Soybean oil pretreatment pressing process vs soybean oil pretreatment puffing solvent process

Soybean oil comes from soybean seeds and is the most productive oil in the world. There are many kinds of soybean oil, which can be divided into pressing soybean oil and leaching soybean oil according to the processing technology.

The processing technology of pressing oil is "physical pressing method", while the processing technology of leaching oil is "chemical leaching method".

The production process of physical pressing method requires that raw materials should be carefully selected. The oil is broken, steamed and fried after removing impurities and stones, and extruded to separate the oil from the oil. The fried seeds are added in the process of pressing, and pressed by the press, and made of high-tech natural filtration and purification technology. It is a pure natural green food produced by combining modern technology with traditional technology. It is rich in vitamin E and has a long shelf life without any additives, solvent residue and soap content.

Leaching rule by organic solvent extraction method, by "six light gasoline" with the oil (commonly known as "6 # solvent oil") after the combination of the organic solvent for extraction, therefore, are toxic to the human body is ethane is difficult to completely remove organic matter, such as only after scouring to very strict standards, to eat, but in high temperature scouring, Unavoidably can make some vitamin nutrient material suffers loss.

At present, more than 90% of soybean oil in the market is processed by leaching method, but with the increase of health awareness, people are more inclined to choose physical pressing, nutrient-rich edible oil, so the process of pressing soybean oil is gradually replacing the leaching process, but in general, no matter now or in the future, Extraction of soybean oil by leaching is still the method adopted by most manufacturers.（Related reading：Soybean oil processing machine）
