Hellmann’s has released a new ‘smart jar’ which tells you if your fridge is too warm – in a bid to reduce food waste. Using heat-sensitive ink, the label on the mayonnaise jar reveals hidden messages and quirky graphics - once temperatures drop below five degrees.
Any foods kept at higher temperatures are likely to go bad at a faster rate - and this includes shop-bought mayonnaise once opened. Unveiled to mark Food Waste Action Week 2023 (March 6th-12th), the new prototype ‘smart jar’ label was designed by illustrator Ellen Porteus.
This follows a prior study by food waste charity, WRAP which reported the average fridge temperature in the UK is seven degrees – way above the optimum three to five. Fresh foods like milk, fruit, and vegetables particularly benefit from being stored at five degrees or less - as they can last three or more longer days as a result.
