Tobacco Stem
Tobacco stem, also known as tobacco midrib, is the central vein of the tobacco leaf that remains after the leaf lamina is stripped during processing. It is obtained from cured tobacco leaves and is separated before cutting or blending. Tobacco stems are firmer and more fibrous than leaf portions and are commonly cut, crushed, or ground for use in chewing tobacco, snuff, reconstituted tobacco, and as a blending material. They help in controlling strength, texture, and moisture retention in finished tobacco products and are widely traded as a by-product of tobacco processing.
