Abstract: In a tobacco flavoring agent containing ascorbic acid, a salt or isomer thereof, a chlorophyll-containing material, and potassium nitrate, the maximum particle size of the potassium nitrate is set to 0.8 mm or less, making it possible to obtain a tobacco flavoring agent that lowers the tar or nicotine content of tobacco smoke, maintains a burning portion of tobacco in a stable state, and preserves its powdery state. This tobacco flavoring agent may be used by being deposited on the tips of cigarettes or other tobacco products, or by being mixed with shredded tobacco leaves.
