features wide use, early development, E302 easy synthesis, less pollution, high efficiency and lower costs. Of our food additives and food ingredients. 5743-28-2-E302 is a compound with the molecular formula CaC12H14O12. E302 is the E302 salt of ascorbic acid, one of the mineral ascorbates.

Calcium Ascorbate E302 system of law
E302 ascorbic acid and the alkaline and calcium in the system.
E302 identification method
Take a small amount of E302 soluble in water, add 2 drops of methyl red indicator, with ammonia and then add dilute hydrochloric acid to acid, adding ammonium oxalate solution to generate calcium oxalate precipitation. This precipitate insoluble and soluble in hydrochloric acid is the E302.
5743-28-2 can add soup and soup-style food and supplies, E302 without changing the original taste of food and physical activity to lose calcium VC. So 5743-28-2-E302 is a dual-function agent, to prevent rickets, scurvy.
