| 摘 要： | 本实验以市售灭菌乳为研究对象,应用Weibull模型通过对食品非感官指标的分析,预测食品的货架期。灭菌乳分别在25、30、35、40℃环境下恒温储藏,并定期随机抽样进行感官检验和测定酸度、细菌总数。应用Weibull Hazard Analysis(WHA)方法分析非感官实验数据来预测样品货架期,并与采用寿命加速方法ASLT和文献WHA方法得到的预测结果进行了比较。

| Abstract: | This paper applied accelerated shelf-life test (ASLT) and sensory hazard analysis to the determination of shelf-life, with UHT(ultra heat treated) milk as experimental object. Moreover it discussed the feasibility of applying physicochemical Weibull hazard analysis to the determination of shelf-life as well as the reliability analysis of commercial shelf-life. UHT milk, with commercial shelf-life of 45 days, was divided into four experimental groups, and stored at 25 ℃, 30 ℃, 35 ℃ and 40 ℃ respectively. The sensory, physicochemical and bacterial testing was carried out at stated intervals. |
