PROBLEM TO BE SOLVED: To prevent the deterioration of the properties of capsule particles and to improve the storage stability of a water-soluble organic substance and water by removing water in the capsule particles by making an extracting solution containing a compound same with or the same kind of the organic substance contact the capsule particles containing water and the organic substance. SOLUTION: Capsule particles containing water and water-soluble organic substance using saccharides such as glucose, galactose, fructose, and mannose, a polyol such as glycerine, sorbitol, ethylene glycol, polyethylene glycol, propylene glycol, and polypropylene glycol, a water-soluble polymer such as sodium polyacrylate, polyethyleneimine, and polyvinyl alcohol, and others are brought into contact with an extracting solution containing a compound same with or of the same kind of the water-soluble organic substance to remove water in the particles. |
