New Antioxidant Ldpe Films Containing Apple And Ginger Extract

In recent years, a new type of packaging that merges usual food packaging materials with antioxidant substances to extend shelf-life is gaining interest in the packaging industry. Various natural antioxidant compounds can be combined with different types of packaging materials to replace the chemical additives in food industries. In this work, the most suitable fruit extract between apple/ginger and apple/ginger/carrot/beet in term of antioxidant activity has been determined. LDPE-based films have been loaded with apple/ginger (50/50) extract by a melt mixing and compression process. Structural and functional properties of the obtained active films have been investigated together with their antioxidant activity.
