Cold-pressed oil is an indispensable product in the daily diet of a healthy diet. Its benefit lies in the fact that at the time of manufacture it retains all the vitamins and minerals that are present in the raw material without the use of harmful impurities.
Definition
For cooking, there is a single technology of cold pressing, which in the end gives the most delicious and healthy product. The result is a superior quality ingredient that is used both for cosmetic purposes and in food. The oil perfectly retains a considerable amount of trace elements, phospholipids, vitamins and acids. This is all achieved due to the fact that the production does not violate the structure of biological substances.
The process of such extraction consists in pressing the necessary seed when heating the mass to 45 degrees. It should be noted that with this technology, a smaller amount of raw materials is obtained, when compared with other manufacturing options.
What is good for health?
To date, unrefined cold-pressed oils have filled supermarket shelves, but not everyone knows about their usefulness, and they prefer the usual gas station to many.
In order to understand the need for raw materials, you need to understand the manufacturing process. Sunflower seeds, flax and other ingredients are sent to a special press, after which juices begin to be squeezed out of them under high pressure. In this regard, the temperature of the refueling mass rises.
It should be noted that even those who observe the regime of raw food diet can safely use this product for food.
Thanks to this manufacturing method, it retains all the complexes of vitamins inherent in a certain type of oil. It also contains amino acids and natural vegetable fats, which are involved in the formation of cell membranes, and they, in turn, are responsible for the normalization of metabolism.
How to choose
It must be remembered that the real product at the time of production should not succumb to chemical treatment, as well as the introduction of a variety of preservatives. The use of such supplements is very important for those who seek to improve their health and eat natural food. Based on the foregoing, the choice must be guided by the presence of a pleasantly expressed aroma, as well as a qualitative different taste.
For example, olive oil of the first cold pressing, as well as products of the same manufacturing method, deteriorate quickly enough, this confirms their naturalness. They have sediment and good turbidity. Using such refills in your diet, you can improve your health. When buying, you need to be careful, especially raw foodists, as some manufacturers can increase the temperature of manufacture to 90 Β° C. With this treatment, beneficial substances begin to disappear. A product that smells of burnt or burnt oil does not meet all production standards.
Equipment
For manufacturing, you need a screw oil mill, which should include a press for cold-pressed oil. Such devices are of various types. The main difference is the amount of processed raw materials, as well as the power output. For small enterprises, machines that process 6-10 tons of seeds per day are perfect. For larger companies, you need to choose devices with higher performance.
What is the difference between cold and hot pressed
Today, a huge number of oil manufacturers have appeared on the market, as such products are becoming increasingly popular. Prices for such products vary widely. It turns out that the mark βunrefinedβ does not always say that the oil is made in compliance with all requirements and will bring maximum health benefits. The processes can be divided into hot and cold pressing. In the production of the first type, high temperature is used, which, in turn, speeds up the production of the product. With this treatment, much more oil comes out than with the second option. Using another type of manufacturing, you can get a much more useful final result. This technology allows you to get the highest quality product, which, in turn, is more expensive, because up to 30% of the oil remains in the oilcake.
Hot pressing reduces the amount of nutritional and beneficial properties. With perfect production, there should not be a sharp strong taste and aroma. Also, when swallowed, the oil pleasantly envelops the throat and leaves a light taste. In order to choose the right cold-pressed oil, you should pay attention to the inscription - Extra Virgin. The difference in quality and usefulness for the body is great, so the decision is left to each person.
Olive
Production begins immediately after the harvest, that is, the dates fall at the end of November - beginning of December. Berries need to be cleaned of twigs and leaves, and then thoroughly washed. Further, the fruits are ground on stone millstones, and the resulting paste is well mixed and heated to a temperature of no more than 27 degrees. Then a traditional press or centrifuge is used, so that the extra virgin olive oil is cold pressed.
Oil can be distinguished by the content of fatty acids. The smaller their number, the product is considered better and more expensive. The complexity of manufacturing is that these fruits, like many others, begin to oxidize in air, as well as when using very high temperature. Therefore, in order to reduce this percentage, manufacturing should occur as quickly as possible.
Cold pressed olive oil is considered very useful and is most often produced mechanically. In its composition, such an oil can formally contain up to 1% fatty acids, but such an indicator for serious companies is inappropriate. The most famous manufacturers tend to generally eliminate or reduce the presence of this component.
This factor is due to the fact that the reaction begins to occur immediately at the time of removal of the fruit. The closer the press is, the better the final product.
Sunflower
To obtain oil, you must use fresh seeds. Quality, first of all, will depend on the state of the source material. Seeds should be oilseeds with a moisture content of not more than 6%, otherwise the resulting product will be too watery. A significant role is played by the degree of maturation, as well as the heat and light received during the growing process.
Cold-pressed sunflower oil is the most useful; all trace elements necessary for the body are stored in it.
In its composition, it has the following vitamins:
- A (improves vision well);
- D (provides the exchange and assimilation of calcium);
- E (helps to maintain youth, health, and is also considered a natural antioxidant);

Is it possible to fry?
Many people wonder whether it is allowed to cook using cold-pressed butter. Such an action, of course, is permissible, but at this moment the ingredient loses its unique taste and aroma, as well as positive properties. It is too useful in its raw form for such a utilitarian use. Its bright taste is not combined with all products, for example, you should not cook fish on it at all. Good quality oils that have a neutral taste are perfect for frying. This product undergoes special processing and is suitable for such purposes, without losing all its beneficial properties.
Recommendations
In order not to be disappointed after acquiring the selected refueling, several factors must be taken into account. At the time of purchase, you need to pay attention not only to the expiration date, which is very small, but also to the packaging. Since the product is afraid of light and oxidizes quickly, it should be in a dark-colored glass container and be hermetically sealed. Another important point is his storage at home, subject to the same conditions. After the expiration date, it is better not to use it in food, because it can affect the state of health.
Cold-pressed oil is much more expensive than products that have undergone chemical cleaning and processing, and therefore you can be sure that manufacturers monitor the quality of their goods and control the presence of fakes.
