Expanded Stem is often used in American blend cigarettes because of its economic and technical benefits.
Expanded Stem reduces the cigarette weight, while preserving the natural tobacco taste. It increases the filling value and burn rate, which reduce the number of puffs, which in turn reduce the tar and nicotine deliveries per cigarette.
The Expanded Stem is usually included in the blend at 5 to 10 percent at full-flavor cigarettes, and 10 to 15 percent or more in light or ultra-light cigarettes.
Expanded Stem (ES) is considered as one of the main tools for reducing harm of tobacco products. Expanded Stem are rolled, flattened, and shredded tobacco leaf stems that are expanded by being soaked in water and rapidly heated. Then it is dried.
The Expanded stem can be also used as a means for reducing standard ISO tar and nicotine yields
The rate of Expanded Stems with absolutely neutral taste in cigarettes may increase up to 30% without creating a negative after taste or change in blend characteristics. It can be also used as a means for reducing standard ISO tar and nicotine yields. Expanded Stem, in particular, imparts firmness to tobacco rods.
