A process for the producing edible protein-containing meal for human and
animal consumption and high quality food grade oils from oil seed using
iodotrifluoromathane as the solvent is shown. The meal has a
significantly improved level of dietary available (absorbable) protein.
The process involves the preparation of protein isolates by a procedure
which is conducted at room temperature, thus decreases protein
degradation and denaturing which is caused by elevated temperatures. The
process also provides for extraction of substantially all oils and fats,
which interfere with the formation of the protein micelle, from the
protein meal providing a cleaner, purer product with high levels of
absorbable protein. Such protein isolates can then be used as such or
added to formulated foods in order to increase the total protein content
of that food. The protein produced and the oils recovered have
compositions which are also unique and unobtainable by prior processing
methods.
