Mineral ascorbates

Mineral ascorbates: Ascorbic acid

Mineral ascorbates are salts of ascorbic acid (vitamin C). They 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.

The choice of the mineral carbonates can be calcium carbonate, potassium carbonate, sodium bicarbonate, magnesium carbonate, or many other mineral forms. Ascorbates are highly reactive antioxidants used as food preservatives.

Ascorbate salts may be better tolerated than the corresponding weakly acidic ascorbic acid.

Examples of mineral ascorbates are:

Monosodium ascorbate (E301)

Calcium diascorbate (E302)

Monopotassium ascorbate (E303)

Magnesium diascorbate
