Casing flavor for reconstituted tobacco leaves produced by using paper-making method

The invention relates to tobacco flavors, in particular to a casing flavor for reconstituted tobacco leave produced by using a paper-making method. The casing flavor is prepared by mixing the following raw material components according to weight percentage: 8-15 percent of cured tobacco extracts, 2-3 percent of yellow sun-cured tobacco extracts, 2-6 percent of red date extracts, 1-4 percent of reed root extracts, 2-8 percent of momordica grosvenori extracts, 3-8 percent of tamarind pulp extracts, 6-8 percent of plum extracts, 5-7 percent of wild jujube leaves extracts, 8-10 percent of elm bark extracts, 8-10 percent of water and 21-55 percent of propanediol. The invention overcomes the defects of insufficient fragrance quantity, denser wood miscellaneous gas, larger stimulation, remained sour and hot feeling and certain burning feeling of the reconstituted tobacco leaves produced by using the paper-making method. The casing flavor increases fragrance quantity, enriches fragrance, ensures better softness and fineness, smaller stimulation to the throat part and less residues, ensures that a firing sense basically disappears, and greatly improves the organoleptic quality of the reconstituted tobacco leaves by using the paper-making method.
