| 摘要 |
<p>The present invention provides a packaging system comprising a sealed or re-sealable package containing a tobacco product, wherein the internal environment within the package is actively controlled to maintain a predetermined gaseous composition. Maintaining the oxygen level below atmospheric levels slows undesirable changes to the product resulting from oxidative processes. The sealed or re-sealable package prevents unwanted loss of moisture content and flavour of the tobacco product, whilst maintaining the oxygen concentration in the package above zero prevents the rapid deterioration in the sensory quality of the tobacco product associated with a zero oxygen environment, thereby extending the shelf-life of the product.</p> |
