摘要：Protein isolates having a high protein content and low residual fat content areprovided in substantially non-denatured form by extracting an oil seed meal having asignificant fat content, particularly canola meal, with an aqueous food grade salt solutionto cause solubilization of protein and fat in the oil seed meal and form an aqueousprotein solution. Fat is removed from the aqueous protein solution by chilling theaqueous protein solution and removing the fat which separates. The protein
concentration of the defatted protein solution is increased while the ionic strength ismaintained substantially constant. A further fat removal operation may be carried out onthe concentrated protein solution followed by dilution to an ionic strength below about0.2 to cause the formation of discrete protein particles in the aqueous phase in the formof protein micelles. These protein micelles are settled to form a mass of aggregatedprotein isolate in the form of an amorphous, sticky gelatinous, gluten-like proteinmicellar mass, which is separated from the supernatant and dried to a proteinaceouspowder.
