Description
Technical Field
The invention relates to the technical field of aroma-carrying particles for cigarettes, in particular to a slow-release aroma-carrying particle which takes a waxy material as a raw material and has a temperature phase change characteristic, and also relates to a preparation method and application thereof.
Background
In order to improve the quality of cigarettes and increase the fragrance of tobacco, the flavoring and casing technology is widely applied to the tobacco industry. Currently, cigarette auxiliary material aroma loading becomes an important research field, and material aroma loading comprises various aroma loading technologies such as shaping agent aroma loading in filter tow, dispersed aroma loading in filter tow, particle aroma loading, center line aroma loading, bead blasting aroma loading, shaping paper, aluminum foil paper aroma loading and the like.
The aroma-carrying particles are particles loaded with aroma added into the cigarette filter stick, and when mainstream smoke of cigarettes passes through the particles, aroma substances are released along with the particles, so that the aim of perfuming is fulfilled. Phase change materials are often used in prior art flavour-bearing particles in order to achieve long-term stability of the flavour in the particles during shelf life, while ensuring rapid release of the flavour as mainstream smoke passes through the particles.
One type is in the manufacture of aroma-carrying granules containing phase change materials using extrusion or granulation processes. The phase-change material in the particles is usually a gel material, for example, chinese patent application CN111759001A discloses cigarette flavoring slow-release gel particles and a preparation method thereof, polyethylene glycol-1000, polyethylene glycol-4000, lauric acid, octenyl succinate starch, tapioca starch, a humectant, an adhesive and a fragrant substance are used as raw materials, and the materials are melted, mixed uniformly and then freeze-dried to prepare the fragrance-carrying particles. For example, chinese patent application CN 112656024A discloses a method for preparing cooling and aroma-increasing granules for HNB cigarettes, which comprises mixing plant fiber-containing powder, a phase-change material, a pore-forming agent, a humectant, essence, and a swelling agent, then extruding, rounding, shot blasting, drying, and sieving to obtain granules, wherein the phase-change material is microcrystalline cellulose (MCC), PLA, PEG4000-8000, and the like.
The gel material is adopted as the phase-change material, and has the disadvantages that most of the gel materials belong to non-degradable materials and do not accord with the pursuit of the current environmental protection technology; on the other hand, the price of gel materials (such as glycol, microcrystalline cellulose and the like) is higher, so that the production cost is increased; in addition, the granules made of gel materials have the disadvantages of large fragrance loss, rapid fragrance-carrying capacity decay, and unstable fragrance release.
The other type is to adopt a dropping pill, a microcapsule or a coating process to prepare the aroma-carrying granules containing the phase-change material. For example, chinese patent application CN 114011329A discloses a method for preparing water particles capable of increasing smoke moistening feeling, which comprises the steps of uniformly mixing water, polyethylene glycol, an adhesive and a structure reinforcing agent under the heating condition, and preparing the mixture into water dropping pills by a dropping pill machine. For example, chinese patent application CN 114766718A discloses a cigarette flavor-carrying particle, which has a double-layer structure, wherein the inner layer is a flavor-carrying granular core material, the outer layer is a shell made of a waxy coating material, and a coating solution containing the waxy material is uniformly sprayed on the surface of the granular flavor-carrying material by a coating machine. For another example, the chinese patent application CN 113749290A discloses a cooling and flavoring microcapsule, which comprises a wall material and contents, wherein the wall material comprises polypropylene carbonate and polybutylene carbonate, and the contents are nicotine, essence material for cigarette or natural extract, and the like, and are obtained by a microcapsule preparation process.
Among them, the dripping pill has a disadvantage of small amount of fragrance, so that it is necessary to use a high addition amount in order to secure the content of the fragrant substance. In addition, the production process of the dripping pills, particularly the dripping pills, leads the granules to be easy to be bonded and hardened, and influences the application of the granules in the downstream processing process. The granule obtained by microencapsulation or coating process has the disadvantages of thin coating layer, weak ability of blocking the aroma substances, and small aroma-carrying amount because the gel component in the microcapsule does not participate in aroma carrying. The dropping pill and the microcapsule have a common defect, and because the surface layer material (coating layer or microcapsule material) does not contain fragrant substances, the dropping pill or the microcapsule particle has poor release stability before and after releasing essence, and the situations of less early release amount and more later release amount generally exist. In addition, the microcapsule granule has multiple manufacturing procedures, long production and processing time and low production efficiency.
From the prior art, although the aroma-carrying particles have the advantages of simple equipment and process, low requirement on the character of aroma substances and the like, the aroma-carrying particles have the defects of easy volatilization after the aroma substances are attached, unstable aroma release, short aroma-carrying time and the like.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and develop a flavor-carrying particle which has simple equipment and process, can stably store flavor substances in the particle for a long time and can quickly and stably release the flavor substances when mainstream smoke passes through.
The idea of the invention is to select a safe wax material suitable for making cigarette particles as a phase-change material, and obtain the aroma-carrying particles by an improved granulation technology.
Based on the above, the invention provides a preparation method of waxy phase-change slow-release aroma-carrying particles, which comprises the following steps:
(1) Mixing of materials
Weighing 10-40 parts of soybean wax, 0-10 parts of stabilizer, 50-80 parts of starch, 10-30 parts of plant-based powder raw materials and 0-40 parts of essence and spice for tobacco according to parts by weight, heating and stirring in a water bath at 60-100 ℃ until the raw materials are uniformly mixed to obtain a mixed material;
the stabilizer is cyclodextrin, carrageenan or xanthan gum; the plant-based powder raw material is a powder raw material obtained by crushing dried plant stems, leaves, flowers or fruits to 80 meshes;
(2) Granulating
And placing the obtained mixed material in a granulator, granulating at 60-70 ℃, cooling to normal temperature after granulation, and then sieving by a 20-50 mesh sieve to obtain the wax phase-change slow-release aroma-carrying granules.
In the present invention, the starch is tapioca starch or corn starch, porous starch or sweet potato powder. These starches are commercially available products.
Preferably, the plant-based powdered raw material is vanilla powder, phyllanthus emblica powder, coffee powder, strawberry powder, pueraria powder or momordica grosvenori powder. The plant-based powder raw materials can be purchased and obtained products, and can also be prepared by taking roots, stems, leaves or flowers of plants as raw materials, drying and crushing the raw materials.
Powders such as phyllanthus emblica, coffee powder and the like are common powders in tobacco granules and have been widely used in commercial granule manufacturing. The application of the radix puerariae powder and the phyllanthus emblica powder in the tobacco particles has the function of improving the smoke smoothness. The momordica grosvenori can also promote the secretion of saliva or body fluid in the smoke, increase the sweet taste in the smoke, and the coffee powder, the vanilla powder and the strawberry powder have unique aroma characteristics and have the effect of increasing the richness of the aroma of cigarettes in the tobacco particles.
Generally, plant powders with a fineness greater than 80 mesh and having a fragrance can be used to make the fragrance-loaded particles of the present invention.
In the present invention, the melting point of the soybean wax is 45 to 52 ℃.
According to an alternative embodiment, the tobacco flavor is selected, for example, from strawberry flavor, greengage extract, vanilla flavor, blueberry flavor or lemon flavor.
In the present invention, granules having a particle size of 10 to 70 mesh are produced by conventional processes such as extrusion spheronization granulation, spray and dispersion mist granulation, and swing granulation.
Based on the above, the invention also provides application of the waxy phase-change slow-release aroma-carrying particles obtained by the preparation method in cigarette filter sticks.
Preferably, the dosage of the waxy phase-change slow-release aroma-carrying particles in the cigarette filter stick is 10-200mg per cigarette.
Compared with the prior art, for example, polyethylene glycol is used as a phase change material to prepare traditional particles, the raw materials in the preparation process need to be added with water for stirring, and the particles obtained after granulation are wet particles, so that a separate drying step is required (the step usually needs longer time and consumes more energy), and the two steps greatly increase the operation complexity for a production line. The flavor-carrying particles made of the soybean wax are stirred without adding water, the materials are ensured to be in a liquid state only by heating in the mixing and granulating processes, and the particles can be solidified and molded to obtain particle products after natural cooling after granulation, so that an additional drying link is not needed, the process is greatly simplified, and the manufacturing time is effectively shortened.
