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.
Are purple tomatoes genetically modified?

Are colored tomatoes genetically modified?
Tomatoes have increased levels of antioxidant
A new purple tomato might be hitting grocery stores next year. The tomato has been genetically modified by Norfolk Plant Sciences to alter its color and enhance its nutritional quality.
Where do purple tomatoes come from?
Cherokee Purple seeds, originating from Tennessee, are thought to have been passed down from Native Americans of the Cherokee tribe. This heirloom tomato variety consistently ranks very high in taste tests. Slice Cherokee Purple tomato for rich, dark color and unmatched sweet, rich taste on sandwiches or in salads.
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 there GMO tomatoes on the market?
The answer is no, while there may be an ‘m’ and two ‘o’s, there are no ‘GMOs’ in ‘tomato’. Put simply, you can’t compare GMO vs non-GMO tomatoes because there is no such thing as a GMO tomato.
Are black tomatoes GMO?
SB is the result of a breeding programme and it is not a genetically modified (GM) product. We report the chemical characterization and structure elucidation of the attractive anthocyanins found in the peel of SB tomato, as well as other bioactive compounds (carotenoids, polyphenols, vitamin C) of the whole fruit.
What foods are genetically modified?
Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism.
Why are tomatoes genetically modified?
Tomatoes are used as a model organism in scientific research and they are frequently genetically modified to further understanding of particular processes. Tomatoes have been used as a model in map-based cloning, where transgenic plants must be created to prove that a gene has been successfully isolated.
What do purple tomatoes taste like?
They’re very sweet and have a rich, almost smoky flavor. The fruit is large and refreshingly acidic, thick-skinned with an earthy, lingering flavor.
Do purple tomatoes taste different?
As for taste, tomato lovers all have their preferences, and various factors — such as location, weather and temperature — can have an impact. Anthocyanins don’t have a noticeable flavor of their own, and the purple color doesn’t affect this tomato’s taste.
What is the purpose of purple tomato?
The purple tomato contains higher levels of anthocyanins — an antioxidant compound with the potential to help prevent cardiovascular diseases and fight cancer. Anthocyanins also slow down the fruit’s rotting process and doubles its shelf life.
How long have purple tomatoes been around?
History. In 1990 John Green of Sevierville, Tennessee mailed heirloom tomato expert Craig LeHoullier seeds of an unnamed purple tomato. Green said that the tomato had originated with the Cherokees more than 100 years previously.
What do anthocyanins do for the body?
Anthocyanins possess antidiabetic, anticancer, anti-inflammatory, antimicrobial, and anti-obesity effects, as well as prevention of cardiovascular diseases (CVDs) [2]. Therefore, anthocyanins extracted from edible plants are potential pharmaceutical ingredients.
How is corn GMO?
Corn is the most commonly grown crop in the United States, and most of it is GMO. Most GMO corn is created to resist insect pests or tolerate herbicides. Bacillus thuringiensis (Bt) corn is a GMO corn that produces proteins that are toxic to certain insect pests but not to humans, pets, livestock, or other animals.
Are there yellow tomatoes?
There are many kinds of slicing tomatoes, including the large, globular-shaped beefsteak tomato, which can also be yellow in color. Several popular Yellow tomato varieties include lemon boy, earl of edgecombe, dixie golden giant, and Dr. Wyche’s Yellow tomato.
How do you tell if a tomato is genetically modified?
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. (
Which tomatoes are not GMO?
Heirloom tomato seeds are never GMOs, and they are also never hybrids. The plants are often hardier than non heirlooms, and the tomatoes tend to taste better.
What is the most genetically modified fruit?
papaya
PRSV-resistant papaya is the most widely cultivated genetically engineered fruit, followed by Bt eggplant, virus-resistant squash, Arctic® apples, and Pinkglow™ pineapple.
Are black tomatoes natural?
Nearly all black tomatoes come from the Crimean peninsula in the Ukraine, where they’ve been favorites of the locals for more than a century. Hot summers there built pigment and fruit sugars that turn flesh and skin dark shades of mahogany, chestnut, bronze and deep purple.
How do I make purple tomatoes?
Two genes were taken from another plant (the snapdragon) and added to a type of purple tomato. The genes amplified the plant’s ability to produce anthocyanins, resulting in a unique tomato with richly purple-colored flesh.
