What is the difference between refined oil and unrefined oil?

Different types of oils are widespread.Most of them are used in cooking when cooking, and they are also used in cosmetology for skin and hair care and in traditional medicine. Today, refined and unrefined oil can be found on the shelves (the word "refined" means "refined").

For the production of vegetable oil is taken various raw materials - it can be sunflower seeds, fruits of olive, corn or rapeseed. Depending on the method of obtaining refined and unrefined oils are allocated.

Both products have a common initial production scheme. It includes the following steps:

• cleaning of raw materials from mechanical impurities by the method of separation in special equipment;
• hulling and peeling sunflower seeds from the husk (in the production of sunflower oil);
• crushing of fruits on roller machines to get a mint;
• heating of the raw material and its subsequent supply to the screw pressing equipment;
• settling and filtering.

So get unrefined oil. Finished products are bottled and sold. In order to obtain a refined product, unrefined oil is subjected to further treatments:

• heat to extract phosphatides;
• extraction of free fatty acids using a chemical method;
• deodorization - the process of removing pigment substances, carotenoids, volatile compounds and some other components;
• freezing - a process that ensures complete removal of wax from the product.

So get refined deodorized oil. Partial similarity of the purified and unpurified product lies in their composition. For example, there are polyunsaturated fatty acids, vitamins and nutrients in both. However, in the refined product they are much smaller.

The difference between refined and unrefined oil is huge. Before proceeding to the implementation, the refined product undergoes multi-stage processing. As a result, an odorless clear and transparent liquid is obtained at the outlet. It is worth noting that during cleaning, almost all valuable and nutritional components for the human body are removed from the oil. It remains a clear liquid with a lubricating effect, softening properties and anti-adhesive effect. In addition, the differences of refined oil from unrefined oil are in some factors.

• In a more "marketable" form. The purified product has a light golden uniform color. Unrefined oil has a darker color, and during storage it can form a precipitate.
• In the absence of smell. Due to the deodorization process, the purified product completely loses its flavor, which is why it does not change the taste of the dishes prepared with it. Unrefined oil with a smell can smell like seeds, corn, sesame (depending on the base used in production). Due to the specific flavor, it is not suitable for all dishes - most often it is used to prepare vegetable salads.

• In resistance to heat treatment. Refined oil is ideal for frying or deep-frying. An unrefined product is not recommended to be heated, as it starts to foam and chad during thermal exposure, actively releasing carcinogens.
• In the loss of beneficial properties. Due to the refining, almost all substances are removed from the product: both harmful and useful (vitamins, phosphatides, micro- and macroelements, omega-3 and omega-6 acids). Of the advantages of refining, it can be noted that there are no pesticides in the purified product - substances harmful to human health, which are often used in growing crops.

In addition, refined oil has a longer shelf life. The purified composition is not afraid of exposure to sunlight or elevated ambient temperatures.It is intended for long-term storage in the refrigerator or at room temperature.

Unrefined oil at its nutritional value more useful than refined. It is enriched with nutrients and biologically active ingredients. Due to the valuable composition of this particular product is widely used in cosmetology and traditional medicine. In cooking, it is used only for the preparation of cold dishes.

Use of unrefined sunflower oil when consumed inside:

• restoration of the functioning of the central nervous system, improvement of liver function and digestion;
• immunity increase due to antioxidants, vitamins, mineral components and other beneficial substances contained in crude oil;
• beneficial effects on brain cells and preventing the development of atherosclerosis;
• restoration of reproductive function;
• improving the elasticity of blood vessels and joint mobility;
• cleansing the liver of toxins and other harmful substances;
• improvement of metabolic processes;
• normalization of the endocrine system;
• improving the quality of the blood;
• stimulation of growth hormone production, which is especially important for children and adolescents;
• normalization of the urogenital system in women and men.

In addition, the crude product is often used externally for facial and hair care at home. Masks based on this component can restore curls, make them more “alive”, smooth and silky. The use of oil for skin care helps to smooth wrinkles, tighten the oval face and nourish the skin. As a result of regular use, dry face is eliminated - it visually rejuvenates, gains health and freshness.

Refined oil in comparison with unrefined does not have such a benefit. However, it is an indispensable product for cooking fried, steamed or baked dishes. Refined vegetable oil is the best alternative to animal fats. With them, fried or baked food would be more harmful because of the high cholesterol content.

The use of purified oil is its resistance to heat treatment, the absence of smell and taste. All this is possible due to the removal of free fatty acids, flavoring substances and other components from the raw materials. But it is impossible to call such a product useful. Its harm exceeds the useful qualities. Below are the main disadvantages of the purified composition.

Chemical refining and heat treatment kill not only harmful substances in raw materials, but also useful ones. The result is an “empty” product devoid of phosphatides, carotene, proteins, and other components. The composition of natural oils is fundamentally different from those that have undergone a refining process. To produce the process of refining in production, using specialized chemicals - hexane and gasoline. According to the technology in the future, the product is cleared of these harmful substances. However, it is not possible to completely get rid of them.

The finished refined oil contains traces of hexane and gasoline. These substances are not excreted from the human body. Over time, they accumulate and lead to the appearance of tumors.

Refined and unrefined types of oils should be consumed inside no more than 2 tablespoons (including the content of the product in the dishes). For the therapeutic effect, it is recommended to drink 1 tablespoon of the composition in the morning before breakfast - this will allow in the shortest possible time to get rid of constipation.

To strengthen the gums and get rid of their bleeding, mouthwash with unrefined oil is recommended. To do this, dial it in your mouth and rinse for 10 minutes. This procedure should be repeated every morning for 14 days.

Unrefined oil can be used in home cosmetology. It is noteworthy that this tool is universal - it will suit owners of any skin type. Products made on the basis of unrefined oils are obtained “soft”, thanks to which they can be used even for sensitive skin and for the care of the eyelids and the area around the eyes.

In order for external application of the oil to be effective, it is important to listen to some recommendations.

• To care for dry and normal skin of the face and hands, unrefined oil should be added to the usual cream or mask. Such a composition will provide the removal of inflammation, smoothing wrinkles and soft skin. If the integument is prone to expanding the pores, then in this case it is best to use the refined product because of its lighter fraction.
• Heated unrefined oil can lubricate the lips, using it as a balm. The tool will promote the healing of microcracks, as well as protect the lips from various viruses.
• To strengthen the nail plate, it is recommended to make warm hand baths based on unrefined oils.
• To strengthen or restore hair, heated oil is applied from the roots to the ends of the strands and rubbed with soft massage movements into the scalp. The effect of such home procedures is also aimed at accelerating the growth of curls.
• Vegetable oils are used for massages. They saturate the skin with nutrients that penetrate deep into the skin by warming the integument and improving blood circulation in them.

On the shop windows there are a lot of containers with refined and unrefined sunflower oil from various manufacturers. To select the best quality of them, you should pay attention to several important factors.

• Shelf life of the goods. Watch the date of production of the product and its shelf life should always be, and in case of choosing vegetable oil, this item should not be missed. If the composition is close to the date of "delay", then it has a high peroxide value. This product has a bitter taste and acquires a specific smell. It should be noted that when oil is stored in inappropriate conditions (for example, being under natural or artificial lighting, a significant excess of air temperature), its shelf life is reduced.
• The purity of the oil. Before buying you need to give a visual assessment of the quality of the goods. Turbidity and sediment in the purified product is unacceptable. These signs speak about non-observance of conditions of its storage and low quality. From such a purchase is recommended to refuse. Sediment from unrefined oil is normal. The phospholipids contained in the crude product are precipitated. They are not synthesized by the body and come from food.
• Colour. The more transparent the refined oil, the deeper the purification is. Quality product will have a light color. The crude oil has a darker and more saturated color.

• Oil storage. Before buying a product, it is important to pay attention to where it is stored. It is best to choose the composition in a darkened display case or to get the container “from the depths”. When exposed to artificial light or when exposed to sunlight, the oil quickly loses its freshness and its beneficial properties, declared by the manufacturer.

In order for the oil to remain fresh as long as possible, it is important to follow a few recommendations for its storage.

Refined and unrefined product is best kept in the refrigerator or in the kitchen cupboard. The optimal storage temperature is from 5 to 20 degrees. Refined oil can be stored longer than unrefined. The latter is desirable to use within 3-4 weeks after opening. Refined version retains its properties for one and a half years.
