Food ingredients can be processed to remove all DNA or protein, including those that have been changed by genetic modification. An example is canola oil from a genetically modified canola plant. The oil from this genetically modified canola plant can be the same as oil that comes from a canola plant that has not been modified. When food has been processed to remove all genetically modified DNA or protein, and does not have altered characteristics, the food does not need to be labelled as GM. Meat and other products from animals that have been fed GM food are not labelled as genetically modified.作者: oldid 时间: 2013-8-28 11:43:48
