The analysis of metrological characteristics of the amperometric antioxidant measuring method is carried out. It is confirmed, that the amperometric method makes it possible to determine correctly an antioxidant activity (the total rate of oxidation reactions). On the other hand, the use of this method for the indirect measuring the antioxidant capacity (the total antioxidants concentration) may result in sufficient measurement errors.
