Preparing and application of natural product powder composite particle with aroma enhancement effect in cigarette filter

The invention discloses preparing and application of natural product powder composite particles with the aroma enhancement effect in a cigarette filter. 8-30 parts of ground coffee, 1.5-5 parts of sweetened natural plant powder, 0.3-1.5 parts of pearl powder and 100 parts of multi-hole corn starch are evenly mixed and moistened by deionized water comprising reducing sugar. Wet granulation, microwave shaping, microwave drying and sieving are carried out on the mixture and high-strength natural product powder composite multi-hole starch crystalline particles are obtained. The particles are added to cigarette filter rods to make binary or ternary composite filter rods, so that the content of nutrition components such as specific coffee volatile fatty acid and specific pearl powder amino acid can be added to smoke. It is indicated through cigarette sensory evaluation that the natural product powder composite particles added to the filter rods can boost the aroma amount of the smoke of cigarettes, improve aroma qu
