METHOD OF MANUFACTURING RECOVERED TOBACCO MATERIAL Russian patent published in 2008 - IPC A24B15/00 A24B15/12 A24B15/24 A24B3/14 

FIELD: food industry.

SUBSTANCE: method relates to manufacturing recovered tobacco material. The method involves extraction of natural tobacco material by water extraction solvent to produce extraction solution containing natural tobacco material components and extraction residue. The extraction solution is subject to adsorptive fractionation using adsorbent to reduce nitrosamine quantity. Recovered tobacco material is prepared with using extraction residue. At least part of extraction solution with reduced nitrosamine quantity is introduced to the recovered tobacco material. High hydrophobic adsorbent is used as adsorbent. Adsorptive fractionation is carried out during 60 minutes using high hydrophobic adsorbent in the amount of 10-110% of the weight of soluble components in the extraction solution.

EFFECT: controlling content of nitrosamines and nicotine in the extraction solution.
