PRODUCTION METHOD OF RECONSTITUTED TOBACCO Russian patent published in 2009 - IPC A24B3/14 

FIELD: food industry, tobacco.

SUBSTANCE: invention refers to the technology of tobacco offals processing. Method comprises extracting common origanum blossoms using nonpolar liquefied gas with subsequent deriving corresponding extract; mixing tobacco stuff with liquid carbon dioxide; extracting and chopping tobacco stuff with pressure of extracted mixture recurrently released to the pressure index lower than index of carbon dioxide saturated vapours pressure at a temperature of extracting; separating miscella from oil meal; suspending oil meal in aqueous solution of food acid; adding potable polyatomic alcohol to suspension; moulding, drying to residual humidity 13-15%, cutting suspension, soaking it with gas-liquid common origanum blossoms extract and separated CO₂-miscella with concurrent pressurising; releasing pressure to the index of atmospheric pressure with simultaneous freezing soaked carbon dioxide and subliming it with subsequent deriving desired product in residue.

EFFECT: reducing technological process duration time and deriving reconstituted tobacco with improved organoleptical properties.
