What is cold-pressed oil?

Cold pressed oil is an indispensable product in the daily diet of healthy food. Its advantage lies in the fact that at the time of manufacturing all the vitamins and minerals that are present in the raw materials are preserved in it without the use of harmful impurities.

Definition

For cooking, there is a single technology of cold pressing, which ultimately gives the most delicious and healthy product. The output produces an ingredient of the highest quality, which is used both for cosmetic purposes and for food. Oil perfectly preserves a considerable amount of microelements, phospholipids, vitamins and acids. This is all achieved due to the fact that the structure does not disturb the production of biological substances.

The process of this pressing is to compress the necessary seed when the mass is heated to 45 degrees. It should be noted that with this technology, a smaller volume of raw materials is obtained, when compared with other manufacturing options.

What is good for health?

To date, unrefined cold-pressed oils have filled the shelves of supermarkets, but not everyone knows about their usefulness, and they prefer the customary many refueling.

In order to understand the need for the use of raw materials, it is necessary to understand the technological process of its production. The seeds of sunflower, flax and other ingredients are sent to a special press, after which they begin to squeeze out juices under high pressure. In this connection, the temperature of the charged mass increases.

It should be noted that even those who follow the regime of raw food, can safely use this product for food.

Thanks to this method of production, it retains all the complexes of vitamins inherent in a certain kind of oil. Also in it are 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 should be remembered that the present product at the time of production should not be amenable 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 foods. Proceeding from the aforesaid, at a choice it is necessary to be guided by presence of pleasantly expressed aroma, and also qualitative differing taste.

For example, olive oil of the first cold pressed, like products of the same manufacturing method, quickly deteriorate, this confirms their naturalness. They have a sediment and good turbidity. Using such refills in your diet, you can improve your health. At purchase it is necessary to be attentive, especially raw food, as some manufacturers can raise the temperature of manufacture to 90 ˚С. With this treatment, useful substances begin to disappear. A product that smells of burned or burnt oil does not meet all production standards.

Equipment

For the manufacture you need a screw auger, in the composition of which there must be a press for cold-pressed oil. Such devices are of different types. The main difference is the amount of processed raw materials, as well as the output capacity. For small businesses, machines that can process 6-10 tons of seeds per day are perfect. For larger firms, you need to choose devices with higher performance.

What is the difference between cold and hot pressing

Today, a huge number of oil manufacturers have appeared on the market, as such products are becoming increasingly popular. Prices for such goods are very different. It turns out that the mark "unrefined" 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, a 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 a different kind of fabrication, you can get a much more useful end result. This technology allows you to get the highest quality product, which, in turn, is more expensive, because up to 30% of oil remains in the cake.

Hot pressing reduces the amount of nutritious and beneficial properties. With perfect extraction, there should not be a sharp strong taste and aroma. Also, when ingested, the oil pleasantly envelops the throat and leaves a light taste after it.

Oil can be distinguished by the content of fatty acids. The smaller the number, the more valuable and expensive the product is. The complexity of manufacturing is that these fruits, like many others, begin to oxidize in air, and also when using a very high temperature. Therefore, in order to reduce this percentage, the production must occur as quickly as possible.

Cold pressing of olive oil is considered very useful and is most often done mechanically. In its composition, this oil can formally contain up to 1% of fatty acids, but such an indicator for serious companies is inappropriate. The most famous manufacturers tend to exclude or reduce the presence of this component altogether.

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.
