Изобретение касается способа кристаллизации альфа-L-аспартил-L-фенилаланин- метилового эфира (АФМ) из его раствора посредством охлаждения. В этом способе кристаллы АФМ осаждают посредством прямого контакта со льдом. Кристаллы, осаждающиеся согласно настоящему способу, - крупные, прочные и обладают прекрасными свойствами для фильтрования.The invention relates to a method for the crystallization of alpha-L-aspartyl-L-phenylalanine methyl ester (AFM) from its solution by cooling. In this method, APM crystals are precipitated by direct contact with ice. The crystals precipitated according to the present method are large, durable and have excellent filtering properties.
