Mathematical model of mechanical oil expression from oilseeds
Abstract. Consequently, it is likely that the rate determining step in the oil expression process is the transport of oil across the cell walls in the seed kernel. This is due in part, presumably, to the low porosity and small size of the pores on the cell wall resulting in a high resistance to fluid flow.
