Best Practice Chloride Determination Methods for Food Quality Laboratories

Accurate chloride determination via titration helps monitor salt levels in processed foods and beverages. This application note package describes best practices for industrial food laboratory chloride measurement ranging from entry-level to advanced automated titration solutions.


Chloride is an essential nutrient in the human diet. Its electrolytic properties in blood and the digestive system help balance cell fluids throughout the body. While some foods contain high natural levels (tomatoes, olives, seaweed), chloride is primarily added to food as sodium chloride, either via table salt or, particularly within industry, during food processing. As excessive salt consumption causes health issues, authorities commonly regulate levels in foods.

Accurate chloride determination – due to its correlation with salt content – via titration helps to monitor quality and to control levels in processed foods. Titrator technology advancements continually make chloride determination more accurate and reproducible between operators, and faster for high sample loads while simplifying ease of use.
