Title:
PRODUCTION OF ALPHA-L-ASPARTYL-L-PHENYLALANINE METHYL ESTER
Document Type and Number:
Japanese Patent JP3409396
Kind Code:
B2
Abstract:
PURPOSE: To provide a method for stably producing a dry substance of α-L- aspartyl-L-phenylalanine methyl ester with a controlled moisture content.
CONSTITUTION: This method for producing α-L-aspartyl-L-phenylalanine methyl ester is to dry a wet crystal of the α-L-aspartyl-L-phenylalanine methyl ester obtained by crystallization and separation, regulate the moisture content thereof to ≤5[%] on the basis of wet weight, then flow a gas regulated to a temperature within the range of 20-80[°C] and a relative humidity within the range of 20-90[RH%], bring the regulated gas into contact with the dried crystal and control the moisture content thereof.
