The invention discloses a preparation method of large-particle solid aromatic beads for cigarette filter tips. The preparation method comprises the following steps: (1) dissolving chitosan in an acetic acid solution, adding polyvinylpyrrolidone, then slowly dropwise adding an ethanol solution containing citral and ethyl cellulose, stirring, filtering out a liquid, soaking with an acetic acid solution, washing with water, and carrying out vacuum drying to obtain a copolymer; (2) adding the tobacco flavor into a Tween 80 water solution, and emulsifying to obtain an emulsion; (3) dissolving the copolymer in an acetic acid solution, slowly adding the emulsion, stirring, and carrying out rotary evaporation on the excess solvent to obtain particles; (4) mixing, stirring and granulating the particulate matters, porous starch and a hydroxypropyl methylcellulose solution. According to the present invention, aromatic beads prepared through the method are strong in adsorption capacity, and can effectively adsorb perfume components. Meanwhile, aromatic beads prepared through the method have the lasting and stable interception effect on the harmful flue gas, and any unsafe exogenous component during the preparation process is not introduced at all. Moreover, no harmful substance residue exists after the preparation process, so that the method is safe to use.
