Onions, along with many other plant life within the Allium species (garlic is another famous one), absorb sulfur from the soil.  while onions are chopped, it ends up breaking cells within the onion, which releases sure enzymes.  Those enzymes then react with the sulfur, creating amino acid sulfoxides.  Those, in turn, create the exceptionally volatile syn-propanethial-S-oxide, that is a aggregate of sulfuric acid, sulfur dioxide, and hydrogen sulfide.    When this substance, in a gaseous state, comes in touch with the moisture on your eye, it triggers a burning sensation through the ciliary nerve.

Tears in the eyes are regulated by means of the lachrymal gland, which is located just above your eyelids.  Whilst the mind receives a message that there may be an irritant in the eye, together with the above syn-propanethial-S-oxide, which gives a burning sensation, it then kicks the lachrymal glands into overdrive, looking to flush the irritant out of your eye(s) with tears.

Cooked onions gained’t produce this same impact due to the fact the procedure of cooking the onion inactivates the enzymes had to make the syn-propanethial-S-oxide.  So you can competently chew the cooked onions without getting teary-eyed.

Best methods to prevent Onions From Making Your Eyes Water

•           Refrigerate the onion at least half-hour earlier than cutting.  alternatively, placed the onion in ice-water for a couple of minutes earlier than cutting.  by cooling the onion, you will gradual the enzyme/sulfoxides response rate, minimizing the syn-propanethial-S-oxide production.

•           Flip a fan on, blowing across the onions and faraway from you.

•           Run water over the onions as you narrow them.  The syn-propanethial-S-oxide that purpose the eye inflammation is water soluble, so can really be washed away earlier than having a chance to get within the air.

•           Prepare dinner onions regularly.  studies has shown that the more you chop onions up, the much less the sulfuric compounds will have an effect on your eyes. (Source: todayifoundout)
