Grown in Costa Rica, it took 16 years to perfect and is in high demand. Its distinct pink coloration comes from a pigment called lycopene, the same carotenoid that gives watermelon and tomatoes their red hue. In standard pineapples, an enzyme called lycopene beta-cyclase converts lycopene to beta-carotene, resulting in yellow flesh. In Pinkglow pineapples, this enzyme is muted through a technique called RNA interference, causing lycopene to accumulate instead. The genetic modification began in 2005 and involved testing four generations of the plant between 2010 and 2014 to ensure quality and productivity. Del Monte has patented this pineapple, making them the sole producers. The retail cost is notably higher due to its scarcity and marketing, ranging from $10 in grocery stores to up to $39 online.
