Corn is not a genetically modified food;

The so-called genetically modified food is to transfer one or several exogenous genes into a specific organism through genetic engineering technology and make it It effectively expresses the corresponding product (polypeptide or protein). This process is called transgene. Foods produced using genetically modified organisms as raw materials are genetically modified foods.

According to the different sources of genetically modified foods, they can be divided into plant-based genetically modified foods, animal-based genetically modified foods and microbial genetically modified foods.

From the birth of the world's earliest genetically modified crop (tobacco) in 1983, to the delayed ripening and preservation of genetically modified tomatoes developed by Monsanto's genetically modified food company in the United States and approved for marketing in the United States in 1994, the research and development of genetically modified foods has developed rapidly, and products The variety and output have also doubled. As an emerging biotechnology method, genetically modified foods are immature and uncertain, making the safety of genetically modified foods a focus of attention.
