Hellmann’s launches ‘smart jar mayo jar’ that fights food waste by telling you if your fridge is too warm.

In an effort to reduce food waste, Hellmann's has introduced a new "smart jar" that alerts you if your refrigerator is too warm.

The label on the mayonnaise jar uses heat-sensitive ink that, when temperatures drop below five degrees, reveals secret messages and amusing graphics.

Once opened, store-bought mayonnaise is likely to spoil more quickly than other foods kept at higher temperatures.

The new prototype "smart jar" label was created by illustrator Ellen Porteus and unveiled to commemorate Food Waste Action Week 2023 (March 6–12).

Hellmann’s partner, climate action NGO WRAP, also has an online tool explaining how to set any brand of fridge to its correct temperature to help reduce instances of food going to waste

In addition to enhancing the enjoyment of food, Hellmann's aims to inspire people to be more resourceful with the food they have on hand and reduce food waste. The Hellmann's Fridge Night app, released last year, offers a 4-week in-app programme of weekly challenges and adaptable recipes to help Brits stretch their food and budget further.
