Total oxidation value (TOTOX) of food or feed

The TOTOX value is a useful indicator of the overall oxidation of fats and oils. It is calculated using indicative values for primary oxidation products (peroxide value) and secondary oxidation products (p-Anisidine value).

This TOTOX analysis covers peroxide value and p-Anisidine value determinations, the results of which are reported in addition to the total oxidation value. The method also includes an extraction step, after which the analyses are performed on the extracted fat or oil.

All food and feed products that contain fat can be analyzed.
