초록
The capacity of micelle formation between astaxanthin and various surfactants was compared. Tween 20 was identified the most suitable surfactant in terms of astaxanthin extraction capacity. The ethylene oxide group of Tween 20 was identified as the most significant factor to increase the HLB value that determined the extraction capacity. The effect of micelle formation condition, such as molar ratio of astaxanthin and Tween 20, pH and ionic strength was also investigated. pH and ionic strength showed no significant effects. Antioxidant activity of astaxanthin was twice of
