摘要: 研究鱼肉肠杀菌工艺处理压力、保压时间以及协同温度对微生物存活量的影响,并采用正交试验优化鱼肉肠的杀菌工艺条件。结果表明,在各因素中,处理压力是最重要的影响因素,温度次之,最后是保压时间。通过数据分析得出杀菌的最优工艺条件为处理压力400MPa、保压时间5min、协同温度30℃,在此条件下处理,鱼肉肠的菌落总数减少了97.25%,大肠菌群、霉菌和酵母菌致死率可达100%,致病菌在超高压处理前后均未检出。

Abstract: The effects of pressure, dwell time and temperature on microbial survival in fish sausage after ultra high pressure (UHP) sterilization were studied, and the sterilization conditions were optimized using orthogonal array design. Pressure was the most important affecting factor, followed by temperature; dwell time had the weakest effect. The optimal sterilization conditions were treatment pressure of 400 MPa, pressure-holding time of 5 min and treatment temperature of 30 ℃. Total bacterial count in fish sausage was reduced by 97.25% after UHP sterilization under these conditions, and 100% E. coli, mold and yeast were killed. No pathogenic bacteria were detected before and after UHP sterilization.

Key words: ultra high pressure, fish sausage, sterilization technology, orthogonal array design
