Development of a Potential Reference Material for Evaluating Antioxidant Activity A paper in the May/June issue of the Journal of AOAC INTERNATIONAL describes a multicomponent phenolic mixture being used as a potential reference material for assaying antioxidant activity in food. The new reference material, which was chosen for solubility, stability at low temperatures, occurrence in common foods, and bioactivity, will be used for a single-laboratory validation (SLV) study of total phenolics and antioxidant capacity of food using different methods. Antioxidants, which counteract the damaging effects of oxygen in tissues, are often in the news because research suggests an inverse correlation between intake of antioxidant-rich fruits and vegetables and the occurrence of inflammation, cardiovascular disease, and certain forms of cancer. But there are conflicting results on the antioxidant activity for individual polyphenolic compounds such as teas, herbs, and spices. These variations may be due to the single compound reference material being used, or the type of assay. The paper, written by U.S. Department of Agriculture researchers Devanand Luthria and Bryan Vinyard, is included in the May/June issue of the Journal of AOAC INTERNATIONAL.
