Antioxidant properties of apple slices stored in starch-based films

Abstract

The aim of this study was to evaluate the antioxidant properties of apple slices stored in edible starch films enriched with white and green tea extracts. All results were compared to that obtained for apple slices stored in polyethylene films. The use of starch films, as carrier of antioxidants, prolonged the storage life and improved quality of fresh-cut apples at the end of storage; however, deteriorated their lightness and increased their browning. Apple slices coated in starch films enriched with tea extracts exhibited higher antioxidant properties than those without these additives, as well as those in polyethylene films.
