中文摘要:

      将罗望子多糖（TSP）分别添加到造纸法烟草薄片的抄造及涂布工序中，选用烟草薄片配方体系中易挥发的凉味薄荷醇、甜橙油作为涂布液主要添加剂，探究TSP的保香留香功能。通过检测烟草薄片的致香成分含量、涂布率、网部留着率、物理性能并进行感官评价，考察TSP在烟草薄片中的应用效果及影响。结果表明，在涂布工序中添加0.8%（相对于烟草薄片定量，下同）的TSP，（-）-薄荷醇和（+）-柠檬烯在烟草薄片中的保留率相比未添加TSP的烟草薄片分别增大了28.27%和581.81%；涂布率平均值达到最大，为47.90%。在抄造工序中添加0.8%的TSP，网部静态留着率相比未添加TSP的烟草薄片提高了4.64个百分点。相比于涂布工序，在抄造工序中添加TSP制备烟草薄片，对其物理性能改善效果更好，且TSP添加量越大，烟草薄片抗张强度越高，而松厚度、透气度则越低。感官评价结果显示，添加TSP在一定程度上会降低烟草薄片的感官综合评分。

Abstract:

      Tamarind polysaccharide （TSP） was added in forming or coating process of reconstituted tobacco sheets by paper-making method， respectively. Cool flavored menthol and sweet orange oil， which were volatile in the formulation system of reconstituted tobacco sheets， and selected as the main additives of coating solution to observe the fragrance retention function of TSP. The application effect and influence of TSP on reconstituted tobacco sheets were investigated by testing the content of aromatic components， coating rate， retention rate， physical properties， and sensory evaluation. The results showed that the retention rates of （-）-menthol and （+）-limonene in reconstituted tobacco sheets increased by 28.27% and 581.81%， respectively， with the addition of TSP at 0.8% mass fraction （relative to basis weight of tobacco sheets） in coating process compared with that of the reconstituted tobacco sheets without TSP； and the average value of the coating rate reached the maximum of 47.90%. The addition of TSP at 0.8% mass fraction in forming process increased the static retention rate of the web by 4.64 percentage point compared with that of the reconstituted tobacco sheets without TSP. In terms of physical properties， the improvement of physical properties of reconstituted tobacco sheets prepared by adding TSP in forming process was better than that of adding in coating process， and the higher the amount of TSP added， the higher the tensile strength of the reconstituted tobacco sheets， but the lower the looseness and air permeability. The results of sensory evaluation showed that the addition of TSP reduced the sensory score of the finished reconstituted tobacco sheets to a certain extent.
