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.
I have to admit, I never even knew that purple tomatoes exist. 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 tomatoes were first bred by Professor Jim Myers at the University of Oregon, during a graduate study about the health benefits of tomatoes. When they discovered that purple tomatoes contained anthocyanin, which also provides color to blueberries, they decided to cross them with some wild red ones. Eventually, they came up with a black strain.
