Onions have a pungent odor, but this is not what causes our eyes to tear whenever we slice these bulbs. It is the release of syn-propanethial-S-oxide, a chemical irritant that stimulates our tear glands. When we cut an onion, an enzyme called lachrymatory-factor synthase is released into the air. This enzyme then couples with the enzyme present in the onion to produce an unstable sulfenic acid that rearranges itself to another gaseous substance, syn-propanethial-S-oxide. This gas gets into our eyes, producing sulfuric acid, and then the tears start flowing.
There are ways in getting around this problem.
- you can wear googles.
- you can chill the onion in the refrigerator before chooping it.
- you can try running tap water over the bulbs as you slice or cut the onion under water.
I just buy the frozen chopped onions!!
ReplyDeleteMuch easier!!
I slice onions under a running water. LOL!
ReplyDeleteI slice onions when I'm standing! that works effectively. siguro matangkad kasi ako! lol

Hi,
ReplyDeleteVisited your blog. Very interesting info!
Onions make you tear. But old onions are worse. They make you cry buckets! So best thing is chop them real fast and get it over and done with! :P
I've never tried wearing googles--wouldn't that be a sight! :-)

ReplyDeletechilling the onion before slicing it is really effective... that's what i do :)
ReplyDeleteyeah, nice to know... hehehe!
ReplyDeletecool post... thanks
ReplyDeletei hate to slice onions but i tip is to open your mouth while slicing that way it minimizes the pain in the eyes cause some will goes into the mouth
ReplyDeleteGreat. I will try the ways you offer next time.
ReplyDeletenice blog and good post
ReplyDeleteThere is a certain way to cut onions which doesn't effect your eyes at all, well it always works for me! The difficulty comes in explaining it.
ReplyDeleteCut the top off the onion but leave the root on the other side. Try cutting the onion in half through the root so the root is on both halves. Then start slicing horizontally towards the root but not all the way to the root so it stays in tact. Then start cutting vertically, again towards the root but so the onion stays in tact.
Finally, cut adjacent to the root to dice the onion. And ta da! All done.
Probably doesn't make any sense but hey ho, it works!! :)
This always happens to me! Thanks for the info.!
ReplyDeleteIt's a kind of our daily secret. :)
ReplyDeletenice post brother.
Now this is right up my street I can so relate to teary eyes in the kitchen
ReplyDeleteMy eyes never get teary when i slice onions tho for some reason, but if my girl starts slicing it she'll look like she's been crying for hours
