| Genetically modified produce has come a long way since the 1994 introduction of the Flavr Savr, the first genetically modified crop commercialized for human consumption. The GMO tomato was engineered to have a longer shelf life than conventionally bred versions, but it was expensive to produce and distribute and was discontinued after a few years. As Emily Mullin reports, a new genetically modified tomato will soon arrive in US stores, this one modified to enhance its flavor and health benefits. Norfolk Plant Sciences, the company developing the tomato, plans to introduce a purple cherry tomato in test markets in 2023. It's also working on purple tomato juice, sun-dried tomatoes, and beefsteak tomatoes, plus plans to sell seeds for backyard gardeners. The tomato gets its vibrant hue from the addition of two genes from the snapdragon flower. Those genes act like a switch to turn on the production of anthocyanin, an antioxidant-rich pigment found in blackberries and blueberries that may help prevent cancer and protect against developing type 2 diabetes. "This is a trait that is mainly for the consumer," says Bárbara Blanco-Ulate, a fruit biologist and professor at the University of California, Davis, who was not involved in developing the purple tomato. "People want food that is more nutritious and exciting." But will it be enough to win over consumers who are nervous about consuming genetically modified food? Read about the GMO tomato designed to sway health-conscious consumers. |
