摘　　要：通过气相色谱质谱技术、超高效液相色谱质谱技术分析再造烟叶浓白水中致香成分,采用大孔树脂富集浓白水中致香成分并优化富集工艺参数,考查不同富集组分对卷烟感官品质的影响。结果表明:浓白水中主要致香成分为烟碱,质量浓度约为63 mg/L,还含有少量的3-氧代-α-紫罗兰酮、苯乙醇、去氢新烟碱等成分;LS313型大孔树脂最适用于富集浓白水中的致香成分,最佳富集工艺为上样流速11 mL/min,上样量8.2 L,洗脱溶剂为无水乙醇,洗脱流速2 mL/min,乙醇用量140 mL,该条件下洗脱液中烟碱质量浓度相对于浓白水提高了53倍,回收率为92.6%,表明大孔树脂法对浓白水中致香成分有较好的富集效果;富集组分对卷烟样品感官品质具有不同的正向作用,主要影响烟气浓度、劲头和烟香。The aroma components in cloudy water of reconstituted tobacco were analyzed by GC-MS and UPLC-MS,macroporous resin was used to enrich the aroma components incloudy water and the enrichment process parameters were optimized,and the effects of different enrichment components on the sensory effects of cigarettes were investigated.The results showed that the main aroma components in cloudy water was nicotine,with a content of 63 mg/L,and a small amount of 3-oxo-α-ionone,phenylethanol,anatabine and other aroma components were also contained.The macroporous resin LS313 possessed the best enrichment effect.The optimal enrichment parameters were as follows:the feeding rate was 11 mL/min,the loading volume was 8.2 L,absolute ethanol as the eluent solvent,elution rate was 2 mL/min,and the amount of ethanol was 140 mL.Under these conditions,the mass concentration of nicotine in the enriched solution was 53 times higher than that in cloudy water,and the recovery rate of nicotine reached 92.6%,indicating that the macroporous resin method had a good enrichment effect on the aroma components in cloudy water.The enrichment and separation solution had different positive effects on the sensory quality of cigarette products,mainly affecting the smoke concentration,cigarette impact and aroma of the products.
