Antioxidant activity of phytosteryl phenolates in different model systems

► Antioxidant activity (AA) of phytosteryl phenolates (PP) was evaluated. ► The AA of PP depended on the model system employed. ► PP showed similar or lower AA compared with phenolic acid counterparts in bulk oil. ► PP showed enhanced AA except phytosteryl ferulates in an emulsion model system. ► LDL-cholesterol oxidation was moderately inhibited by PP.
