Abstract

The invention relates to the manufacture of a nicotine-containing crude tobacco material from green tobacco by means of a process in which the tobacco plant material is converted to a pulp which is divided into a solid, coarse fraction and a liquid fraction. Suspended or emulsified fine material is then separated from the liquid fraction, resulting in a leaf nutrient concentrate containing pigment. This concentrate is divided into several pigment fractions with the aid of different extraction processes and these fractions are suitably treated and then optionally returned to the first, solid coarse fraction to enhance the flavour and appearance of the products. Proteins present in the liquid fraction left over at separation of leaf nutrient concentrate are totally removed, whereafter the deproteinized liquid fraction is processed while retaining the nicotine, so as to obtain a concentrated liquid phase that contains nicotine, flavourants and colourants and is then returned to the solid, coarse fraction, optionally together with other additives, so as to obtain the desired crude tobacco material. The invention also relates to the crude tobacco material obtained, intended for smokable and smokeless nicotine-containing products which in use have considerably reduced mutagenicity according to the Ames test and a low TSNA content.
