Tobacco flavor is a kind of additive used for improving flavor and taste of tobacco products, which is an indispensable raw material in tobacco production. It plays a very important role in covering unpleasant smell and enhancing the original aroma of high-quality tobacco.

The use of tobacco flavor is probably from the 16^th century. The flavor at that time were very simple, only licorice, which is only good for preservation. In the 19^th century, after chewing tobacco was introduced into market, sweetener were added to improve the taste. Since then, tobacco flavor began to be used in the tobacco industry, but only with a limited number of natural substances, such as sugar, cinnamon and their derivatives. In recent years, with the continuous improvement of synthetic flavor, flavor has been widely used in tobacco.

Traditional tobacco flavors include natural flavors and synthetic flavors. Natural flavors are exacted from plant or animal sources without changing its original composition. Synthetic flavors come from man-made chemicals to give a product its particular flavor or aroma.
