Abstract
Tobacco stem and tobacco dust made reconstituted tobacco paper-base with a paper-making method, effect of extracted and refined on tobacco stem and tobacco dust, particular effect of tobacco stem and tobacco dust ratio on physical properties, chemical composition and microstructure of reconstituted tobacco paper-base were studied. The results indicated that the content of water soluble sugars, total alkaloid, chloride, total nitrogen of the extracted tobacco stem and extracted tobacco dust were decreased, content of holocellulose was increased. With decreasing of tobacco stem pulp ratio (increasing of tobacco dust pulp ratio) of reconstituted tobacco paper-base, there was rapid decrease in tensile index, tear index, bulk and air permeability of reconstituted tobacco paper-base. The scanning electron microscopy (SEM) showed that tobacco dust ratio more than 30%, bulk of reconstituted tobacco paper-base decreased significantly. Content of water soluble sugar, total alkaloid, chloride and total nitrogen of tobacco reconstituted paper-base decreasing significantly after paper-making.
