Soybean oil refining effectively removes impurities and improves oxidation stability through processes such as degumming, deacidification, decolorization, and deodorization. It is a key technology to ensure that the product meets food grade and industrial application standards. With the steady growth in demand for soybean oil in various industries, the market for soybean oil and its refined products is expected to grow further.
Soybean oil has a high content of gum, and the hydration degumming method is usually used to remove the gum in crude soybean oil under the action of phosphoric acid.
In a batch soybean oil refinery, free fatty acids are neutralized with alkali and then converted into soapstock, while other impurities are removed by adsorption.
Physical refining is an option for removing free fatty acids in semi-continuous and fully continuous soybean oil refineries. Physical refining uses steam to carry out the free fatty acids, which are then collected in storage tanks.
The bleaching process uses bleaching clay to absorb unwanted pigments in soybean oil, making the color of the soybean oil lighter.
The deodorization process is to remove odors through steam distillation. In this process, odor compounds are removed by injecting steam into the heated oil under high vacuum pressure.
