The functional properties of egg shell membrane hydrolysate by Bacillus licheniformis(EESMH) and NaOH-ethanol(AESMH) as a food material were investigated.. The yield of egg shell membrane hydrolysate was about 15% by Bacillus licheniformis, whereas that was 70% by NaOH-ethanol. Histidine content was higher in EESMH (18.69%) than in AESMH (2.56%). Both EESMH and AESMH showed high protein solubility (>95%). Emulsi-fying activity and stability of EESMH were higher than those of AESMH. foaming capacity and stability of AESMH were 2 times higher than those of EESMH in the pH ranges from 2 to 12. The AESMH had antioxidative activity whereas EESMH had not. Therefore, both AESMH and EESMH can be used for industrial food materials from the results of functional properties.
