转基因食品的研究已有几十年的历史了,不过甚嚣尘上还是最近几年的事。所谓转基因食品就是将某些生物的基因转移到其他物种中去,改造生物的遗传物质,使营养品质、消费品位随人类所需的目标转变。那么,转基因食品与一般食品有何不同呢?其实都是一样,都含有氨基酸、蛋白质和碳水化台物以及其他物质,但转基因食品的优点已经超过了一般食品。例如,美国普遍种植的转基因玉米,色氨酸的含量已提高了30%,色氨酸 Genetically modified food has been in the research for decades, but it has only been rampant in recent years. The so-called genetically modified foods is the transfer of certain biological genes to other species to transform biological genetic material, so that nutritional quality, consumer tastes with the desired goal of human change. So what is the difference between genetically modified foods and general foods? They are all the same. They contain amino acids, proteins, carbohydrates and other substances. However, the advantages of genetically modified foods have surpassed those of ordinary foods. For example, GM corn grown in the United States generally has a tryptophan content of 30%, tryptophan
