[Method]The prepared liquid egg white was subjected to DPCD treatment at 10 MPa,20 MPa and 30 MPa respectively at 30 ℃,the microorganism amount,pH value,dissolubility and surface sulfhydryl were detected after adjusted to 4 ℃. [Result]The results showed that the longer the sterilization time,the more obvious of the sterilization effect at 10 MPa. There was no aerobe was detected at the rest conditions. [Conclusion]The functionial properties and physicochemical properties of liquid egg white were effected by DPCD treatment.展开更多
