How to remove pesticide residues from green onions
1. Peeling: There is wax on the surface of vegetables, which is easy to adsorb pesticides. Therefore, vegetables that can be peeled should be peeled before eating.
2. Wash: Wash vegetables with clear water for at least 3-6 times, then soak them in light salt water and wash them again. Cut the wrapped vegetables first, soak them in clear water for 1-2 hours, and then rinse them with clear water to remove residual pesticides.
3. Alkali washing: First, put a spoonful of alkali powder (anhydrous sodium carbonate) or ice alkali (crystalline sodium carbonate) into water and stir evenly, then add vegetables. Soak for 5-6 minutes, pour out alkaline water, and then rinse with clear water. If there is no alkali powder or ice alkali, baking soda can be used instead, but it usually takes about 15 minutes, and the soaking time is appropriately extended.
4. Wash with detergent: dilute 300 times with detergent, wash once, and then rinse with clean water 1-2 times to remove germs, eggs and residual pesticides on vegetables.
5. Boiling water: The best way to remove some residual pesticides is scalding, such as green pepper, cauliflower, beans and celery. It's best to blanch in boiling water first, and then fry or burn it in a pot. According to experiments, more than 90% of the residual pesticides can be removed. 6. Sunlight exposure: By using the multi-spectral effect in sunlight, some residual pesticides in vegetables will be decomposed and destroyed. In this way, there is less pesticide residue in dried vegetables. For vegetables that are convenient to store, it is best to leave them for a while. Oxygen in the air and chromozyme in vegetables have a certain decomposition effect on residual pesticides.
7. Salt washing: Chemical pesticides and fertilizers are often used in vegetable planting. In order to eliminate the pesticide residues in vegetable epidermis, it can achieve good results to wash vegetables with 1%-3% light salt water. In addition, vegetables harvested in autumn often hide various insects in the lines of roots or leaves. Washing vegetables with clear water is easy to remove.
