But what gives this genetically engineered tropical fruit its rosy hue? The flesh is made pink thanks to an extra helping of lycopene, a carotenoid and pigment that occurs naturally in pineapples. It's also the compound that gives watermelon and tomatoes their reddish color.
In pineapples, lycopene is usually converted to beta-carotene by an enzyme, which makes the inside of the pineapple yellow. That enzyme, lycopene beta-cyclase, is muted in the pink pineapple, and this causes lycopene to accumulate, according to Del Monte's patent on the new fruit. Because Del Monte has claimed the pink pineapples as intellectual property, it is the only company allowed to grow them.
