The prospect of genetically modified purple tomatoes reaching the shelves has come a step closer.
Their dark pigment is intended to give tomatoes the same potential health benefits as fruit such as blueberries.
Developed in Britain, large-scale production is now under way in Canada with the first 1,200 litres of purple tomato juice ready for shipping.
The pigment, known as anthocyanin, is an antioxidant which studies on animals show could help fight cancer.
