Product Name:Calcium Ascorbate
English Name:Calcium Ascorbate
CAS No.:5743-28-2
Aliases:Calcium L-ascorbate, L-Ascorbic acid calcium salt, Vitamin C calcium salt
Molecular Formula:C12H14CaO12
Physical Properties:White to off-white crystalline powder or granules, odorless or with a slight characteristic odor; relative molecular mass approx. 390.31; freely soluble in water, slightly soluble in ethanol, insoluble in ether and chloroform; pH of 5% aqueous solution approx. 6.0–7.5; decomposes on heating without a definite melting point; has antioxidant activity and should be kept sealed and protected from light.
Uses:Used as a dual nutritional supplement providing vitamin C and calcium, widely applied in foods, beverages, health products and functional foods; serves as an antioxidant (E302) to prevent oil oxidation and protect the color of fruit and vegetable products; also used in pharmaceuticals as an adjuvant treatment for vitamin C deficiency and calcium deficiency.
