Abstract: In order to study the quality change of paper-making tobacco during storage, two kinds of domestic paper-making reconstituted tobacco products were selected to analyze the changes in color appearance, aroma components and sensory quality in a one-year storage period. The ΔE values of the two kinds of paper-making tobacco products were calculated by L*, a* and b* values measured by an X- rite Color i5 colorimeter. Meanwhile, the change of their colors was observed and analyzed. The aroma components of the two papermaking tobacco products were determined by Simultaneous Distillation Extraction methods, and were analyzed comprehensively in terms of six categories such as aldehydes and ketones, and alcohols. Meanwhile, the scoring method developed by Guangdong Tobacco Industry Co. was chosen to evaluate the sensory smoking qualities of all samples. The results showed that: (1) the appearance, colors and ΔE values of both the reconstituted tobacco products dramatically increased with a prolonged storage, despite the contents of aroma components displayed a complicated‘up-down-up-down’tendency, the sensory smoking quality achieved the highest level at the middle stage of storage, followed by a notable reduction at the later stage; (2) based on analysis of aroma components and sensory smoking quality, reconstituted tobacco with a 2-8 month storage period had a better overall quality. Thus, the present investigation revealed that a suitable storage period is beneficial for stabilizing or enhancing the sensory smoking quality of cigarette products.
