Mineral ascorbates are powders manufactured by reacting ascorbic acid with mineral carbonates in aqueous solutions, venting the carbon dioxide, drying the reaction product, and then milling the dried product to the desired particle size.
Ascorbate salts may be better tolerated by the human body than the corresponding weakly acidic ascorbic acid.
Examples of mineral ascorbates are:
- Monosodium ascorbate (E301)
- Calcium diascorbate (E302)
- Monopotassium ascorbate (E303)
- Magnesium diascorbate
