Abstract

Addition of small amounts of EDTA to acidified sofutions of ascorbic acid. completely protects the vitamin against copper-catalysed aerobic oxidation for over 6 days at room temperature. In the absence of acid. excess EDTA acts as a pro-oxidant for the vitamin. Under optimal conditions solutions of ascorbic acid containing EDTA could be heated on the water-bath to complete evaporation without allY loss of the vitamin.
