Optimum technological parameters of extraction for the sum of tannins from tobacco dust (Nicotiana tabacum L) waste of tobacco production were established. The basic process parameters to obtain the highest yield of tannins from raw materials such as selection of optimum extractant ratio of raw material to solvent, extraction time, temperature and mode, selection of the optimal precipitator for tannins and the optimal ratio of extract to precipitator. A process technological scheme of tannins extraction from tobacco dust waste was suggested.
