They taste wonderful!

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.  That’s why black tomatoes do well in southern states with torrid summers.  They taste good up North, too, but colors are paler.

The ‘Indigo Rose’ is a new, strangely-colored variety of tomato. The fruit is jet black on the outside and juicy purple-red on the inside. These colors might not sound very appealing, but black tomatoes are supposed to be very tasty, and most importantly, rich in antioxidants. Indigo Rose is a cross-breed between red and purple tomatoes, and is the latest ‘superfood’ to hit the market.
The modified fruit, bred by scientists in America, contain a special antioxidant called anthocyanin. Anthocyanin is responsible for fighting diseases like diabetes and obesity, and is the main pigment that lends the tomato its purple color. And when the purple tomatoes are mixed with the regular red ones, the resultant breed turns out black.
Black tomatao are healthier than normal red varieties.
Unusual color of this vegetable is coming from the black pigment, which is produced when exposed to sunlight.
They found some tomatoes with purple pigmentation and tests revealed that anthocyanins were providing the colour, the same as blueberries.
Black tomato has great potential to prevent the expansion of cancer in the body because it contains Anthocyanin. Anthocyanin is an antioxidant which kills cancer’s cells. It was firstly breaded in the UK.
The fruit is among the first in the world to contain anthocyanins, an antioxidant believed to help fight cancer, diabetes and obesity.
Ray Brown, 66, who runs Plant World Seeds, first came across the unusual fruit when a customer sent him a mystery package entitled ‘black tomato‘.

— I thought it was a joke, but when I planted the seeds and fruits grew I was very surprised by the production, says Ray
The taste of this kind of tomatoes is very strong, but this is a very healthy vegetable, which has yet to be investigated. After researching this vegetable there will certainly emerge many health benefits.
People are passionate about their tomatoes,” he added, while commenting on the taste of the black variety. “The purple color draws their interest and because it’s extraordinary, people tend to expect impressive flavor as well. It does have a good balance of sugars and acids and tastes just like a tomato. Anthocyanins are essentially tasteless.
During the growth process, these tomatoes start out green and turn black when exposed to sunlight. This is because the anthocyanins get produced in the fruit only when light touches the surface. “If you pick an Indigo Rose and expose the non-purple area to sunlight, it will turn purple in about a week”.
But he cautioned planters against picking the fruit too soon – it needs to ripen fully for complete development of sugars and acids. In the State of Oregon, the average first ripe date is about 91 days after planting. These black tomatoes are not GMO (genetically modified organisms).
