ONION



Indeed, what is the power of an onion that able to make every housewife ‘CRIES’ in the kitchen??? And what are the uses of onion contributing to our daily life???

Onions are the most common types of vegetables and that have embellished the kitchen shelves for every home. Onions are very common and good ingredients that contribute flavor to the food and even bring ‘TEARS’ in our daily life.

There are many question marks arose by the housewives??? Why does cutting onions always make our eyes tearing?

Here, let me tell you the secrets behind an onion. LISTEN, LISTEN, LISTEN……

When an onion is sliced, the onion cells are being broken. At the same time, the enzymes inside the onion cells called alliinases, which break down the amino acid sulfoxides and thus generate sulfenic acids. A specific sulfenic acid is recognized as 1-propenesulfenic acid.

The 1-propenesulfenic acid is then rapidly rearranged by a second enzyme, lachrymatory factor synthase (LFS). As a result, syn-propanethial-S-oxide is formed, a volatile gas known as the onion lachrymatory factor (LF).

Hence, the LF gas diffuses into the air and reaches the eye in time and lead to the activation of sensory neurons. Finally, the nerves around the eyes are irritated and make us cry automatically.


Onions make us down and cheer. Never mind the tears they bring on. However, they are the prized members of lily family, which they have the great contributions to our daily life.
