温度对烟用香精折光指数的影响
Effects of temperature on tobacco flavor refraction index
-
摘要: 为探讨不同温度对烟用香精折光指数的影响,对8个不同样品烟用香精进行实验:在10~30℃范围内改变烟用香精的测试温度,测定其相应的折光指数,对数据进行分析处理,得出温度与折光指数的线性方程,并将实测值与换算值进行比较.结果表明,温度与烟用香精的折光指数呈显著的线性负相关,不同样品折光指数受温度的影响不同,差别较大,相对密度<1的香精,其折光指数受温度影响的幅度较相对密度>1的香精大.Abstract: To investigate the effects of different temperature on tobacco flavor refraction index,8 different samples were tested.Temperature was changed from 10℃ to 30℃ when the refraction indexes were determined.The linear equations came out from data processing and analysis,at same time the measured value were compared with conversion value.The results showed that temperature had obvious linear negative correlation with refractive index.The effects of temperature on refractive index were much different for different samples.The effects on flavor with relative density lower than 1 were larger than that of flavor with relative density higher than 1.
