This paper presents some results associated with physicochemical changes of fresh duck eggs after being preserved by chitosan membranes at different concentrations. Chitosan coating at the concentration of 1.5% worked best for preserving fresh duck eggs at normal temperature. The number of total Coliforms after 30 days was 30 Coliforms/100 g sample. There was no detection of the existence of Salmonella in eggs of experimental samples.
