From June 17th to 27th, it was the National Food Safety Promotion Week. On June 14, the relevant authorities approved the issuance of three insect-resistant soybean CV127 and Monsanto Far East Co., Ltd., which were applied by BASF Agrochemical Co., Ltd., for application of the insect-resistant soybean MON87701 and the insect-resistant herbicide-tolerant soybean MON87701×MON89788, which can be imported for processing. The raw agricultural genetically modified organism safety certificate once again detonated the discussion on the safety of genetically modified foods. Genetically modified foods far away from us? Is it an angel or a devil?
Popular Science: About 81% of the world's soybeans are genetically modified products
The International Agriculture and Biotechnology Application Service Organization (ISAAA) released its annual report, saying that in 2012, the global acreage of genetically modified crops reached approximately 170 million hectares, an increase of 6% over 2011. According to the planting area statistics, about 81% of the world's soybeans, 35% of corn, 30% of rape and 81% of cotton are genetically modified products.
According to Cui Zhimin, associate professor of the School of Chemistry and Environmental Engineering at Wuyi University, the use of modern molecular biological technology to transfer genes of certain organisms to other species and transform the genetic material of organisms into shapes, nutritional quality, and consumer quality. Other aspects change to the goals people need. "The food processed with genetically modified organisms as direct food or raw materials is GM foods, and genetic engineering methods are not used. Natural species or processed foods are non-genetically modified foods."
Cui Zhimin said that genetically modified foods will undergo changes in shape, nutritional quality, etc., to meet people's needs. The difference with non-genetically modified foods is soybean. For example, genetically modified soybeans have enhanced anti-virus and cold-resistance, and production will increase. , fat content will be higher, but this may have a negative impact on the human body, so genetically modified foods will be social resistance, there are many manufacturers who advertise themselves as non-genetically modified foods to attract consumers, "There is no evidence It can prove that genetically modified crops cause harm to the human body, but it should be used with caution."
Bigger labels non-transgenic
Small words marked transgene
According to the "Administrative Measures on the Labeling of Agricultural Genetically Modified Organisms," Transgenic Plants and Animals need to be directly labeled "Transgenic × ×," and direct processed products of genetically modified agricultural products are marked as "Transgenic × Processed Products (Finished Products)" or "Processed Raw Materials are Transgenic ××". The labeling of genetically modified organisms should be obvious and be designed and printed at the same time as the packaging and labeling of the product. It is difficult to mark the agricultural genetically modified organisms on the original packaging or labeling. The genetically modified organisms may be attached to the original packaging or label, but the additional labeling shall be firm. If it is persistent, unmarked or not marked as required, it may not be imported or sold.
However, when the author visited the market, he found an interesting phenomenon. On the packaging of goods, all the words with “non-transgenic†words used large fonts, conspicuous positions, eye-catching colors, and “transgene†was forced to Go to the corner. In Yibai Department Store, the author in the edible oil selling area, Lu × card has hit the "non-genetically modified" brand, and put two brands on the shelf on which the merchandise is placed, which reads "non-genetically modified" and another brand of Fu × The door edible oil is also marked in the bottle with the words "non-genetically modified press". The author turned around in the supermarket and found that most of the edible oils sold in the supermarket were non-genetically modified. In a corner, a bottle of 2.5L of Fu* Tune Oil was found in the bottle. In the last column, the words “Soybean oil processing raw materials are genetically modified soybeans†and “Rapeseed oil processing raw materials are genetically modified rapeseeds†are written in small letters.
In terms of prices, the author found that the difference between the prices of genetically modified and non-genetically modified edible oils was not significant, and the price difference between different brands was prominent. In the supermarket, the prices of 5L natural edible oil and non-genetically modified edible oil processed by “non-GMO raw materials†are 66.8 yuan and 77.9 yuan, respectively, while the price of the same brand of 2.5L genetically modified edible oil is also 36 yuan. The salesperson in charge of the district said that people rarely buy genetically modified products when choosing edible oils, and those with higher cost performance are more popular with the public. "But of course it's better to eat non-genetically modified and more natural."
â— Recommendation: Do not have to fear GM foods
According to the annual report issued by ISAAA, the planting area of ​​genetically modified crops in China is about 4 million hectares, ranking sixth in the world, and the vast majority of them are transgenic insect-resistant cotton (accounting for 80 percent of China's cotton planting area. %), there are a small amount of papaya, tomatoes, bell peppers and so on. In addition, according to media reports, in 1996, China became a major importer of soybeans. The annual import of soybeans was 1.1 million tons, and in 2010, the data has soared to about 50 million tons. The vast majority of imported soybeans are genetically modified soybeans, and the price is higher than that of the countries each year. The prices of domestically-produced soybeans collected and stored are 0.3 yuan to 0.4 yuan lower.
"The damage of genetically modified foods is not observed two days or two in a day. It may take a hundred or two hundred years to become apparent. Moreover, genetically modified foods are harmless in the end. Their scientific implementation is still inconclusive, so citizens have not It is necessary to panic," said Cui Zhimin.

â— Non-genetically modified soybeans:
It is elliptical in shape and somewhat flat. The navel is light brown. Beans vary in size. The milk soaked out is milky white
â— Genetically modified soybeans:
Round, round. The navel is yellow or tan. The size of beans is almost the same. The soymilk is a bit yellow, and the tofu made with this bean is a bit yellow.
â— Simple test method:
With water testing, native soybeans will germinate in water for three days, and the genetically modified soybeans will not germinate, but only the individual will swell.
