Process for producing high-purity erythritol crystal |
| abstract |
A process for producing a high-purity erythritol crystal comprising a crystallization step of subjecting an erythritol-containing aqueous solution as a raw solution to crystallization, wherein an erythritol concentration of said erythritol-containing aqueous solution is adjusted to 30 to 60% by weight at the beginning of the crystallization step; said erythritol-containing aqueous solution is cooled at a cooling rate of not more than 20 DEG C./hour; a seed crystal of erythritol is added to said erythritol-containing aqueous solution in the course of the cooling, and the solution is cooled to not more than 20 DEG C. Such a process for producing a high-purity erythritol crystal of the present invention has a still higher purity and is further improved in crystal shape as compared to those produced by conventional processes. |
