Vacuum tumblers are designed to remove air from the drum, allowing moisture, seasoning, and flavour to more readily enter the food product and distribute flavour and juiciness throughout the whole cut of meat.

Smoking adds new flavor and may increase the shelf life of some poultry meats. Poultry may be given a light smoke to add to the delicate flavor of the poultry, or a heavy smoke, similar to some smoked red-meat products. Adding spices, seasonings and condiments provides distinctive flavors.
