Titrimetric determination of ascorbic acid with 2,6-dichlorophenol indophenol in commercial liquid diets. 1983

D E Hughes

The titrimetric determination of ascorbic acid in the presence of a variety of potentially physically and chemically interfering species in commercial liquid diets is presented. The titrant and indicator was a solution of 2,6-dichlorophenol indophenol. Iron(II), copper(II), cysteine, glutathione, sulfite, and tin(II) do not interfere.

D001205	Ascorbic Acid	A six carbon compound related to glucose. It is found naturally in citrus fruits and many vegetables. Ascorbic acid is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways. Vitamin C is considered an antioxidant.
