Title (EN) SUGAR-ENRICHED EXTRACT DERIVED FROM TOBACCO
(FR) EXTRAIT ENRICHI EN SUCRE DÉRIVÉ DE TABAC
Abstract:
(EN) The present disclosure describes methods of obtaining and/or deriving a sugar-enriched extract from plants of the Nicotiana species and methods for incorporation of such extracts into various tobacco compositions. One exemplary method for preparing a sugar-enriched extract comprises contacting Nicotiana plant material with a solvent and extracting sugars into the solvent to form a liquid sugar-containing extract; separating a solid extracted plant material from the liquid sugar-containing extract; clarifying the liquid sugar-containing extract to form a clarified sugar-containing extract and a solids fraction; and isolating the liquid sugar-containing extract to provide a sugar-enriched extract comprising a combined weight of fructose and glucose of at least about 10% by dry weight. In certain embodiments, the sugars of the extract comprise at least about 50% by weight fructose.
(FR) La présente invention concerne des procédés d'obtention et/ou de fourniture d'un extrait enrichi en sucre provenant de plantes de l'espèce Nicotiana, et des procédés pour incorporer de tels extraits dans diverses compositions de tabac. Un procédé à titre d'exemple pour préparer un extrait enrichi en sucre comprend la mise en contact d'une matière végétale de Nicotiana avec un solvant et l'extraction de sucres dans le solvant pour former un extrait contenant du sucre liquide; la séparation d'une matière végétale extraite solide de l'extrait contenant du sucre liquide; la clarification de l'extrait contenant du sucre liquide pour former un extrait contenant du sucre clarifié et une fraction de solides; et l'isolement de l'extrait contenant du sucre liquide pour créer un extrait enrichi en sucre comprenant un poids combiné de fructose et de glucose d'au moins environ 10 % en poids sec. Dans certains modes de réalisation, les sucres de l'extrait comprennent au moins environ 50 % en poids de fructose.
