Abstract: In order to develop new-type tobacco products with Chinese characteristics, Siraitia grosvenorii, a medical and edible homologous plant from Guangxi, was selected as raw materials to extract and prepare the oral tobacco flavors by ethanol extraction and biological enzymatic hydrolysis technology. Flavor ingredients were extracted by simultaneous distillation extraction method. Volatile components were analyzed and identified by gas chromatography-mass spectrometry. The results showed that 22 and 30 aromatic components were separated and identified by ethanol extraction and enzymatic hydrolysis respectively. Aromatic components extracted by enzymatic hydrolysis were more abundant, and aroma characteristics were richer and mellower. The flavoring tests were carried out by adding the flavoring extract after enzymatic hydrolysis to oral tobacco products, the taste was the best when the flavoring concentration was 30%. It not only improved the coordination and comfort of the taste of oral tobacco products, but also provided consumers healthier options and gave the product diversified functions.
