摘要: 对软包装主食罐头的杀菌工艺进行研究,分析在不同杀菌温度和时间条件下食品中心温度及F值的变化,确定最佳杀菌方式为双峰高温杀菌,杀菌参数为80℃、5min,110℃、5min,121℃、12min,125℃、(30+30)s,峰底113℃,该杀菌工艺能够有效降低软包装主食罐头的杀菌强度,杀菌后的产品大大降低了因高温产生的后熟蒸馏味,大幅延长了保质期,最终产品品质显著提高。

Abstract: This study was undertaken to investigate the sterilization of retort pouches containing staple foods. Variations in central temperature and F value were analyzed under various conditions of sterilization temperature and time. The optimal sterilization process was double peak high temperature sterilization at 80 ℃ for 5 min, 110 ℃ for 5 min, 121 ℃ for 12 min and 125 ℃ for 30 s + 30 s with a peak base temperature of 113 ℃. Under these conditions, the sterilization intensity of retort pouches was attenuated effectively. Moreover, the distillation odor caused by high-temperature sterilization was reduced greatly, and the shelf life was markedly extended. As a result, the quality of staple foods could be obviously improved.

Key words: staple food in retort pouch, dual-peak sterilization, F value
