<p>This invention describes a pressurised drying process particularly useful for changing the aroma of Burley tobacco, and the taste and flavour of cigarettes comprising such processed tobacco. Burley tobacco is treated in a pressurised dryer at temperatures of 120 °C or more in a pressure range of 0.25-7 Bar absolute to provide a processed Burley tobacco with a more toasted character. Other tobaccos may also be treated in a similar manner to effect a change in expansion.</p> |
