PROCESS FOR PREPARING THE STABILIZED ASTAXANTHINE BY LIPOSOMAL ENCAPSULATION

摘要

The present invention relates to a method for extracting astaxanthine from microalgae by using supercritical carbon dioxide and a method for stabilizing the same. More specifically, the method of the present invention comprises the steps of: extracting astaxanthine by applying supercritical carbon dioxide to crushed microalgae raw material under conditions of 35-90°C and 300-800 bar; and separating and recycling carbon dioxide from the extracted astaxanthine and a mixture of supercritical carbon dioxide. The extracted astaxanthine has less degradation factor such as lipid oxidation even for a long-term storage by being stabilized through liposome encapsulation; thereby has excellent stability and color as an antioxidant matter for raw materials of cosmetics.
