Verfahren zur Herstellung von alpha-L-Aspartyl-L-phenylalaninmethylester mit verbesserter Löslichkeit.

摘要

A process for producing dry alpha -L-aspartyl-L-phenylalanine methyl ester having an improved solubility by drying wet crystals of alpha -L-aspartyl-L-phenylalanine methyl ester, characterized in that the wet crystals of alpha -L-aspartyl-L-phenylalanine methyl ester are granulated so that the specific surface area during the drying operation is at least 4 m<2>/g, followed by drying.
