Soybean oil is also called soybean oil. As the name implies, it is made by squeezing soybeans. Mainly produced in Northeast China, North China, East China and Central South China.
Compared with other oil raw materials, the oil content of soybean is low, only16% ~ 24%. In order to achieve the maximum benefit, manufacturers generally use leaching method to obtain most of the oil in soybeans during the process of squeezing soybeans. Therefore, the soybean oil that can be seen in the market is mostly refined oil produced by leaching method.
The longest shelf life of soybean oil is only one year. The better the quality, the lighter the color, which is light yellow, clear and transparent. And there is no sediment, no fishy smell of beans, and high-quality soybean oil with a temperature below zero degrees Celsius will have oil crystals.

Leaching oil-production process:? The leaching method is made by fully soaking the oil and fat raw materials in solvent oil (No.6 light gasoline) and then extracting them at high temperature, and then processing them through the "six-removal" process (i.e. degreasing, degumming, dehydration, decoloration, deodorization and deacidification). The biggest feature is high oil yield and low production cost, which is one of the reasons why the price of soybean salad oil is generally lower than that of pressed oil.
In the process of leaching, the residue in edible oil is inevitable. According to national standards, even qualified leached soybean oil is allowed to contain 10 mg of solvent residue per kilogram.
