Abstract

This paper provides a study on different testing methods for antioxidant activity. Four commonly used methods (LDL oxidation, TAS measurement, beta-carotene bleaching as well as a rapid screening test published by PRYOR et al. 1993) are compared on the basis of a set of model compounds. The differing results concerning the ranking order of the tested substances are discussed. Furthermore three methods which showed appropriate results were used in order to determine the antioxidant activity of Riesling wine fractions.
