Longer shelf life for fresh produce

Swiss researchers have found a way of using fruit and vegetable peelings to make a coating that extends the shelf life of fresh produce. Staff at the Empa research body have been working with Lidl Switzerland since 2019 to develop what promises to be a game changer.

Bananas have been chosen to test Empa’s cellulose coating.

Testing the coating on bananas, a gain of up to a week was recorded in the product life. There is the added benefit that with a reduction in the use plastic materials, the risk of condensation or rot in transit is also lower. “The big goal is that such bio-coatings will be able to replace a lot of petroleum-based packaging in the future,” explains Gustav Nyström, head of the Empa lab.

Lidl Switzerland has 150 stores that will take part in testing the new coating as it continues its development over the next two years.
