Sodium Ascorbate is a white to yellowish white crystalline powder or granules, E301, odorless, taste slightly salty. E301 decomposition temperature of 218 ℃, dry state more stable E301, E301 to deepen the color when exposed to light, moisture absorption and after the slow oxidation and decomposition in aqueous solution. E301 ascorbic acid soluble in water than (62g/100mL), 10% aqueous solution pH of about 7.5. Ascorbic acid and sodium bicarbonate reaction will be refined.

Sodium Ascorbate identification methods:
Sodium Ascorbate showed ascorbic acid and sodium reaction. See response to L-ascorbic acid ascorbic acid identification method. See acidity regulator sodium sodium carbonate reaction identification method.
Sodium Ascorbate 1g 0.9gL-equivalent to the physiological role of ascorbic acid, E301 ascorbic acid soluble than in water, and no sour, E301 easy to use, a reduction, E301-134-03-2 has anti-oxidants and protect coloring.
