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.
