Abstract

Surface-treated crystals of a solid edible organic acid, especially citric acid, have some of the acid molecules on the surface in ammonium, alkali metal or alkaline earth metal salt form such that the proportion of ammonium, alkali metal or alkaline earth metal ions on the surface is 0.01-5 (especially 0.1-1.5) wt. %. An Independent claim is also included for production of the surface-treated crystals by treating crystals of the acid with a solution containing alkali(ne earth) metal ions or with ammonia vapor, stopping the reaction after a predetermined time, and drying the crystals.
