The green food logo also reminds people to protect the environment and prevent pollution, and create a new harmony in nature by improving the relationship between people and the environment. It is registered in nine major food categories, mainly food, and has been extended to green food-related products such as fertilizers. As a product quality certification trademark, the green food mark's exclusive trademark rights are protected by the Trademark Law of the People's Republic of China. The use of the logo means that the food has been certified by a specialized agency and is allowed to be used by enterprises in accordance with the law. First, let’s introduce what green food is: Green food does not refer to food that is green in color, but is China’s general term for pollution-free, safe, high-quality, nutritious food.
