Chapter 5. A modified method for estimation of true vitamin C with the aid of ascorbic acid oxidase.The estimation of true vitamin C with the aid of ascorbic acid oxidase as suggested by Tauber and Kleiner was modified, so as to differenciate true vitamin C from reductones within an error of less than ± 5%.The method depends on the fact that at pH 5.6-5.9 (temp. 10℃) in the presence of 4% oxygen (displacing the air by CO_2), ascorbic acid is quickly removed by the enzyme action, whereas reductones are but slowly removed.
