转基因胡萝卜：表面相对较光滑，一般是 直的，它的尾部有时比中间还粗。且头部
是往内凹的。 非转基因胡萝卜：表面凸凹不平，一般不 太直，从头部到尾部是从粗到细的。且头
部是往外凸出来的。 注：胡萝卜只有在秋冬季节有，夏季的一

中国的转基因作物
中国政府十分重视生物技术的研究，中国正在研发的 转基因作物和林木有47种，涉及的基因种类超过100 种。特别是在转基因抗虫棉、转基因水稻等领域的研 究成果已居世界前列， 2002年，我国转基因作物种 植面积突破210万公顷。
从1997年至2003年，农业部已批准水稻、玉米、棉花、 大豆、油菜、马铃薯、杨树等10种转基因植物进入田 间释放，并批准转基因棉花、番茄、甜椒、矮牵牛花 等6个转基因品种进行商业化种植。但转基因食品所 占的比例很少。

转基因大豆：为椭圆形状，有点扁。肚脐为黄褐 色；豆粒大小不一。打出来的豆浆为乳白色。 非转基因大豆：为圆形，滚圆。豆粒大小差不多。 打出来的豆浆有点黄，用此豆制作的豆腐什么的
都有点黄色。 简单的检验方法：可以用水检测，本土大豆用水 浸泡三天会发芽；转基因大豆不会发芽，只不过
是个体膨胀而已。 如果你家里正好有大豆，拿出来鉴别一下，是转
石粉混在里面，就更难识别。 （5）小米、燕麦、荞麦、高梁均属小宗粮食作 物，还来不及去转基因。花生是我国独特产品， 暂无转基因，红薯也未转基因。通过以上这几个 简单的识别法来鉴别一下，平时去超市菜场购买

3.Microorganisms
Although GM microorganisms and ingredients produced from them (e,g,GM chymosin in cheese making) have been available for many years, use of GM bacteria and yeasts in foods and in food production has been limited. Many applications are possible, including improvement of traditional food fermentations, production of a variety of metabolic end products, and development of bacteria with enhanced probiotic and other health benefit properties.
Pros and cons of GM food
1. Advantages
Increase crop yields;
Reduce production costs; Enhance crop resistance to pests and virus, Improve agricultural resistant storability; Shorten crop development time; Get rid of the Four Seasons supply; Break down species barriers, Cultivate new species, Produced conducive foods to human health .
