The processing of soya beans produces a degummed oil, raw lecithin and a meal and, depending on the processing route followed, the meal can either be rich or low in protein (Figure 1). Cleaning is carried-out to remove any dirt, trash and loose hulls and the beans may dried or not depending on their moisture content and whether a high or low protein meal is desired. With the production of high protein meal the beans are dried to about ten percent moisture, this ensures proper cracking and dehulling.
