Abstract: To explore the effects of three⁃dimensional warehouse（stereoscopic warehouse） and plane warehouse（flat warehouse）on the aging quality of re⁃dried tobacco strips，the formula⁃based re⁃dried strip tobacco from multiple producing areas in Yunnan Province was taken as the research object，and the changes of conventional chemical composition，biological enzyme activity，aroma substances and sensory quality after 6，9，12 and 14 months of alcoholization in Kunming stereoscopic warehouse（GJ）and flat warehouse（PK）were compared. The results showed that in the 14 months aging period，GJ aging had a better effect on the quality of re⁃dried tobacco strips. The contents of reducing sugar，total nitrogen，total plant alkaloid and schmuck value of tobacco strips were 1.69%，2.51%，1.26% and 1.07% higher than those of PK，respectively，and the chemical composition was more coordinated.The activities of α⁃amylase and neutral protease were significantly increased by 73.33% and 66.55%，respectively，and the activity of cellulase was slightly higher. The contents of chlorogenic acid and rutin were significantly increased by 5.86% and 3.00%，respectively. Meanwhile，the aroma components of GJ tobacco were more abundant，among which the enrichment levels of key aroma substances such as 2⁃acetylpyrrole and methyl palmitate were higher than those of PK. In the corresponding sensory evaluation，the scores of aroma quality，aroma intensity，permeability，mixed gas and cleanness were 3.17%，3.17%，8.33%，3.17% and 3.17% higher than those of PK，respectively.Further correlation analysis revealed that the contents of aroma components and their precursors，including methyl hexadecanoate，methyl linolenate，2⁃acetylpyrrole，2，3'⁃bipyridine，shyobunone，3⁃hydroxy⁃2⁃butanone，and rutin，were significantly positively correlated with the storage environment of GJ.In conclusion，the aging environment of GJ is more conducive to maintaining enzyme activity and promoting formation of aroma components，thereby improving the comprehensive quality of strip tobacco requiring long⁃term storage.

摘要： 为探究立体仓库（高架库）与平面仓库（平库）对复烤片烟醇化品质的影响，以云南省多产地混打配方复烤片烟为研究对象，比较其在昆明市的高架库（GJ）与平库（PK）中醇化6、9、12、14月后，常规化学成分、生物酶活性、致香物质及感官品质的变化。结果表明，于14月醇化周期中，GJ醇化对复烤片烟的品质促进效果更好，其片烟还原糖、总氮、总植物碱含量和施木克值分别高出PK 1.69%、2.51%、1.26%、1.07%，化学成分更协调；α-淀粉酶和中性蛋白酶活性分别显著提升73.33%、66.55%，纤维素酶活性略高；致香前体物质绿原酸、芸香苷含量分别显著提升5.86%、3.00%。同时，GJ片烟的香气成分种类更丰富，其中，2-乙酰吡咯、棕榈酸甲酯等关键香气成分富集水平高于PK。对应感官评价中，其香气质、香气量、透发性、杂气、干净程度等指标得分分别高于平库3.17%、3.17%、8.33%、3.17%、3.17%。相关性分析进一步显示，棕榈酸甲酯、亚麻酸甲酯、2-乙酰吡咯、2，3'-联吡啶、菖蒲酮、3-羟基-2-丁酮和芸香苷等香气及香气前体物质含量与GJ环境呈显著正相关。综上，高架库醇化环境更有利于维持酶活性和促进香气成分形成，从而提升需长期贮存片烟的综合品质。
