Is This Fruit or Veggie Ripe? Just Check the Sticker |
An Arizona inventor has come up with a sticker, if put on a fruit or vegetable, will tell you whether it is ripe. Riley's RediRipe stickers detect a chemical called ethylene gas and turn from white to blue when the produce ripens.
“And there are still bugs to be worked out: The stickers do not change color to reflect an over-ripe or rotten piece of fruit. Also, not all fruit produces enough ethylene to be detected by the the sticker, said Jim McFerson, manager of the Washington Tree Fruit Research Commission, a growers' research group that helped sponsor the research.”Blue sticker says when it's ripe; good news for shoppers, grocers – Arizona Daily Star
