目前,电加热不燃烧型烟草制品作为新型烟草制品的重要分支,也是市售的主要产品类型.本文主要介绍了跨国烟草公司的市售产品特点,以及近几年国内烟草企业在电加热不燃烧烟弹产品开发情况,从产品类型、烟弹结构和烟芯材料等方面对电加热不燃烧型烟草制品的产品情况进行了综述.结果表明:三大跨国烟草公司的市售产品各有特点,产品技术成熟,销售状况良好;国内烟草企业在烟弹的研发上,其尺寸和结构主要参照跨国烟草公司的产品进行开发;在烟芯材料的开发上,跨国烟草公司的市售烟弹产品主要是再造烟叶和颗粒,而国内企业除了在再造烟叶和颗粒上有较多研发外,还开发有烟丝、梗丝、成形纸等烟芯材料产品,部分烟芯材料产品如干法再造烟叶等已具备规模化生产的能力.

The influence of coating rate on the properties of air-laid process tobacco sheet was discussed by five theoretical levels(50. 00%,66. 67%,75. 00%,80. 00% and 83. 33%) so as to determine a rea-sonable coating rate. The results showed that, with the increasing of the coating rate in the product, its quantitation,thickness, tensile strength went up gradually, while the bulk, filling value reduced by de-grees;its total sugar,reducing sugar,nicotine,nitrate,potassium and chloride showed a linear rise; the release amount of TPM,nicotine,Tar,CO showed a regular increasement; the sensory quality level went up rapidly and then became flat. The optimum coating rate was finally determined as 80% or so.

After air-laid process tobacco sheet was shredded,samples with different breakage rates(theo-retical value was separately 0,2%,4%,6%,8%,10%,12% ) were prepared,and the influence of brea-kage rate on the property of air-laid process tobacco sheet was discussed,so as to determine a reasonable rate to guide the production of air-laid process tobacco sheet. Through the research in its chemical indica-tors,smoke components,aroma components and sensory quality,the results showed that:When the brea-kage rate was less than or equal to 8. 36%,the property of air-laid process tobacco sheet kept stable,and once it went over 8. 36%,the sensory property descended obviously,while the other indexes suffered no apparent effect. Therefore in the production of air-laid process tobacco sheet,the breakage rate should less than 8. 36% .

In order to find an appropriate doping content of air-laid process tobacco sheet in tobacco industry,based on cut tobacco from some famous cigarette,add air-laid process tobacco sheet was added into the tobacco material by 5%, 8%, 12% and 15% separately, and the effects of air-laid process tobacco sheet on qualities of cigarette with different blending ratios were discussed. The results showed that air-laid process tobacco sheet could effectively reduce the values of cigarette chemical index and smoke index when it was added into pipe tobacco. When the doping content reached 15%,compared with the ones without air-laid process tobacco sheet(pure cut tobacco) ,the total sugar,reducing sugar,nicotine content of cigarette materials decreased separately by 14 . 64%, 16 . 59%, 35 . 68%, and the release amount of nicotine, tar and CO decreased separately by 17. 50%,15. 03%,11. 55%,which were also better than ones added by paper-making reconstituted tobacco in the same proportion. The suction properties of the cigarettes added by air-laid process tobacco sheet exceeded the ones added by paper-making reconstituted tobacco and the pure cut tobacco,while 8% was the appropriate mixing ratio. So,the abilities of air-laid process tobacco sheet in cigarette quality improvement and harmful components control met or even exceeded paper-making reconstituted tobacco.

By analyzing the chemical indexes,smoke indexes,harmful components and aromatic components along with sensory evaluation during primary processing,the effects of primary processing on the quality of air-laid process tobacco sheet were studied with the purpose of providing scientific basic for the application of air-laid process tobacco sheet in cigarette flavoring. The results showed that after loosening and conditioning,casing and strip bulking,ordering and cut tobacco drying,the contents of total sugar and reducing sugar were slightly increased,while the nicotine content presented a decreasing tendency.The total particulate matter,TAR,CO and other harmful components also presented downtrend and the hazard index was reduced by 4.52%.After primary processing,the total contents of most aromatic components were slightly higher than that before processing.The contents of important aromatic components such as megastigmatrienone,β-damascenone, neophytadiene,β-damascone and geranylacetone were increased obviously.The sensory quality of air-laid process tobacco sheet was significantly improved,which mainly manifested as an improvement in sweet feeling and smoke clarity.It is concluded that primary processing has a promoter action on the inherent quality of air-laid process tobacco sheet and air-laid process tobacco sheet can adapt to primary processing well.
