Process for the preparation of N-acylated amino acid mixtures, N-acylated amino acid mixtures, and their uses

摘要

The invention relates to a process for the preparation of a mixture of at least two N-acylated amino acids whose carboxylic functions are free or salified according to which the following steps are carried out: (a) selection of determined at least two amino acids of different nature in individualized form, BR/ b) a mixture is made from the amino acids selected in step a), BR/ c) N-acyl amino acids of the mixture formed in step b), BR/ and, where appropriate, BR/ d) the free carboxylic functions of the N-acyl amino acids are salified. The invention also relates to mixtures of N-acylated alpha amino acids whose carboxylic functions are free or salified, said alpha amino acids being constituted by alpha amino acids whose nature is identical to that of alpha amino acids. constituents of a selected protein and whose content in said protein is greater than or equal to 2% by weight, said mixture being substantially free of condensate of N-acylated alpha amino acids. / P
