ascorbic acid


Ascorbic acid powder is a white or light yellow solid in appearance. It dissolves well in water to give mildly acidic solutions


Ascorbic acid has a sour acidity taste



Acting as an antioxidant, ascorbic acid can improve the colour and palatability of many kinds of food products. By removing oxygen from its surroundings, ascorbic acid in its reduced form becomes the oxidized form, dehydroascorbic acid. This oxidizing action reduces the available oxygen in its immediate environment, making ascorbic acid an effective antioxidant.

Ascorbic acid is used in food and beverages to increase the vitamin C levels which are then consumed by people who don’t get enough in their diets. Vitamin C is vital to a healthy diet as it is needed to maintain healthy skin, cartilage, bones and blood vessels.

  • Addition of Ascorbic Acid is common in the manufacture of beverages, especially fruit juices. Ascorbic acid not only restores nutritional value lost during processing, but also contributes to the products’ appearance and palatability.
  • In the manufacture of fruit juices or purees from fruits such as apples and peaches, ascorbic acid may be added during the crushing, straining, or pressing processes to prevent enzymatic browning of the raw fruits. Ascorbic acid can inhibit browning reactions by reducing the quinones back to the original phenol compounds.
  • Ascorbic acid is also widely used in the meat industry for its antioxidant properties. In cured meats, ascorbic acid can accelerate colour development, inhibit nitrosamine formation (Nitrosamine is carsinogenic), prevent oxidation and prevent colour fading. Ascorbic acid is also used in fresh meat to prevent oxidation and colour fading during storage.
  • In Dough systems adding ascorbic acid to flour improves bread texture and loaf volume. Ascorbic acid is first oxidized to dehydroascorbic acid. Then the reduction of dehydroascorbic acid back to ascorbic acid drives the reaction of sulfhydryl compounds in the gluten to form intermolecular disulfide bonds.
  • In addition to its benefits as a processing aid and preservative, ascorbic acid has nutritional value in food products. Fruits, vegetables and juices are primary sources of vitamin C in the diet, but during processing and storage, vitamin C losses may occur.
