC), this product is milky white or light yellow powder or waxy solid, with a slight special odor and a slightly greasy feel when touched. It is soluble in ethanol, ether, chloroform or petroleum ether (boiling range: 40℃~60℃), and is almost insoluble in acetone and water. It is very sensitive to heat and is easily hydrolyzed under the action of acid, alkaline and esterase.
Egg yolk lecithin is mainly used as an emulsifier and solubilizer, liposome membrane material, etc. According to most reports, phosphatidylcholine can inhibit serum triglycerides and total cholesterol, and increase high-density lipoprotein.
2. Pharma Grade Egg Yolk Lecithin (Conventional Type):
Our refined egg yolk lecithin is a yellow or light yellow waxy product made from egg yolk powdery phospholipids through ethanol extraction and other processes using original patented equipment (ZL2017.20049599.7; ZL2010.20147413.X). Due to its strong antioxidant capacity and unique surface activity and physiological properties, it is widely used in the fields of medicine, nutrition and cosmetics.
