Method 1: Chew gum and cut onions.
When cutting onions, you can easily solve the problem of tears by chewing gum. Why? Because when cutting onions, the pungent smell will stimulate people's glasses, which will increase the tears secreted by lacrimal glands, and the tears will naturally flow out involuntarily. However, if you chew a piece of chewing gum in your mouth, the upper and lower jaws keep opening and closing. At the moment of opening your mouth, the internal space of your mouth keeps expanding, which will form a negative pressure inside, thus sucking tears into your mouth through the internal channel, so that the glasses will not gush out tears. Isn't it amazing? But it does work.
Method 2: first refrigerate the onions for a while.
Before cutting onions, put them in plastic bags and put them in the freezer of the refrigerator for a few minutes. When the onions are cool but not frozen, take them out in time. Then cut the onions, and the stimulation of the onions will be less. Then why is this? Because of cold, onion slows down the release rate of enzyme, so the pungent smell of onion will be reduced. In addition, this enzyme is mainly concentrated in the root of onion. Cutting this part as late as possible can also effectively slow down and reduce tears.
Method 3: Cut onions with water in your mouth.
This method is very simple, that is, when cutting onions, put a mouthful of water in your mouth, be careful not to swallow it, and then take the time to cut the onions. After cutting, spit out the water in your mouth, so that there will be no tears in the whole process of cutting onions.
