housewives’ spirit of loving the family is obvious to all. As the guardian of the family, they use love to isolate all unsafe factors, so that the family can feel full of love and happiness! Want to lay a healthy foundation for your family. Food cleanliness and hygiene naturally become the most important thing. As a housewife, do you know how to filter the residual pesticides on vegetables? In fact, this is a unique skill!
unique skill 1. Peel
the vegetable surface has wax, which is easy to absorb pesticides. Therefore, vegetables that can be peeled should be peeled before eating.
stunt 2. Wash
generally, wash vegetables with clean water at least 3-6 times, and then soak them in light salt water and wash them again. For pericardial vegetables, cut them first, soak them in clean water for 1-2 hours, and then rinse them with clean water to remove residual pesticides.
trick 3. Alkali washing
first put a small spoonful of alkali powder (anhydrous sodium carbonate) or ice alkali (crystalline sodium carbonate) in the water and mix well before putting vegetables. Soak for 5-6 minutes, pour out the alkaline water, and then rinse it with clean water. If there is no alkali powder or ice alkali, baking soda can be used instead, but the soaking time can be extended appropriately, which generally takes about 15 minutes.
trick 4. Wash with detergent
dilute with detergent 300 times, wash once, and then rinse with clean water 1-2 times, so as to remove bacteria, insect eggs and residual pesticides on vegetables.
trick 5. Scald
with boiling water. The best way to remove some residual pesticides is scalding, such as green pepper, cauliflower, beans and celery. It is best to scald with boiling water before frying or burning. According to the test, more than 90% of residual pesticides can be removed.
unique skill 6. Sunshine
using the multispectral effect of sunlight, some residual pesticides in vegetables will be decomposed and destroyed. In this way, the vegetables dried by sunlight have less pesticide residues. According to the determination, when fresh vegetables and fruits are exposed to the sun for 5 minutes, the residue loss of organochlorine and organic mercury pesticides is up to 60%.
for vegetables that are convenient for storage, it is best to place them for a period of time. Oxygen in the air and chromozymes in vegetables have a certain decomposition effect on residual pesticides. The average disappearance rate of residual chemical pesticides was 5% when vegetables were placed at room temperature for about 24 hours.
in addition, washing vegetables with rice washing water can remove some pesticides left on vegetables. At present, methamidophos, phoxim, dichlorvos, dimethoate and other organophosphorus pesticides are mostly used to kill insects in China. These pesticides will lose their toxicity in case of acid substances. Soaking in rice washing water for about 10 minutes and washing it with clean water can reduce the pesticide residues in vegetables.
