Purification method of lactonic sophorolipid

摘要

The present invention relates to a method for purifying a lactone-type sophorolipid, and more particularly, recovering the oxidized and lactone-type sophorolipid precipitates produced by culturing a yeast of the genus Candida having a sophorolipid-producing ability, and therefrom It relates to a method of purifying lactone-type sophorolipids with high purity through ultrafiltration using the principle of forming a micelle structure among the surfactant properties of sophorolipids.
