摘　　要：为了考察烷烃对烟丝保润性能的影响，测定了29种烟丝的烷烃含量，按照烟草保润性能的评价方法对29种烟丝样品进行保润性能评价，并将烷烃类返加到烟丝样品中以验证其对烟丝保润性能的影响。结果表明：①烟丝失水量与烷烃含量显著负相关，即烷烃含量越高，烟丝失水越少，与失水量显著性相关的烷烃主要集中于C29 H60～C35 H27之间；②加入不同烷烃含量保润剂的烟丝，其平衡含水率顺序为：1．0％固体石蜡（保润剂1#）〉0．5％固体石蜡（保润剂2#）〉0．1％固体石蜡（保润剂3#）〉空白；当含水率由14％降低至12％时，所需总时间长短顺序为：保润剂1#〉保润剂2#〉保润剂3#〉空白。烟叶烷烃对烟丝的保润性能有一定程度的提高作用，烷烃类的加入量越大，烟丝保润性能提高越明显。To find out the effect of alkanes content on the moisture retentivity of cut tobacco, the contents of alkanes in 29 samples of cut tobacco were determined. The moisture retentivity of the samples was also evaluated, and alkanes were added back to the samples to validate their effects on the moisture retentivity of cut tobacco. The results showed that： 1） The moisture loss of cut tobacco significantly negatively correlated to alkane content, i.e., the higher the alkane content was, the less the moisture lost. The alkanes which significantly correlated with moisture loss were mainly those in the range of C29H60-C3,Hn. 2） The samples added humectants containing different alkane levels in the order of equilibrium moisture content were sample added Humectant 1 （1% solid paraffin）〉 sample added Humectant 2 （0.5% solid paraffin）〉 sample added Humectant 3 （0.1% solid paraffin） 〉 control, their sequence were the same in the order of duration when the moisture content in samples reduced from 14% to 12%. Tobacco alkanes tobacco to a certain extent, the effect was more obvious at were able to improve the moisture retentivity of cut higher adding rate.
