The objective of the paper was to improve rapeseed protein functionalities through limited hydrolysis with neutral protease.The results showed that protein functionalities of rapeseed protein were improved effectively.Solubility of DH 10 rapeseed protein was up to 57.11% at pH 7.0.Emulsion of DH 2.0 hydrolysate was at its best within the range of measuring pH,increased by 40% more than that of the rapeseed protein.The foaming of DH 4.0 hydrolysate maximized to 162.5%.The oil-holding capacity and water-holding capacity of DH 2.0 hydrolyzate were at their best,multiplied by 2.6 times and 1.9 times respectively.
