FIELD: tobacco industry. ^ SUBSTANCE: method relates to producing reconstituted tobacco. Under the proposed method jasmine bloom is extracted with liquid carbon dioxide to isolate the respective miscella. Tobacco material is mixed with liquid carbon dioxide and extracted with the pressure in the extraction mixture bulk periodically relieved to be below the saturated carbon dioxide vapour pressure at extraction temperature. The raw material cellular structure is thereby destroyed. The miscella and meal are separated. The obtained miscellae are mixed. The meal is suspended in water solution of an edible polybasic acid supersalt; potable polyatomic alcohol is added to the suspension. Then the suspension is moulded, dried for residual moisture content to be 13-15% and cut. Then it is imbued with the miscellae mixture under increasing pressure. After that depressurisation is done to the atmospheric pressure level combined with the absorbed carbon dioxide freezing. Finally, sublimation yields the target product. ^ EFFECT: improvement of reconstituted tobacco organoleptical properties and reduction of technological process duration. ^ 1 ex |
