title: [Determining the level of dehydroascorbic acid in food products].
abstract: Ascorbic acid stability was studied under conditions of dehydroascorbic acid assay. The minimum amounts of cysteine and volumes of reagents utilized were specified. Based on the data of 2,6-dibromoindophenol stability the method of indophenol-xylol extraction was proved to be unsatisfactory for the assay of dehydroascorbic acid.
