ANSWER

Ascorbic Acid as Antioxidant

Autoxidation causes food and beverage spoilage and leads to discoloration, as well as the formation of off-flavours and odours.  The resulting vitamin loss results in shortened shelf life and loss in nutritional value. This condition can be improved by adding antioxidants for extending shelf life.

Ascorbic acid is a water soluble antioxidant which plays an important role as a food additive and it is used extensively in the food industry (U.S. Patent No. US 3718482 A, 1973; El-Samragy, 2012).
