In the autumn the leaves die back and the outer scales of the bulb
become dry and brittle, and this is the time at which the crop is
normally harvested. If left in the soil over winter, the growing
point in the middle of the bulb begins to develop in the spring.
New leaves appear and a long, stout, hollow stem expands, topped by
a bract protecting a developing inflorescence. The flower-head
takes the form of a globular umbel of white flowers with parts in
sixes. The seeds are glossy black and triangular in cross section.
Onion types and products
Common onions are normally available in three colours: yellow, red,
and white. Yellow onions, also called brown onions, are
full-flavoured and are the onions of choice for everyday use.
Yellow onions turn a rich, dark brown when caramelized and give
French onion soup its sweet flavour. The red onion is a good choice
for fresh use when its colour livens up the dish. It is also used
in grilling and char-broiling. White onions are the traditional
onions that are used in classic Mexican cuisine. They have a golden
colour when cooked and a particularly sweet flavour when sautéed.
While the large mature onion bulb is the onion most often eaten,
onions can be eaten at immature stages. Young plants may be
harvested before bulbing occurs and used whole as scallions. When
an onion is harvested after bulbing has begun but the onion is not
yet mature, the plants are sometimes referred to as summer onions.
Additionally, onions may be bred and grown to mature at smaller
sizes. Depending on the mature size and the purpose for which the
onion is used, these may be referred to as pearl, boiler, or
pickler onions, but differ from true pearl onions which are a
different species. Pearl and boiler onions may be cooked as a
vegetable rather than as an ingredient and pickler onions are often
preserved in vinegar as a long-lasting relish.
Onions are available in fresh, frozen, canned, caramelized, pickled
and chopped forms. The dehydrated product is available as kibbled,
sliced, rings, minced, chopped, granulated and powder forms. Onion
powder is a spice widely used when the fresh ingredient is not
available. It is made from finely ground, dehydrated onions, mainly
the pungent varieties of bulb onions, and has a strong odour. Being
dehydrated, it has a long shelf life and comes in several
varieties: white, yellow and red.
Nutrition and health
Most onion cultivars are about 89% water, 4% sugar, 1% protein, 2%
fibre and 0.1% fat. They contain vitamin C, vitamin B6, folic acid
and numerous other nutrients in small amounts. They are low in fats
and in sodium, and with an energy value of 166kJ (40 kcal) per 100
g (3.5 oz) serving, they can contribute their flavour to savoury
dishes without raising caloric content appreciably.
Onions contain chemical compounds such as phenolics and flavonoids
that basic research shows to have potential anti-inflammatory,
anti-cholesterol, anticancer and antioxidant properties.[medical
citation needed] These include quercetin and its glycosides
quercetin 3,4'-diglucoside and quercetin-4'-glucoside. There are
considerable differences between different varieties in potential
antioxidant content. Shallots have the highest level, six times the
amount found in Vidalia onions, the variety with the smallest
Some people suffer from allergic reactions after handling onions.
Symptoms can include contact dermatitis, intense itching,
rhinoconjunctivitis, blurred vision, bronchial asthma, sweating and
anaphylaxis. There may be no allergic reaction in these individuals
to the consumption of onions, perhaps because of the denaturing of
the proteins involved during the cooking process.
While onions and other members of the genus Allium are commonly
consumed by humans, they can be deadly for dogs, cats, guinea pigs,
monkeys and other animals. The toxicity is caused by the sulfoxides
present in raw and cooked onions which many animals are unable to
digest. Ingestion results in anaemia caused by the distortion and
rupture of red blood cells. Sick pets are sometimes fed with tinned
baby foods and any that contain onion should be avoided. Nor is it
good for pets to be fed onion-containing leftovers such as pizza,
canned spaghetti, Chinese dishes and onion rings. The typical toxic
doses are 5 g (0.2 oz) per kg (2.2 lb) bodyweight for cats and 15
to 30 g (0.5 to 1.1 oz) per kg for dogs.
In India, some sects do not eat onions as they believe them to be
an aphrodisiac. Various schools of Buddhism also advise against the
consumption of onions and garlic because they increase desire when
eaten cooked and anger when eaten raw.
Health benefits of Onions
- Onions are very low in calories (just 40 calories per 100 g) and
fats; however, rich in soluble dietary fiber.
- Phyto-chemical compounds allium and Allyl disulphide in the onion convert to allicin by enzymatic reaction when its modified leaves are distorted
(crushing, cutting, etc.). Studies have shown that these compounds
have anti-mutagenic (protects from cancers) and anti-diabetic
properties (helps lower blood sugar levels in diabetics).
- Laboratory studies show that allicin reduces cholesterol production by inhibiting the HMG-CoA reductaseenzyme in the liver cells. Further, it also found to have
anti-bacterial, anti-viral, and anti-fungal activities.
- In addition, Allicin also decreases blood vessel stiffness by releasing nitric oxide
(NO) and thereby bring a reduction in the total blood pressure.
Further, it blocks platelet-clot formation and has fibrinolytic
action in the blood vessels. Altogether, it helps decrease an
overall risk of coronary artery disease (CAD), peripheral vascular
diseases (PVD), and stroke.
- Onions are rich source of chromium, the trace mineral that helps tissue cells respond appropriately
to insulin levels in the blood. It thus helps facilitate insulin
action and control sugar levels in diabetes.
- They are an also good source of antioxidant flavonoid quercetin, which is found to have anti-carcinogenic, anti-inflammatory, and
- They are also good in antioxidant vitamin, vitamin-C and mineral
manganese. Manganese is required as a co-factor for anti-oxidant
enzyme, superoxide dismutase. In addition, isothiocyanate anti-oxidants in them help provide relief from cold and flu by
exerting anti-inflammatory actions.
- Onions are also good in B-complex group of vitamins like
pantothenic acid, pyridoxine, folates and thiamin. Pyridoxine or vitamin B-6 helps keep up GABA levels in the brain, which works
against neurotic conditions.
Selection and storage
Raw onions are readily available during all the seasons. Depending
on the variety, they can be sharp, spicy, tangy and pungent or mild
and sweet. In the store, they are available in fresh, frozen,
canned, pickled, powdered, and dehydrated forms.
While buying, look for fresh ones that are clean, well shaped, have
no opening at the neck and feature crispy, and dry outer skins.
Avoid those that show sprouting or have signs of black mold (a kind
of fungal attack) as they indicate that the stock is old. In
addition, poor-quality bulbs often have soft spots, moisture at
their neck, and dark patches, which may all be indications of
At home, store them in cool dark place away from moisture and humid
conditions where they keep fresh for several days. They can also
keep well in the refrigerator; however, you should use them
immediately once you remove from the refrigerator since they tend
to spoil if they kept at room temperature for a while.

Percentage of RDA
Chopping an onion causes damage to cells which allows enzymes
called alliinases to break down amino acid sulfoxides and generate
sulfenic acids. A specific sulfenic acid, 1-propenesulfenic acid,
is rapidly acted on by a second enzyme, the lachrymatory factor
synthase (LFS), giving syn-propanethial-S-oxide, a volatile gas
known as the onion lachrymatory factor or LF. This gas diffuses
through the air and soon reaches the eye, where it activates
sensory neurons, creating a stinging sensation. Tear glands produce
tears in order to dilute and flush out the irritant.
Eye irritation can be avoided by cutting onions under running water
or submerged in a basin of water. Leaving the root end intact also
reduces irritation as the onion base has a higher concentration of
sulphur compounds than the rest of the bulb. Refrigerating the
onions before use reduces the enzyme reaction rate and using a fan
can blow the gas away from the eyes. The more often one chops
onions, the less one experiences eye irritation.
The amount of sulfenic acids and LF released and the irritation
effect differs among Allium species. In 2008, the New Zealand Crop
and Food institute created a strain of "no tears" onions by using
gene-silencing biotechnology to prevent synthesis by the onions of
the LFS enzyme.
Storage in the home
Cooking onions and sweet onions are better stored at room
temperature, optimally in a single layer, in mesh bag in a dry,
cool, dark, well-ventilated location. In this environment, cooking
onions have a shelf life of three to four weeks and sweet onions
one to two weeks. Cooking onions will absorb odours from apples and
pears. Also, they draw moisture from vegetables with which they are
stored which may cause them to decay.
Sweet onions have a greater water and sugar content than cooking
onions. This makes them sweeter and milder tasting but reduces
their shelf life. Sweet onions can be stored refrigerated; they
have a shelf life of approximately one month. Irrespective of type,
any cut pieces of onion are best tightly wrapped, stored away from
other produce, and used within two to three days.

Onions are often chopped and used as an ingredient in various
hearty warm dishes, and may also be used as a main ingredient in
their own right, for example in French onion soup or onion chutney.
They are very versatile and can be baked, boiled, braised, fried,
roasted, sautéed or eaten raw in salads. Onions are also used as a
thickening agent for curries providing bulk. Onions pickled in
vinegar are eaten as a snack. These are often served as a side
serving in pubs and fish and chip shops throughout the United
Kingdom and Australia, often served with cheese and/or ale in the
United Kingdom. In North America, sliced onions are battered and
deep fried and served as onion rings.
Preparation and serving methods
Trim the ends using a sharp knife. Then peel the outer 2-3 layers
of skin until you find fresh thick pinkish-white whorls. You can
slice or cut them into fine cubes depending upon the recipe type.
Top greens and flower heads are also edible. Spring onions or scallions are favored in fast food preparations.
Here are some serving tips:
- They are used either chopped or sliced, in almost every type of
food, including fresh salads, or as a spicy garnish.
- In India and Pakistan, onions are one of the most sought-after
ingredients in cooking where they used in curries, stir-fries,
soups, stuffing, pastes, sauces, etc., everyday.
- They are one of the common ingredients in the Chinese "chowmein" (a
kind of recipe with chopped onions, scallions, cabbage, sweet bell
peppers, chili and tomato sauce mixture.
- They are used extensively in Mediterranean and continental cooking
in salads, cheese pizza, burger, soup, tart, rolls, stuffing...etc.
Raw onions can cause irritation to skin, mucus membranes and eyes.
