【摘要】 探究牡丹江烟区复烤片烟在河南仓储自然醇化过程中的质量变化，为河南烟草工业公司合理利用牡丹江片烟原料提供理论依据。将龙江911品种复烤片烟贮存于河南新郑醇化库进行自然醇化，研究醇化片烟外观、感官质量及主要化学成分变化，分析主要化学成分与感官质量的相关性。结果表明，片烟外观质量在醇化24个月时达到最佳，感官质量在醇化27个月时达到最佳。随着醇化时间的延长，片烟的总氮、总植物碱、总糖、还原糖含量，以及多酚类和游离氨基酸类总含量均呈下降趋势，有机酸类总含量呈上升趋势。与醇化9个月时相比，醇化30个月时片烟的总氮和总植物碱含量分别降低15.23%和1.49%，总糖和还原糖含量分别降低3.48%和7.02%，多酚类和游离氨基酸类总含量分别降低9.41%和10.30%，有机酸类总含量增加15.70%。相关分析表明，香气质和杂气均与总氮含量呈显著负相关，与有机酸类总含量呈显著正相关；香气量与总氮、还原糖含量呈极显著负相关；感官质量总分与总氮、总糖、还原糖含量和多酚类总含量呈极显著负相关，与有机酸类总含量呈显著正相关。总之，牡丹江片烟在河南新郑醇化库自然醇化27个月时，感官评吸质量和内在化学成分协调性最佳，此时进行加工利用，既可以保证卷烟质量又能节约仓储养护成本。更多还原

【Abstract】 To explore quality changes of redried tobacco strips from Mudanjiang tobacco growing area in warehouse of Henan Province during natural aging,and to provide theoretical basis for the rational use of Mudanjiang tobacco strips by tobacco industry company of Henan Province,we stored the Mudanjiang tobacco strips of Longjiang 911 variety in Xinzheng warehouse of Henan Province,investigated the changes of appearance,sensory quality and main chemical components of tobacco strips,and analyzed the correlation between main chemical components and sensory quality during natural aging. The results showed that the appearance quality of tobacco strips was the best at the age of 24 months,and the sensory quality was the best at the age of 27 months. The contents of total nitrogen,total plant alkaloid,total sugar,reducing sugar,total polyphenols and total amino acids in tobacco strips decreased,while the content of total organic acids enhanced with the increasing of aging time. Compared with 9 months of aging,after 30 months of aging,total nitrogen and total plant alkaloid contents of tobacco strips decreased by 15. 23% and 1. 49% respectively,total sugar and reducing sugar contents decreased by 3. 48% and7. 02% respectively,the contents of total polyphenols and total amino acids decreased by 9. 41% and10. 30% respectively,and the total amount of organic acids increased by 15. 70%. The correlation analysis showed that both aroma quality and offensive odor were significantly negatively correlated with the content of total nitrogen and significantly positively correlated with the content of total organic acids.The amount of aroma was extremely significantly negatively correlated with the content of total nitrogen and reducing sugar. The total sensory score was extremely significantly negatively correlated with the contents of total nitrogen,total sugar,reducing sugar and polyphenols,and significantly positively correlated with total amount of organic acids. In general,naturally aging for 27 months,Mudanjiang tobacco strips achieve the best sensory evaluation quality and internal chemical composition coordination in Xinzheng warehouse of Henan Province,and at this time,tobacco industry companies can use Mudanjiang tobacco strips,which can not only ensure cigarette quality but also save warehouse maintenance costs.更多还原
