How is Potassium Ascorbate prepared?
Both Ascorbic Acid and Potassium Bicarbonate in highly refined crystalline form (see answer to question 1) are extremely unstable, highly hygroscopic (moisture-sensitive). In addition, Potassium Ascorbate is very photo-sensitive (i.e. it is easily damaged by exposure to visible sunlight and ultra-violet rays). Both products must, therefore, be packaged in vacuum-sealed, pre-weighed sachets in a moisture-free environment.
