Shanghai World Expo 2010Ministry of science and technology has been genetically modified ingredients and pathogens, toxic and harmful substances, listed as a threat to the health of three prohibited food life. And the organization of national science and technology strength and resource of science and technology, research and development of GM testing equipment, avoid to visit the World Expo foreigners eating genetically modified food, at least a little, in China's large-scale promotion of genetically modified crops, is no longer a question of understanding, we are very clear own are doing -- whether mandatory promotion or be compulsory recipients -- know what the end is. Genetically modified food safety has been the existence of great controversy, there is no consensus. It exists only in the short period of 10 years, many of the long-term effects are can make nothing of it, eating genetically modified food as regards himself as the white mouse, with unpredictable risks. Therefore, the genetically modified food should adopt the precautionary principle, in the long-term safety has not been fully defined before, should not be used in food production of genetically modified raw materials. At present, most people are reluctant to eat genetically modified food, but genetically modified food is everywhere, we cannot predict the technique brought about disastrous consequences, but we know the damage is irreversible. The Ministry of agriculture of China has approved the cultivation of genetically modified crops are: sweet pepper, tomatoes, potatoes; staple crops are maize, rice. That may in the future have approved the crops are wheat, sweet potato, peanut and other. Imports of genetically modified food with soybean oil, rapeseed oil, soybean. At present only the peanut oil is not genetically modified. Macdonald, KFC food basic all is a genetically modified. Pigs, cattle, chicken feed is corn, transgenic soybean. Transgenic soybean is the No. 6light gasoline leaching. Need to be wary of several well-known" genetically modified soybean oil" brand! 1, golden dragon fish, soybean oil, salad oil, blend oil market share of about 40%, the capital of Singapore Wilmar International Chinese Guo Henian family + American ADM company;2, numbers, soybean oil, salad oil, blend oil market share of about 30%, the management to state-owned COFCO set group + Singapore Wilmar International + American ADM company; in addition, the current local edible oil brand still hundreds, most in order to reduce the cost, using genetically modified soybean oil, but the market share of small, when buying can see Mark, such as" this product is a genetically modified soybean oil, Brazil soybean, leaching" and other words the need for the purchase, please be careful. Genetically modified food differential knowledge:1, soybean soybean: an elliptical shape, a flat. The umbilicus is light brown. Bean of different sizes. Out of the soybean milk is milk white. Transgenic soybean: round, round. The umbilicus is yellow or brown. Beans are much of a size. Out of the milk is a bit yellow, the bean bean curd made what are a bit yellow. Simple inspection methods: transgenic soybean germination can not water!! native soybean soaked in water for three days will not germinate sprout! Transgenic soybean, only individual expansion. From the germination process, people can discover, these transgenic soybean is disposable produce fruit, its germ is the essence of life activity, therefore, there is no continuation of the ability of offspring. The equivalent of one person can be a normal pregnancy, but each time was stillborn, this means that the continuation of life so far. Then humans if the mass of the long-term consumption of a variety of genetically modified food, which harms the human transgene fragments, will inevitably influence character by environment influence human itself until changed the normal gene, decreased resistance to disease, tufted, or loss of fertility is reasonable. 2carrots transgenic carrot: uneven surface, generally not too straight, from head to tail is from coarse to fine. And the head is outside protruding out of the. Transgenic carrot: surface is relatively smooth, generally straight, its tail is thicker than the middle sometimes. And the head to the concave. Note: carrot only in autumn and winter seasons, summer general is a genetically modified. 3potato non transgenic potatoes: look more ugly, generally darker in color, with craters, and skin color and irregular, peeling, its surface will soon become darker in color, skin is white. Transgenic potatoes: smooth surface, with very shallow, light color. After the surface peeling, no obvious change. Test method for Peel first: after watching the changes and decide to eat do not eat. 4maize transgenic maize: sweet and crisp, full, beautiful shape, head tail almost particles. 5rice in China to obtain the legal right of transgenic rice planting region of Hubei was, to guard against the elongated bright meters. Easy and northeast" long grain," confusion. When you buy a must see the origin. 6tomato Transgenic Tomatoes: the color red is very good, the fruit is hard, not easy to crack. 7, other differential method of imported fruit labels. Generally speaking, in the bottom of the printed label general export country name, Middle English letters indicating the name of fruit, to the top of the English alphabet identifies the export enterprises of. Tabs at each intermediate generally have4 Arabia Digital:3word at the beginning of the representation is sprayed. 4the beginning of the word representation is a transgenic fruits;5the beginning of the word representation is a hybrid fruit. (1) the supermarket to buy food must be careful, first check whether there is a transgenic labeling. According to" agricultural genetically modified organisms identity management approach", genetically modified food should be marked. But these annotations are afraid that people, small to only 1.8mm high, and hide in the most unlikely place, carefully check can always be found. (2) the supermarket tomatoes, most of transgenic papaya, resolutely do not buy. From safety and quality, individual farmers peddle fruits food supermarket is much better than. Especially not superstition foreign supermarkets, where things are good and not good, bad, not too much. (3) the use of genetically modified maize the earliest, most widely, the most, the purchase of any corn food were to be cautious, even supermarkets sell corn buns. (4) transgenic wheat white and transparent shiny, the horny, belongs to hard strong gluten bread wheat varieties, excellent transgenic wheat in Anhui since20089506, flour and bleaching agent, talcum powder mixed inside, it is more difficult to identify. (5) rice transgenic Chinese had done several years, a few into the market, we should be especially vigilant is long and thin and bright rice. Northeast of rice at present no genetically modified, may temporarily ease, must look at the outer packaging bags, such as Heilongjiang, Jilin and Liaoning rice, northeast rice is rice, short round type, and the Hubei, Hunan area planting of transgenic rice plants ( such as BT Shanyou 63in ) long grain type has substaintial distinction, easy to identify. In addition, the Thailand ban on genetically modified rice, no problem. (6) the millet, oats, buckwheat, sorghum is the minor grain crops, also too late to GM. Earthnut is our country unique products, no transgenic, sweet potato is not genetically modified.
