This new type of tomato could significantly boost the nutritional value of everyday meals.
A groundbreaking development in agriculture has led to the creation of a purple tomato, rich in anthocyanins—powerful antioxidants also found in blueberries and cranberries. This unique pigment is the result of transferring a gene from snapdragons into the tomato, enabling it to produce these beneficial compounds. Researchers believe that this innovation could enhance the health benefits of common foods like ketchup and pizza, making them more nutritious without changing their taste or texture.
The project was successfully carried out at the John Innes Centre in Norwich, England. Professor Cathie Martin, the lead scientist behind the research, hopes that the first harvest will allow further investigation into the potential applications of these tomatoes. “You can get the same compounds that are found in blueberries and cranberries from purple tomatoes,†she explained. “Adding them to widely consumed foods could make these nutrients more accessible and affordable for everyone.â€
Despite being developed in the UK, the European Union’s strict regulations on genetically modified organisms (GMOs) have made it challenging to bring such products to market. As a result, Professor Martin turned to Canada, where regulations are more favorable toward GM technology. She has partnered with Ontario-based farms to cultivate the tomatoes in a 465-square-meter greenhouse, aiming to scale up production and eventually bring the product to consumers.
Professor Martin envisions the purple tomato as a revolutionary food that can help change public perception about genetically modified products. “I hope this can be a pioneering example that shows people how GMOs can actually benefit them,†she said. Researchers are currently conducting tests using tomato juice to determine if the anthocyanins have positive effects on human health. Early studies on mice have shown promising results, including anti-inflammatory and cancer-fighting properties.
However, the challenge remains in shifting public opinion. A major EU survey from 2010 revealed that the ratio of opponents to supporters of GM products was roughly 3 to 1. Professor Nick Pidgeon, an environmental physicist at Cardiff University, believes that mistrust from past incidents, such as the mad cow disease crisis, still influences people's views. “Highlighting the benefits of genetically modified products could help change this perception,†he said.
Looking ahead, Professor Martin aims to introduce purple tomato juice to North American consumers within the next two years. With continued research and public education, she and her team hope to see genetically modified products gain more acceptance and recognition for their potential to improve health and nutrition on a global scale.
