  • Ascorbic acid is a sugar acid with antioxidant properties. Its appearance is white to light-yellow crystals or powder and it is water-soluble. The L-enantiomer of ascorbic acid is commonly known as vitamin C.
  • Ascorbic acid is known for its antioxidant properties. It is a molecular bond of carbon, hydrogen, and oxygen.
  • Ascorbic acid is the water soluble form of vitamin C. It is considered a potent antioxidant and studies suggest that this nutrient may assist in the prevention of early death from heart disease and cancer. Ascorbic acid was originally revered for its anti-scurvy properties, but the focus on this supplement today is more on its potential ability to protect cells.
  • Ascorbic acid strengthens the capillaries and cell walls and is an essential component of collagen formation. It functions in protein synthesis by changing the charge of iron so that it can be absorbed and works as an antioxidant.
  • Ascorbic acid is known to be a vitamin sensible to a number of factors, including pH, moisture content, oxygen, temperature and light.
  • The biosensor based on carbon paste modified with crude extract of zucchini (Cucurbita pepo) for determining L-ascorbic acid in pharmaceutical formulations is stable, selective, sensitive, simple and low cost.
  • L-Ascorbic acid is conventionally synthesized by a variety of known methods, which are generally variations of the Reichstein process. These are mostly relatively complex chemical processes that utilize glucose as a starting material.
  • The synthesis of L-ascorbic acid from D-glucose (Glc) proceeds via glucuronic acid and L-gulono-1,4-lactone (Gul) in animals, in plants the Glc is epimerized to Dmannose and then to L-galactose, and finally L-galactono-1,4- lactone (Gal) is converted into the vitamin.
  • Ascorbic acid is easily oxidized and so is used as a reductant in photographic developer solutions and as a preservative.
  • Ascorbic acid and its sodium, potassium, and calcium salts are commonly used as antioxidant food additives. These compounds are water-soluble and thus cannot protect fats from oxidation.
  • L-Ascorbic acid (Vitamin C), an anti-oxidant and free radical scavenger, is found ubiquitously in fruit and vegetables such as citrus fruits (oranges, lemons, limes, tangerines etc), melons, tomatoes, peppers, broccoli, green leafy vegetables such as spinach, potatoes and turnips. Its quantitative determination is especially important in the production of wine, beer, milk, soft drinks and fruit juices, where it can be a quality indicator.
  • The ascorbic acid essential role played in the human diet, L-ascorbic acid (E300) and salt derivatives (E301-303) are commonly used as food additives, with the additional advantage of their antioxidant and flavour enhancing properties. In the wine industry, L-ascorbic acid can be added to prevent oxidation of wine.
  • Demand for Vitamin C in the world went on increasing, first at a slow rate, and then at a high rate - upto 10% per year. The present world demand for Vitamin C is about 70,000 Tonnes per year. In India, present demand for Vitamin C is of the order of 1,100 Tonnes per year.
  • The Indian manufacturers are operating at an overall efficiency of conversion of sorbitol to Vitamin C in the range of 44% to 48% which is only slightly lower than the world standard of 51%. However, their utility consumptions are on the higher side and the fixed cost is high dueto lower production capacity.
  • The demand for Vitamin C in the world is increasing at about 27 per year. This rale may not increase, unless new therapeutic or other
    applications of Vitamic C are invented. The manufacturing plants in the world, have excess capacity over the present demand.
  • The actual production of Vitamin C in the past years was about 650 tonnes. The formulators of Vitamin C, were not getting the required quantity of Vitamin C, as the production was low. Moreover, manufacturers of Vitamin C were diverting their production to food grade Vitamin C.
  • The global market for isoascorbic acid, ascorbic acid and citric acid is expected to reach $1.7 billion in 2007.
  • Prices of citric acid and of ascorbic acid are very close, or even below estimated production costs. This is a result of a downward spiral started with the market entry of Chinese producers offering these products at well below market prices. Chinese producers currently have a market share of 37 per cent in isoascorbic acid, 65 per cent in ascorbic acid and 34 per cent in citric acid.
