METHOD FOR PRODUCING RECONSTITUTED TOBACCO Russian patent published in 2009 - IPC A24B3/14 A24B15/18 

FIELD: tobacco products.

SUBSTANCE: method involves extracting cinnamon with liquid carbon dioxide and separating a respective miscella. The tobacco material is mixed up with a non-polar liquefied gas and then the material is extracted and shredded by relieving periodically the pressure in the extraction mixture below the extractant moist steam pressure at extraction temperature. Then miscella and oil meal are separated, corresponding extract is separated from miscella, the oil meal is slurred in the water solution of acid salt of edible polybasic acid, edible polyatomic alcohol is introduced in the liquor. The liquor is formed, dried till residual humidity of 13-15%, cut and steeped in gas-liquid tobacco extract and separated CO₂ miscella with simultaneous pressure increase, depressurising to atmospheric pressure with simultaneous freezing of soaked carbon dioxide and its distillation is carried out to obtain in the remnant the target product.

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