 Edible oil is an indispensable part in our daily life, it can provide some essential nutrients and nutrients for the human body. Each type of oil contains many kinds of fatty acids, among which linoleic acid, linolenic acid and arachidonic acid which cannot be synthesized by human body and they must be obtained from food. Therefore, these three fatty acids are also known as "essential fatty acids".

When we go to the supermarket to buy oil, we often find such a term, "pressed oil" or "extracted oil", then which of the two oils is healthier? There are two methods of processing edible vegetable oil: pressing and leaching. Press method is the physical press method to extract oil from oilseeds. Leaching is a method of extracting oil from oil with edible solvent based on chemical principle.

No matter whether it is the pressing method or the oil obtained by the extracting method, it cannot be eaten directly. It is called crude oil. The crude contains various impurities, including those in the raw material, which are produced during the extraction or leaching process. Some impurities are extremely harmful to the human body, the crude oil is further processed (i.e. refined) to remove impurities and become product oil that can be eaten.

The product oil, which conform to the national standard, can be eaten safely, no matter what kind of technology they produce. The idea that oil produced by extracting is less pure than that produced by pressing is highly inaccurate. The quality of edible oil is measured not by the production process, but by the national index system for various types of edible oil.
