The crying game
Our recent discussion of chemicals led James R. Madden
to offer this explanation about onions and tears:
to offer this explanation about onions and tears:
“Onions produce precursor chemicals containing sulfur.
When the onion is damaged, i.e., sliced, the cells are
disrupted and a number of reactions ensue, one of which
produces propanethial S-oxide, C3H6SO, a lachrymator,
a substance that irritates the eyes and causes tears to flow.

“However, a Vidalia onion is a sweet onion of certain
varieties, grown in a production area defined by Georgia
law and by the U.S. Code of Federal Regulations. They
are named ‘Vidalia’ due to where they are grown rather
than being a specific variety. They are unusually sweet
because the soil in which they are grown is relatively
low in sulfur. This results in onions holding much less
of the aforementioned precursor chemicals than usual.”
