Abstract
Alkylresorcinols (ARs) are a homologous series of natural phenolipids extracted from rye bran which have shown antioxidant activity in bulk oils and oil-in-water emulsions. This application is directed to their use in low-moisture foods using crackers as a model system. ARs (153 μmol) inhibited lipid oxidation reactions based on delayed formation of primary and secondary products of lipid oxidation compared to a control treatment, and were more effective than α-tocopherol. The antioxidant activity of ARs of compound of Formula (I) increased as alkyl chain length increased, with optimum activity at alkyl chain length C23:0. There was no effect of alkyl chain length on rate of AR loss. ARs are effective antioxidants in low-moisture foods likely due to their hydrophobic nature, which allowed them to localize in the lipid phase, the purported site of lipid oxidation in the model cracker system.
