Title:
結晶タガトースの製造方法
Document Type and Number:
Japanese Patent JP4712166
Kind Code:
B2
Abstract:
The present invention provides a method for producing tagatose crystals from an aqueous system using no organic solvent. In this method, seed crystals of tagatose are added to a tagatose solution in which a tagatose purity of solid contents in the solution is at least 70% and a solid contents concentration in the solution is 60 to 98 mass%, and crystallization of tagatose is carried out by stirring and cooling the solution while keeping a degree of super saturation of tagatose at 1.25 or lower. It is preferred that the solution containing tagatose is a solution containing no organic solvent. It is further preferred that a part of massecuite for which the crystallization is completed is added to a mother liquor so as to produce the tagatose crystals semi-continuously or continuously. It is furthermore preferred that the tagatose crystals formed from the massecuite are separated by centrifugation or filtration and dried to obtain tagatose crystals.
