A new protein-based water soluble compound OPI-MPEG,has been synthesized using hydrophilic polyethylene glycol monomethyl ether(MPEG) substitutions.The success of synthesis was confirmed by FT-IR and 1HNMR spectroscopy.The morphology of OPI-MPEG has been investigated by using tapping mode atomic force microscopy(TP-AFM),the results show that the largest size of OPI-MPEG is about 10.5nm,the least size is about 2.5nm,and the average size is about 5.0 nm.OPI-MPEG had good solubility in water and other organic solvent.Foaming ability and stability has increased to 78.3% and 68.0%,respectively.Emulsifying and emulsion stability has increased to 60.8% and 55.3%,respectively.
