Although "genetically modified foods" have entered the Chinese market for many years, the doubts about the safety of genetically modified foods have remained undiminished. Some people have accepted the belief that GM foods are safe and reliable. Some people are reluctant to eat genetically modified products regardless of the relevant agencies. food. Election or not selection is everyone’s autonomy, but how much do you know about GM foods? How many foods are mistakenly thought to be genetically modified and avoided? How many genuine "genetically modified" foods are sneaked out under your eyelids?
Almost all papayas are genetically modified!
It is understood that the five major categories of 17 genetically modified organisms listed in the transgenic labeling catalogue and sold on the market need to be marked in China. Currently, genetically modified foods such as soybean oil, rapeseed oil and blend oils containing genetically modified ingredients on the market have been marked. Consumers only need to carefully check the labels at the time of purchase for identification. It is worth mentioning that 17 categories of 5 categories do not include rice. If rice is commercialized, it may need to be added to the label list.
But is there no genetically modified food or food? Of course not, Prof. Luo Yunbo of the Food College of China Agricultural University told NetEase Health that, for instance, papaya is almost all genetically modified. This is because if papaya is infected with the ring spot virus, it can't be eaten anymore. Without genetic modification, it means We will not be able to eat papaya. Not only at home, but also in other countries and regions of the world, almost all of them are genetically modified papaya. However, papaya is not labeled. Why is this? First of all, the papayas that everyone can eat are almost all genetically modified. Second, the papaya producers are relatively dispersed, they are relatively small, they have one household, one farmer has dozens of trees, and distribution methods are difficult to control, such as farmers. The self-produced and self-selling products in the bazaars are not operability. The labeling is subject to factors such as operability and economic development levels. At present, there is no indication of which country has labeled GM papaya.
Is color egg and color green pepper a genetically modified food?
Many people believe that "colored shell" eggs are genetically modified. Kexin Food and Nutrition Information Exchange Center Dan Guangfeng told NetEase Health. In fact, this has nothing to do with genetic modification, mainly related to chicken breeds. When the hens are of the same species, eating different feeds will also produce eggs of different colors. Different varieties, different feed, egg shell, egg yolk will show different colors.
Eggshells are white, light brown, brown, dark brown, and cyan. Some people prefer red shell eggs. Some people like green shell eggs and think that the nutritional value is higher. In fact, the nutritional value of eggs is high and low, and it is not necessarily related to the color of egg shells, nor is it related to transgenes. Regardless of the color of the eggs produced, the chickens used for consumption, or the laying hens, are not genetically modified. This is not permitted by our laws.
Chickens used for food and laying hens are not genetically modified. Chickens are not genetically modified, and eggs are not even genetically modified.
Color cocoon is also a problem that people are puzzled about. Yan Guangfeng told Netease Health that, generally speaking, the silkworm cocoons made at home for silkworm rearing are different in color, mainly because the varieties of silkworms are not the same. The formation of different varieties is due to genetic mutations, the number of chromosomes is not the same, the genes are not the same, so the cocoon color is not the same. Since color silkworms are popular among people, nowadays, industrialized production can obtain color silkworm cocoons by adding pigments, biotechnology, and breeding (that is, breeding) using colored pigments.
The color green pepper, commonly known as colored pepper, is biologically a hybrid plant and is not a genetically modified food.
Is it a genetically modified potato that is not black?
Others also questioned whether "the potatoes are not black after peeling and shredding, are they genetically modified?" The truth is that China has not planted genetically modified potatoes, and there is no country in the world that has approved the commercial planting of potatoes that are resistant to the polyphenol oxidase gene. In other words, all potatoes in the domestic market are non-transplanted potatoes. On the Internet, the identification of genetically modified and non-transplanted potatoes was misrepresented.
Whether the potato is blackened or browned after peeling or peeling has a lot to do with 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. In addition, no transgenic brown potato varieties have been grown in China.
Misunderstood genetically modified foods
Is "Cherry fruit" a genetically modified tomato? No! It is just a matter of breed, pure natural, and it has nothing to do with genetic modification. In fact, the small tomato is the original state of the tomato, and the big tomato that people eat today is the result of long-term seed selection.
Purple sweet potato is also a food misunderstood. Purple sweet potato contains anthocyanins. These plant pigments also play an important role in human health. Anthocyanin is the reason purple potatoes appear purple, not because of genetic modification.
Black peanuts are not genetically modified foods but are hybrids like hybrid rice. The black peanut is a new peanut variety selected from the sexual hybridization system after irradiation of high-generation materials according to the genetic variation of peanuts. The black color of black peanuts is natural and is determined by the genes that control pigments. The nutritional value of black peanuts is extremely high, so don't miss the good food because of "misunderstanding".
What are the common genetically modified foods?
The common genetically modified foods have been included in the seven categories of the top five categories, but they have been made into different products. For example, genetically modified soybeans contain genetically modified insect-resistant proteins and nucleic acids, but the main component of soybean oil is oil, not protein, and almost no products of the so-called 'foreign genes' are detected. The foods processed by soybean oil that are exposed by consumers are genetically modified to a minimum. This is a state-approved food product that meets the requirements of food safety. However, these soybeans mainly enter the oil mill as processing raw materials for cooking oil and are not used as raw milk. . Currently imported GM soybeans, corn, and rapeseed use are limited to processing raw materials.
Prof. Luo Yunbo said that we also have genetically modified corn that we have developed in China. Now we have also obtained a safety certificate. It is on the road to commercialization that these are actually among the top five categories and they need to be marked when they are sold as commodities. Netease Health NetEase Hu Yuhui
