摘　　要：为解决薄荷颗粒在滤棒加香应用中香气易逸失的问题,以薄荷颗粒为原料,通过加入丙二醇改善其持香能力,利用GC-MS联用仪研究丙二醇添加量对薄荷颗粒挥发性香味成分质量分数的影响,优选出丙二醇的最佳添加量,并采用低场核磁共振(LF-NMR)测定了不同丙二醇添加量下薄荷颗粒不同结合状态水分的分布规律,初步探索了薄荷颗粒的持香机理,并将添加丙二醇的薄荷颗粒用于卷烟滤棒加香。结果表明:①未添加丙二醇的薄荷颗粒存放90 d后挥发性成分减少为22种,挥发性成分总量残留40.94%;当丙二醇添加量为2%时,薄荷颗粒的持香能力最强,存放90 d后,其挥发性香味成分残留72.69%,与未添加丙二醇的薄荷颗粒相比,挥发性香味成分保留量增加31.75%。②LF-NMR分析结果表明,添加丙二醇可显著增加薄荷颗粒的水分吸附性能,其中,添加量为2%时,薄荷颗粒中强结合水的质量分数最高。相关性分析结果表明,薄荷颗粒挥发性成分残留量与其强结合水相对峰面积显著正相关,薄荷颗粒中强结合水所占比例越高,薄荷颗粒挥发性成分残留量越多。③添加丙二醇的薄荷颗粒能够明显提升卷烟烟气的薄荷香气并增加一定润感。To minimize aroma loss of peppermint powders in cigarette filter rods,the aroma retention capacity was promoted by adding propylene glycol(PG)to peppermint powder.The effect of PG addition rate on the mass fractions of volatile aroma components in peppermint powders was analyzed by GC-MS.The optimal PG addition rate was determined,and the distribution characteristics of moisture in different binding states with peppermint powders were measured by low-field nuclear magnetic resonance(LF-NMR).The aroma retention mechanism of peppermint powders was investigated,and the peppermint powders with added PG were used to flavor cigarette filter rods.The results showed that:1)The number of volatile aroma components in peppermint powders without PG decreased to 22 after storage for 90 days,and the total amount of volatile aroma componentsremained 40.94%.When the addition rate of PG was 2%,the peppermint powders had the strongest aroma retention capacity,the total amount of volatile aroma components remained 72.69%after storage for 90 days,the retention amount of volatile aroma components was increased by 31.75%by adding PG.2)The results of LF-NMR analysis showed that the addition of PG significantly increased the moisture adsorption ability of peppermint powder.At 2%PG addition,the mass fraction of strongly bound water in peppermint powders was the highest.Correlation analysis results showed that the residual amount of volatile components in peppermint powders was significantly positively correlated with the relative peak area of strongly bound water.The higher the proportion of highly bound water in peppermint powder,the higher the amount of residual volatiles in peppermint powder.3)The peppermint powders containing PG significantly enhanced the menthol flavor of cigarette smoke and increased the moisturizing sensation to some extent.
