ABSTRACT:
A process of preparing N-substituted aldonamides, the process including the steps of mixing and reacting an aldonolactone and an amine in an organic polar solvent, in the presence of an antioxidant and a reducing agent. The aldonamides have improved color; the discoloration or browning of the aldonamides upon storage or elevated temperature processing is eliminated or substantially minimized.
