英国科学家已经成功培育出一种紫色转基因西红柿,紫色素是将金鱼草中的一种基因转移过来的结果,这种修改导致西红柿内产生了花青素。这种被称作花青素的色素是一种抗氧化剂,针对动物的研究表明它能够帮助抵抗癌症。科学家声称,这种新型西红柿能够改善番茄酱、披萨饼等食品的营养价值。 British scientists have succeeded in cultivating a purple tomato genetically modified tomato, purple pigment is a result of the transfer of a gene in snapdragon, this modification led to the production of anthocyanins in tomatoes. This anthocyanin-based pigment is an antioxidant and animal-based research shows it helps fight cancer. Scientists claim that this new type of tomato can improve the nutritional value of foods such as ketchup and pizza.
