We cut tears easily when we cut onions. In fact, there are many ways to cut onions in your life. So how do onions cut into tears?
1. put onions in the frozen layer, frozen cut 15 minutes. Freezing does not damage onion flavor, but it also reduces the production of irritants.
2. cut onions in a ventilated place, such as carrying an electric fan, blowing it directly, or turning on the hood to minimize the exposure to the onion. Onions can also be cut in airtight containers.
3. cut the onions before they are heated in the oven and destroy the enzymes.
4. wear contact lenses to block contact between the cornea and the SPSO acid. Some people will wear goggles, but will affect the line of sight, to be careful when cutting onions.
5. cut the candle before cutting the onion, so that when you cut the onion, the volatile substance will be sucked into the flame there, rather than irritating to the eyes and nose mucosa.
