Sticker would tell the ripeness of fruits and vegetables

TUCSON, Ariz. wasting money on bad fruit could become a thing of the past.

A University of Arizona professor has invented a sticker that could tell consumers if a fruit or vegetable is ripe. That means no more waiting for avocados to season or throwing out fuzzy peaches.

The stickers would be available to growers next year and must make their way into supermarkets within two to three years, said Mark Riley, who is a UA assistant professor of agricultural and bio-systems engineering.
