Description

Technical Field

[0001] The invention belongs to the technical field of cigarettes, and particularly relates to a cigarette water capsule and a preparation method and application thereof. Background Art

[0002] In traditional cigarette flavoring technology, the main method is to add flavoring liquid into tobacco. The liquid added in this way is often partially lost during the cigarette combustion process. At the same time, since the reaction of complex material systems under high temperatures is difficult to predict, some of the liquid will also produce some adverse sensory effects.

[0003] As an emerging flavoring method for cigarettes, popping beads flavoring can overcome the defects of existing flavoring methods to a certain extent. The main reason is that the popping beads contain flavorings. Before smoking the cigarette, consumers prefer to crush the popping beads contained in the filter rod and then burn the cigarette. At this time, the smoke passes through the filter tip and acts on the consumer together with the popping bead liquid, thus completing the flavoring and replenishing process. On the one hand, this method can effectively avoid the loss of flavor liquid during the combustion process of tobacco. On the other hand, since the flavoring is placed in the sealed popping beads, it will not be lost during the storage of cigarettes, thereby ensuring the stability of cigarette quality.

[0004] CN104305521A discloses a water bag with water and hydrophilic substances as core materials, and a method for preparing the water bag. The water bag uses long-chain ester materials and coagulant aids as wall materials, and is prepared by a sharp hole-coagulation bath method. The preparation process is greatly affected by the viscosity of the wall material, and the addition rate of the water bag in cigarettes is only 73-86%, which is not conducive to the subsequent processing of cigarette filter rods.

[0005] CN105559139A discloses a production system for hollow alginate capsules for cigarettes, which produces explosive beads by dropping a CaCl2 emulsion containing essential oil into a sodium alginate solution. As the amount of sodium alginate in the molding liquid of the cigarette capsules prepared by the invention is gradually consumed, the pressure on the finished capsules produced subsequently gradually decreases, and the quality stability of the cigarette capsules needs to be improved.

[0006] Therefore, how to provide a water capsule for cigarettes that has suitable anti-crushing pressure and soft smoke and has a simple preparation method has become a problem that needs to be solved urgently. Summary of the invention

[0172]

[0173]

[0174] It can be seen from the data in Table 2 that the water capsules for cigarettes provided by the present invention (Examples 1-16) can reduce the release of harmful gas components in smoke, among which the release of HCN is reduced by 27-43%, the release of phenol is reduced by 24-44%, the release of ammonia is reduced by 27-42%, the release of carbon monoxide is reduced by 18-33%, and the release of tar is reduced by 24-35%.

[0175] In the present invention, the release amount of harmful gases in smoke can be absorbed and neutralized by the mutual coordination between the components of the aqueous phase Chinese medicine extract concentrate, the mutual coordination between the components of the oil phase essence, and the mutual coordination between the components of the wall material; and the core liquid of the present invention adopts an oil-in-water emulsion, which can increase the absorption amount of harmful smoke in the aqueous phase or the oil phase.

[0176] By comparing Example 1 with Examples 4-10, it can be seen that the components in the Chinese medicine extract concentrate of the present invention cooperate with each other, synergistically enhance the effect, and jointly reduce the emission of harmful gases in flue gas.

[0177] By comparing Example 1 with Examples 11-13, it can be seen that the various components of the oil phase flavor cooperate with each other to absorb and neutralize harmful gases in the smoke.

[0178] By comparing Example 1 with Examples 14-16, it can be seen that sesbania gum and gelatin arabic cooperate with each other to block the emission of harmful gases in flue gas.

[0179] By comparing Example 1 with Comparative Examples 1-3, it can be seen that the components of the wax, cellulose and plant gum in the wall material cooperate with each other to block the release of harmful smoke.

[0180] By comparing Example 1 with Comparative Examples 4-6, it can be seen that the use of water-in-oil emulsion as the core liquid can reduce the release of harmful gases.
