Abstract

La présente invention concerne un procédé d'amélioration du tabac par dégradation des nitrates et des nitrites qu'il contient. Procédé caractérisé en ce que l'on fait agir sur les nitrates, nitrites et autres constituants du tabac une culture de micro-organismes pauvres en oxygène mais susceptibles d'une vie anaérobie avec dénitration et que l'on a amenés en milieu anaérobie à leur phase de croissance exponentielle, avec une solution nutritive appropriée à cette culture et ne contenant que peu d'oxygène accessible aux micro -organismes de cette culture, en appliquant des conditions anaérobies avantageuses pour les micro-organismes de cette culture, jusqu'à ce que les nitrates et nitrites soient dégradés et arrivent a la teneur résiduelle voulue, et qu'ensuite, on arrête l'action des micro-organismes. L'invention est plus particulièrement applicable dans le domaine du traitement du tabac avant transformation.The present invention relates to a process for improving tobacco by degrading the nitrates and nitrites it contains. Process characterized in that the nitrates, nitrites and other tobacco constituents are made to act on a culture of microorganisms poor in oxygen but capable of anaerobic life with denitration and which have been brought to their anaerobic environment. phase of exponential growth, with a nutrient solution suitable for this culture and containing only a little oxygen accessible to the micro-organisms of this culture, by applying anaerobic conditions advantageous for the micro-organisms of this culture, until nitrates and nitrites are degraded and arrive at the desired residual content, and then the action of microorganisms is stopped. The invention is more particularly applicable in the field of the treatment of tobacco before processing.
