In order to evaluate the effects of steam blasting on the physical and chemical properties of tobacco stem, the routine chemical components, aromatic components and microscopic structure of tobacco stem blasted under different pressure conditions were investigated. The results showed that the contents of total sugar and reducing sugar decreased correspondingly by 21.63% and 23.46%. The aromatic components including phenylacetaldehyde, furfuryl alcohol, 5-methyl furfural, 2-acetyl furan and furfural in stem increased by 34.25%, 102.97%, 380.49%, 76.24% and 139.39%, respectively. Moreover, the microscopic structure of steam-blasted stem became spongy, with cracked cell wall, along with the disappearance of intercellular gaps and organelle substances.
