You can tell the ripeness of mango without tasting

You may soon be able to tell how ripe a mango is without having to taste it as researchers have identified a way to “sniff” the ripeness of the fruit.

They have identified the unique chemical signature of ripening for mangoes, a development that could lead to small hand-held electronic noses to detect the ripeness of not just mangoes but other fruits as well.

Mangoes are one of the most important and popular tropical fruits with India producing approximately 40 per cent of the world’s supply.

 

“It is really important for people to be able to tell how ripe fruit is without having to taste it. This is important for fruit producers and supermarkets,” said lead researcher Paul Monks, professor at the University of Leicester in Britain.

The new research, published in the journal Metabolomics, has shown that is possible to ‘sniff’ the ripeness of mangoes.

“We used a novel fast-sensitive “electronic-nose” for sniffing volatile compounds from the ripening fruit. In particular, the work showed an increase in ester compounds —the smell of pear drops —was a particular marker of over ripe fruit,” Monks noted.
