If green food, organic food, pollution-free food and food are arranged according to the pyramid, green food is in the middle and organic food is at the top of the pyramid. Organic Food is an internationally recognized term. This term is literally translated from organic food in Britain and France, and it is also called ecological or biological food in other languages. The "organic" mentioned here is not a chemical concept, so organic food is not a variety of food, but a food that has undergone a specific production process, including grain, vegetables, fruits, dairy products, livestock products, honey, fruits, seasonings and so on.

Organic food must meet the following four conditions: (1) Raw materials must come from organic agricultural production systems established or being established by themselves, or wild natural products collected by organic means; (2) The products strictly follow the production, processing, packaging, storage and transportation standards of organic food in the whole production process; (3) In the process of organic food production and circulation, producers have a perfect quality tracking and review system and complete production and sales records; (4) It must be certified by an independent organic food certification body. Generally, organic food bases are located in natural mountainous areas without polluted environment, such as northeast Yunnan and other places, and the procedure of organic certification is very strict compared with green food, which lasts for a long time and has high production cost, so the price of organic food is very high now, which is embarrassing.

The concept of green food was put forward by our country, and its characteristics are pollution-free, safety, high quality and nutrition. Of course, the domestic food is basically green food now, and this certificate is easy to get.
