摘　　要：为分析新型制造工艺的加热卷烟基片,采用扫描电子显微镜、热重和热重-傅里叶红外光谱-气相色谱/质谱(TG-FTIR-GC/MS)联用技术比较了加热卷烟再造烟叶的结构以及热行为。结果表明:(1)3种新型工艺加热卷烟再造烟叶结构紧密程度为新型辊压法>新型涂布造纸法>造纸稠浆复合法。(2)新型辊压法、新型涂布造纸法和造纸稠浆复合法再造烟叶均具有4个失重阶段,起始分解温度分别为43.12、143.69和43.44℃,最大失重分别发生在新型辊压法和新型涂布造纸法的第二失重阶段以及造纸稠浆复合法再造烟叶的第三失重阶段。(3)不同再造烟叶分别裂解出少量特征香味成分,例如,新型辊压法的异丁香酚、新型涂布造纸法的香兰素和造纸稠浆复合法的2,3-二氢-3,5-二羟基-6-甲基-4H-吡喃-4-酮(DDMP)。3种新型工艺再造烟叶热解过程的主要逸出物为甘油、烟碱和少量特征香味成分,且3种再造烟叶均适合作为烟芯材料应用于加热卷烟。To analyze the reconstituted tobacco sheet materials produced by three new processes for heated tobacco products,the structures and thermal behavior of the reconstituted tobacco were compared using scanning electron microscopy,thermogravimetry,and thermogravimetry-Fourier transform infrared spectrometry-gas chromatography/mass spectrometry.The results showed that:1)For structural compactness,the three new reconstituted tobacco materials were ranked as:new rolling process>new coating papermaking process>papermaking-slurry composite process.2)The reconstituted tobacco produced by the new rolling process,the new coating papermaking process and the papermaking-slurry composite process all had four weight loss stages with initial distillation temperatures of 43.12,143.69 and 43.44℃,respectively.The maximum weight loss occurred in the second weight loss stage of the reconstituted tobacco produced by the new rolling process and the new coating papermaking process and the third weight loss stage of the reconstituted tobacco produced by the papermaking-slurry composite process.3)Small amounts of characteristic aroma components were released from the different reconstituted tobacco samples by the detection method,such as isoeugenol by the new rolling process,vanillin by the new coating papermaking process,and 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one(DDMP)by the papermaking-slurry composite process.The main effluents from the pyrolysis of the reconstituted tobacco materials were glycerol,nicotine and minor characteristic aroma components,and all the three types of reconstituted tobacco were suitable for use as the tobacco materials in heated tobacco products.
