Ever wondered why Onions make you cry and what steps can be followed to prevent it from happening? Basically, Onions are made up of a tunic of outer leaves(the brown layer), scales(the white juicy edible part), and the basal(the hairy part or the root). When we cut the basal part, it releases an enzyme. This tear-inducing enzyme reacts in the rest of the Onion to release the sulfoxide molecules, and when these molecules combine with water, it converts into sulfenic acid. If you have that water in your eye, then you might have acid in your eyes.
Oops! so, if you have that onion yearning then you can start with below steps to stay tear-free!
Whilst the enzymes are released after cells are broken. Using sharp knife slices through the onion and not crushing them and hence, lesser enzymes get released. Apparently, it will cause lesser irritation in your eyes.
This is quite an efficacious method, but the problem is that it's a bit difficult to execute. Submerge the onions in water and start chopping. All the while you will notice that the onion bits will scatter unless you hold onto them and scooping them up and finally draining all the water out. It can all just not worth doing until you execute this method in a proper way.
Eventually, this method is said to be the most effective way to reduce tears. It really helps to reduce the amount of the acid enzymes released into the air and has no effect on taste.
Drawback: Your fridge might gain smell.
After soaking the onions in water, the enzyme gets denatured by the water-air boundary. However, this eliminates some flavor and the onion becomes a little more slippery in feel than it was.
Steam from a hot pan or kettle of steaming hot tea will do the trick. The science says that the steam will draw the vapors out from the onions and hence, the acid, scattering them.
If you have a pair of swimmer's Gogs or your laboratory goggles, this one is the best trick ever! No onion air will be getting in your eyes. But if they don't fit well on your face, you are just chopping an onion with weird glasses on, with tears in your eyes all the while.
An acidic solution is a natural source to denature the enzyme. You can put vinegar on the chopping board or soak the onion in salt water. The ionic/acidic solution will denature the enzyme and it will cause no irritation in your eyes while cutting. But, this might change the flavor of the onion.
Whistling while you work can make a significant airflow, especially away from your face, which keeps the onion mizzle from entering into your eyes. You can put on some catchy music tracks that definitely won't want to stop whistling and you can continue experimenting with your chopping skills.
Many people admit that chewing , especially bread while cutting onion helps avoid tears. One should chew slowly and let the bread hang out of a mouth a little. Apparently, your mouth will water, but your eyes won't for sure.
All you need to do is, light a candle and put it near your chopping board. The released gas by the onion is drawn into the flame of a candle. I must say this one is not one of your best bets but your kitchen will definitely have a nice odor.
Regardless of whether you take on different other tricks too, you can definitely try your hand on few of these home remedies for tear-free chopping time!!!
