on a visit to Big Eagle, my native grocery retailer in Pittsburgh, I seen one thing new within the fruit part: a single pineapple wrapped in a pink and inexperienced field. The picture on the entrance panel confirmed a pineapple lower open, revealing the pink flesh. The fruit touted because the “jewel of the jungle” was the Pinkglow pineapple, a creation of US meals big Contemporary Del Monte. It value $9.99, a bit greater than double the worth of a daily yellow pineapple.
I put the field within the cart, took a photograph on my cellphone, and shared the discover with my foodie buddies. I discussed that its colour was the results of genetic modification – the field mentioned “made doable by bioengineering”, however that did not appear to hassle anybody. After I introduced my Pinkglow to a Tremendous Bowl celebration, folks drooled over the colour after which wolfed it up. It was juicier and fewer tart than a daily pineapple, and there was one other distinction: it had a particular crown lower off. Quickly my buddies began shopping for pink pineapples too. One used Pinkglow to make selfmade tepache, a fermented pineapple peel drink that was invented in pre-Columbian Mexico.
At a time when orange cauliflower and white strawberries are actually commonplace in American grocery shops, a non-yellow pineapple does not appear so misplaced. Nonetheless, I questioned why now with the flashy presentation? And why pink? And why did my buddies and I take it straight away?
My inquiries to Hans Sauter, Contemporary Del Monte’s chief sustainability officer and senior vice chairman of analysis and growth and agricultural companies, he started with a short historical past of the fruit. Chances are you’ll assume, as I do, that pineapples have all the time been candy and sunny, however that wasn’t the case till the Nineteen Nineties. Retailer-bought pineapples of yesteryear had a inexperienced pores and skin with gentle yellow flesh that was typically extra tart than candy. Shopping for contemporary was a little bit of of venture. “Nobody might inform for positive whether or not the fruit was ripe or not, and pineapples had been largely canned as a result of folks might belief that they might eat them there,” Souter says. The addition of sugar to some canned pineapples made it a sweeter and extra uniform product.
In 1996, the corporate launched Del Monte Gold Further Candy, extra yellow and fewer acidic than something in the marketplace on the time. Pineapple gross sales soared and client expectations of the fruit modified ceaselessly. Gold’s recognition led to a global pineapple feud when fruit rival Dole launched its personal selection. Del Monte sued, claiming that Dole basically stole its Gold method. The 2 firms ultimately settled out of courtroom.
With the success of the pineapple, Gold Del Monte seemed for brand spanking new traits that would make the pineapple much more engaging to customers, Soter says. However breeding pineapples is a sluggish course of; it might take two years or extra for a single plant to supply mature fruit. Del Monte spent 30 years crossing pineapples with sure fascinating traits earlier than he was able to launch Gold. Souter says that ready one other 30 years for a brand new selection “was out of the query.” Due to this fact, in 2005, the corporate turned to genetic engineering.
Del Monte did not got down to produce pink pineapple per se, however on the time, Soter says, there was client curiosity within the antioxidant-rich fruit. (Acai and pomegranate juice, anybody?) Pineapples naturally convert the antioxidant-rich reddish-pink pigment lycopene into the yellow pigment beta-carotene. (Lycopene is what offers tomatoes and watermelon their colour.) Stopping this course of can yield pink flesh and better antioxidants. The corporate tasked its devoted pineapple analysis group with determining how to do that.
The group landed on a set of three modifications to the pineapple genome. They inserted DNA from a tangerine to make it categorical extra lycopene. They added RNA “silencing” molecules to mute the pineapple’s personal enzymes that convert lycopene, which additionally helped scale back its acidity. (RNA silencing is similar approach used to make GMO arctic apples that will not flip brown.) Lastly, Del Monte added a gene to tobacco that confers resistance to sure herbicides, although firm officers say it was performed simply to , in order that scientists can verify that different genetic modifications have taken impact — not as a result of Del Monte plans to make use of these herbicides in manufacturing.
