Antioxidants Found in Tomatoes can More than Double their Shelf Life: Study
A recent study has revealed that the shelf life of tomatoes can be increased to more than double from the antioxidants found in purple GM tomatoes.
The study averred that the natural pigment can help in keeping the tomatoes fresh and tastier for 48 days instead of the normal shelf life of 21 days. The researchers found that the pigment slowed down the over-ripening process of the fruit.
This makes it tastier as it becomes rotten and soft. Published in the journal Current Biology, the research has suggested that anthocyanins help in the gifting a longer and healthy life to the red fruit, which is often considered as a vegetable.
The research has led to change in the way which tomatoes were produced. Now the scientists are considering the fruits with highest quantity of the antioxidants to be used as parental lines for breeding. The results from the research could also be used to benefit the other soft fruits like strawberries and raspberries.
"Working with GM tomatoes that are different to normal fruit only by the addition of a specific compound, allows us to pinpoint exactly how to breed in valuable traits", said Professor Cathie Martin from the John Innes Centre, who took part in the research.
