Significance of pollution-free food

2 1 century will be the century of green products. With the development of economy and society, the continuous improvement of people's living standards and the rapid development of international environmental protection technology, people put forward higher requirements for the quality of agricultural products, especially edible agricultural products. Safe and pollution-free high-quality agricultural products have become the first food needed by the market and consumers, and safety has become an important index requirement of agricultural product quality standards. Improving the quality of agricultural products has become an urgent desire and requirement of consumers. Only in clear water, even on cloudy days, the water temperature is controlled at a low temperature. Thirdly, in pest control, aerosol and dust agent can be used instead of spray to reduce the humidity in the shed. Fourth, often wipe the greenhouse film to maintain good light transmittance of the greenhouse film. Increase light. Increase the temperature and decrease the relative humidity. Fifth, in the aspect of frost damage prevention, measures such as thickening the wall, covering with double-layer film, using film pressing line to reduce holes, adding greenhouses, digging cold trenches and so on are taken. Taking measures to improve the insulation effect of greenhouse can reduce the relative humidity and set different environmental standards for the same variety.

The main difference between pollution-free food production technical standards and green food production technical standards is that pollution-free food production technical standards are mainly pollution-free food production technical regulations standards, and only some products have guidelines for the use of production materials, and their production technical regulations standards are only used as reference for product certification. Due to the universality of pollution-free food, the production technical standards of pollution-free food cannot be adhered to. The technical standard of green food production includes two parts: the guide to the use of raw materials for green food production and the technical regulations for green food production, which is the core standard of green food. The certification and management of green food focus on putting the technical standards of green food production in place. Only when the technical standards of green food production are in place can the quality of green food be truly guaranteed.

The main difference between the standards of pollution-free food and green food is that the hygiene index is quite different, and the hygiene index of green food is obviously stricter than that of pollution-free food. Take cucumber as an example: the hygienic index of pollution-free food cucumber is 1 1, and that of green food cucumber is18; The hygienic requirement of pollution-free food cucumber is dichlorvos ≤0.2 mg/kg, and that of green food cucumber is dichlorvos ≤0. 1 mg/kg. In addition, green food vegetables also stipulate the specific requirements of sensory and nutritional indicators, while pollution-free vegetables do not. Green food has a general packaging guide, but pollution-free food does not. According to the provisions of national laws and regulations and the impact of food on human health and the environment, the product standards and environmental standards of pollution-free food are mandatory standards, and the production technical specifications are recommended standards.
