    Abstract: A process for efficiently and industrially advantageously producing an N-formylamino acid by reacting an amino acid or its salt with formamide and/or methyl formate in the presence of a base. A process for efficiently and industrially advantageously producing N-formyl- alpha -aspartylphenylalanine methyl ester, which is a precursor of aspartame, by an enzymatic fusion reaction of N-formylaspartic acid with phenylalanine methyl ester wherein the concentration of N-formylaspartic acid is specified or the reaction is carried out in the presence of a trialkyl phosphate. A process for efficiently and industrially advantageously producing N-formyl- alpha -aspartylphenylalanine methyl ester having a high purity by adjusting the pH value of a phenylalanine methyl ester adduct of N-formyl- alpha -aspartylphenylalanine methyl ester.

    Abstract: A process for efficiently producing a monatin useful as a sweetener, especially an optically active monatin, comprising carrying out a reaction of isomerization at 2-position of a monatin whose 2-position and 4-position configurations are different from each other in the presence of an aldehyde in a mixed solvent of water and organic solvent at a pH of 4 to 11 and simultaneously performing crystallization of a monatin whose 2-position and 4-position configurations are identical with each other or a salt thereof.

    Abstract: A method of purifying and recovering a sweetener efficiently in a high yield without conducting complicated steps, which comprises contacting crude methyl N-(3,3-dimethylbutyl)-α-L-aspartyl-L-phenylalaninate containing at least methyl α-L-aspartyl-L-phenylalaninate as an impurity with a mixed solvent having two layers respectively consisting of water and an organic solvent immiscible with water to extract the methyl N-(3,3-dimethylbutyl)-α-L-aspartyl-L-phenylalaninate with the organic solvent layer.
