Households across Wales are being encouraged to transfer blueberries from plastic containers to glass mason jars to extend their freshness, as plastic packaging often traps moisture and accelerates mould growth.
Val Riley, founder of Lovely Lucky Life, recommends the switch, stating that berries stay fresh for longer in glass jars because they allow better air circulation and prevent moisture buildup. Keeping the lid slightly loose helps humidity escape.
To prepare blueberries for storage, rinse them in a colander, pat dry with kitchen paper, and remove any damaged or mouldy fruits. Place them in a clean glass jar with a sheet of kitchen paper on top to absorb excess moisture, then store in the fridge with the lid loosely secured.
This method can extend the shelf life of blueberries by up to two weeks, reducing food waste and saving money. Riley notes that the fruits are often consumed before they spoil due to their improved longevity.
