Determination of Sodium Chloride in Foods and Other Samples by Quantab ™ Chloride Titrators

Laboratory Procedure MFLP-45
April 1997

1. Application

This method can be used to determine chloride content of most foods. The kit will provide results as % sodium chloride or ppm Cl ^- on a wet weight bases. In order to determine % brine it will be necessary to determine the moisture content of the sample. If a regulation specifies an Official Method then that method should be followed such as MFO 38 for % salt in smoked fish products.

2. Principle

Quantab™ Chloride Titrators are convenient test devices used to measure the chloride content in aqueous solutions or dilute aqueous extracts of solids. These devices contain all the reagents necessary to carry out standard chloride titration. The titrators are pre-calibrated and provide quantitative results which are easy to read and interpret.
