Why Does Chopping Garlic Make it Smell So Strong?
Garlic smells strong after you chop it because of a cool chemical reaction.
Inside garlic, there are two separate ingredients, alliin and alliinase, that don't mix when the garlic is whole.
When you chop garlic, you break open tiny compartments, letting the ingredients mix.
This creates allicin, which smells like garlic.
Allicin then breaks down into other smelly stuff that floats into the air and reaches your nose.
This is garlic's way of protecting itself from being eaten.
It also gives you garlic breath.
Chopping garlic releases alliin and alliinase, triggering a chemical reaction.
This reaction creates allicin, the primary compound responsible for garlic's smell.
Allicin breaks down into volatile compounds like allyl methyl sulfide.
This smell is a defense mechanism to deter animals.
The smell can result in garlic breath.
