This document specifies a method using automated Randall extraction for the determination of the hexane extract (or light petroleum extract), called the "oil content", of oilseeds used as industrial raw materials.
The procedure for sunflower seed is different from those for others seeds as it includes an additional moisture content determination after the seed has been ground to prepare the test sample.
If required, the pure seeds and the impurities can be analysed separately. In the case of groundnuts, the pure seeds, the total fines, the non-oleaginous impurities and the oleaginous impurities can be analysed separately
