利用热时模型研究贮存时间和环境温度对卷烟感官质量的影响

Effects of Storing Time and Temperature on Sensory Quality of Cigarette with Thermal-time Model

针对国内6个城市储存的7种牌号卷烟,分析了贮存时间、贮存环境温度对感官质量的影响。结果表明:①卷烟贮存半年内感官质量变化很小,卷烟样品在广州贮存7个季度后感官质量开始有较明显改变,在兰州和长春贮存2年感官质量有较小的变化。卷烟贮存在南方比北方感官质量变化速度快,贮存环境温度越高,卷烟感官质量变化越快;②方差分析结果表明不同贮存季度和不同贮存地区卷烟的感官质量变化均达到了极显著水平。

Taking cigarettes of 7 brands stored in 6 cities as samples, the influences of ambient temperature on the sensory quality of stored cigarettes were investigated. The results showed that： 1） Sensory quality of the samples changed slightly in 6 months. The sensory quality change became obvious when the samples had been stored for longer than 7 quarters in Guangzhou; however, the sensory quality of samples stored in Lanzhou and Changchun for 2 years changed slightly. The sensory quality of samples changed faster in southern areas than in northern areas; so did in higher storing temperature than in lower temperature. 2） The results of variance analysis showed that the changes of sensory quality of cigarette samples stored in different cities for different periods all reached extremely significantly levels.
