摘要： A process for quickly and reproducibly obtaining .alpha.-L-aspartyl-L-phenylalanine methyl ester with controlled water content is disclosed. Wet crystals of .alpha.-L-aspartyl-L-phenylalanine methyl ester obtained by crystallization are subjected to a drying step to adjust the water content to not more than 5 wt %, and subsequently a gas adjusted to a temperature of 20-80.degree. C. and relative humidity of 20-90 RH % is contacted with the dried crystals to control water content.
