The functional properties of defatted wheat germ powder（containing protein 27.58%） prepared by supercritical CO2 extraction, including emulsion, emulsion stability, foaming and bubbling stability, oil sorption capacity, water holding capacity were studied in this paper. The results were as follow： the defatted wheat germ powder had the largest emulsion at the protein concentration of 5% and pH 9; it had the highest oil sorption capacity at 70 ℃; it had the worst foaming capacity at pH 7; it had the best water holding cap...
