Ripeness Sticker Coming to Supermarket Fruit

Posted by ryuzaki0 on from the give-me-talking-fruit-science dept.

Adam Weiss writes "A biosystems engineering professor has just announced a "ripeness sticker" for fruit. According to this AP article, grocers throw out thousands of bushels of fruit a year because it ripens too fast (1 bushel is about 9 U.S. gallons). Mark Riley's RediRipe stickers turn from white to blue as fruit ripens. The stickers react with ethylene gas, a chemical which is released as fruit or vegetables ripen. However the article says "there are still bugs to be worked out: The stickers do not change color to reflect an overripe or rotten piece of fruit. Also, not all fruit produces enough ethylene to be detected by the sticker.""

    The stickers do not change color to reflect an overripe or rotten piece of fruit.
    Luckily, the fruit itself still does. Do you really need science to tell you not to eat the dark brown apples or fuzzy green oranges?
