Abstract: Under different temperatures,pressures and alcohol concentrations,the changes in salt content,egg yolk index,oil content,and egg white pH value and viscosity of salted duck eggs were investigated. In order to optimize the production process to shorten its cycle,orthogonal test was designed. The results showed that salting can be finished in five days under the conditions of 0.13 MPa,35 ℃ and alcohol concentration 5%.

Key words: salted duck egg, salting, oil content, egg yolk index, egg white viscosity
