How Edible Vegetable Oil Is Made?

Edible oil always plays an important role in our lives. The question about the choice of edible oil will naturally lead to hot discussion and concern. There are generally two methods for processing edible vegetable oils: pressing and extracting. The pressing method is a method of pressing oil from oilseeds by mechanical pressing. It originated from the traditional oil-making method of the workshop. Nowadays, the pressing method is a large-scale, industrialized operation, but the basic principle has not changed. The solvent extraction method is a method of extracting oil from oil by an internationally recognized and common food-grade solvent using the extraction principle of food engineering. This extraction is essentially a physical dissolution process in which no chemical reaction of oils and solvents occurs. From the development history of the world edible oil preparation process, the extracting oil production process is an internationally recognized advanced production process, and most of the vegetable oil is now produced by the solvent extraction method.

But these are called "crude oils". According to the national standard of edible oil in China, "crude oil" must be refined to remove harmful ingredients and some "impurities" and become a qualified product oil in accordance with the national standard before it can be eaten. Whether it is pressing or solvent extraction, it only solves the production of “crude oil”, which is inedible at first, and the “crude oil” into refined oil must undergo a refining process. The purpose of edible oil refining equipment is to refine crude oil, usually referring to the refinement of crude oil. The existence of impurities in crude oil not only affects the edible value and safe storage of oils and fats, but also brings difficulties to deep processing. However, the purpose of refining is not to remove all impurities in oils, but to remove harmful impurities. According to different requirements and uses, unnecessary and harmful impurities can be removed from oils and fats, so as to meet the requirements. The refined oil with a certain quality standard is the purpose of oil refining.

The edible oil products on the market are safe as long as they meet the quality standards and hygienic standards of edible oil. Consumers can rest assured that they are edible.
