Filter stick flavor enhancing tea particle and preparation method thereof

The invention discloses a filter stick flavor enhancing tea particle and a preparation method thereof. The preparation method for the filter stick flavor enhancing tea particle comprises the following steps of: smashing one or several of white tea, dark green tea, yellow tea, black tea, green tea, wulong tea, as well as waste tea dust and tea stems of the white tea, the dark green tea, the yellow tea, the black tea, the green tea, the wulong tea at the temperature of below 55DEG C; sieving to obtain fine powder of 120-200 meshes; adding aqueous solution of hydrophilic polymer binding agent into the obtained fine powder; evenly stirring to obtain an intermediate; pelletizing via a sieve of 20 meshes by a granulator; sieving to obtain particles of 20-60 meshes; and drying or carrying out air drying on the obtained particles at the temperature of 10-55DEG C until moisture is 6-14%. The tea particle consists of 97-99.5% of tea powder and 0.5-3% of hydrophilic polymer binding agent, and the hydrophilic polymer binding agent is cellulose ethers, natural polymer and derivants thereof or polypropylene-series synthetic polymers. The obtained particle has the advantages of good aroma keeping performance and big specific surface area. The particle is fully contacted with smoke to gradually elute particle surface tea aroma, and the internal tea aroma in the particle is gradually released to perform the action on enriching the cigarette aroma. Meanwhile, the particle post processability is good, the addition amount is easy to control, and the risk that the particle enters the mouth in a dust mode is eliminated.
