UBC researchers are developing a non-plastic food wrap for the grocery industry, using blueberries. The claim is that this not only protects the food, but is making it more nutritious as well.
At present, plastics are the most commonly used food packaging materials globally. These materials are mostly non-reusable, non-biodegradable, and can, under specific conditions, lead to toxic outcomes and severe environmental consequences.
That is why considerable research activity has been directed to finding alternatives to plastic packaging materials, mainly due to increasing consumer awareness toward individual health, food and nutritional quality, food safety and environmental sustainability.
As such, innovations in developing edible packaging films have resulted in environmentally friendly, non-toxic and biodegradable products. These films are typically made from plant-based components, such as polysaccharides, proteins and lipids, or a combination of all.
