The result showed stick-hanging bulk curing barn caused most alkane loss, and the total amount of alkane in cured leaf was reduced by 58.9% compared with the uncured leaf, which was mainly occurred during yellowing and stem-drying stages; basket-holding bulk curing barn had the least alkane loss, and the total amount of alkane in cured leaf was only reduced by 13.8% compared with the uncur
