Biobased Materials as a Sustainable Potential for Edible Packaging

Edible packaging obtained from natural biopolymers as an alternative to synthetic food packaging have become very attractive for food engineers, scientists and consumers due to their edibility, functionality, biodegradability and compostability. Development of edible films and coatings with improved physical, mechanical, functional, barrier and sensory properties is a key for applications in different food sectors as wrapping and packaging materials. Biobased and biodegradable materials are ideal candidates as components to edible packaging. In addition, bioactive compounds and nutraceuticals, especially compounds extracted from by-products, are ideal addition to edible materials in context of extending their role towards active and intelligent packaging options. In this context, nanotechnology tools enable proper inclusions of the bioactives and nutraceuticals into edible materials; increase the stability of bioactive compounds, utilisation and delivery mechanisms from the packaging to food item or human body, but also to extend their usage, improve the quality and safety of packed food items.
