What is Onion?
Onion (Allium cepa), the bulbous flowering plant,is a vegetable and it is widely cultivated for its edible onion bulbs. Other names include onion grass, shallot and multiplier onion. As one of the oldest vegetables known to man, onion has been used as both food and medicine since ancient times.
The word “onion” comes from French ‘oignon’ that came from Latin “unio” which means single bead. The onion was named after an old Egyptian pyramid because it grows in layered structure like a pyramid or onion layers. Each layer can be harvested separately over a period of time extending up to 10 months which explains why they are so cheap at grocery stores during some seasons.
Onion is closely related to garlic and both are originally native to Central Asia, although they have become widely cultivated all over the world. The onion was first recorded in history by French botanist Tournefort during 1699-1700 when he traveled through Persia (Iran) and wrote about onion’s growth in eastern Mediterranean region where onion was already a staple food before 3000 BC. The oldest onion remains were discovered near modern-day Esfahan city in Iran from Bronze Age settlements dating between 2900 – 2350 BCE.
In onion field, there are many layers of skins which protect onion from insect attacks and keep moisture inside the onion called epidermis or tunica externa. There is a thin layer below onion epidermis called tunica media or albedo.
There is another layer under onion’s albedo which is called tunica interna of onion bulb and this layer is the thickest layer with a very strong cellular tissue where onion stores most of its nutrients. Onion cells divide rapidly in tunica interna and they produce more layers which results in onion bulb growth. On the other hand, onion leaves have hollow air filled stems to help them grow taller without being too heavy as onion bulb.
They don’t store much water because air takes lots of space inside onion stem as well as inside onion leaves. In addition, there are two types of onion bulbs: dry type and fresh type determined by during storage after harvest where fresh onion types have a wet surface or dry onion types have a dry surface.
