When you
cut an onion, you break cells, releasing their contents called Amino acid
sulfoxides form sulfenic acids. Enzymes that were kept separate now are free to
mix with the sulfenic acids to produce propanethiol S-oxide, a volatile sulfur
compound that wafts upward toward your eyes. This gas reacts with the water in
your tears to form sulfuric acid. The sulfuric acid burn and stimulating your
eyes to release more tears to wash away the irritant.
Cooking the
onion will inactivates the enzymes, the smell of cooked onions may be strong
but doesn't burn your eyes. Aside wearing safety goggles or running a fan, you
can keep from crying by refrigerating onions before cutting it. Onios enzymes
will have slows reactions and changes the chemistry inside the onion. Another
option is cutting the onion under water. The sulfur-containing compounds also
leave a characteristic odor on your fingers. You may be able to remove or
