The method consists in precipitating chloride by addition of an excess of a standard volumetric silver nitrate solution and titrating this excess with a standard volumetric potassium thiocyanate solution. If the product contains natural anthocyanin pigments, the method is applicable with specified modifications.
Abstract
Overview
ISO 3634:1979 is an international standard developed by the International Organization for Standardization (ISO) that specifies a precise chemical method for determining the chloride content in vegetable products. This analytical procedure plays a crucial role in food quality control, regulatory compliance, and agricultural product analysis. Utilizing volumetric titration techniques, the standard ensures consistent and accurate measurement of chloride concentration expressed as a percentage of sodium chloride by mass. It also includes modifications to accommodate vegetable products containing natural anthocyanin pigments, which might interfere with standard titration approaches.
