摘要: 超高压是一种有效的灭菌消毒技术。本研究通过鉴别设计(screening design)法对影响超高压杀菌效果的外界因子,如:压力、温度、保压时间、升压速度、卸压速度进行了关键因子考察与评价,试验结果表明:温度、压力、保压时间对灭活枯草芽孢杆菌影响显著,升压速度和卸压速度对灭活枯草芽孢杆菌影响不显著。

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
