Abstract

Antioxidant active packaging is one of the active packaging that prevents of lipid oxidation by releasing antioxidant during storage of food. In recent years the use of natural antioxidant instead of the synthetic variety in these packaging has been considered. The aim of this study was evaluating the performance of polymeric film coated with natural antioxidant (Rosemary Extract) to prevent lipid oxidation in butter. With three different concentrations (0.1%, 0.15%, 0.2%), the ethanolic extract of Rosemary was sprayed on the surface of low density polyethylene films (LDPE). Films without extract was used as control. Phenolic compounds migration from the surface of film to 95% ethanol (fatty food stimulant) was measured at 4ºc during 10 hours. With increasing time and extract concentration, migration to ethanol increased (P
