Abstract
PURPOSE: To measure the peroxide value simply and at a high accuracy by measuring the color formed on a reagent when it is oxidized in the presence of a certain kind of metal compound.
CONSTITUTION: The color formed on the reagent when it is oxidized is measured, which reagent is changed to the colored compound when it is oxidized in the presence of the metal compound having at least two kinds of valences, by the peroxide contained in a sample, which is other than a live sample, for example, fat, fat-processed food and ether compound. A sufficient amount of sample in use is 5W50μl in ordinary cases. In a case where a sample contains a considerably large amount of a metal compound having at least two kinds of valences, a metal compound may not be added thereto.
