  • Method for improving conversion rate of oil soluble unsaturated lipids into water-soluble lipids
    Patent number: 7456304
    Abstract: Disclosed relates to a method for improving a conversion rate of oil soluble unsaturated lipids into water-soluble lipids and, more particularly, to a method for improving a conversion rate of oil soluble unsaturated lipids into water-soluble lipids that forms an unsaturated lipid-chloride derivative having an increased reaction activity by using a pyridine-thionyl chloride as a catalyst, not directly causing a reaction between the unsaturated lipids and amino acids, or that applies an emulsifier to cause a reaction between the unsaturated lipids and amino acids so as to minimize the size of lipid particles to a nano-size of less than 50 nm, thus improving the reaction conversion rate to more than 99%.
