METHOD FOR PRODUCING RECONSTITUTED TOBACCO Russian patent published in 2009 - IPC A24B3/14 

FIELD: tobacco products.

SUBSTANCE: method includes valeriana extraction by liquid carbon dioxide with corresponding miscella separation, mixing of the tobacco materials with non-polar liquefied gas; its extraction and blending together with periodical depressurising in the extraction mixture to lower the pressure of the moist steam of the extract at the extraction temperature; separation of miscella and oil meal; slurring the oil meal in the aqueous solution of edible acid; introducing of edible polyalcohol in the liquor; its forming, drying till residual humidity of 13-15%; cutting and steeping in gas-liquid tobacco extract and separated CO₂ miscella with simultaneous pressure increase; depressurising to atmospheric pressure with simultaneous freeing of soaked carbon dioxide and its distillation to obtain in the remnant the target product.

EFFECT: shortening the duration of technological process and obtaining reconstituted tobacco with improved organoleptical properties.
