Find out here why onions make you cry and how to avoid tears

Kitchens see more profuse tears than movie theaters when showing a dramatic movie or concert halls, even playing the saddest song in the world. Don’t say you’re too strong to cry. This will not prevent bunions. Have you ever wondered why onions make you cry? Check out our article to find the answer, as well as some simple tips to stop crying when cutting this vegetable.

Cut the onion without crying, it’s possible!

It’s actually a matter of biochemistry. Before reaching his kitchen, the onion was on the ground, fed with sunlight and minerals. However, the underground is inhabited by creatures like voles or moles, which love to gnaw on roots, tubers and bulbs. To protect them during their growth, the onion has a very interesting defense mechanism. It absorbs sulfur from the ground so it can release it when its skin is broken. In short, the onion mistakes it for a mole and tries to drive it away. When you try to cut it, it releases enzymes and sulfuric acid. These two compounds combine to produce syn-propanethial-S oxide, which is a volatile gas. Once it reaches the layer of water that covers and protects your eyeballs, this gas turns back into sulfuric acid.

In general, all types of onions contain sulfuric acid. The only difference is in the quantities. That is, white, red and yellow onions cause a stronger chemical reaction than green onions. In addition, agronomists have managed to create a variety of onions that do not irritate the eyes. Unfortunately, it is still not widespread.

Cut under a jet of water

It has been said that volatile sulfuric gas comes in contact with water to turn into sulfuric acid. That’s why if we cut the onion under a jet of cold water, this irritating gas doesn’t have time to touch our eyes before it turns into sulfuric acid, which is not a volatile substance. Why not combine the last two tricks and cut the onion with swimming goggles while diving underwater? So you’re not going to give sulfur gas a chance.

chill the onion

You can put the onion in the fridge or in a bowl of cold water with ice cubes for a few hours. It turns out that this prevents sulfuric gas from being released.

Cut the vacuole at the end

The vacuole or roots in the center of the onion is said to contain the greatest amount of sulfur. Therefore, we advise you to cut the rest of the onion, leaving the roots for the end.
