Method for extracting tobacco flavor components

PendingCN119523142AIncrease contentNo impact on securityTobacco preparationTobacco treatmentAlcohol ethylDistillation
The invention discloses a method for extracting tobacco flavor components, which comprises the following steps: distillation-dry distillation, collection and elution recovery: the distillation-dry distillation comprises the following steps: adding tobacco into a dry distillation device, preheating the dry distillation device, introducing superheated steam into the dry distillation device, and collecting the tobacco flavor components; heating the dry distillation device until the temperature in the kettle is 100-450 DEG C so as to simultaneously perform distillation and dry distillation on the tobacco; the collection comprises collection of distillates distilled in the whole distillation-dry distillation process; the elution recovery comprises the following steps: adding ethanol into the distillate, placing the distillate in refrigeration equipment, carrying out alcohol precipitation, carrying out coarse filtration, and finally carrying out membrane filtration to obtain a solution containing tobacco aroma components. According to the method, the process steps are further optimized, so that the production process is simplified, meanwhile, the yield of the tobacco aroma components is increased, and the pollution to the environment is reduced.
