Operations for the reduction of lipid content in tobacco compositions with retention of favorable organoleptic properties comprising particularly treatments or the selective removal of 'neutral' lipid fraction. Tobacco leaves, preferably freshly harvested, are subjected to physical treatment adapted to remove lipid material from glandular trichome and cuticle while retaining the structural integrity of the leaf. Tobacco compositions based upon treated leaf structures exhibit significantly reduced lipid levels, reported to interrelate with production of aromatic hydrocarbons upon pyrolysis.
