A University of Arizona professor is turning the process of selecting a price of fruit from "an art [to] a science." He has come up with a new way to help let people know when fruit is ripe and ready for eating, eliminating all that sniffing, poking and prodding of fruits in the market. His creation is a sticker called RediRipe that changes from white to blue as ethylene gas, a natural ripeness indicator, is released from the fruit or vegetable.
The first batch of the stickers will go straight to growers, who will be able to use them to monitor their crops and prevent spoilage of over-ripe fruits by shipping out the fruits ripening the fastest, first. It is worth mentioning that the stickers do not change to indicate overripe fruit themselves, so something that is "ripe" according to the sticker, may actually be too soft on the inside.
