Description

Cigarette blasting bead coated with water-soluble essence and preparation method thereof

Technical Field

The invention belongs to the field of tobacco, and particularly relates to a tobacco blasting bead coated with water-soluble essence and a preparation method thereof.

Background

The addition of the bead blasting at the filter tip of the cigarette can increase the fragrance of the tobacco, the smoking experience and the taste. Generally, the commercial contents of the popping beads generally use caprylic capric triglyceride as a core material substrate, the taste of the popping beads is blended by adding different oil-soluble essences, and polysaccharide materials (animal gelatin, sodium alginate, carrageenan and the like) are used as wall materials to realize sealing, so that the oil-soluble essence packages with different fragrances are charged and sealed. However, the water-swelling property of polysaccharide materials limits the use of water-soluble essence as an additional fragrance of the popping beads.

In order to expand the application of water-soluble essence in the blasting beads, the current method and approach for coating water-soluble essence are mainly as follows: (1) single-layer structure: a) carrying out reverse phase emulsification on the core solution to form a water-in-oil type microemulsion, and taking biomass gum or synthetic resin as a wall material; b) the water-insoluble high polymer and the monomer thereof are polymerized into the negative core solution of the film package by the initiation of free radicals. c) The wall material is a complex of wax, long-chain lipid material and reinforcing material. (2) Double skin layer structure: a) namely, the inner layer is wax, and the outer layer is photosensitive resin material; b) the inner layer is a hydrophobic hot melt adhesive film, and the outer layer is biomass glue. (3) Three-layer structure: the inner layer is a wax layer, the middle layer is a coating powder layer, and the outer layer is a hydrophilic film layer.

In the above method and approach, the core liquid microemulsion in the monolayer structure has a hidden trouble of stability. The wax layer in the double-layer structure has poor adhesive force with the photosensitive resin, and is difficult to uniformly coat the surface of the wax layer; the hydrophobic hot melt adhesive film generally has better vapor permeability, and water molecules in the core liquid are easy to volatilize from the inside through the hot melt adhesive film, so that the biomass glue on the outer layer is softened and loses efficacy. The process design flow in the three-layer structure is complex, and the implementation difficulty is high. Therefore, the field needs to develop a bead for cigarette with simple preparation process, stable structure and good sealing performance.
