An overview of fruit and vegetable edible packaging materials

Various edible fruit and vegetable materials, including purees, residues, extracts, and juices, have been investigated in terms of their matrix‐forming properties to produce edible packaging materials to be applied to food products influencing their overall quality and improving the efficiency of synthetic packaging, thus leading to the reduction in amount of synthetic polymers used for each application. The potential of fruit and vegetables to be used as components of edible packaging materials is discussed. Such application of fruits and vegetables is possible thanks to the presence of matrix‐forming polysaccharides and proteins in their composition while the presence of bioactive compounds such as vitamins and polyphenols may confer, eg, antioxidant and antimicrobial properties of active packaging materials. The development of edible fruit and vegetable packaging materials is a promising way of combining the barrier and mechanical properties of biopolymers with the nutritional and sensory properties. The application of fruit and vegetables as a component of edible packaging materials enables the utilization of raw materials with low commercial value. Edible packaging materials are a new method of their utilizing. There is also the possibility of just decreasing the amount of synthetic packaging waste by application of fruit and vegetable packaging materials simply as a passive or active layer partially replacing the non‐renewable materials. This review discusses the potential of fruits and vegetables to be used as main components of edible packaging materials (films, sheets and coatings). Such application of fruits and vegetables is possible thanks to the presence of matrix‐forming polysaccharides and proteins in their composition while the presence of bioactive compounds such as vitamins and polyphenols may confer the properties of active materials, e.g. antioxidant or antimicrobial.
