The invention relates to the technical field of heat-not-burn cigarettes, in particular to a method for treating tobacco
powder of a heating cigarette. The method comprises the following steps: addingtobacco
powder into an
ethanol solution, and carrying out heating
reflux to obtain filter residues and an
ethanol leaching solution; mixing the filter residues with
silicon carbide and
pectin, and adding the mixture into water to obtain a
system a; dropwise adding a
calcium chloride solution into the
system a, stirring for 50-70 minutes, and removing water to obtain modified filter residues; andapplying the
ethanol leach liquor to the modified filter residues, and
drying to obtain the treated tobacco
powder. On one hand,
calcium chloride and
pectin are cross-linked to form gel, so that the
mechanical strength of
silicon carbide combined on tobacco powder is improved; on the other hand,
calcium chloride occupies a
silicon carbide network, and calcium chloride is removed by utilizing an ethanol leaching solution to form micropores, so that not only is the
bonding strength of tobacco active ingredients backfilled into tobacco powder improved, but also the
smoke circulation performance can be improved through the micropores, and the
smoke generation amount and the
smoke generation fragrance are improved.
