When cooking, wait until the oil starts to smoke before putting the food in the pan. In the past, vegetable oil was used for cooking, and the oil needed to be heated very hot to make the food fragrant. Nowadays, cooking oil is basically refined oil. If the oil temperature is too high, it will not only destroy the nutrition of the food, but also may produce harmful substances. So it is best to remind parents to put the food in the pan when there is no smoke, no sound, and you can feel the heat. Turn off the range hood as soon as you finish cooking. The fumes will not dissipate immediately after cooking. If the range hood is turned off too early, the remaining fume particles cannot be discharged. Therefore, after cooking, leave the range hood on for about 3 minutes. Frying with leftover oil. Oil will oxidize and become rancid under high temperature, which will not only reduce its own nutritional value, but also destroy the B vitamins in other foods. In addition, oil may produce some harmful substances during repeated frying. If you are reluctant to throw away leftover oil, it is best to filter the residue, seal and refrigerate it, use it up as soon as possible, and it is best to use it only once. Thaw frozen food in advance. The two most common methods are air thawing and cold water thawing. Both methods will cause the loss of nutrients and there is also the risk of breeding microorganisms. The correct way is to thaw in the refrigerator. Adding water to dishwashing liquid. Tap water is not sterile. Adding it to dishwashing liquid may affect the antiseptic effect. The dishwashing liquid that is supposed to clean things may become a culture dish for bacteria. Whether it is dishwashing liquid or shampoo, you can only use it once by adding water when you really can't squeeze it out. Repeatedly adding water may accelerate the deterioration of the product.
