Chitosan/grapeseed oil multicomponent edible films - design and properties

Abstract

Abstract Physical and antioxidant properties of edible chitosan films, formed by casting method, were investigated. The films were loaded with grapeseed oil (GsO), which is a strong antioxidant, contains vitamin E and protects human cells against cancer. The mechanical puncture characteristics, thickness, water uptake, barrier, and antioxidant (DPPH assay) properties of the films were investigated. The results showed that the addition of GsO to chitosan film accelerated the oxygen and water vapor exchange and reduced the strength of the films. The increased antioxidant activity of the films is a prerequisite for extending the shelf life of food products packaged in them.
