Abstract
Overview
ISO 6557-2:1984 describes routine laboratory procedures for the determination of ascorbic acid (expressed as dehydroascorbic acid equivalent) in fruits, vegetables and derived products. The standard specifies two complementary approaches: a titrimetric method (Method A) using 2,6-dichlorophenolindophenol dye and a spectrometric method (Method B) after extraction with xylene. Both methods are intended for routine quality control and monitoring of agricultural and food products.
