We can put a basin of water next to the onions when cutting them, or soak the onions directly in the water. We can also put the onions in the refrigerator in advance and freeze them before cutting.

1. Put a bowl of water next to it

First of all, when we are cutting onions, we can put a large bowl of water next to the chopping board. This will reduce the impact of the onions on the chopping board. Eye irritation, the principle is that the irritating gas released by the onion will be absorbed by the water in the bowl next to it.

2. Soak the onion in water

We can cut the onion first, then soak it in cold water for 2 to 3 minutes, and then take it out and cut it. , it will not cause irritation to the eyes. This is actually the same as the previous method, which is to dissolve the alliinase in onions in water so that it cannot volatilize and cause irritation to our eyes.

3. Put the onion in the refrigerator

We can wrap the onion in a plastic bag, put it in the freezer of the refrigerator to freeze, and take it out after a period of time. , and then cut again, no irritating gas will be volatilized, and it will not irritate the eyes to shed tears, because in a low temperature environment, alliinase will not solidify and freeze, and cannot volatilize or slow down its volatilization, thereby reducing It is irritating to our eyes.

Since the alliinase in onions is volatile and can cause irritation to our eyes and noses, as long as we control the volatilization of the chemicals in onions, we can control the irritation to our eyes. Through chemical methods, it brings convenience to our lives.
