The invention refers to the tobacco industry, namely to the technique for manufacture of tobacco products, in particular to their composition and may be used for the improvement of their organoleptic properties. By adding into the tobacco products, including the sauced tobacco mixture consisting of tobacco types "Virginia", "Burley", "Oriental", reconstituted tobacco with expanded nerves, with aromatic compositions containing as active ingredient the aromatizing product, having in its composition a mixture of manoyloxides, (13S)-8?,13,20,13-dioxido-15,14-bisnorlabdane, 8-epi-norambreinolide, norambreinolide and 15,14-bisnorlabd-8(9)-en-7,13-dione, it is improved the aroma and taste of the tobacco smoke, perfectly harmonizing with tobacco aroma.The aromatizing product is obtained on the basis of sclareol labdanoic diterpenoid by oxidative cleavage thereof with chromic acid mixture in the medium of C5-C7 hydrocarbons (nephras) or toluol. By varying the quantity of the oxidant and the reaction time one can obtain products, differing in the quantitative content of the components, being preserved their aromatizing properties.Claims: 7 |
