天然菌类植物在辊压法再造烟叶中的应用研究

Research on Improving Quality of Rolling-process Reconstitution Tobacco

为了解决辊压法再造烟叶物理性能和感官质量差的问题,以高香气、低木质素的天然菌类(X20051)为原料,将其粉碎成粉末和制得的菌类胶体溶液(M20051)添加到辊压法再造烟叶中,生产出新型辊压法再造烟叶,并对2种再造烟叶的物理性能和感官质量进行了对比,结果表明:添加天然菌类植物的再造烟叶耐水性从0.63min提高到5.76min;抗张强度从2.75N/mm2提高到4.02N/mm2,感官质量提高了2.42分;将新型再造烟叶和传统再造烟叶按照5%的比例添加到某品牌卷烟中进行对比评吸,卷烟感官质量提高了2.18分,焦油量和烟气烟碱量略有降低。M20051的丝状体韧性较强,是提高新型辊压法再造烟叶物理性能的主要原因;X20051和M20051中含有较多的谷氨酸、天门冬氨酸是Maillard反应的主要前提物质,在卷烟燃烧过程中形成致香物质,是再造烟叶感官质量提高的主要原因。

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 rain 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 by 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 main 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.
