Why you cry while cutting an onion?

If you are a human then surely you cry every time while cutting an onion and your eyes get irritated but why??

Crying while cutting an onion

Reason: Why you cry while cutting an onion

Onion has cells that release a compound called sulfenic acid. This acid gets to mix with the enzymes of onion and releases another gas called propanethiol S-oxide. This gas gets mixed with the water present in your eyes and produces sulphuric acid. This sulphuric acid irritates your eyes and makes you cry.

Is it harmful to eyes?

No, it's very common

How can you stop tears while cutting an onion

  • Dip the onion in water for 5-10 minutes before you start cutting it.
  • Cut the onion nearby the running water because water will absorb the gas but I suggest don't do this because it will waste the water.
  • Put the onion in the freezer for 10-15 minutes before you start cutting it.
  • You can also wear goggles that cover your eyes fully and do not let gas come in your eyes. I will suggest wearing swimming goggles, you may look funny and people will make fun of you but you can cut onions without crying.
Happy onion cuttings:-):-)
