This new tomato can improve the nutritional value of our daily diet.

(passenger/compiler) Purple pigment is the result of transfer of a gene from snapdragon that results in the production of anthocyanins in tomatoes. This pigment, called anthocyanin, is an antioxidant and animal studies have shown that it can help fight cancer. Scientists claim that this new type of tomato can improve the nutritional value of ketchup, pizza, and other foods. The tomato was successfully cultivated at the John Innes Centre in Norwich, England. Professor Cathie Martin hopes that the first tomato harvest will allow researchers to investigate its potential use. She said: “You can get the same compounds that blueberries and cranberries contain from purple tomatoes. You can add them to the foods that people eat in large quantities, and you can afford them all.”

Although the invention came from the United Kingdom, Professor Martin claimed that the European Union's restrictions on genetically modified crops led her to turn to foreign technology for the development of this technology. Canadian regulations are more supportive of GM technology, and Professor Martin signed contracts with Ontario and New Energy Farms to grow enough purple tomatoes in a 465-square-meter greenhouse.

Prof. Martin said: “I hope this type of tomato can be used as a pioneering product to make people understand this kind of genetically modified product that is beneficial to them.” Researchers will use juice to conduct a series of tests, including checking whether anthocyanins have positive effect. Early studies have shown that it has anti-inflammatory and cancer-reducing effects in mice. The key question is whether the health benefits of genetically modified products will affect public opinion. An important EU survey in 2010 found that the ratio of opponents to supporters for GM products is approximately 3:1.

Professor Martin hopes that purple tomato juice can be sold to consumers in North America within two years. She and other British researchers hope that GM products will emerge in a more positive manner. Professor Nick Pidgeon, an environmental physicist at Cardiff University, has conducted opinion surveys and panel discussions on GM and other technologies. He claimed that: “The mistrust left over from the era of mad cow disease will lead people to continue to worry. Highlighting the benefits of genetically modified products will change this.”
