As of 2013, there is no clear classification of genetically modified foods, and different classifications can be made according to different standards according to practice.
According to whether the genetically modified food contains genetically modified source as the standard, it can be divided into the following three different types:
(1) Genetically modified foods that do not contain genetically modified foods refer to foods that are derived from genetically modified organisms, but the products themselves do not contain any transferred genes.
(2) Genetically modified foods do contain genetically modified ingredients, but their characteristics have been changed during processing, and the transferred active genes no longer exist in genetically modified foods.
(3) Genetically modified foods do contain active genetic components. After people eat such genetically modified organisms or food, the transferred genes and the inherent genes of the organisms will affect the human body.
