According to this article scientists have created a tomato that can stay fresh for up to six weeks. The tomato which is the result of genetic engineering will stay fresh for around 45 days, three times longer than a normal tomato. Researchers believe the process could also be applied to other fruits including bananas and mangos. It has been created by researcher in India who have managed to stop the production of ripening enzymes in the fruit. The increased firmness stops the fruit going soft for longer. The one problem may be that no one has yet tested the tomato for taste. It would also need to undergo extensive safety testing before it would be allowed to go on sale. I’m not convinced myself, I find fruit and vegetables at their best when they are fresh and am a little dubious at something that can be kept so long.
