Life question: why is the armpit cumin?

It's sour. I can't believe it! (please do not read while eating, especially when eating kebabs.)

it is autumn, but it is estimated that many children's shoes still remember the strong "human flavor" on the crowded buses and subways in summer. And in this, the smell of the armpit is very impressive.

the saying "armpits smell like cumin" was first heard by Guo Degang. After listening to it, Po thought it was appropriate! Later, on Weibo, Sun Jie also drew a heavy flavor strip for "armpit cumin" (the link was put on "read the original text". Please help yourself), and everyone was disgusted and vomited and agreed one after another...

then why does the armpit smell like cumin? what does it have to do with cumin? As for the smell, we have to talk about it in terms of chemical composition.

in the human armpit, there are three main odor molecules: 3-methyl-2-hexenoic acid, 3-hydroxy-3-methyl hexanoic acid, and 3-methyl-3-thioalkyl hexanol (chemical nomenclature has been forgotten, so please follow the structural formula. ). Among them, 3-hydroxy-3-methyl hexanoic acid does smell like cumin. The other two are said to be like a goat and the other like an onion.


Human sweat itself is not that tasty, but if you don't take a bath frequently, the bacteria on the body surface will be impolite, and their metabolism will slowly produce all kinds of intoxicating products. So the solution to the smell of cumin in the armpit is very simple. Take more baths when you sweat. Of course, if you are sweating too much, you can ask your doctor for help.

although the above information is enough to destroy cumin and roast the kidney, it is important to say that 3-methyl-2-hexenoic acid is only a little like cumin. The odor molecule in cumin is cumin aldehyde (cumin, Cuminaldehyde). They are completely different things! You can continue to eat kebabs!

this is cumin aldehyde. The chemical structure is different, but the smell is incredibly similar.
