Abstract: The Central Composite Design was used to investigate the sterilizing regularity of chlorine dioxide on saprophyticyeast on the surface of the apples for juice-squeezed. Through regression analysis, a mathematic model was established todescribe the relationship between sterilizing result and its main influential factors, such as concentration, sterilizing time, pH ofsterilizing liquid and sterilizing temperature. It was verified that this mathematic model could be used to describe the sterilizingregularity of chlorine dioxide on the saprophytic yeast and to forecast the sterilizing efficacy in a relatively accurate manner.

Key words: chlorine dioxidesaprophytic, saprophytic yeast, sterilization, mathematic model, Central Composite Design
