What about genetically modified soybeans?

Genetically modified soybeans can resist the herbicide glyphosate (poison drop mixture). Glyphosate will kill ordinary soybean plants along with weeds, but the application of glyphosate herbicides in genetically modified soybean fields will not affect soybean yield. but the toxicity and safety risks of genetically modified soybeans have always been controversial, so let's take a look at what's going on with GM soybeans.

What about genetically modified soybeans?

Genetically modified soybeans are developed to cooperate with the use of glyphosate herbicides, which are selective and non-selective, while glyphosate is a non-selective herbicide. Glyphosate-resistant transgenic crops are currently the largest GM crops in the world. Glyphosate kills plants by destroying the EPSPS in their chloroplasts or plastids. Genetically modified plants produce more EPSPS enzymes to resist glyphosate, thus keeping crops from being killed by glyphosate herbicides. With such genetically modified soybeans, farmers do not have to use multiple herbicides as they did in the past, and only glyphosate is needed to kill all kinds of weeds.

Identification methods of genetically modified soybean

1. Shape: the shape of non-GM soybeans is oval and a little flat. The shape of genetically modified soybeans is round and round.

2. Color: the belly button of non-GM soybeans is light brown. The "belly button" of GM soybeans is yellow or yellowish brown.

3. Size: the sizes of non-GM soybeans are not the same. GM soybeans are all about the same size.

4. Soybean milk: the soybean milk produced by non-GM soybeans is milky white. The soy milk produced by genetically modified soybeans is a little yellow.

5. Bean sprouts: soaking soybeans in water for three days, genetically modified soybeans will not sprout, but will only become individual swelling, while non-genetically modified soybeans can basically see the sprouts grow out.

6. Moth moth: genetically modified soybeans have been transferred into insect-resistant and drug-resistant genes, so genetically modified soybeans are usually neat in shape and can hardly see any signs of moth. If it is not genetically modified, it is easy to give birth to insects if it is not properly preserved.

What are the common genetically modified foods?

1. Tomatoes: I believe that many people like to eat tomatoes, and it is precisely because most people around the world like this vegetable that scientists have studied tomatoes more deeply, and it is found that the genes of tomatoes are relatively easy to transfer. therefore, the tomatoes eaten today are also slowly becoming genetically modified, and there is even a tendency to start commercial production.

2. Sweet peppers: approved by the Ministry of Agriculture in 1998, genetically modified colored peppers were allowed to be planted commercially, but genetically modified colored peppers do not seem to have received much welcome from the public in our country, and today they basically do not produce genetically modified colored peppers. However, it does not rule out the possibility that some businesses secretly plant genetically modified colored peppers in violation of government regulations.

3. Corn: transgenic corn is the use of modern molecular biotechnology to introduce genes of very distant and useful plants into maize genetic material that needs to be improved, and to make its offspring reflect the maize with stable genetic traits that people pursue. At present, it has been allowed to be imported to the United States in China.

4. Rapeseed: rapeseed can be used to produce oil, so many people who study agriculture will focus on it. Now genetically modified rapeseed is still controversial in governments all over the world. In the final analysis, it is still worried about toxicity and allergy. Although the cultivation of genetically modified rapeseed has not been promoted in our country, genetically modified rapeseed is imported.

5. Soybeans: when we go to buy cooking oil, we often find that some edible oils will be labeled "genetically modified soybeans". In fact, genetically modified soybeans have begun to enter the Chinese market on a large scale, and they are mainly used for the processing of edible oils. it is unknown whether genetically modified soybeans are being sold on the market.
