The solubilities of glucose were measured in saturated alkali metal halide aqueous solutions at 30℃. The solubilities of glucose in saturated sodium halide aqueous solutions were as same as or lower than that in water. On the contrary, the solubilities of glucose in saturated potassium halide aqueous solutions were higher than that in water. The determinations of solubilities of glucose, galactose and xylose were also carried out in the presence of NaCl/KCl at 30℃. These electrolytes have effects on sugar solubilities. The effects have varieties that depends on combinations of sugars and electrolytes, electrolytes concentrations. Sodium ion has both salting-out and salting-in effects. Potassium ion has only a salting-out effect.
