ABSTRACT:
An improved process for expanding tobacco is disclosed wherein tobacco components such as stems, midribs and veins are contacted with an alkaline-hydrogen peroxide solution to effect expansion, washed and then dried and/or roasted to produce an expanded tobacco material highly suitable for use in smoking products. Prior to contact with the alkaline hydrogen peroxide solution, the tobacco materials are subjected to a pretreatment step with gaseous ozone to prevent clumping and/or interadherence of the tobacco shreds which would otherwise occur during the drying step.
