A process of aqueous protein extraction from Brassicaceae oilseed meal, such as canola, commercial canola meal or yellow mustard, to obtain a napin-rich protein extract, a cruciferin-rich protein extract, and a low-protein residue. The process comprising the steps of performing aqueous extraction of the Brassicaceae oilseed meal at a pH of from about 2.5 to about 5.0 to obtain a soluble napin-rich protein extract and a cruciferin-rich residue followed by performing aqueous extraction of the cruciferin-rich residue to obtain a soluble cruciferin-rich protein extract and a low-protein residue. The cruciferin-rich residue may be treated with cell wall degrading enzymes to obtain a cruciferin-rich fraction The cruciferin-rich protein products may be substantially free of napin protein and may be useful as a non-allergenic food product for human consumption.

[object Object]

The invention provides a process for producing polysaccharide gum comprising extracting a plant material with an aqueous solvent to produce a polysaccharide gum-containing extract; contacting the extract with at least one proteolytic enzyme to at least partially digest proteins in the extract; adding an organic solvent to the extract to precipitate the polysaccharide gum; and collecting the precipitated polysaccharide gum.
