Removal of residual pesticides
(1) Peeled organophosphorus, organomercury and pyrethroid pesticides have low solubility in water, but are easily soluble in organic solvents and fats and phenylacetone, waxy solutions. The surface of vegetables is waxy and it is easy to absorb pesticides. Therefore, peeled vegetables should be peeled and eaten. (2) Rinse normal vegetables first with clean water at least 3 to 6 times, then soak in dilute salt water, then rinse again with water. For balsamic vegetables, they can be cut first, soaked in clean water for 1 to 2 hours, and rinsed with clean water to remove residual pesticides. (3) Alkali washing Put a small alkali powder (anhydrous calcium carbonate) or an ice alkali (a crystalline sodium carbonate) in the water, stir well, then add the vegetables, soak for 5 to 6 minutes, and pour the alkaline water, then Rinse with water in the net. It can also be replaced by baking soda, but it takes about 15 minutes to properly extend the soaking time. (4) Washing with detergent The detergent is diluted to 300 times and washed once, then rinsed with clean water for 1 to 2 times. This can remove germs, eggs and pesticides from the vegetables. (5) The best way to remove some of the residual pesticides with hot water is hot, such as green peppers, cauliflower, beans, celery, etc.; it is best to blanch with boiling water before the pot. According to tests, 90% of residual pesticides can be removed. (6) The use of multi-spectral effects in the sun in sunlight will cause some of the pesticides in the vegetables to be decomposed and destroyed, so that the sun-irradiated vegetables have fewer pesticide residues. It has been determined that vegetables and fruits are exposed to sunlight for 5 minutes, and the loss of organic chlorine and organic mercury pesticides is 60%. For vegetables that are easy to store, it is best to place them for a period of time. The oxygen in the air and the color enzymes in the vegetables have a certain decomposition effect on the residual pesticides. Therefore, after buying vegetables, it should be left at room temperature for about 24 hours, so that the average disappearance rate of residual chemical pesticides is 5%. In addition, washing vegetables with rice water can remove some of the pesticides that remain in the vegetables. As most of our country currently use pesticides such as methamidophos, phoxim, dichlorvos, dimethoate and Other organic phosphorus pesticides, these pesticides will lose their toxicity in the event of acidic substances. Soaking in rice water for about 10 minutes, rinse with water, can reduce the pesticide residues in vegetables.
