Many people know how uncomfortable that feeling of burning is that happens to your eyes when you are cutting an onion in the kitchen. Most people end up tearing up more while peeling and cutting onions, so that when someone comes in and sees them like this they may think that the person is going through a bad emotional time.

Why Does Cutting Onions Make Us Cry?

When you cut onions, they releases a substance called alliinase, which is what causes the emission of an irritating molecule called syn-propanethial-s-oxide or propanethial, which is a cause of eye irritation and tears. This molecule is a sulphurated essential oil, which is caught easily in the nose and irritates the nasal mucus. When you breath in propanethial, its irritating action causes that annoying tearing and burning in the eyes, that is often so bothersome, sometimes to the point that it makes you leave the kitchen to recover.

Since most people tend to cry when they have to deal with onions, today we want to share with you the best tricks so that you can learn how to cut onions without tearing upThese tricks are based on avoiding or reducing the emission of the volatile substance, as well as minimizing its effects.
