To investigate the change law of physical index and sensory quality of cut tobacco after expansion with different levels of tobacco leaf under various CO2expansion temperatures,the representative tobacco leaf were selected to design small formula module,and the leaf groups were expanded in 240,280,280 ℃,respectively.The result showed:Upper leaf has better processability resistance,is suitable for high temperature of CO2expansion processing;Middle tobacco leaf is suitable for low temperature,to retain the aroma of smoke and concentration;Lower leaf has loose tissue and poorer processability resistance,is more suitable for the expansion of the lower temperature;while variegated leaf has low quality,high offensive odor and irritation,is suitable for high temperature expansion,but after expansion the cut tobacco structure and filling value are reduced slightly.
