RediRipe is a technology created at the University of Arizona which detects the production of ethylene, a natural ripening hormone, and displaying that detection by means of a color-changing sticker that changes from white to blue.[1][2][3]

The technology was created in the lab of Mark Riley at the University of Arizona.[4][5] In conjunction with the Eller College of Management's McGuire Center for Entrepreneurship, the technology was being developed into a viable business that will assist the apple and pear industries in their efforts to improve their efficiency by integrating technology into their age-old processes. Additionally, this technology has potential on other climacteric fruits which emit ethylene as they ripen.[6]
