1. Whether it is genetically modified or not: GM maize, which is genetically engineered through modern molecular biology techniques to specific strains of maize, mainly improves resistance to pests and herbicide tolerance; whereas regular maize does not use GMO techniques.2. Whether it contains GM ingredients: In China, regular maize does not contain any GM ingredient as compared to GM maize. 3, the controversy is different: genetically modified food is mainly controversial on health, environmental, ethical and national security issues, while conventional corn is controversial due to external threats such as pests and diseases.

Difference between GMO corn and non-GMO corn

Corn, also known as bracts, bracts stick, corn, pearl rice, etc., is an annual herbaceous plant of the family Gramineae, native to Central and South America. It is an important food crop in the world, widely distributed in the United States, China, Brazil and other countries. Compared with traditional grain crops such as rice and wheat, corn has strong drought tolerance, cold tolerance, barrenness tolerance and excellent environmental adaptability. With its high nutritional value, corn is an excellent food crop.

And genetically modified corn is a genetically modified crop. Transgenic technology is the use of modern biotechnology, the desired target trait genes, after artificial cloning, through the transgenic operation to the recipient organisms, so as to achieve the improvement of the recipient organisms of the original traits or to give its new excellent traits. As a major achievement in the industrialization of biotechnology, transgenic maize has been commonly used around the world.

In the European Union, as long as the total amount of genetically modified ingredients in a food product does not exceed 0.9%, the food product does not need to be labeled as genetically modified. Therefore, the difference between GM maize and conventional maize is the total amount of GM ingredients contained. In our country, as long as the detection of genetically modified ingredients in corn, the food must be labeled as genetically modified corn, and does not contain genetically modified ingredients is conventional corn.
