What is green food? Do you enjoy green food every day? The concept of “green food” was first suggested by the Department of the Ministry of Agriculture in 1990.
Green symbolizes life, health and energy. Nowadays, people demand healthy and fresh food. Having enough food to eat is only a basic requirement, and they need more than this. They want to enjoy unpolluted, safe and nutritious food and eat comfortably. So the government does this through a set of “from the land to the dinner table” quality controls. It requires to change China’s traditional agricultural structures and ensure the food of high quality.
Safe vegetables refers to products without substances harmful to humans. Growing such vegetables requires no strong poisons, thus guaranteeing vegetables fresh and clean. There are strict regulations in place for even applying fertilizer(肥料). The examination of vegetables should reach the state food hygiene(卫生) standard. The following conditions for green food are regulated by the China Green Food Development Center. Firstly, products or raw materials must reach the green ecological environment standard set by the Ministry of Agriculture. Secondly, crop planting, livestock raising, fish breeding and food processing must follow green food operating procedures set by the Ministry. Products must be up to the green food hygiene standard. External packing must be pasted with national standard universal labels, special green food packing decoration and tag regulations.
However, by now, our goal hasn’t been completely realized. When you return home with a full basket, you are still worried about whether what you have bought is green and healthy. Indeed, for the sake of our health, we still have a long way to go.
