覆膜铁罐装橘子罐头货架期预测研究

Study on the shelf-life prediction of canned orange with laminated steel can

该文研究了不同贮存温度与时间下覆膜铁罐装橘子罐头的空罐质量、食品安全、内容物质量和感官变化情况,并以pH、固形物含量、褐变度、柠檬酸含量、感官评价为指标,采用SPSS软件进行因子分析,建立了基于Q_(10)模型的橘子罐头货架期模型。结果表明,在常温(25℃)、37℃、55℃贮存环境下,橘子罐头的空罐质量良好,食品安全达标,影响货架期的主要因素为内容物质量和感官。橘子罐头的pH、固形物、柠檬酸及感官评价分值随贮存时间的延长而降低,褐变度随着贮存时间的延长而升高,且贮存温度越高变化越快。该研究所建模型适用于橘子罐头货架期的预测。

The canned orange with laminated steel was studied on the quality of empty can,food safety,content,and sensory under different storage temperatures and times.The indicators contained pH,solid content,browning degree,citric acid content,and sensory evaluation,which were analyzed by SPSS statistics.The Q_(10) model was applied to establish a shelf-life prediction model for canned oranges.It was indicated that under the storage environment of room temperature(25℃),37℃,and 55℃,the empty can of canned oranges was of good quality,besides the food safety of which met standards.Thus,the main factors affecting the shelf-life were the content quality and sensory.As the results showed that pH,solid content,citric acid content,and sensory evaluation decreased with prolonged storage time and dropped promptly with increasing storage temperature while the browning degree increased with prolonged storage time.The model is suitable for the shelf-life prediction of canned oranges.
