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

FIELD: tobacco products.

SUBSTANCE: method of reconstituted tobacco production implies wild marigold flowers extraction using non-polar liquefied gas, obtaining corresponding extract as a result of this procedure, and mixing of tobacco material with liquid carbon dioxide. The material is extracted and shredded by relieving periodically the pressure in the extraction mixture below the pressure of carbon dioxide moist steam at extraction temperature. Then miscella and oil meal are separated. The oil meal is slurred in the water solution of acid salt of edible polycarboxylic acid and edible polyatomic alcohol is introduced into liquor. The liquor is formed, dried till residual humidity of 13-15%, cut, steeped in gas-liquid wild marigold flowers extract and separated CO₂ miscella with simultaneous pressure increase. Then the process of 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.
