中文摘要: 以佛跳墙罐头产品为研究对象,采用感官评价、理化指标分析和 Weibull 危害分析方法,来预估佛跳墙的货架 寿命。结果表明:佛跳墙在贮藏过程中理化指标(pH 值、TBA、挥发性盐基氮、总菌落数、致病菌落数)未发生明显变化,但 产品在 30、35、40 ℃下分别贮藏 143、85、58 d,感官评价不再符合出售要求;危害分析法预测得佛跳墙罐头产品在 25 ℃ 下贮藏的货架期为 296 d。

Abstract:In order to predict the shelf life, the canned Fotiaoqiang was measured by sensory, physical and chemical properties analysis and Weibull hazard analysis. The results showed that: the canned could preserved at 30 ℃ for 143 d, 35 ℃ for 85 d and 40 ℃ for 58 d respectively, during storage the physical and chemical in- dicators of canned(pH value, TBA, TVB-N, total bacterial count, pathogenic bacteria count. ) did not change significantly, but the sensory evaluation no longer meets the requirements for sale. According the result of weibull hazard analysis, the shelf life was 296 d at 25 ℃.
