Oil extraction from soybeans is a process that involves several steps. The main steps are:
1. Cleaning of soybeans: In the initial stages, the soybeans will be cleaned so as to remove impurities.
2. Crushing of the soybeans: After cleaning, the next step is crushing process. The soybeans are cracked, adjusted for moisture content, heated and rolled into flakes.
3. Softening process: The purpose of softening is to adjust the moisture and temperature of oil seeds, and make them soft and elastic.
4. Soybeans rolling process: The aim of rolling is to destroy the cell structure of oil seeds, and increase the surface area for oil extraction.
5. Soybeans extruding process: Extruding is a kind of high temperature and short time treatment, which can passivate the activity of anti-nutritional factors and improve the flavor of flakes.
6. Solvent extraction process: The solvent extraction process uses hexane or other solvents to wash the soybean oil from the prepared soybean flakes. The solvent is then removed from both the flakes and the oil by distillation.
7. Refining the extracted oil: The crude oil obtained from solvent extraction needs further processing to make it edible. The soybean oil refining process includes degumming, neutralizing, bleaching and deodorizing.
I hope this helps you understand how oil is extracted from soybeans.
