Cheese gets its unique taste from mould. But not all types of mould are welcome.

An international research team from Singapore and the USA has developed an antibacterial film that keeps food fresh for longer.

The hydrophobic, non-toxic packaging material is made from starch, corn protein and biopolymers. Thyme oil and citric acid serve as secret ingredients.

These last two substances are only released when in contact with bacteria or fungus, or when air humidity is high. Then they prevent foods from spoiling.

During tests, strawberries stayed fresh for 3 days longer than with traditional plastic packaging.

Using the new film would be a big win for sustainability, since its components are all biodegradable.

And it’s far from alone there.
