1. Pollution-free food
refers to food with clean ecological environment, which is produced according to specific technical operation procedures, and the content of harmful substances is controlled within the prescribed standards, which is examined and approved by authorized departments, and the use of pollution-free marks is allowed. Pollution-free food pays attention to the safety and quality of products, and its standard requirements are not very high, and there are not many contents involved, which are suitable for the current level of agricultural production development in China and the needs of domestic consumers. For most producers, it is not difficult to meet this requirement. Contemporary agricultural production needs to develop from ordinary agricultural products to pollution-free agricultural products, and then to green food or organic food. Green food bridges between pollution-free food and organic food. Pollution-free food is the primary stage of green food development, and organic food is a higher quality green food.
2. Green food
The concept of green food is put forward by our country, which refers to the pollution-free safe, high-quality and nutritious food that follows the principle of sustainable development, is produced according to a specific mode of production, and is certified by a specialized agency and allowed to use the green food mark. Because things related to environmental protection are usually crowned as "green" in the world, in order to highlight that these foods come from a good ecological environment, they are named green food.
pollution-free, safe, high-quality and nutritious are the characteristics of green food. Pollution-free means that in the process of green food production and processing, through strict monitoring and control, the pollution of pesticide residues, radioactive substances, heavy metals and harmful bacteria to all aspects of food production is prevented to ensure the cleanliness of green food products.
in order to meet the needs of domestic consumers and the competition between China's agricultural production development level and the international market, since 1996, green food has been divided into AA and A grades in the application and approval process.
A-grade green food refers to the products that are allowed to use limited chemical synthetic substances in the production process, are produced and processed according to specific operating procedures, and the product quality and packaging meet specific standards after testing and inspection, and are approved by specialized agencies to use the A-grade green food mark.
AA-grade green food refers to the products with AA-grade green food mark, which are produced and processed according to specific operating procedures without using any harmful chemical synthetic substances in the production process, and whose product quality and packaging meet specific standards after testing and inspection. AA-level green food standards have reached or even exceeded the basic requirements of organic food of the international organic agriculture movement alliance.
3. Organic Food
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. The International Federation of Organic Agriculture Movements (IFOAM) defines organic food as all foods and agricultural products that are produced according to organic food planting standards and production and processing technical specifications, and have been certified and issued certificates by organic food certification organizations. The definition of organic food in the certification standard of the Organic Food Development Center (OFDC) of the State Environmental Protection Agency is: agricultural products and their processed products that come from the organic agricultural production system, are produced and processed according to the organic certification standard, and are certified by an independent organic food certification body. Including grain, vegetables, fruits, dairy products, livestock products, honey, aquatic products, spices and so on.
The most significant difference between organic food and pollution-free food and green food is that the former absolutely prohibits the use of synthetic substances such as pesticides, fertilizers, herbicides, synthetic pigments and hormones in its production and processing, while the latter allows the limited use of these substances. Therefore, the production of organic food is much more difficult than other foods, and it is necessary to establish a brand-new production system and adopt corresponding alternative technologies.
4. Green pollution-free food
Green pollution-free food is a generic term for a kind of pollution-free and safe food that comes from a clean ecological environment, the production mode is related to environmental protection, the harmful substance content is controlled within a certain range, and it has been certified by a specialized agency. It includes pollution-free food, green food and organic food.
We should pay attention to the following issues in the understanding of green pollution-free food:
(1) Green pollution-free food is not necessarily green, and green food is not necessarily green pollution-free food. Green refers to things related to environmental protection, such as Greenpeace, green barriers and green refrigerators.
(2) Pollution-free is a relative concept, and whether the substances contained in food are harmful or not is also relative. It is necessary to have a concept of quantity. Only when a certain substance reaches a certain amount will it be harmful and cause pollution to food. As long as the content of harmful substances is controlled within the scope stipulated by the standard, it may become a green pollution-free food.
(3) It is not only in remote and pollution-free areas that green pollution-free food can be produced. In the suburbs of big cities, green pollution-free food can be produced as long as the pollutants in the environment do not exceed the scope stipulated by the standards. From the analysis of the role of reducing agricultural chemical pollution, it has more important environmental protection significance in developed areas.
(4) Foods produced in closed, backward and remote mountainous areas and areas not polluted by human activities are not necessarily green and pollution-free foods. Sometimes the atmosphere, soil or rivers in these areas contain natural harmful substances.
(5) Wild and natural foods, such as wild vegetables and wild fruits, can't be regarded as real green pollution-free foods. Sometimes these wild foods or their living environment contain excessive pollutants, and whether they are green pollution-free foods or not must be certified by special institutions.
second, what's the difference between organic food, pollution-free food and green food
Besides organic food, there are pollution-free food and green food which are currently being promoted in China's market. What's the difference between these products?
According to experts, pollution-free food is produced according to the corresponding production technical standards, conforms to the general hygiene standards and is recognized by relevant departments as safe food. Strictly speaking, pollution-free is a basic requirement of food, and ordinary food should meet this requirement.
green food is a certified food promoted by the agricultural sector in China, which is divided into two types: A-grade and AA-grade. Among them, limited use of chemically synthesized means of production is allowed in the production of Grade A green food, while Grade AA green food is strictly required not to use chemically synthesized fertilizers, pesticides, veterinary drugs, feed additives, food additives and other substances harmful to the environment and health in the production process. In essence, green food is a transitional product from ordinary food to organic food.
organic food refers to agricultural and sideline products and their processed products that are produced and processed in an organic way, meet relevant standards and have been certified by specialized certification bodies, including grain, vegetables, dairy products, livestock products, honey, aquatic products and seasonings. There are three main differences between organic food and other foods:
First, it is absolutely forbidden to use synthetic substances such as pesticides, fertilizers and hormones in the production and processing of organic food, and genetic engineering technology is not allowed; Other foods allow limited use of these substances, and genetic engineering technology is not prohibited. For example, the use of genetic engineering technology and radiation technology in green food is not stipulated.
second, organic food has strict regulations on land production transformation. Considering that some substances will remain in the environment for a long time, it takes two to three years for the land to produce other foods to produce organic foods, but there is no requirement for the production of green foods and pollution-free foods.
Third, the quantity of organic food is strictly controlled, which requires a fixed plot of land and a fixed output. There is no such strict requirement for the production of other foods.
In short, it is more difficult to produce organic food than other foods. It is necessary to establish a brand-new production system and monitoring system, and adopt corresponding alternative technologies such as pest control, soil fertility conservation, seed cultivation, product processing and storage.
