Determination of Peroxide Value

What is the Peroxide Value Number? Why should it be appointed?

Determination of peroxide in oils is a measure of the amount of active oxygen in its content, and it is the amount of peroxide oxygen in 1 g of oil in micrograms.

The deterioration of the oils is mostly in the storage phase; oxygen, metal ions, temperature, light, etc. takes place with its effects.

The determination of whether the deodorization process is performed effectively in oils is determined by the amount of peroxide. In addition, peroxide determination is a parameter that enables us to have information about the degree of oxidation. Peroxide value determination or kreiss test is applied to determine the rancidity (deterioration) of the oils.

Determination of peroxide is based on the principle that potassium iodide is oxidized with the peroxide oxygen in the oil and the iodine is released and this free iodine is titrated with thiosulfate.
