黑蕃茄見過嗎？
看個新鮮有趣的,
妳相信蕃茄也有黑色的嗎?
而且還可以吃喔!

黑色蕃茄 見過嗎？

　　
以色列培育的雜交蕃茄，名為「黑色星系」，含有與藍莓類似的色素，營養價值可能超過普通蕃茄

　　以色列園藝家培育出怪異的黑皮蕃茄，名為黑色星系。為了培育這種「黑色星系」的蕃茄，育種人員讓野生蕃茄與人工種植的蕃茄進行雜交。「黑色星系」的黑皮源自於一種色素，與在藍莓中發現的色素類似。這種色素對光線較為敏感，也就是說，暴露在陽光下的時間越長，「黑色星系」的皮越黑。

　　「黑色星系」由致力於生產雜交蔬菜的 Technological Seeds 公司培育。公司的一位農戶表示：「除了顏色怪異外，這種蕃茄還含有抗氧化劑。」Technological Seeds 指出「黑色星系」的營養價值可能更高，含有大量抗氧化劑和能夠增強免疫系統的維生素C 。

　　「黑色星系」是野生蕃茄和人工種植的蕃茄的「混血兒」，由於顏色奇特，將主要面向豪華酒店。一年內，它們便有望進軍當地市場。此外，無籽檸檬、一種草莓新品種、紅檸檬以及由黃色、紫色和粉紅色構成的彩虹色胡蘿蔔亦將陸續推出上市。

That’s neither a plum nor a tiny eggplant. It’s a brand new breed of tomato: a black one.

Developed by Technological Seeds DM, an Israeli-based company, the “Black Galaxy” variety of tomato gets its color from a pigment found in blueberries, which was not present in its genome before, according to Y Net News. This photosensitive pigment will get darker and darker as the tomato ripens.
Watch the Associated Press report on these black fruits — yes, tomatoes are technically a fruit:

And believe it or not, this black tomato is not the first to be introduced this year with an unusual color. The KVAL reporting out of Corvallis, Ore., states that the “Indigo Rose” tomato was recently announced from a program at Oregon State University. Perhaps the OSU tomato , as KVAL describes, is “really, really purple” but it can at times it appear black.

Purple Tomato with Snapdragon Gene to Fight Cancer
By inserting two genes from a snapdragon into a tomato, British researchers breed purple tomatoes to fight cancer.
The snapdragon genes caused the fruit to produce high levels of anthocyanins, plant chemicals that give blackberries and blueberries their deep purple colour.

Research suggests that the compounds protect against certain cancers, as well as heart disease and age-related degenerative conditions such as Alzheimer's.

They may also combat inflammation, improve vision and hinder obesity and diabetes.
Both the skins and the flesh of the tomatoes are an intense deep purple colour.

The purple tomato is a result of genetic manipulation intended to increase the amount of beneficial chemicals in the fruit. The colour is a side-effect.
Scientists added two genes from the snapdragon flower to the tomato, which is already rich in antioxidants such as lycopene and flavonoids. Fried tomatoes cooked in olive oil are considered one of the best sources of lycopene.
While it has long been known that tomato paste offers protection against various diseases, the new purple tomatoes are said to be twice as healthy as the old-fashioned red variety.
Indigo Rose
Horticulture professor Jim Myers explains to KVAL that the tomatoes take on a purple pigment because of a compound called anthocyanins:
“It is the first improved tomato variety in the world that has anthocyanins in its fruit,” he said.
“If you want a really, really purple tomato that can be as black as an eggplant, give Indigo Rose a try,” Myers said. “Other so-called purple and black tomatoes have the green flesh gene, which prevents normal chlorophyll breakdown. A brown pigment called pheophytin accumulates and has a brownish color that makes a muddy purple when combined with carotenoids.”
Anthocyanins are in the class of flavonoids – compounds found in fruits, vegetables and beverages – that have aroused interest because of their potential health benefits. “They have many varied effects on human health, but while they are powerful antioxidants in the test tube, we don’t really know whether they have an antioxidant effect in the human body.”

Indigo Rose still has a pink interior.
Would you give either of these tomato varieties a try?
