What is red onion and how is it different from regular onion? Is it true that he is sweet? These and many other questions occupy gardeners who plan to plant such onions.
Description
Red onions belong to the Onion family. It is called so because of the bright color of the husk, the shade of which can range from pale to deep burgundy. Interior It has more of a purple tint. Like other types of onions, it has a low calorie content (per 100 grams of product). Nutritional value – 42 kcal, most of it comes from carbohydrates. Their content is 9.2 g, protein – 1.7 g, fat – 0.1 g.
In appearance and taste, the purple vegetable differs from the white and yellow ones. The first difference is the bright husk and the purple-red hue of the pulp. Red onions are less hot, do not burn the mucous membranes, they are sweeter and more tender compared to the universal yellow onion. This, in turn, led to its frequent fresh consumption - it is usually added to salads.
White onions are characterized by greater sweetness compared to all-purpose onions. It is similar to sweet varieties of red onions, but, unlike them, does not have spicy varieties. White onions have the shortest shelf life compared to the species considered.
Red onion is considered a biennial herbaceous plant. The diameter of the bulb is 12-15 cm. The weight of the head is 65-76 g. Buds are formed on the stem, from which daughter bulbs then develop.
In general, the taste of red onions depends on its variety, where it is grown and how it is cared for. So, the sweetest is the Crimean red onion, which the residents of Crimea eat separately from other dishes. This variety, grown in the area between Yalta and Alushta, is a delicacy.
Benefits and harms
The beneficial properties of red onion are due to its composition - it is rich in B vitamins, vitamins E, PP and ascorbic acid. In addition, it contains micro- and macroelements useful for the human body, including iron, magnesium, zinc, sodium, phosphorus, potassium, and calcium. Finally, the vegetable contains biologically active flavonoids, in particular allicin and quercetin.
The bright color of the vegetable is due to the presence of anthocyanins, which have antiviral and antifungal effects. In addition, it is believed that these substances are preventive in the fight against oncology, diabetes, and central nervous system disorders. Finally, they (in combination with vitamin E) stop and slow down the aging process.
Sulfur, which the red-violet vegetable is rich in in various compounds, also has a rejuvenating effect. Sulfur has the ability to remove toxins from the body, stimulates collagen synthesis, which, in turn, is responsible for skin elasticity, and has a positive effect on the condition of hair and nails. By the way, the latter effect is also due to the presence of zinc in the vegetable.
Finally, sulfur promotes healthy blood vessels, as it destroys and prevents the appearance of new cholesterol plaques on the vascular walls. Thanks to this, the risk of developing varicose veins, heart attacks, strokes is reduced, tissues and organs receive the necessary amount of oxygen.
Rich in vitamin C, red onions will help fight colds and vitamin deficiency. It helps strengthen the body's immune forces. It must be included in the diet during seasonal respiratory diseases, as well as in late winter and early spring. In addition, purple onion juice has a disinfectant effect, which allows it to destroy bacteria and viruses.
Research shows that the vegetable promotes testosterone production and increases libido. Men are recommended to add it to their usual dishes.
It is a misconception that red onions have a sweetish taste due to the presence of sugar. This is not true; the bitterness of onions is due to the essential oils they contain. The greater their number, the sharper and more “tear-producing” the vegetable is. In sweet varieties the amount of these essential oils is minimal.
Due to the high content of essential oils and acids, consumption of onions should be avoided during periods of exacerbation of diseases of the gastrointestinal tract (gastritis, ulcers, pancreatitis). If you have chronic diseases of these organs, you should also reduce the amount of red onion consumed.
If you have an individual intolerance, you cannot eat the vegetable. It is worth refusing to consume it if you have liver and kidney disease, as well as with acute forms of diseases of the urinary system. If you have asthma or hypertension, you should be careful when including red onions in your diet.
For pregnant women, the red vegetable is useful because it contains folic acid, which is so necessary for the normal development of the fetus. In addition, due to the content of B vitamins, onions have a beneficial effect on nervous system, normalizes sleep. However, pregnant women should eat it with caution and in small doses for the same reason - essential oils irritate the already vulnerable intestines and gastrointestinal tract expectant mother. In the first trimester, you are allowed to consume 100 g of onions per day, in subsequent trimesters - reduce to 50 g.
When breastfeeding, red onion in small doses is allowed for use, if it does not cause negative consequences for the child's health. Onions, including red ones, contribute to the formation of gases, so most nursing mothers are forced to temporarily stop eating them.
In any case, you should not eat onions in their pure form, as this can cause heartburn and stomach pain. You should not eat onions on an empty stomach.
People suffering from flatulence should not eat the red vegetable raw, as it is a gas-forming product.
Varieties
There are several varieties of this onion, one of the most famous of them is the Crimean onion. It is so sweet that the inhabitants of the peninsula consume it like apples. As already mentioned, this onion variety was originally grown in the area between Alushta and Yalta. In this case, it acquires unprecedented sweetness and juiciness. Onion heads are quite large; they are used fresh in salads, and also caramelized and served as a dessert.
Red Baron has a bittersweet taste. It is distinguished by a high content of ascorbic acid, as well as the ability to be stored for a long time, maintaining the same taste and composition. Such bulbs are universal - they are eaten fresh, used for preparing first and second courses, and sauces.
Another variety that can be stored for a long time is Brunswick. Refers to late-ripening, onion heads are medium-sized flattened “balls”. The rich red onion “Greatful Red F1” also demonstrates good shelf life. It is also distinguished by fairly large bulbs, the weight of which can reach 130-140 g. By the way, it can be found in the windows of most supermarkets - it tolerates long-term transportation well, is stored for a long time and has a pleasant sweetish taste.
If you want to start enjoying red onions in early August, choose early-ripening varieties, such as “Red Ball,” which is also famous for its high yield. From the name of the variety it is clear that the crop has the shape of a regular circle and a rich purple hue. This variety is best consumed fresh.
For growing on your own plot, especially if you are new to this business, we can recommend the Campillo F1 variety, which is relatively unpretentious in care and resistant to diseases characteristic of the crop. The harvest will delight you with a beautiful purple hue and delicate taste.
The external similarity and the same sweet taste as the “Campillo F1” variety are revealed by the “Retro” onion. This early-ripening variety is optimal for fresh salads. Thanks to the sweetness of the bulbs, they can even be used in dishes for children. By the way, the “Retro” variety, like “Yukont”, is suitable for annual cultivation. The latter produces a fairly pungent harvest that can be stored all winter.
“Red Semko F1” demonstrates similar unpretentiousness and productivity, producing flat, medium-sized bulbs. If we compare it with the blue and purple varieties, then in cross-section it has white flesh with red streaks along the edges of the rings.
But lovers of red onions with a pleasant bitterness will probably like “Red Braunschweig”, which is classified as mid-season. Its advantage is its uniform germination and unpretentiousness during the growing season. The “Black Prince” variety surprises with its rich dark red shade, turning into burgundy. It has a semi-sharp taste, demonstrates good keeping quality and versatility.
Planting and care
The taste and sweetness of onions largely depend on the characteristics of the soil and temperature conditions. Since the crop is involved in crop rotation, the best soils for it will be those on which nightshades were previously grown - tomatoes, potatoes, zucchini.
You should choose well-ventilated (but windless) areas that receive sunlight most of the day. You need to start preparing the soil in the fall - dig it up, apply organic and mineral fertilizers. In the spring, the soil is dug up again. Red onions grow best in fertile sandy loam soils.
Planting onions can be divided into 2 stages - planting onion seeds in a greenhouse, and after a set of these seeds appears, transplanting it into a garden bed and further cultivation. You can buy seedlings and immediately plant them in the garden, but there is a high probability of buying seed material that is not resistant to infections. Careless sellers often get the bulbs confused, so the variety that grows is not the one the gardener expects.
Onion seeds need to be sorted, removing empty and defective ones, and then disinfected in a weak solution of potassium permanganate. To do this, dissolve 1 g of potassium permanganate in a glass of warm water. Soak the seeds in this solution for 15-20 minutes, then rinse under water and dry. It is more convenient to wrap the seeds in a gauze bag.
The prepared seeds are planted in the ground in a greenhouse or at home under film in early spring. For seedlings to appear, the ambient temperature must be at least 25 degrees.
After collecting the seedlings, they are disinfected again by soaking them in a weak solution of potassium permanganate, the tops are cut off (this improves growth) and planted in open ground. Do not plant weak bulbs damaged by rot or disease. By this time, night frosts should stop, and the soil temperature should be at least 15-17 degrees.
Typically, red onions are grown in beds, first making furrows on their surface every 20-25 cm. The step between the bulbs is 4-5 cm.
The “Chinese” method of growing red onions is also popular, according to which you need to make high beds. The latter are washed away after a while under the influence of rain, and upper part the bulb (which has already managed to get stronger and adapt) opens. In this form, the plant receives more solar heat and light, nutritional components, which has a beneficial effect on its growth.
Further care of the plant cannot be called difficult, but to obtain a good harvest It is important to regularly follow the following agrotechnical recommendations:
Evidence that the onion is ready for harvest will be yellowing and lodging of the green arrows. It is important to prevent the onions from flowering, as the harvest will not be able to be stored. If you find similar arrows in the garden, pull out the onion and eat it as soon as possible.
You will learn more about how to grow red onions in the following video.
The harvested crop must be dried during the day, without, however, placing it in direct sunlight. It is optimal to harvest the crop in the first half of the day (necessarily in dry weather) and put it to dry, for example, under a canopy until the evening.
After this, cut off the arrows (if this has not been done previously), leaving them at 5-7 cm, tie several bulbs together “in a bunch”, which are hung in a well-ventilated place protected from UV rays. In this form, the onion should be dried for 2-3 weeks, then inspected, cut off the dry arrows, leaving a 2-2.5 cm “tail”.
Now the onions can be transferred to boxes for further storage. If you plan to store onions all winter until the next season, it is important to choose a suitable variety that has good shelf life. For example, Yalta red onions are not very suitable for these purposes, since they are stored for no more than four months.
It is important to ensure optimal temperature conditions. The permissible storage temperature range is -3… +10 degrees. Sweet red onions are best stored at 0 degrees.
Another important condition is good ventilation. Finally, air humidity should not exceed 80%. If one of these requirements is not met, the onion begins to quickly deteriorate, losing its taste and benefits.
Onions should not be stored in plastic bags. Preference should be given to wooden boxes, wicker baskets, cardboard boxes, and fabric bags.
You can use a cellar for storage. If we are talking about storage in an apartment, shelves on the mezzanine, a balcony where the temperature in winter does not drop below 0, as well as the lower shelves of the refrigerator are suitable. You can put the heads in nylon tights or stockings the old fashioned way. In this form, the onion will be protected from moisture, and air circulation will not be impaired.
Before storing the vegetable, you should dry it well and remove damaged heads that are prone to rotting.
