The present invention provides a method for processing defatted oil seeds, comprising
the steps of: (a) solubilizing at least a portion of the protein contained in the
oil seeds to produce suspended residual solids and a first solution comprising
protein, phenolic-protein complexes, and free phenolic compounds; (b) separating
at least a portion of the free phenolic compounds from the first solution and recovering
a free phenolic reduced solution; and (c) treating the free phenolic reduced solution
to precipitate at least a portion of the protein as a precipitated protein isolate
and recovering a treated solution containing a soluble protein isolate. Novel protein
products are also disclosed. Food and drink products containing the novel protein
products are also disclosed.
