Tomato derivatives

The chloride test allows to identify the possible addition of sodium chloride in the tomato. The addition of salt is legislated on the basis of the type of product to be produced and therefore must respect the established limits. This analysis allows to quantify the concentration of salt in products such as peeled tomatoes, tomato puree and other derivatives.

Analysis of Chloride in tomato derivatives

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. 

Test type: End Point. Testing time: [uni]. Analysis sessions with multiple samples are possible up to a maximum of 16 tests for CDR FoodLab® and 3 tests for CDR FoodLab® Junior.<h3>Sample treatment</h3>Filter the sample before analysing.

Method

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.

Test Principle

Reaction involved in the analysis of chlorides in tomato products

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