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

FIELD: tobacco products.

SUBSTANCE: method involves extracting lemon balm with liquid carbon dioxide and separation of respective miscella. Then the tobacco material is mixed up with a non-polar liquefied gas. 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 the miscella and meal are separated, a respective extract is obtained from the miscella, and the meal is suspended in an aqueous solution of acid salt of edible polycarboxylic acid. Then edible polyatomic alcohol is introduced into the suspension. The suspension is formed, dried to a residual humidity of 13-15%, cut and treated with the gas-liquid tobacco extract and separated CO₂ miscella by raising simultaneously the pressure. Then the pressure is relieved to atmospheric one by freezing simultaneously the soaked carbon dioxide and the latter is sublimed to obtain a target product in the residue.

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