Shoppers may no longer need to squeeze their pears to test if they are ready to eat. A new label developed by researchers in New Zealand, is designed to change colour and show you when your fruit is at it’s best, without any squeezing needed. It does this by reacting to different levels of gases that fruit emit while they ripen, changing colour accordingly. So far a label is being tested for pears, which are notoriously difficult to tell when they are ripe, and if that takes off then the researchers are planning versions for kiwi fruit, avocados and melons.
