摘　　要：通过开发快速且条件温和的反应方法,在降低梗签木质素含量的同时,提升其发烟剂负载量,以解决目前加热卷烟发烟剂负载量低、杂气重的问题。使用加热卷烟常用的发烟剂(丙二醇和甘油)作溶剂,采用溶剂热法处理梗签,采用GC-FID、FTIR、SEM等表征样品,研究了反应前后梗签的木质素去除率及发烟剂负载量,且采用辊压法将处理后的样品制成再造烟叶并应用在加热卷烟样品中进行评吸。结果表明,不同浓度的发烟剂对烟梗原料处理后,烟梗中木质素含量降低53%~63%,反应温度和反应时间对于木质素去除率有一定影响;不同浓度发烟剂处理后,样品中丙二醇的负载量最高为8.8%,甘油的负载量最高为33.9%;不外加发烟剂的条件下,使用处理后的梗签样品制备的加热卷烟样品烟雾量充足,持续性较好。该方法不仅显著降低梗签中的木质素含量,同时,还显著提高了发烟剂的负载量,并提供了新的思路来提升加热卷烟辊压法再造烟叶的品质。In order to increase the capacity of smoking agent of reconstituted tobacco sheet for heated tobacco product and reduce its lignin content,a solvothermal method using propyl glycol and glycerol as solvents was applied.Techniques including GC-FID,FTIR and SEM were employed to characterize the obtained the fresh and treated sliver samples.It was found that 53%-63%of lignin was eliminated using different ratio of propyl glycol and glycerol as solvent.Furthermore,the highest of 8.8%propyl glycol and 33.9%glycerol were reserved in sliver samples.More importantly,a heated tobacco product sample was produced with the treated sliver using rolling method without adding extra smoking agent,which shows considerable amount of aerosol.The developed pretreatment of sliver provides a promising technology for production of reconstituted tobacco sheet for heated tobacco product.
