(4) mixing the first tobacco extract and the second tobacco extract to obtain a tobacco recombinant;
(5) preparing a spice for cigar flavor cigarettes, wherein the spice for cigar flavor cigarettes comprises 1-10 parts of tobacco heavy component, 1-5 parts of cocoa extract, 0.01-0.05 part of sandalwood oil, 0.05-0.1 part of 2-methylvaleric acid and 0.001-0.005 part of isovaleric acid in parts by weight;
(6) adding cigar flavor tobacco flavor into pericarp particles of fruits of Citrus plants by vacuum flavoring method to obtain flavor-carrying particles;
(7) and adding the aroma-carrying particles as a filler into the paper pulp and making the paper with pulp to obtain the cigar flavor cigarette paper.
2. The preparation method of claim 1, wherein the second extraction in the step (3-1) is a leaching extraction method, and the extraction conditions are 60-80 ℃ for 0.5-3 h, and the ratio of materials to liquids is 1 (6-12).
3. The preparation method according to claim 1, wherein the step (4) is specifically as follows:
mixing the first tobacco extract and the second tobacco extract according to the mass ratio of 1 (10-20) to obtain the tobacco recombinant.
4. The method according to any one of claims 1 to 3, wherein step (6) is specifically as follows:
(6-1) preparing dried pericarp of fruit of Citrus plant into pericarp granule of 0.01-0.1 mm;
and (6-2) adding the cigar flavor tobacco flavor into the fruit peel particles by a vacuum flavoring method according to the mass ratio of the cigar flavor tobacco flavor to the fruit peel particles of (4-5):10 to prepare the flavor-carrying particles.
5. The method according to claim 4, wherein the step (6-2) is specifically as follows:
controlling the vacuum degree to be-0.08 MP to-0.06 MPa, controlling the rotating speed of a feeding peristaltic pump to be 140 rpm to 160 rpm, controlling the atomization pressure of high-pressure air to be 0.2MPa to 0.3MPa, and adding the cigar flavor tobacco flavor to the peel particles by a vacuum flavoring method according to the mass ratio of the cigar flavor tobacco flavor to the peel particles of (4-5):10 to prepare the flavor-carrying particles.
6. The preparation method according to claim 1, wherein the step (7) is specifically as follows:
according to the mass ratio of the aroma-carrying particles to the cigar flavor cigarette paper of (2-5):100, the aroma-carrying particles are added into the wood pulp fiber liquid, and after mixing, paper pulp suspension is formed and manufactured by paper making, thus obtaining the cigar flavor cigarette paper.
