Omega 3 fatty acids (n-3 FA) and plant sterols esters (PSE) are bioactive compounds able to promote cardiovascular protection. However, both are susceptible to oxidation, producing toxic derivates that annul their beneficial functional effects. Thus, the aim of this study was to compare the action of eleven natural phenolic compounds extracted from red propolis in the oxidative stability of an emulsion added of n-3 FA and PSE. Among the 11 phenolic compounds evaluated in this study, sinapic acid and rutin hydrate were the most efficient ones to delay lipid oxidation. Therefore, these two compounds represent a potential alternative as natural antioxidant to be applied in a functional emulsion containing of n-3 FA and PSE.

Abstract
Omega 3 fatty acids (n-3 FA) and plant sterols esters (PSE) are bioactive compounds able to promote cardiovascular protection. However, both are susceptible to oxidation, producing toxic derivates that annul their beneficial functional effects. Thus, the aim of this study was to compare the action of eleven natural phenolic compounds extracted from red propolis in the oxidative stability of an emulsion added of n-3 FA and PSE. Among the 11 phenolic compounds evaluated in this study, sinapic acid and rutin hydrate were the most efficient ones to delay lipid oxidation. Therefore, these two compounds represent a potential alternative as natural antioxidant to be applied in a functional emulsion containing of n-3 FA and PSE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
