Refrigerated storage of vegetables can reduce pesticide residues

For the pesticides, some citizens think that washing with detergent can be eliminated, while others think that it is a good thing to soak vegetables containing pesticide residues in the water for a while. Experts caution that neither approach is desirable. First of all, the detergent itself is a chemical substance. Washing vegetables can not only completely eliminate the pesticide residues, but may cause secondary pollution. Secondly, if the vegetables have agricultural residues and are soaked in non-flowing water, the vegetables are actually soaked in the water with pesticide residues, which can't play much role.
Experts suggest that the fresh vegetables that have just been purchased, especially the fruits and vegetables, should be stored in the refrigerator for 3 days - 5 days before eating, so that the pesticide residue will be greatly reduced. Because harmful substances will gradually decompose and weaken at a low temperature for a certain period of time. In addition, the currently recognized method for removing pesticide residues is to “wash one, two, three, and four.” After washing the vegetables, put them in the water for a while, then burn them in the pot for a few minutes, and finally pour off the water of the hot vegetables. However, this will also lose a lot of water-soluble vitamins and inorganic salts.
