Description
Technical field
The present invention relates to Field of Tobacco, particularly relating to humectant for improving expanded cut tobacco physics humid keeping performance and preparation method thereof.
Technical background
Expanded cut tobacco is through the pipe tobacco after expansion technique process, the history that existing more than 40 year uses in tobacco business, and what be wherein most widely used is the expanded cut tobacco adopting dry ice (carbon dioxide) expansion technique to produce.Dry-ice expanding technology uses carbon dioxide to flood tobacco leaf cells under certain pressure conditions, then allow through dipping after pipe tobacco rapid expanding in high temperature gas flow, again pipe tobacco is cooled, its moisture is returned to can meet the level that processing technology requires.The raw material of expanded cut tobacco can adopt flue-cured tobacco or burley tobaccos, and some in particular cases can also use Turkish tobaccos.
The humid keeping performance of tobacco and the physical structural characteristic of himself and chemical composition also exist close ties.The hydrophilic matrixes such as polysaccharide a large amount of in tobacco, pectin and inorganic ions are that moisture absorption provides good material base, grease between tobacco leaf cutin and wax etc. are for preventing moisture loss from providing barrier, the loose structure of tobacco also provides larger space for the absorption of moisture, but this structure be also tobacco in low moisture environments moisture scatter and disappear very fast.Expanded cut tobacco due to exaggerated conditions relatively violent, the structure of self has been subjected to certain destruction, and chemical composition also there occurs certain change, cause the exchange capacity of expanded cut tobacco and moisture more weak, humid keeping performance is poor, and in low moisture environments, dehydration is very fast, absorbs water slower in high humidity environment.
