During solvent extraction of soybeans, the whole soybean
is cracked and heated to approximately 60 to 74°C,
then flaked and exposed to hexane solvent to extract the
oil [3,4]. After the hexane is volatilized, SBM is heated to
destroy anti-trypsin factors. For production of expanded
SBM, the soybeans are heated by friction during passage
through the expander; steam injection may also be
