Abstract
The present invention relates to a method for preparing anhydrous sugar alcohol, and more particularly, to a cheap and highly efficient method for preparing anhydrous sugar alcohol having a high final purity of at least 99%, and having good ion content, pH, conductivity, and color properties. According to the method, a hydrogenated sugar is dehydrated so as to be transformed into anhydrous sugar alcohol, and a series of processes including distillation, crystallization, decoloration, and ion exchange resin treatment are conducted.
