Description
Technical Field
The invention relates to the field of tobacco essence and flavor, in particular to a cigarette filter rod containing double solid aromatic bead particles and a preparation method thereof.
Background
In the tobacco industry, the cigarette stereoscopic flavor blending technology is developed rapidly, and particularly, a new method and a new technology in a cigarette filter rod are developed, wherein the new technology comprises cigarette blasting beads, microcapsules, nano particles, powdery particles and the like. At present, through the inspection of consumer market, the overall acceptance of the cigarette bead blasting is better, and the invention patent with the application number of 201710285349.8 discloses a raspberry essence for the cigarette bead blasting and the application thereof in cigarettes, wherein the raspberry essence is prepared by compounding a raspberry extract and a solvent of caprylic capric acid glyceride (ODO) and then is wrapped in the bead blasting, and when the cigarettes are smoked, the aroma can be released by pinching the bead blasting arranged in a filter rod; for another example, CN201520383002.3 discloses a cigarette filter rod capable of reducing tar and increasing flavor, which comprises an acetate fiber filter rod, an activated carbon composite filter rod and a piece of wrapping paper outside the two sections of filter rods, wherein the activated carbon composite filter rod is arranged at one end of the acetate fiber filter rod, which is in butt joint with a cigarette, a hollow cavity is arranged at the central part of the activated carbon composite filter rod, an activated carbon filling layer and one or more first flavor beads are arranged in the hollow cavity, and one or more second flavor beads are embedded in the acetate fiber filter rod; the first flavor bead and the second flavor bead contain different flavors, and the first flavor bead is a flavor bead which contains vanilla flavor liquid and can be broken by a consumer to permeate flavor; the second spice beads are spice beads which contain mint spice liquid and can be broken by a consumer to permeate fragrance. However, the addition of the cigarette popping beads and dropping pills has certain disadvantages, including low forming rate, high cost, the need of adding a solvent (the popping beads which can make up the deficiency of cigarette fragrance and moist feeling of cigarettes and the preparation method thereof, application number 201610564325.1) and the like, and the solvents of the popping beads and dropping pills, such as olive oil, ODO and the like, have trace unpleasant odor, so that the popping beads are mainly used for wrapping essence and spices with strong fragrance, such as ginseng, mint and the like. In addition, the patent of Shanghai Polyhua technology GmbH "Zeolite flavor bead-containing cigarette filter rod and cigarette Zeolite flavor bead preparation method" (application No. 201710990114.9) adopts a plurality of zeolite fine particles as flavor adsorption carriers and places the zeolite fine particles in the cigarette filter rod in a cavity form, the method can play a certain flavor slow release effect, but the fine additives such as nano particles, powdery particles and the like easily cause the smoking safety worry of consumers, so the popularization is not ideal. CN201010297374.6 discloses a tar-reducing and flavor-enhancing method for a cigarette filter stick and application thereof, and particularly discloses a method for preparing a multi-element composite filter stick, wherein the filter stick comprises a filter element, the filter element adopts a composite filter element, a cavity section is arranged between every two sections of acetate fiber filter element sections to improve the filtering treatment effect, but edible essence is uniformly sprayed on a piece of forming paper, and the traditional mode is adopted in the aspects of enhancing flavor and maintaining moisture.
As an important special research in the industry for years, the tobacco flavor enhancement and moisture retention have good solubility, while the moisture retention essence is mostly natural plant extracts such as flavonoids and the like, so the solubility is poor, and the two types of essences are simultaneously placed in one bead blasting or dropping pill to have certain disadvantages, insoluble substances are easy to separate out and precipitate, and the like. In addition, when the cigarette is flavored, the problem that the efficacy of the two essences with the flavoring property and the moisture retention property is 1+1<2 is often found. If two blasting beads are adopted for respectively wrapping, the effect is not ideal in consideration of the liquidity of the liquid.
The solid aromatic bead is prepared from the natural china clay raw materials such as white carbon black and sodium silicate, and the white carbon black is used as an environment-friendly auxiliary agent with excellent performance, is nontoxic and tasteless, and can be used in the food industry. White carbon black is a general term for white powdery X-ray amorphous silicic acid and silicate products, mainly referring to precipitated silica, fumed silica and ultrafine silica gel, and also including powdery synthetic aluminum silicate, calcium silicate, and the like. The white carbon black is porous material, and its composition can be SiO2•nH2O represents, wherein nH2O is present in the form of surface hydroxyl groups. The white carbon black is high temperature resistant, non-combustible, tasteless and odorless and has good electrical insulation.
Compared with the cigarette filter rod added with the microcapsule and the powdery particles, the cigarette filter rod has the advantages that the solid fragrant bead form is adopted, so that the worry of the consumers about the safe smoking of fine additives such as charcoal powder, silica gel powder, zeolite powder, cyclodextrin particles and the like can be avoided; in addition, the preparation process of the aromatic bead is simple, the qualification rate and the production stability are better compared with the cigarette filter rod added with the exploded bead, no additional solvent is needed during the aroma attachment, and the aroma is purer.

Therefore, in the preparation process of the fragrant bead, the white carbon black, the sodium silicate, the PVA, the liquid paraffin and the distilled water are mixed according to the ratio of 100: 20: 10: 1: uniformly mixing 800 parts by mass, adding into a grinder, and grinding the slurry by the slurry grinder according to a ball material ratio of 5: 1 grinding for 4 hours, and calcining the bead-shaped blank at 1200 ℃ for 3 hours with the best effect.
The present invention also performs SEM scanning on the beads of example 4, which is most effective in application, to confirm the composite adsorption effect of the porous structure thereof, as shown in fig. 2, 3 and 4.
The above embodiments are merely preferred embodiments of the present invention, and any simple modification, modification and substitution changes made to the above embodiments according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
