Abstract:  High hydrostatic pressure (HHP) is an effective kind of cool technique of inactivation. Screening design was usedfor estimating the sterilized effects of external factors in high hydrostatic pressure in this study, with respect to the variablespressure, temperature, pressure holding time, ramp rate and depressurization rate. Result showed that the pressure, temperatureand pressure holding time were believed to be the major factors for high hydrostatic pressure inactivation and the ramp rate anddepressurization rate were not.

Key words: high hydrostatic pressure (HHP), bacillus subtilis, screening design, external factor
