[0077] The inventors analyzed the technical solution of the present invention and believed that:

[0078] The tobacco flavor of the present invention increases the vanilla and cream flavors of tobacco and provides a basic sweet taste by adding vanillin and ethyl vanillin; 2-methylpyrazine, 2,3-dimethylpyrazine and 2,3,5-trimethylpyrazine are used to increase the roasted and nutty flavors of tobacco and simulate the burnt aroma of rice; although the content of rose essential oil and ethyl phenylacetate is very low, a small amount of addition can increase the layered sense of aroma in the tobacco flavor, improve the overall aroma quality of tobacco, and improve the coordination of tobacco; isophorone, α-damascenone and β-damascenone are used to increase the sweetness and fruitiness of tobacco, which is the key to forming the caramel flavor and balances the bitterness of tobacco; mushroom alcohol provides the flavor of soil or mushrooms, increases the naturalness and depth of the tobacco flavor, and makes the phase of the tobacco richer and more complex; octanal provides a fresh feeling and a citrus flavor, thereby balancing the smoky taste of tobacco and making the tobacco aroma more vivid; ethyl hexadecanoate provides a sweet and fruity flavor, moderates and balances the bitterness and spiciness of tobacco, and increases the sweetness of tobacco. The three compounds are used together to enhance the aroma level of tobacco, improve the overall flavor of tobacco, and make the smoke more harmonious, rich and pleasant.

[0079] In short, the addition and compounding of the above substances give tobacco a special rice aroma. At the same time, the flavor can balance the smoky taste of tobacco, moderate and balance the bitterness and spiciness of tobacco, increase the layering of aroma, and enhance the overall aroma quality of tobacco, improve the coordination of tobacco, enhance the overall flavor of tobacco, and make the smoke more harmonious, rich and pleasant.
