Ascorbic Acid

Ascorbic acid is the chemical name for vitamin C, a compound naturally found in fruits and vegetables, but also available in the kitchen as a white crystalline powder. In the food industry it is registered as additive E300 and primarily serves as an antioxidant that prevents oxidation and unwanted browning of cut fruit or vegetables. It is added to preserves, jams, fruit juices and meat products to aid preservation and maintain color. In larger quantities it imparts a distinctly sour taste to dishes. At home it is used, for example, when preparing homemade lemonades or as a supplement during fermentation.
