[Objective]The present paper aimed to search for some technical methods which could reduce the tar content of reconstituted tobacco effectively. [Method]The effect of some factors such as ratio of stems to leaves, beating degree, basis weight, coating rate, proportion of plus fiber and calcium carbonate on the tar content of paper-making reconstituted tobacco was studied and those factors that could reduce the tar content effectively had also been verified. [Result] (i)Beating degree, basis weight, proportion of plus fiber, potassium salt and calcium carbonate had significant influence on the tar content of paper-making reconstituted tobacco;(ii)The ratio of stems to leaves of raw materials also had a certain influence on the tar content of paper-making reconstituted tobacco, and the tar content was the lowest when the ratio of stems to leaves was 2-1;(iii)There was a positive correlation between the coating rate and the tar content of paper-making reconstituted tobacco, the increase of coating rate would lead to the increase of tar content.(IV) The tar content of paper-making reconstituted tobacco prepared under a set of factors, including fiber proportion, beating degree, basis weight had fallen by more than 50 % ,and blending it in cigarette products had also reduced the tar content of cigarettes obviously. [Conclusion] The tar content of reconstituted tobacco could be reduced by adjusting the process parameters. While the PRT sample integrated with some tar-reduced factors was blended into cigarettes, it could greatly reduce the tar content of cigarettes. Therefore, some technical methods could be taken properly to reduce the tar content of PRT, and achieve ‘ reducing the harmful and tar content’ after blending it into cigarettes.
