CDR FoodLab® is the chemical analyzer for quality and process control that allows you to determine a wide range of parameters of many foods, animal feeds and pet foods.

Chloride test in milk, cheese and water solution

The chloride test allows to identify any added salt water in the milk, a sophistication that the normal cryoscopic examination does not detect. This analysis allows to quantify the concentration of salt in products such as cheese, and liquid of processing and storage of dairy products.


Test principle

Reaction involved in the analysis of chlorides in milk and dairy products

Chloride ions react with mercuric thiocyanate and form thiocyanate ions. The thiocyanate ions react with the Fe (III), giving an orange-colored complex whose intensity, measured at 505 nm, is directly proportional to the concentration of chlorides in the sample.

Calibration curve

Comparative tests, on samples of whole milk performed between the reference method and the CDR FoodLab® method, made in a leading milk production company, have confirmed a very good alignment between the two systems.
