I hate that my guacamole just doesn’t taste nearly as delicious when I don’t add onions, I just hate chopping them.
So why DO onions make you cry. Here’s a scientific explanation word for word from a science-y government website.
“Onions produce the chemical irritant known as syn-propanethial-S-oxide. It stimulates the eyes' lachrymal glands so they release tears. Scientists used to blame the enzyme allinase for the instability of substances in a cut onion. Recent studies from Japan, however, proved that lachrymatory-factor synthase, (a previously undiscovered enzyme) is the culprit (Imani et al, 2002).
The process goes as follows:
- Lachrymatory-factor synthase is released into the air when we cut an onion.
- The synthase enzyme converts the sulfoxides (amino acids) of the onion into sulfenic acid.
- The unstable sulfenic acid rearranges itself into syn-ropanethial-S-oxide.
- Syn-propanethial-S-oxide gets into the air and comes in contact with our eyes. The lachrymal glands become irritated and produces the tears!”
Thank you onion mystery facts
Okay so lets simplify in commoner everyday English, onions have a gas in them that is suppose to protect them from predators, when you kill the onion aka ‘chopping’ it, its like omg someone is trying to murder me and it protects itself by releasing a gas to thwart its enemy aka ‘me’… I always win though, but not without a fight, okay, okay so maybe that’s NOT the literal non-science-y translation, that’s what it feels like sometimes though.
So there you have it, from grapples to murder. Onions, our kitchen foe.
