In the step of dehydration, fructose-containing liquid sugar is brought in the presence of an organic solvent exhibiting azeotropic behavior with respect to water, in contact with a stream of gas causing no denaturation of fructose-containing sugar to remove moisture contained therein. The fructose-containing liquid sugar obtained from said step of dehydration is subject to seed crystal addition treatment in the following step of aging. Lastly, the aged fructose-containing sugar obtained from said step of aging is introduced into anhydrous alcohol for solidification. | |
