The soybean is a
material system.
A soybean contains oil, protein, carbohydrates, fibre, moisture, minerals and naturally occurring minor components. The proportions and physical condition of those constituents determine what can be recovered and how the resulting ingredient streams behave.
For a processor, the objective is not merely to “remove oil”. It is to manage the transformation of the bean into stable, useful product streams while controlling the conditions that influence quality and suitability for the intended market.
