First of all, this is due to the fact that it contains a large amount, which is necessary to maintain the functioning of the reproductive system. Regular use soybean oil in food will help the absorption of this vitamin by the body by almost one hundred percent. In addition to vitamin E, soy vegetable oil includes components such as magnesium, potassium, vitamin C, calcium, sodium, phosphorus, lecithin. The composition also contains various fatty acids: linoleic acid, which is responsible for the prevention oncological diseases, as well as oleic, palmitic, stearic and other acids.

Accordingly, the beneficial properties of soybean oil include the fact that this product can be used to prevent kidney diseases, atherosclerosis. Soybean oil has a beneficial effect on strengthening the immune system and nervous system and also improves metabolism and improves metabolism.

Benefits of soybean oil

The benefit of soybean oil is a positive effect on the human body. Soybean oil is recommended for pregnant women, as it replenishes the necessary reserves. But expectant mothers should be extremely careful, and it is important to consult a doctor before use.

For prevention purposes, you can consume two tablespoons of soybean oil daily. Best added to salads fresh vegetables, soybean oil will perfectly complement the taste of tomatoes, cucumbers, bell peppers.

Soybean oil has a great effect on metabolism, strengthens the immune system and the nervous system. Scientists in the course of recent studies have concluded that this product prevents diseases associated with the heart.

Harm of soybean oil

People who are prone to allergic reactions and individual food intolerance should use soybean oil with caution. In addition, it is worth noting the fact that this product can harm mainly if the recommended consumption rate is not observed.

Soybean oil, despite numerous healing properties, not so often used in cosmetology. However, the reason lies only in ignorance of its amazing composition and the benefits of regular use. Having received complete information about the composition, properties and methods of using soybean oil, every woman will want to purchase this rich in nutrients and vitamins.

Composition of soybean oil

For the first time, the beneficial properties of soy and oil from it were noticed in China, where this product sprouted and was actively used in cooking. Over time, they began to obtain oil from ripe fruits, which has already received a wider use. Extraction of oil and its preparation is carried out by hot pressing. Then the refining process takes place. However, for use in cosmetology, it is better to use unrefined soybean oil.

The oil has a greenish-brown hue. In addition, he is not very nice smell and, consequently, taste. But correct application soybean oil brings one benefit.

Soybean oil is especially valued for a large amount of vitamin E in its composition. The advantage of this remedy is the presence of two types of this vitamin (E1 and E2). If you use only one type, then it will not be assimilated, however, in this oil, both forms are harmoniously combined. For comparison: in sunflower oil contains only 67 mg of vitamin E1, in - 13 mg, and in soy - 114 mg. As you can see, this oil is the undisputed leader.

Additional components of the oil are unsaturated acids, vitamin C, lecithin, potassium, phosphorus, calcium, sodium, magnesium. The presence of all substances causes the appearance of numerous useful properties oils, for which it is valued in medicine, cooking and cosmetology.

Despite the weak popularity in Russia, soybean oil is the first in the world in terms of annual production among vegetable fats. It is used in the food and agricultural sectors, as well as in some branches of the chemical industry. Soybean oil direct pressing is considered a very useful product with a high content of antioxidants, healthy fatty acids, lecithin, phytohormones.

For the production of vegetable fat from soybeans, mechanical and extraction methods are used. The first implies only spinning, and the second - an additional processing cycle on chemical equipment. In both cases, the seeds of the plant pass pre-processing which includes the steps:

Purification from mineral, organic and oil impurities.
Drying of raw materials to a moisture content of around 15%.
Separation of the seed and fruit coat from the nucleus.
Destruction of the cellular structure by grinding beans.
hydrothermal treatment.

Modern soybean processing plants use both mechanical pressing and extraction with organic solvents. The received products are packed and stored separately from each other.

Soybean oil of direct extraction has a rich biochemical composition, its beneficial properties are most pronounced. However, due to the presence of various components in the composition, it has a shorter shelf life.

The composition of soybean oil compares favorably with the composition of many other vegetable oils. First of all, it has a lot of vitamin E, which is necessary for sexual health, and consists of both forms - E1 and E2.

Today it is already known that vitamin E is “2 in 1”, that is, two forms of one vitamin: E1 - tocopherols (alpha, beta, gamma, delta), E2 - tocotrienols (the same designations). Both forms are necessary for the vitamin to be absorbed, and together they are present only in natural foods - there are no tocotrienols in pharmacy vitamins, which means that vitamin E is simply not absorbed from them.

But if you regularly use fresh food with this vitamin, including soybean oil, it will be absorbed by the body by almost 100% - the difference is obvious. Unfortunately, many doctors don't know about it (or don't even want to know).

Other components of soybean oil: vitamin C, calcium, sodium, magnesium, potassium, phosphorus; lecithin, saturated and unsaturated fatty acids. Most of all, linoleic acid - it can prevent the development of cancer; then come oleic, palmitic, alpha-linolenic and stearic.

These substances do not allow cholesterol to accumulate in the vessels, like lecithin; soybean oil can be used to prevent kidney disease, atherosclerosis, to strengthen the immune system and relieve the effects of stress; it improves metabolism and stimulates bowel function.

Is it possible to get soybean oil at home

Due to the low cost of soybean oil in retail chains, independent production this product is not very popular. Firstly, to obtain a high-quality liquid, you need to properly prepare the raw materials, squeeze, and then filter.

Second, it takes a lot of time. However, it is theoretically possible to squeeze fat out of soybeans at home. To do this, you will have to use a blender or meat grinder to get a wet slurry, from which the oil is then extracted using a colander and gauze.

Soybean oil is one of the most available products helping to lower the level of "bad" cholesterol. Accessibility means not only low price, but also widespread use.

Thanks to unique combination fatty acids pomace enhances the complex action of other useful substances preventing vascular and heart diseases.

As already noted, this is the closest vegetable oil to fish oil, which has a strong stimulating and normalizing effect on metabolism.

An important advantage of soy fat is high content alpha tocopherol, known as vitamin E. 100 grams of liquid contains 17.1 mg of this substance, which covers 114% of the average daily allowance consumption for an adult.

In addition, the composition contains zinc, which is important for the health of the skin, hair and reproductive system, and iron, which plays an important role in the work circulatory system. The above complex of fatty acids has a very broad effect, which positively affects the state of all internal organs and systems.

Soybean oil in baby food: harm and benefit

There is a wide variety of opinions about whether soy and products derived from it are good for baby food. Many parents are inclined to give a negative answer, citing the fact that a significant proportion of soybeans grown in the world are genetically modified varieties.

This is a true fact, however, such components are not included in products that are produced and imported to Russia, because this is prohibited by law. So there is no need to worry about GMO soy products.

Experts say that soybean oil does not have a specific effect on the child's body, but it is advised to include it in the diet on an ongoing basis from 1 year. A small amount of of this product in puree, porridge or salad will be useful due to the diverse fat composition.

For pregnant and lactating women use this product not contraindicated. But in order to avoid potential problems with the health of the child, one should consult on this issue with the observing doctor.

The beneficial effect on the body is expressed in the following effects:

the efficiency of metabolic processes increases;
toxins and slags are removed faster and better;
immunity is strengthened;
the work of the nervous system is stabilized;
the body (primarily the skin) experiences a rejuvenating effect;
the risk of development and complications of oncological diseases is reduced;
stabilizes the level of sugar and cholesterol in the blood vessels;
increases the productivity of brain functions;
improves the work of the gastrointestinal tract.

The described changes appear faster and stronger with the use of unrefined oil, because the refining of the product almost completely removes minerals and vitamins.

A key contraindication to the use of this product is individual intolerance. There are no specific restrictions, except for those that apply to any vegetable oils.

How to use soybean oil in food

AT Food Industry and home cooking soybean oil is used in unrefined, refined and deodorized form. The latter is the most versatile in terms of performance. It does not deteriorate or become harmful when heated during frying. But this is because it initially has rather limited useful properties.

Refined oil is also used for frying. It is convenient due to the fact that it does not “shoot” and does not splatter, and a soft crust forms on the surface of the meat.

Unrefined oil has the most useful composition. It is produced by direct pressing. This option contains more vitamin E and trace elements, but it can only be used without heating.

The smoke point of unrefined soybean oil is +160˚-+170˚C. When heated above this temperature, fatty acids are oxidized. This not only gives the pomace bitterness, but also leads to the formation of carcinogenic substances.

Can you fry with soybean oil?

Refined soybean oil can be used to fry fish, meat or vegetables. Its smoke point is +238˚C. The temperature of frying food in domestic conditions rarely exceeds +200˚C, so this does not lead to deterioration of the product and the formation of harmful substances. vegetable fat soybeans are also suitable for roasting and roasting in the oven or over low heat.

Using Hydrogenated Soybean Oil

Hydrogenation is the processing of vegetable fats with the addition of hydrogen atoms to the unsaturated double bonds of the main substance.

Figuratively speaking, this allows under pressure to create a homogeneous substance from oil, catalyst and hydrogen (initially, these components cannot be mixed with each other).

Hydrogenation technology has been known and widely used in our country since Soviet times. Today, fats converted in this way are called trans fats, and they have a very bad reputation.

Experts studying this issue say that the body has to absorb unnatural substances in the form of trans fats that do not exist in nature. It is assumed that they provoke unpredictable reactions in the body and increase the risk of developing:

oncological formations;
cardiovascular diseases;
obesity;
diabetes mellitus type I and II;
liver diseases;
disorders of the nervous system;
atherosclerosis.

Some studies show that people who regularly consume hydrogenated oils have a worsening hormonal background and metabolic disorders.

The product greatly helps in the fight for the health of the hair, when they are prone to excessive brittleness, dryness, thinning, split ends or damaged after intensive creation of complex hairstyles using synthetic substances (varnishes, mousses, etc.).

How to make a mask with soy oil for damaged hair:

For 1 share (5 ml) of lemon or lime juice, take 3 shares of soy and 6 shares of burdock oil.
Combine the ingredients, heat a little in the bath, distribute over the entire length.
Put a cellophane cap on your head and wrap a woolen scarf or scarf over it.
After an hour, wash your hair with a delicate shampoo.
Rinse a clean head with water with the addition apple cider vinegar, lime or lemon juice (15 ml per 1 liter).

To stimulate growth and strengthen hair, you can use an even simpler mask made from a mixture of soybean oil and castor oil. It is necessary to mix 2 tbsp, slightly warm and distribute over the roots and tips. The head also needs to be insulated over a plastic cap.

For dry hair:

Mix ¼ melted butter with 1 cup soy.
Apply over the entire length 20 minutes before shampooing.

For firming and moisturizing

Mix 1 tsp. soybean oil, 2 tbsp. onion juice and 1 tbsp. liquid honey.
Warm up a little before combining the products with each other. Apply over the entire length 45 minutes before shampooing.

Soybean oil in cosmetology

Soybean oil is among the available and inexpensive natural products, which can seriously help in the fight for the preservation of beauty.

It is well suited for the care of normal and dry skin, but not for combination or oily skin. The fact is that the remedy can stimulate the formation of excessive skin sebum, which in many cases worsens the condition.

Options for use in home cosmetic procedures:

Add a little pomace to the makeup remover milk to add a nourishing effect to it.
Enrich the composition of the product for tightening, rejuvenation, nutrition and recovery by adding a few drops before application.
Lifting mask. Mix ½ small apple with the pulp of 1 potato, cooked in their skins, and 1 tsp. soybean oil. After bringing to uniformity, transfer to the skin for 20 minutes.
Balm for dry skin. Apply at night a mixture of an equal volume of pomace of soybeans and peach pits.
An effective balm for sensitive skin is obtained from a mixture of olive and soy fats with chamomile ether.

The use of oil in industrial sectors

Food industry: production of margarines, confectionery, baking, bakery products.
Chemical industry: production of surfactants, thinners, emulsifiers, phosphate concentrates. Read more:

Storage conditions and shelf life

The shelf life of unrefined soybean oil is 1 year under the following conditions:

Temperature: +10˚C to +25˚C.
Relative air humidity: up to 85%.

The expiration date after opening expires after 6 months, but no later than the main period. When choosing in the store, you should give preference to the product in small glass bottles with tinted glass.

Nearly a hundred oilseeds are used by humans to produce different types vegetable oils. And soybeans are also on this list. However, it is not uncommon to hear that soy product not the most useful for a person. Is this true and what does official science say about soy fats? Now we'll find out.

general characteristics

The fact that oil can be obtained from soybeans was understood by people as early as the third millennium BC. And this discovery was made in ancient China. It was there that the most ancient written references to the use of the product were found. But according to experts, there is nothing strange in this, since it is China (according to some sources - and India) that is considered the birthplace of this culture. In ancient China, soy served as both food and medicine, and the plant itself was called divine. In those days, the East believed that soybean oil is the very elixir of youth that returns health, strength and beauty to a person.

Real soybean oil has a bright straw-yellow or greenish color and a specific pungent odor. In industry, this product is obtained by pressing (mechanical method) or extraction (chemical method). The most useful is unrefined oil obtained by double pressing (cold pressing). But you need to understand that this kind of product is not intended for long-term storage, it has a characteristic pungent odor and sediment. To extend the shelf life of the product, manufacturers resort to hydration, which, however, worsens biological value oils. But the consumer, as a rule, gets not pure oil, but refined - almost transparent, with a pinkish tint and already without a sharp aroma.

And Europeans learned about soy only in the 18th century. And first thanks soy sauce, which the French were the first to try in Europe. Today, soybean oil is made from the fruit of a plant known in biology as a cultivated plant. It is grown mainly in tropical and subtropical regions, as well as on Far East, in Moldova, Georgia. Soybean oil is one of the most popular among Chinese people, Western Europe and USA.

Chemical composition

According to scientists, soybean oil is the champion among food products in terms of the content of bioactive substances. But what is most impressive is that it is almost 98% absorbed human body, which is a very high figure.

Benefits for the body

Soybean oil has been used for therapeutic and prophylactic purposes for several millennia. And many of its properties, attributed by traditional healers, have already found scientific confirmation. For example, today it is known for sure that a soy product is useful for:

prevention of atherosclerosis and heart attacks;
strengthening immunity;
reducing the risk of malignant tumors;
improving bowel function;
lowering cholesterol in the bloodstream;
acceleration of metabolism;
improve blood clotting;
strengthening the nervous system;
prevention of disorders of the kidneys;
increase male fertility;
hair and skin care;
slowing down the aging process.

By the way, soybean oil is also useful in that it contributes to proper assimilation fat-soluble vitamins (, E, K).

But if the oil is intended for ingestion as a natural medicine, then its daily dose should not exceed 1-2 tablespoons.

What else is known about the benefits of soybean oil:

Regulates cholesterol levels

Cholesterol is a fat-like substance necessary for the body for the production of certain hormones and. organism healthy people is able to independently produce adequate doses of this substance, sufficient to perform its functions. Improper nutrition, disorders of the digestive system lead to excessive accumulation of cholesterol in the vessels. And this is a serious factor that increases the risk of developing coronary heart disease. The fatty acids contained in the soy product help the body control cholesterol levels and, in case of exceeding the permissible limits, reduce its concentration. Thus, it can be said that the soy product also protects against heart attacks and strokes.

Strengthens bones

This ability of the oil was due to the presence of vitamin K. This nutrient plays an important role in maintaining bone health. Studies have shown that vitamin K promotes bone mineralization, thereby preventing osteoporosis. And in addition to vitamin K, the product contains zinc and iron, which are also important for maintaining healthy bones and teeth.

Improves men's health

Soybean oil is considered beneficial for the prostate gland. The results of some studies indicate that the consumption of a soy product can reduce the risk of developing prostatic hyperplasia and cancer by almost 70%. In addition, soy oils help restore hormonal balance in the male body.

Source of Antioxidants

Free radicals, or reactive oxygen species, are generally part of normal oxygen metabolism. They are formed in the body when food is converted into energy, and it must be said that in a certain amount they are even beneficial for the body. Meanwhile, poor ecology, exposure to UV radiation, tobacco smoke and other factors increase the level of free radicals in the body, resulting in irreversible damage to cells and cell membranes. Therefore, a person needs substances that resist the aggressive effects of reactive oxygen species. And such substances are. Vitamin E found in soybean oil is one of those. Sufficient intake of this nutrient prevents the excessive formation of free radicals, and also prevents diseases caused by them (including cardiovascular, oncological). In addition, vitamin E effectively strengthens immune system, promotes the formation of red blood cells and improves the absorption of vitamin K. And soybean oil can serve excellent source antioxidant vitamin.

Possible harm and side effects

In addition to the benefits, soybean oil can also harm the body. For example, people who are allergic to soy, this product is strictly prohibited. It is believed that the soy product is undesirable in the diet of pregnant and lactating women, as it contains a lot of estrogen-like isoflavones. And some researchers suggest that against the background of consumption of soybean oil, migraine attacks are possible. Well, do not forget about excessive weight, which is also inevitable if you are very fond of this high-calorie product.

Another fact why researchers look at soybean oil with caution is the high content of omega-6 fats. Excess of these fatty acids in the body can cause inflammation and chronic diseases.

The most dangerous is called the oil obtained from genetically modified beans. Such a product, as a rule, contains many components dangerous to humans. For example:

goitrogens - substances that block the synthesis of thyroid hormones (produced by the thyroid gland) and interfere with metabolism;
genistein and daidzein are phytoestrogens that can disrupt endocrine system, cause infertility, promote breast cancer;
phytic acid - impairs the body's absorption of iron, zinc, and some others useful minerals(soybean is the leader among all legumes in terms of phytate content, their concentration can be reduced by long heat treatment);
hemagglutinin - causes aggregation of red blood cells.

Use in the food industry

Soybean oil is one of the leaders in its use in the food industry. It enters the kitchen either in liquid form (refined) or as a component. This oil can often be seen on the ingredient list of many products, including confectionery, mayonnaise, salad dressings, soy milk. In addition, it is used as a stabilizer and preservative in canned food, as well as for processing products before freezing.

According to the rules, a vessel with soybean oil should be stored in the refrigerator. Under the influence of the sun, its beneficial properties are reduced. In addition, the soy product is not intended for long-term storage (maximum a month), so it is better to buy in small portions.

Use in cosmetology

Many centuries ago, the soy product was used as a natural cosmetic product. it fatty oil has many benefits for dry and normal skin. It moisturizes and nourishes it, creates a protective barrier on the epidermis, which helps to retain moisture. Soy oil-based products are useful for caring for very dry, chapped and rough skin. This vitamin E-rich product is important to include in your aging skin care program. It will help keep the face in good shape, slow down aging, and restore the natural color and smoothness of the skin. In the composition of soybean oil, the researchers found lecithin, which is extremely important for the skin, especially for dermatitis. In addition, soybean oil is useful to apply to insect bites to get rid of itching and swelling.

However, the use of soybean oil can also cause unpleasant side effects in the form of comedones (black dots on the skin). This most commonly occurs as a result of using undiluted soy products. Therefore, for the face, it is better to take a mixture of oils, for example, from soybeans, almond and peach seeds, pine nuts and other plants. A few drops of soybean oil can be added to ready-made purchased creams, lotions for the face and body, milk for removing makeup.

Soy product is also useful for accelerating hair growth. It is useful to add a few drops important for hair to the oil base. essential oils(such as mint, lavender, or rosemary). The mixture is applied to the scalp, and then wrapped with polyethylene and a warm towel.

What else is useful

The fact that soybean oil contains lecithin, we have already said. And this feature made it possible to use a soy product in pharmacology. Also, the benefits of oil are obtained in soap making, in the manufacturing process. detergents, plastics, dyes, synthetic oils. And not so long ago, researchers discovered that a soy product in pure form(as, by the way, rapeseed) is excellent remedy to control garden pests.

Scientific disputes on the benefits and harms of soybean oil have been going on for years. One group of scientists claim that it is one of the healthiest foods, others argue that, apart from the low cost, there is no other reason to use soybean oil in food. Which of them is right will probably be judged by time and subsequent studies of useful and hazardous properties this product. In the meantime, we can only say with certainty that it, like other oils, should be consumed in moderation. After all, even the most healthy foods in excess can be harmful.

From soybeans, a very rich in color, liquid and flowing soybean oil, which is easily distributed over the skin, is extracted, which has a whole range of healing and cosmetic properties. In the Far East, it is the leader among plant bases; it is actively eaten. This is an affordable, but no less valuable base, perfectly revealing its antioxidant and anti-aging properties on dry skin. The good fatty acid composition of soy provides it with high anticholesterol activity. it excellent foundation for use in various aromatherapy techniques.

What to look for when buying oil

Soybean oil is produced in such quantities and is so popular that it can be found in literally any grocery store. In Korea, Japan and China, this base is generally considered the leader among vegetable oils used both for food purposes and in the cosmetic industry.

It is represented almost as widely as the established favorites among base oils: It can be found in pharmacies, specialized resources, grocery stores. But when buying, it is extremely important to carefully check all the information, because there are products on the market with a wide range of prices and quality.

Along with soybean oil itself, there are so-called cosmetic soybean oils on sale, in which other bases are present in the amount of a ten percent additive, most often or. Such products cannot be considered a full-fledged analogue of pure oil, since they have many additional characteristics and properties. It is difficult to judge the scope and methods of their application, each specific case requires studying the manufacturer's instructions.

Name and markings

This oil is distributed only under the name "soybean oil" or "soybean oil". Even foreign names are also very limited, markings are usually found soybean oil, « glycine hispida oil, « soya oil".

In our country, soybean oil is often distributed simply as "vegetable oil", but palm-derived products can also be purchased with the same name. Therefore, it is necessary to carefully compare the plants used in the production of oils.

The oil must contain the Latin botanical name of soybean - glycine max.

Plant and regions of production

Soy has become famous as a plant-based meat substitute due to its more than 50% protein content in its composition. It is an annual herbaceous leguminous plant, which uses mature seeds for oil production and food purposes, better known as soybeans (however, calling them beans is not entirely correct from a botanical point of view).

Soy is grown literally everywhere the globe. One of the most ancient cultivated plants is also considered one of the most valuable industrial and nutritious crops of our time. The United States, Brazil and Argentina remain the world leaders in industrial plantings, although every year the share of Asian and Russian market soybeans are growing.

There are no restrictions on oil production regions, as well as a difference in quality between soybean oil obtained in European countries, America and here. Ultimately, the quality of a product is always determined by the extraction technologies used, the degree of refining and purification, and the integrity of the manufacturer.

falsification

Soybean oil is produced in large quantities, but the difference in the quality of the oil itself, how it is extracted and the composition makes the search process really quality product complicated enough. It is often substituted in food line products palm oils, whose composition and characteristics are radically different.

When buying this oil, you need to carefully check the raw materials used and the method of production, the degree of refining, but still the main attention should be paid to the composition of the oil and the methods of its use recommended by the manufacturer.

Receiving Method

The variety of soybean oils on the market is largely due to completely different production technologies. They are obtained by several methods, while the presence or absence of subsequent processing and purification leads to an almost drastic change in the characteristics of the base.

Soybean oil is extracted from whole or pre-crushed ripe seeds, peeled. Due to the relatively low yield of cold-pressed oil and the consequent increased cost of production, the more efficient extraction method with organic solvents (usually hexane) is increasingly being used today.

Before extraction, the seeds are heated to an average of 75 °C to coagulate. soy protein and facilitating the further process of oil extraction. The oil obtained by this method is always refined, the unrefined product can only be used for technical purposes. Refining involves cleaning of varying degrees of complexity, it is usually supplemented with deodorization.

In the production process, raw soybean oil is used to obtain lecithin, which it contains up to 3%.

According to GOST 31760-2012, the following types of domestically produced soybean oil suitable for human consumption can be distinguished:

unrefined premium obtained by cold pressing. It is it that is considered the highest quality, most fully preserving all the useful characteristics.
Refined and deodorized oil obtained by extraction, which is of the highest and first grade.
Hydrated (provided it is obtained from cold-pressed oil). Hydration is a physico-chemical refining method in which unwanted impurities are removed with water. Thus, valuable phospholipids, including lecithin, are isolated from the oil. Soybean oil purified in this way is deprived of all useful properties; it is not recommended to use it for culinary and aromatherapy purposes.

Other species are used only for technical purposes for industrial processing, they cannot be used in cooking and in aromatherapy methods.

Soy is actively used in the production of margarine, using hydrated oil for this purpose. Hydrogenation converts vegetable oil from liquid state into a solid, increases its stability and shelf life. However, soybean oil, during the hydrogenation process, forms a large amount of trans fats (trans fatty acid isomers), the use of which leads to an increased risk of cardiovascular disease. It is better to refuse the use of such margarine.

Characteristics

Compound

The chemical composition of soybean oil is quite complex. Its characteristics are largely determined by the fatty acid composition. About half of the volume of the oil is linoleic acid, about a quarter - oleic, up to 12% - palmitic, up to 8% - alpha-linolenic, up to 6% - stearic. The proportion of saturated fatty acids is negligible, which makes it possible to classify soybean as a cholesterol-free vegetable oil.

The unique characteristic of this oil is the presence in the composition of acids characteristic only of fish fats, so soybean oil can act as an alternative in the treatment of cardiovascular diseases.

One of the most valuable characteristics is the presence of lecithin in the composition (of course, in the absence of deep purification, which deprives the oil of such an important component). Soybean oil also contains calcium, magnesium, potassium, sodium, vitamins P, C, E.

Color and fragrance

Soybean oil is quite easy to find by appearance. It is liquid, flowing, transparent, well capturing and reflecting light, beautifully iridescent, not at all dense, in consistency it resembles common edible vegetable oils.

The color of this oil is one of the most beautiful among all the bases. Saturated, bright, clean and thick amber hue is very noble, thanks to it soybean oil resembles liquid gold. True, it should be clarified that a beautiful amber color is characteristic only for the quality oil, obtained by pressing, which has not been refined and has not lost its taste and smell along with the color. The more the product is cleaned, the more it loses its color: the bases of repeated cleaning almost completely lose their smell and taste.

The aroma of soybean oil, despite the fact that the plant itself belongs to legumes, is by no means unpleasant and almost unrecognizable, devoid of shades specific to all soybean products.
