The main reason for the large amount of pesticide residues in vegetables is that some vegetable farmers do not pay attention to agricultural comprehensive prevention and control measures. Ecological control and physical control methods are used less frequently; once the disease occurs, there is a lack of knowledge about the safe use of pesticides, and the use of pesticides is arbitrarily violated. The use of highly toxic, high-residue banned pesticides was not carried out on the market until strict safety intervals were implemented. In recent years, incidents of poisoning due to excessive pesticide residues often occur. As consumers, what methods can be used to eliminate or reduce residual pesticides in vegetables? First, peeled Organic phosphorus, organomercury and pyrethroid pesticides have low solubility in water, but are easily soluble in organic solvents or waxy liquids. The surface of vegetables has waxiness and it is easy to absorb pesticides. Therefore, peeled vegetables such as cucumber, gourd, squash, etc. should be peeled before eating. Second, water washing and immersion washing method After the general vegetables are bought, they must be rinsed with water for 3 to 4 times, then immersed in clean water for 1-2 hours before rinsing. Washing water is the basic method to eliminate dirt on vegetables and fruits and remove residual pesticides, especially for leafy vegetables such as chives (water spinach), spinach, green vegetables, lettuce, and Chinese cabbage. For balsamic vegetables, remove 1-2 leaves from the surface, rinse with fresh water for 2-3 times, then soak in clean water for 1-2 hours before cleaning to remove residual pesticides. (Water flushing and immersion washing must not be reversed and sequenced, otherwise pesticides remaining on the surface of the blade will infiltrate into the vegetable cell tissue during the soaking process) Third, alkaline water immersion method Organophosphorus pesticides decompose rapidly under alkaline conditions, so this method is an effective measure to remove pesticide contamination and can be used for all kinds of vegetables and fruits. The method is to first put a small amount of baking soda in water, stir well and then add vegetables. After soaking for 15 minutes, drain the alkaline water and rinse with clean water. Fourth, heating method As the temperature rises, carbamate insecticides break down faster, so some of the vegetables and fruits that are difficult to handle can be removed by heating, such as leeks (convolvulus), vegetables, celery, cauliflower, beans. Wait. The method is to wash the surface dirt with clean water and put it into boiling water for 2-3 minutes. According to the test, it can remove more than 80% of the residual pesticide. In addition, you can use rice water to soak the vegetables for about 10 minutes, and then rinse with water. The above methods can also be used in combination, comprehensive treatment, the effect will be better. Demetdent Dental milling machines were built for reliable, precise and error-free milling.
