摘要
目的:了解造纸法再造烟叶在贮藏过程中内在化学成分、抗张强度和热失重特性随时间变化的规律,获得再造烟叶最佳使用时间。方法:对不同贮藏时间下3种造纸法再造烟叶(JS-A、JS-B和JS-C)的常规化学成分、抗张强度和热失重特性进行分析比较。结果:JS-A和JS-B样品的总植物碱、总糖、总氮和水分含量随贮藏时间增加变化显著,JS-C样品的总植物碱和总氮含量变化不显著。贮藏时间对3种再造烟叶的纵向抗张强度影响显著,均在180 d时出现最大值。3种样品的第二阶段失重率和归一化热焓值随贮藏时间的增加有显著变化,均在360 d时达到最大值。结论:3种再造烟叶适宜的贮藏时间为180~360 d。
Objective:To investigate the effect of storage time on the quality of paper-making reconstituted tobacco,the change of internal chemical components,tensile strength and thermogravimetric properties of paper-making reconstituted tobacco were studied.Methods:Continuous flow analyzer,tensile strength tester and thermogravimetric analyzer were introduced to analyze three kinds of paper-making reconstituted tobacco with different storage time.Results:The contents of total alkaloids,total sugar,total nitrogen and moisture of JS-A and JS-B samples changed significantly with the increase of storage time.While the content of total alkaloids and total nitrogen of JS-C samples didn t change much.Besides,storage time had a significant effect on the longitudinal tensile strength of the three kinds of reconstituted tobacco leaves.Further,for all of the samples,the maximum values appeared at 180 days.The weight loss rate and normalized enthalpy of the three samples in the second stage changed significantly with the increase of storage time,and reached the maximum value at 360 days.Conclusion:The suitable storage time of three kinds of reconstituted tobacco leaves was between 180 and 360 days.
