Abstract
A method of processing tobacco and its by-products, comprising the steps of, preparing a blend of the tobacco and its by-products; charging an extruder with the blend; heating the blend to a temperature comprised between 10° C. and 170° C.; applying a pressure to the blend of between 0 bar and 40 bar; said heating and applying a pressure reducing ammonia content and causing Maillard reactions in the blend; and extruding said blend from the extruder to obtain an extruded product, the extruded product having reduced ammonia content.
Claims17
A method of processing tobacco and its by-products, comprising the steps of,
- preparing a blend of the tobacco and its by-products, wherein a content of by-products is between 5 and 20 wt % of the tobacco and tobacco by-products;
- charging an extruder with the blend;
- adding water to the blend so that the blend has a moisture content of between 5 wt % and 20 wt %
- heating the blend, after water has been added to the blend, to a temperature comprised between 10° C. and 170° C.;
- applying a pressure to the blend of between 0 bar and 40 bar;
- said heating and applying a pressure reducing nitrosamines and ammonia content and wherein the amount of water added to the blend, the temperature to which the blend is heated and the pressure applied to the blend pressure applied is such that selected components in the blend undergo Maillard reactions;
- and
- extruding said blend from the extruder to obtain an extruded product, the extruded product having less nitrosamines and ammonia and nitrosamines content than the blend, the duration of the extrusion process being between about 1 and 3 minutes.
Use of tobacco product comprising tobacco and tobacco by-products processed by a method comprising the steps of,
- preparing a blend of the tobacco and its by-products, wherein a content of by-products is between 5 and 20 wt % of the tobacco and tobacco by-products;
- charging an extruder with the blend;
- adding water to the blend so that the blend has a moisture content of between 5 wt % and 20 wt %
- heating the blend, after water has been added to the blend, to a temperature comprised between 10° C. and 170° C.;
- applying a pressure to the blend of between 0 bar and 40 bar;
- said heating and applying a pressure reducing nitrosamines and ammonia content and wherein the amount of water added to the blend, the temperature to which the blend is heated and the pressure applied to the blend pressure applied is such that selected components in the blend undergo Maillard reactions;
- and
- extruding said blend from the extruder to obtain an extruded product, the extruded product having less nitrosamines and ammonia and nitrosamines content than the blend, the duration of the extrusion process being between about 1 and 3 minutes;
- in cigarettes, cigarillos or cigars.
