Ascorbic acid food chemistry

Ascorbic acid and its sodium, potassium, and calcium salts are frequently acclimated as antioxidant aliment additives. These compounds are water-soluble and, thus, cannot assure fats from oxidation: For this purpose, the fat-soluble esters of ascorbic acid with long-chain blubbery acids (ascorbyl palmitate or ascorbyl stearate) can be acclimated as aliment antioxidants. Eighty percent of the world's accumulation of ascorbic acid is produced in China.
The accordant European aliment accretion E numbers are:
E300 ascorbic acid (approved for use as a aliment accretion in the EU USA and Australia and New Zealand)
E301 sodium ascorbate (approved for use as a aliment accretion in the EU USA and Australia and New Zealand)
E302 calcium ascorbate (approved for use as a aliment accretion in the EU USA and Australia and New Zealand)
E303 potassium ascorbate
E304 blubbery acid esters of ascorbic acid (i) ascorbyl palmitate (ii) ascorbyl stearate.
It creates airy compounds if alloyed with glucose and amino acids in 90 °C.
It is a cofactor in tyrosine oxidation.
