Many people like to eat onions in their daily life, but many people will find a problem when eating onions, that is, their eyes tear more. This is because one element in onions will stimulate our facial nerves after being released, causing many people to have such a reaction. Therefore, it is necessary to use water to avoid tears when cutting onions.

When cutting onions, due to the volatile substances in onions, it often causes tears in the person cutting the vegetables. The prevention method is:

1. Before cutting onions, dip the cutting knife in cold water for a while, and you won’t tear when cutting because of the stimulation of volatile substances.

2. After cutting the onion in half, soak it in cold water first and then cut it, and it won’t tear.

3. Heat it in the microwave for a while, the skin comes off easily, and it doesn’t tear when cutting.

4. Soak the onion in hot water for 3 minutes before cutting.

5. Cut onions while wearing swimming goggles.

6. Cut onions while holding your breath. Because the smell of onions is transmitted to the brain nerve through the nose, causing tears in the eyes.

7. When cutting onions, you can light a candle next to the cutting board to reduce the刺激性 smell of onions. The effect is good! (Haha, it’s fun. It’s quite unique!!!)

8. If you are already ‘weeping like a river’, you can stick your head into the freezer of the refrigerator for a moment (as long as you feel a little cool on your face), and your eyes will not tear! Try it out!!!
