The Value of the Chemical Titration Method in Determining the Vitamin C Potency of Certain Food Substances

Abstract
A study has been made concerning the value of the chemical titration method for determining the vitamin C potency of certain food substances. In these studies, the ascorbic acid content of certainfruit and vegetable juices was determined by titrating against a standard solution of 2, 6-dichlorophenol-indophenol. In order to ascertain the accuracy of the data obtained through the chemical titration method, biological assays were also made on a number of the fruit juices used in this study. From the results obtained it appears that:
