PROCESS FOR THE PURIFICATION AND RECOVERY OF SWEETENER |
| 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. |
