The invention discloses a method for extracting tobacco flavors. First, a multifunctional steam distillation-dry distillation integrated device is preheated, and after the temperature is stabilized, tobacco raw materials are added to the steam distillation-dry distillation device; superheated steam and nitrogen are passed through together. Entering the steam distillation-dry distillation device, heating to increase the steam distillation-dry distillation temperature; collecting the distillate of each temperature section according to the temperature; extracting the distillate of each section with a solvent to obtain an extract; dehydrating the extract, and recycling it by rotary evaporation Solvent to obtain tobacco flavor that can be used for flavoring new tobacco products. Compared with the current extraction methods, this method can not only extract the original aroma substances of tobacco, but also obtain tobacco flavors with more roasted and burnt sweetness, and the conditions are more moderate, and the products are easier to be steamed with water vapor. It can improve the yield, avoid the problem of uneven heating and burnt smell that is easy to occur in the dry distillation method, and is especially suitable for the flavoring use of new tobacco products. |
