Phenolic acids as antioxidants

Abstract

The phenolic compounds have been widely studied due to their influence on food quality. They are constituted by a large amount of substances, among them the phenolic acids, which have antioxidant properties, as a result of their chemical structure. So, the present review collects several papers that evaluated the antioxidant potential of the phenolic acids for the lipid foods preservation. This study also collects papers about the antioxidant action of these compounds in biological systems through the neutralization of free radicals produced in the organism, which are associated with many pathologies like cancer and heart disease.
