Purple tomatoes have been developed by inserting two genes from snapdragon, a flower, in tomatoes to grow purple tomatoes that have health protecting anthocyanins.
Are purple tomatoes genetically modified?
The tomatoes are genetically modified, designed by researchers at the UK’s John Innes Centre to be packed with anthocyanins, the purple pigment that gives blueberries their hue, says the CBC. Purple tomatoes fit an increasingly popular food maxim: the more colorful the food, the better it likely is for you.
How were purple tomatoes genetically modified?
The purple pigment is the result of the transfer of a gene from a snapdragon plant – the modification triggers a process within the tomato plant allowing the anthocyanin to develop.
What makes purple tomatoes purple?
What causes the purple pigment? A class of compounds generally called anthocyanin. The specific anthocyanins present in the tomatoes are mainly petunidin, but malvidin and delphinidin are also present. The anthocyanins are modified by the presence of acyl (sugar) groups.
Are purple tomatoes natural?
Blue tomatoes, sometimes referred to as purple tomato, are tomatoes that have been bred to produce high levels of anthocyanins, a class of pigments responsible for the blue and purple colours of many fruits, including blueberries, blackberries and chokeberries.
Who invented purple tomato?
Cathie Martin
The purple tomato was created by Cathie Martin at the John Innes Centre in the UK. In 2008, her team reported that mice whose diet was supplemented with purple tomato powder lived nearly 30 per cent longer than those on a standard diet or a diet supplemented with powder from normal tomatoes.
How do I know if my tomatoes are GMO?
Identify how produce is grown by reading its label or sticker number.
- 4-digit number means food was conventionally grown.
- 5-digit number that begins with a 9 means produce is organic.
- 5-digit number that begins with an 8 means it is genetically modified. (
What are the disadvantages of genetically modified tomatoes?
Various Cons of Genetically Modified Organisms (GMO’s)
- They might contribute to a rise in allergic reactions.
- Genetic food can prompt allergic reactions from different foods.
- GMOs may contribute to antibiotic resistance.
- Some research has linked GMOs to cancer.
- Very few companies are in charge of all the GMO seed market.

Are black tomatoes GMO?
This “Indigo Rose” black tomato is high in beneficial anthocyanins, an anti-oxidant which is thought to potentially help fight cancer as well as diabetes and obesity. It’s an open pollinated tomato developed at Oregon State University using conventional plant breeding and is NOT GMO.
Are purple tomatoes healthier?
The antioxidant capacity in tomato purple fruits is higher than in non-anthocyanin tomatoes and their healthy role has already been demonstrated in both in vitro and in vivo studies.
What is the benefits of purple tomatoes?
Anthocyanins offer protection against certain cancers, cardiovascular disease and age-related degenerative diseases. There is evidence that anthocyanins also have anti-inflammatory activity, promote visual acuity and hinder obesity and diabetes. Tomatoes already contain high levels of the antioxidant lycopene.
Do purple tomatoes have lycopene?
CRF from peel of Purple tomato contains lutein, lycopene, and β-carotene up to 6, 1.5, and 2.5 times more than that of Red Cherry and it exhibited the highest antioxidant activity at 400 μg/mL, reaching 82% and 97% in DPPH and ABTS•+ assays, respectively.
Do blue tomatoes exist?
Blue tomatoes aren’t new but the varieties today have a great taste as well as healthy benefits. They get their blue color—more of a deep purple-black—from the high levels of anthocyanin found in their skin which is a powerful anti-oxidant.

Is broccoli a GMO?
Broccoli IS NOT, I repeat, IS NOT considered a genetically modified organism (GMO). If you want to sound even smarter than you already are, refer to broccoli as the product of selective breeding. In short, by controlling the environment, and taking buds from the wild cabbage, broccoli can be forced to reproduce.
