INTRODUCTION:
L-Ascorbic acid (Vitamin C), an anti-oxidant and free radicalscavenger, is found ubiquitously in fruit and vegetables such as citrusfruits (oranges, lemons, limes, tangerines etc.), melons, tomatoes,peppers, broccoli, green leafy vegetables such as spinach, potatoes andturnips. Its quantitative determination is especially important in theproduction of wine, beer, milk, soft drinks and fruit juices, where itcan be a quality indicator. Given the essential role played in the humandiet, L-ascorbic acid (E300) and salt derivatives (E301-303) arecommonly used as food additives, with the additional advantage of theirantioxidant and flavour enhancing properties. In the wine industry,L-ascorbic acid can be added to prevent oxidation of wine.
