Abstract:

Concerns poor physical properties and sensory quality of the traditional rolling-process reconstituted tobacco require an improved method to get good reconstituted tobacco. In this study, we investigated the effects of natural fungi plant on reconstituted tobacco physical properties and sensory quality. The physical properties, conventional gas indexes and also the sensory quality of the new rolling-process reconstituted tobacco which was obtained by adding powder or colloidal solution (M20051) of the natural fungi plant (X20051) to the traditional rolling-process reconstituted tobacco were measured. The results showed, compared to the traditional rolling-process reconstituted tobacco, the water resistance increased from 0.63 min to 5.76 min and tensile strength also raised from 2.75 N/mm2 to 4.02 N/mm2, respectively, of the new rolling-process reconstituted tobacco. Meanwhile, the sensory quality score of the cigarette with 5% new rolling-process reconstituted tobacco was also increased 2.18 compared to others cigarette with traditional rolling-process reconstituted tobacco. At the same time, the tar and nicotine contained in the new rolling-process reconstituted tobacco were also decreased slightly. The strength toughness of the filaments contained in X20051 was the main reason to improve the physical properties of the new rolling-process reconstituted tobacco. The glutamic acid and aspartic acid contained in the X20051 and M20051 were the mainly substrate of the Maillard reaction and which could produce the aroma substances during the cigarette combustion, and this results to improvement of sensory quality of the reconstituted tobacco.
