Some people believe that GM foods are safe and reliable, and some people are reluctant to eat GM foods regardless of how they are certified. Election or no election is everyone’s autonomy. However, in the face of dazzling food, many health-conscious consumers worry. How do you know if you are genetically modified? Is it possible to completely avoid genetic modification in life? Is the method of identifying genetically modified foods that is widespread on the Internet correct? This reporter interviewed related experts. How do you know which foods are genetically modified? --- mainly to see the logo, compared with the U.S. voluntary logo, EU quantitative logo, China's implementation of the directory, qualitative, mandatory logo system Walking into a small supermarket on the Chaoyang Road in Beijing, the reporter saw a variety of brands, types, and packages of cooking oil in the grain and oil region. Blended oil, sunflower oil, gold embryo corn oil, rapeseed oil, a soybean oil, pressed peanut oil ... dazzling occasion, a shopping guide sister came over to recommend a brand of peanut oil. "This kind of oil does not contain genetically modified organisms. It sells particularly well. It is a little pricey." After a closer look, the bottle of peanut oil is strewn with the words “pure physical pressing†and “non-genetically modifiedâ€, and then picks up the same brand of edible blending oil. The product name, ingredient list, shelf life and other product descriptions are the last One line noted: "The raw material for the processing of soybean oil contained in this product is genetically modified soybean." After observing other varieties, the reporter found that any soybean oil or blended oil derived from genetically modified soybeans as raw material for processing was noted in the product description. Huang Dazhao, a researcher at the Institute of Biotechnology of the Chinese Academy of Agricultural Sciences, said that as of now, China has approved and issued seven kinds of security certificates for genetically modified crops, namely, storage-tolerant tomatoes, insect-resistant cotton, change of color petunia, disease-resistant pepper, and disease resistance. Papaya, phytase corn and insect-resistant rice. However, only large-scale commercial production of insect-resistant cotton and anti-viral papaya, resistant pepper and storage-tolerant tomatoes were not accepted by consumers in production, and thus commercialization was not achieved, but insect-resistant rice and phytase corn were not Completion of the follow-up variety certification, no commercial planting. In addition, there are five varieties of soybeans, corn, cotton, rapeseed and sugar beet that are used as raw materials for processing. The number of genetically modified soybeans is the largest. In 2012, China imported 58.83 million tons of soybeans, mostly genetically modified soybeans. These soybeans mainly enter the oil mill as processing raw materials for edible oils. "In order to meet consumers' right to know and choose, China has implemented a strict directory, qualitative, and mandatory labeling system in comparison with foreign countries," Huang Kunlun, a professor at China Agricultural University, told reporters to be included in the catalog of genetically modified markers and marketed. The five major categories of 17 genetically modified organisms need to be identified in China. At present, genetically modified foods such as soybean oil, rapeseed oil and blended oils containing genetically modified components are all identified on the market. . How do other countries regulate the issue of genetically modified genes? Huang Kunlun said that the United States is a major country in the production and application of genetically modified foods. There are more than 3,000 varieties and brands of genetically modified foods such as genetically modified soybeans, corn, canola, tomatoes, and papaya on the market. However, the United States is willing to implement genetically modified products. Marking system. "In the United States, food labeling or not labeling 'transgene' is voluntarily decided by the food company, but the labeling must be true and cannot be misleading to consumers." The EU implements the quantitative labeling system, which states that when the transgene content of a certain ingredient in a food reaches 0.9% of the ingredient, it must be identified, and the value below this threshold may not be identified. The rumors of genetically modified foods, how much is true? - Potato peeling will become black, some varieties of fruits and vegetables are naturally resistant to storage, imported GM soybeans are not suitable for tofu About genetically modified foods, there are many legends, such as "The EU, Japan do not eat genetically modified foods," "Potato peeling and cutting After the silk is not black, all are genetically modified." "A large number of genetically modified soybeans are imported from China, and tofu and soymilk are all genetically modified," etc. Are these rumors true? Experts answered this question one by one. - "The EU and Japan do not eat genetically modified foods" The truth is: In 1998, the European Union approved the planting and marketing of genetically modified corn in Europe. There are 23 kinds of genetically modified maize, 3 kinds of rape, 1 potato, 3 soybeans and 1 sugar beet. Except for a very small number of feed or industrial uses, the vast majority are used for food. In 2010, a total of 10 GM crops were licensed (EU website); in 2012, five countries including Spain, Portugal, the Czech Republic, Slovakia, and Romania approved the cultivation of transgenic crops (ISAAA). Japan has been the world's largest corn importer and the third largest importer of soybeans for many years. In 2010, Japan imported 14.343 million tons of US corn and 2.347 million tons of US soybeans, most of which are genetically modified varieties. ——"Our potatoes are not black after peeling and shredding, they are genetically modified." The truth is: China has not planted genetically modified potatoes, and there are no countries in the world that have approved the commercial cultivation of potatoes that are resistant to the polyphenol oxidase gene. Whether the potato is blackened or browned after peeling or peeling has a lot to do with its variety and environmental conditions. The speed and degree of darkening mainly depends on the content of phenols, the activity of polyphenol oxidase, and whether it has been cryopreserved. ——"A large number of GM soybeans are imported from China, and tofu and soymilk are all genetically modified." The truth is: Imported genetically modified soybeans have a high fat content and a low protein content. They are suitable for oil extraction and are not suitable for tofu. Most commercially available soy products are domestically produced non-genetically modified soybeans, so there is no need to worry. - "Fruits and vegetables are not easy to be bad genetically modified products" The truth is: There is a large gap in storage between varieties, and some fruit and vegetable varieties are naturally resistant to storage. For example, Guoguang apple skin is thick and can be stored for two or three months without being put in a cold storage. The thick skin and thick wax layer are also relatively Not susceptible to mold attack. In addition, fruits and vegetables have their own preservation conditions, as long as the condition of storage, you can save for a long time, for example, complete watermelon can be stored for more than two weeks, complete onions, carrots in the home for a week without problems. - "Organic food does not contain genetically modified" The truth is: Organic foods are required to strictly follow the organic production regulations, do not use any chemical synthetic pesticides, fertilizers, chemical preservatives and other synthetic substances, and do not use genetic engineering organisms and their products. In other words, organic foods that are certified by formal agencies do not contain genetically modified ingredients. However, the output of organic food is not high and the price is high, so it is unlikely to be widely used. Is it possible to completely avoid genetic modification in life? ——Ensuring food diversity and balanced nutrition and having a healthy lifestyle are the key to maintaining health Can we avoid genetically modified foods in our daily lives? Huang Kunlun said that whether to choose genetically modified foods is the freedom of the public. China's stipulated that all raw materials that have been imported or that have been approved for planting in China are genetically modified foods and directly processed foods. For genetically modified foods, the safety is derived from safety evaluations. That is, through the safety evaluation, the genetically modified product that has obtained the safety certificate is safe and can be eaten with confidence. Some people have expressed doubts: "I'm cooking peanut oil at home, but I'm not going out to eat or I might have eaten fried soybeans?" "Consumers don't have to worry too much about it. The genetically modified components of genetically modified soybeans are insect-resistant proteins and nucleic acids, but the main component of soybean oil is fat, not protein, and almost no product of the so-called 'foreign genes' can be detected. The foods processed from soybean oil have minimal genetically modified ingredients. In Europe, genetically modified components below 0.9% do not need to be labeled, and they are not considered to be genetically modified foods,†said Huang Kunlun. To achieve diet nutrition and safety, Huang Kunlun suggested that the key is to ensure food diversity and achieve a balanced diet. “Nutritional balance is the basic guarantee for the normal body. Eat more fruits, vegetables and coarse grains in the daily diet, appropriate amount of meat and milk, balanced diet, can not choose a certain kind of food for a long time, or believe that any single food will have magical effects. †Xu Haibin, a researcher at the National Food Safety Risk Assessment Center, said that food safety is relative and there is no absolute safety food. For example, for most people, nutritious eggs and milk are the culprits for allergies. The UN Food and Agriculture Organization has listed milk, eggs, fish, crustaceans (shrimp, crab, lobster), peanuts, soybeans, stone fruits (apricots, chestnuts, cashews, etc.) and wheat as a common allergy food. Fan Zhihong, an associate professor at the Food College of China Agricultural University, said that for the majority of consumers who care about health, staying away from genetically modified agricultural products is not the key to health. Eating only non-genetically modified foods does not mean that the health and quality of your diet can be effectively improved. It is hoped that the public will pay more attention to the nutritional balance of the diet, not just whether it is a genetically modified food. For instance, potato chips are not good for health. Whether it is made from genetically modified potatoes or non-genetically modified potatoes, it is equally unhealthy. "If we often eat fried and baked foods, sweet treats and sweet drinks, even if they are all non-genetically modified, they will not always be healthy." “Healthy lifestyle is the most important.†Fan Zhihong said: “It is the most harm to your health! Whether there are genetically modified ingredients or whether they are imported or domestically produced is really not a key issue for health promotion."
