The invention discloses a method for preparing pearl-powder composite porous starch crystalline particles and the application of the pearl-powder composite porous starch crystalline particles to the cigarette filtering tip. The method comprises the following steps: mixing pearl powder and porous corn starch uniformly according to a certain proportion, moistening by deionized water, granulating, shaping by microwave, drying by microwave, and sieving to obtain the pearl-powder composite porous starch crystalline particles with high strength. The pearl-powder composite porous starch crystalline particles can be added into the cigarette filtering stick to prepare the ternary composite cigarette filtering stick, can reduce the content of benzo [a] pyrene, phenol, tar and other harmful components in the smoke and can increase the content of amino acids and other nutritional components in the smoke. The sensory cigarette smoking evaluation shows that the pearl-powder composite porous starch crystalline particles can be added to the cigarette filtering stick to reduce the smoke irritation and improve the cigarette smoking quality.

The invention discloses a preparation method of preformed water-wrapped popcorn for cigarettes, and aims to provide a preparation method of preformed water-wrapped poppies for cigarettes which is convenient for processing. The specific preparation steps of the preparation method are as follows: (1) firstly produce hollow spherical plastic beads by means of plastic thermoplastic; (2) inject water into the hollow spherical plastic beads, and apply hot melt adhesive at the injection port of the hollow spherical plastic beads ;When the injection is completed, scrape the hot melt adhesive with a scraper, and seal the injection port of the hot melt adhesive to play a sealing role; (3) Put the sealed spherical particles into the hot air rotary oven; the spherical particles in the hot air rotary oven The hot melt adhesive on the particles will soften again, and the surface will be homogenized by rolling and rubbing against each other, forming spherical water-encapsulated beads with good regularity. The present invention can be added to the cigarette filter tip through the way of adding conventional explosive beads. When smoking the cigarette, the consumer can release the water in the popping beads by squeezing the popping beads, thereby playing the role of hydrating the smoke.
