What is Ascorbate?
Sodium ascorbate is one of a number of mineral salts of ascorbic acid (vitamin C), which is used by food industries to protect their product from deterioration, oxidation as Ascorbate is proved to have anti-oxidant property.It is the supplement of vitamin C and is more bioavailable and alkaline than ascorbic acid.
It is found naturally in citrus fruits and many vegetables.Ascorbate is white or almost white coloured odourless crystalline powder which darkens on exposure to light. As the solutions of ascorbic acid are rapidly oxidized in air and in alkaline media, the drug should be protected from air and light.
Synonyms or Chemical Names:Sodium ascorbate; L-Ascorbic acid sodium salt; Sodium L-ascorbate; 134-03-2; Vitamin C sodium; Ascorbicin
Molecular formula:C6H7O6Na or C6H7NaO6
Molecular weight:198.106 g/mol
Solubility: Ascorbate is soluble in water, very slightly soluble in alcohol and insoluble in chloroform.
Commercial Production of Ascorbate:
Sodium ascorbate is produced by dissolving ascorbic acid in water and adding an equivalent amount of sodium bicarbonate in water. After cessation of effervescence, the sodium ascorbate is precipitated by the addition of isopropanol.
History & origin of Ascorbate:
From the middle of the 18th century, lemon and lime juice help prevent sailors from getting scurvy. In 1928, Szent-Györgyi isolated an organic reducing agent, ascorbic acid (vitamin C), present in oranges, lemons and cabbage and are consumed to prevent and treat scurvy. Afterwards, Ascorbic acid was used in the preparation of various Vitamin C supplements like Ascorbate etc. used by human beings.
It can be found in pork pies, quick-frozen fish and lobster, sausages, scotch eggs, smoked frankfurters, tinned meats and both tinned and cereal based baby foods.
