Soybean oil: types, properties and subtleties of application
The first mention of soybean oil came from East Asia and is dated to the third millennium BC. But despite the impressive age, this is a fairly new product for modern industry. Due to the unique composition of soybean oil has been widely used in cooking, and in folk cosmetics is one of the first places. It is used as an independent tool, and as part of a variety of cosmetic preparations.
What it is?
Soybean oil refers to the type of vegetable oils. It is a liquid transparent product with a shade from yellow to brown and with a characteristic odor. Eco-friendly, has no synthetic analogues, is absorbed by the body by 98%.
Modern industry produces products produced in two ways.
- Extraction with chemical oxidants. This is one of the most popular ways to get essential oils. It is ergonomic, has a large yield of the final product. But this method has a significant drawback - the presence of residual chemicals. This oil is better to use for external use.
- Pressing is a mechanical production method. The oil produced in this way has several advantages: it contains more vitamins and microelements, but it has a pronounced sharp odor and a short shelf life. Cold-pressed oils are not recommended for heat treatment. At high temperatures, the nutrients are destroyed.
Double pressing is one of the most popular ways to produce soy extract. It allows you to maintain the beneficial properties of the original product without chemical exposure, which significantly increases its useful qualities. Cold-pressed oil is considered to be the most useful, but not everyone will like its smell. More often it is used as a food additive or for cosmetic purposes.
Soybean oil accounts for 70% of all produced vegetable oils in the world. It is most common in China, Japan, and the USA. In most Asian countries use it on a par with sunflower and corn.
Types and composition
Depending on the production method, the oil is divided into:
- refined;
- deodorized;
- refined deodorized;
- unrefined.
More often it is used as a food additive, for the production of margarine, mayonnaise, non-dairy cream, widely used as a preservative and stabilizer in the production of canned food, for freezing food products.
In the production of crude soybean oil does not use chemical solvents and catalysts. It is an environmentally friendly product, rich in vitamins, phospholipids, phytosterols and organic acids. It is a natural antioxidant, used in cooking, diet and cosmetics. This is a great addition to salads, it is indispensable for the nutrition of athletes, but is unsuitable for culinary processing. On this oil, it is not recommended to extinguish or use it for deep-frying. Unrefined oil when frying burns, foams and smokes, in addition, it produces toxic and carcinogenic substances.
Refined deodorized oil by the number of useful elements is significantly inferior to unrefined. It is used for cooking. It is used when frying, for baking bakery products, making homemade mayonnaise. It does not burn, has almost no odor, is resistant to high temperatures, emphasizes the taste of vegetable salads, gives a rich savory flavor to fried, stewed dishes. The oil is able to retain its qualities and aroma for several months if properly stored.
Refined non-deodorized oil is used for industrial purposes, and the hydrogenated oil undergoes a special treatment, as a result of which the tendency to the formation of bitterness is reduced. The cause of rancid are unsaturated fatty acids, which, upon contact with air, acquire a bitter taste. During the hydrogenation process, the oil is heated to a high temperature followed by the addition of a catalyst and hydrogen. After careful filtration, a hydrogenated product with a characteristic dense texture is formed, which is important in the production of solid fats. Soy extract significantly exceeds the composition of sunflower, rapeseed and flaxseed oils. Its caloric content is 899 Kcal, fat - 99.9 g, water - 0.1 gram.
Soy extract is a real record holder in the content of lecithin, which is extracted from fatty acids. Fats of soybean oil are polyunsaturated fatty acids, half of which is linoleic, and 25% is oleic. Stearic fatty acid is 6%, and palmitic by 5%. The saturation of fat in 100 g of the product contains:
- polyunsaturated fat - 58 g;
- saturated fatty acids - 16 g.
In addition, the composition of soybean oil includes fat-soluble, water-soluble vitamins and trace elements.
- Vitamin E (8.18 mg) - One of the most important elements for the health and attractiveness of the body. Participates in redox processes, prevents the destruction of red blood cells. Reduces the permeability of large vessels and capillaries, normalizes the work of skeletal muscles, activates the processes of phagocytosis (absorption of harmful substances), normalizes hormonal, reproductive function and slows down the processes of cell aging.
- Vitamin K (184 mg) participates in the process of anaerobic respiration, increases blood clotting, enhances the formation of prothrombin, normalizes metabolic processes. Vitamin K is an essential element of bone tissue formation, it prevents the destruction of osteocalcin and prevents the development of osteoporosis, especially during menopause.
- Vitamin B4 (0.2 mg) is a precursor of acetylcholine in the body, regulates metabolic processes, improves the functioning of brain neurons, enhances memory and reaction, prevents the development of sclerosis and Alzheimer's disease, is responsible for tissue regeneration and slows down the processes of cell aging.
- Iron (0.05 mg) It is a catalyst of metabolic processes in the body, plays an important role in metabolism, participates in the transport of oxygen, is part of the vital enzymes and protein fractions, and promotes the utilization of toxins and harmful substances. It also activates protective functions, strengthens the immune system, restores strength after physical exertion and nervous exhaustion.
- Zinc (10 mcg) normalizes the development of bone tissue and stimulates cell division and formation. It contributes to the normalization of the nervous system, accelerates the transmission of impulses to brain cells, strengthens the immune system, stimulates phagocytic activity, and normalizes the functioning of the hormonal and reproductive systems.

In industry, the oil is used for the oxidation of polyvinyl chloride products. In this area, it is called epoxidation and is used to stabilize polymers as an independent substance, and in combination with other components. It is used for the production of medical, food products, cables and plastic.
Harm
Even the most useful product has a number of contraindications, and soy extract is no exception. It is not recommended to use it:
- with intolerance to individual components of the product or allergic reactions to soy protein;
- lactating women in the first half after the birth of the child due to the high content of estrogen in the composition of the product;

People suffering from overweight are advised to eat the amount of product strictly recommended by a nutritionist, and with a strict diet one should refuse to eat oil in general.
How to choose?
Vegetable oils - a necessary element of any diet, the choice of which must be approached with close attention. Supermarket shelves are full of an abundance of diverse products, and often the well-known brand, brand, price, and, last but not least, product quality often become the main reference.

Manufacturers of Russia according to GOST packaged oil in any container, but it is better to give preference to glass packaging. It does not oxidize, does not transmit sunlight and retains the original quality of products.
The label indicates the scope, classification, technical requirements. At external examination slight turbidity or a slight sediment is allowed. Large flakes, the presence of liquid, dot blotches indicate the unsuitability of the product. On the packaging indicated the characteristics, composition, labeling and methods of control products. All data should be well read, complete and not washed away. This protects the buyer from counterfeiting and guarantees the purchase of quality products.
Application
Soybean oil is successfully used in many areas, and traditional medicine and cosmetology have long been adopted its useful properties. It is used in the composition of the masks.
