| Abstract：In order to prepare the perfume-loaded gel beads of polyethylene glycol composite with coffee flavor, the optimal process was determined, and then the feasibility of the application of gel beads in cigarette filter rods was verified. The preparation was carried out by dropping method. The preparation process was optimized by single factor experiment and orthogonal experiment, and the slow-release performance and stability of gel beads were investigated. The cigarette filter rods with gel beads were prepared by filter rod molding machine, and the physical indexes of the filter rods were investigated. The results showed that the optimal preparation process of fragrant gel beads was as followings: PEG6000 was used as the matrix, the ratio of matrix to spice was 3:1, the dimethyl silicone oil (50 cs) at 15 °C was used as the coolant, the dropping temperature was 70 ℃, the dropping speed was (75±5) particles/min, and the dropping distance was 8 cm. The coffee fragrant gel beads based on polyethylene glycol could be stably prepared, and the gel beads had good slow-release performance and stability. The average length of filter rod with gel beads was 120.09 mm, the average circumference was 24.28 mm, the average roundness was 0.27 mm, the average pressure drop was 3 184 Pa, and the average hardness was 87.94%. The filter rod with gel beads met the design requirements. The gel beads had the feasibility of application in tobacco filter rods. |
