The innovative film is made of chitosan, a natural molecule found in shellfish shells. This food industry by-product contains key antifungal properties that curb mould growth. The packaging film also contains essential oils and nanoparticles, both of which possess antimicrobial properties.

"Essential oil vapours protect strawberries. And if the film comes into contact with strawberries, the chitosan and nanoparticles prevent mould and pathogens from reaching the fruit's surface," said Professor Lacroix, expert in sciences applied to food.
