Abstract
The application discloses a perfume load material and applications thereof. In the present application, the loading material is obtained by attaching a porous adsorption material to the surface of the fragrancing thread. The porous adsorption material has the advantages that the porous adsorption material has the inherent adsorption function, so that the spice is continuously enriched at the interface formed by the juncture of the spice and the loading material, the enrichment action is utilized to generate the power for promoting the spice to continuously diffuse and permeate into the aroma-increasing line, and the absorption degree of the essence in the aroma-increasing line is improved. Thereby increasing the loading effect.
Description
Technical Field
The invention relates to the technical field of essences, in particular to a loading material of a spice and application thereof.
Background
Proper amount of flavor raw materials are often required to be added into tobacco shreds in cigarette products, which is beneficial to improving the smoking quality of cigarettes. The raw flavor may be added directly to the tobacco shreds, or may be loaded on a suitable carrier and added to a desired position such as a filter tip, tobacco shreds, or cigarette paper of a cigarette.
There are many reports in the known art disclosing perfume loading materials. For example, the chinese patent CN109527642A discloses a method for preparing a fragrant thread with characteristic aroma of luo han guo. The preparation method comprises the following steps; the method comprises the following steps: preparing fructus momordicae essential oil for later use; step two: preparing fructus momordicae extract for later use; step three: adding the momordica grosvenori essential oil and the momordica grosvenori extract prepared in the first step and the second step into an ethanol water solution for dilution to prepare momordica grosvenori fragrant liquid for later use; step four: and (4) soaking cotton threads made of plant short fibers in the momordica grosvenori fragrant liquid prepared in the third step, taking out the soaked cotton threads and air-drying the cotton threads to obtain the fragrant threads with the characteristic fragrance of momordica grosvenori. The aromatic line with the characteristic aroma of the momordica grosvenori is used for the cigarette filter stick, so that the sweet feeling of the cigarette can be obviously increased, the smoke is softer and finer, the smoking comfort level of the cigarette is increased, the irritation of the cigarette is reduced, the aroma amount is increased, the aftertaste is clean, the scorched aroma and the dry feeling of the cigarette are reduced, the aftertaste is sweet, the characteristic aroma of the momordica grosvenori can be obviously highlighted, and the sensory quality of the cigarette is improved.
In the above prior art, the amount of the fragrance raw material directly absorbed by the flavoring thread as cotton thread is very limited for the fragrance raw material with insignificant fragrance characteristics, and it is difficult for the consumer to feel a characteristic fragrance sufficiently noticeable in smoking after it is added to the cigarette.
Disclosure of Invention
In view of this, the present application provides a loading material of perfume and an application thereof, which can effectively improve the loading effect of perfume.
According to the level of knowledge generally known to the person skilled in the art, the loading effect of a flavoring thread as loading material is limited by the influence of the flavoring thread on the absorption capacity of the perfume. The absorption capacity of the aroma-increasing line is in positive correlation with the surface wettability and the capillary action of the aroma-increasing line. The surface wettability is positively correlated to the hydrophilicity and lipophilicity of the surface, with greater hydrophilicity and greater lipophilicity simultaneously resulting in greater surface wettability. The capillarity of the flavoring thread has a remarkable influence on the fiber length inside the flavoring thread, the pore size between fibers and the hydrophile lipophilicity of the fibers.
Based on this known principle, to increase the loading effect of the fragrancing thread, effective means usually focus on the improvement of the intrinsic properties of the fragrancing thread itself to vary its intrinsic absorption capacity, for example to optimize the type of fibrous material of the fragrancing thread; or, adjusting the fiber organization mode of the flavoring thread, such as changing the winding tightness or the interweaving tightness of the fiber; alternatively, the surface of the fragranced thread may be surface-modified in order to increase its lipophilicity.
However, the present inventors have abandoned the above improvements in the prior art. It has been found that the prior art, which is dedicated to the modification of the intrinsic absorption capacity of the fragrancing thread, does not substantially modify the intrinsic mechanism of loading the fragrance thread with fragrance, i.e. the loading principle of the fragrancing thread with fragrance is entirely dependent on the penetration of the fragrance into the interior of the fragrancing thread. The inventors have surprisingly found that the maximum resistance causing such a maximum increase in permeation is due to the breaking of the bottleneck of "enrichment" of the perfume at the perfuming line and at the two-phase interface formed by the perfume, i.e. the driving force of "enrichment" in the prior art is due to the difference in concentration of the perfume inside the perfuming line, which is smaller as the perfume is increasingly deeply absorbed by the perfuming line, causing the concentration of the perfume at the two-phase interface to tend to stop.
The present inventors have not found a reliable means for finding this dilemma for a considerable period of time, despite the discovery of this fundamental dilemma of the prior art. It was later discovered, inadvertently, that the physisorption of porous materials could provide a more powerful engine for the implementation of the above enrichment. Unlike the concentration differences of the prior art, the physical adsorption of the fragrance by the porous material is significantly faster than the diffusion of the fragrance inside the fragrancing line, so that the fragrance is accumulated in large quantities at the interface between the two phases, which intensifies the concentration difference between the inside and outside of the fragrance. For example, the physical adsorption of the fragrance by the porous material is equivalent to the formation of a "reservoir" at the interface of the two phases, the resulting potential energy of the water providing another driving force for the expulsion of the water. The invention was created in view of the above-mentioned findings of interdependence and interrelation of the porous material and the fragrancing thread.
1. Definition of terms
As used herein, "flavoring thread" refers to a flavoring technology by which a flavoring (or essence) for a smoking article is impregnated or coated or otherwise absorbed for addition to the smoking article. The technology is well known, and reference can be made to chinese patents CN202680464U and CN202697698U, or a meeting paper "flavoring amount and centrality control technology of filter stick adding flavor thread, academic annual meeting corpus in 2006 of the chinese tobacco institute" and the like.
As used herein, "porous adsorbent material" refers to an adsorbent material having a porous or microporous shape, with pore sizes ranging from micron-sized to nanometer-sized, and the like, without limitation to physical adsorption.
As used herein, "extrusion molding" is also known as extrusion in plastic processing, and extrusion using hydraulic press pressure on the die itself in non-rubber extruder processing is called extrusion. The method is a processing method for manufacturing various cross-section products or semi-products by continuously passing materials through a machine head while being heated and plasticized and being pushed forward by a screw under the action of a charging barrel and the screw of an extruder.
2. Load bearing material
The loading material is provided with a flavoring line and a porous adsorption material attached to the surface of the flavoring line.
Here, the formation process of the adhesion may be exemplified by, but not limited to, coating, dipping, or extrusion molding, and the like. The adsorption on which the attachment depends may be physical adsorption or chemical adsorption.
The perfume is added to the surface of the porous adsorbent material.
3. Aroma-increasing line
Suitable but non-limiting specific examples of the kind of the fragranced thread are any form of molded body interwoven or intertwined with fibers, one or at least two of cotton thread, chemical fiber thread. In view of wider compatibility with the type of the porous adsorbent, cotton thread is more preferable.
Suitable but non-limiting specific examples of thread diameters for the fragranced thread are thread diameters of 0.1mm to 1.5mm, such as 0.1mm, 0.15mm, 0.2mm, 0.4mm, 0.5mm, 0.8mm, 1mm, 1.2mm, 1.3mm, 1.4mm, 1.5 mm. If the thread diameter is too long or too short, the processing effect of the porous adsorbent material adhering to the surface of the aroma-enhancing thread, which will be described later, is affected.
A suitable but non-limiting specific example of a breaking strength for the fragrancing thread is a breaking strength of not less than 30 kg. If the breaking strength is too low, the processing effect described later is impaired.
4. Porous adsorbent material
A suitable but non-limiting specific example of a specific type of porous adsorbent material is any form of porous material. In consideration of the effect of adhesion to the flavor line, it is more preferably one or at least two of starch, cellulose, polylactic acid, polypropylene, polyethylene glycol, polyvinyl alcohol, and polyvinyl acetate.
A specific example of a suitable but non-limiting specific surface size for the porous adsorbent material is 300m2/g~800m2G, e.g. 300m2/g、320m2/g、350m2/g、400m2/g、500m2/g、550m2/g、 600m2/g、700m2/g、750m2G or 800m2And/g, etc.
5. Preparation of Supported Material
The supporting effect of the supporting material of the present application is not particularly limited to a specific production method. And the preparation process of the load material is very easy to deduce by the person skilled in the art from the composition of the load material and the general knowledge.
However, for the purpose of adhesion strength and efficiency of adhesion of the porous adsorbent material, suitable but non-limiting examples of preparation methods can be cited, such as:
extruding and molding fluid containing porous adsorption materials on the surface of the aroma-increasing line to obtain a complex;
the composite is first placed under pressure and then under atmospheric pressure to allow it to expand.
The above-mentioned implementation of the fluid of the porous adsorbent material is easily conceived by putting the porous adsorbent material solvent in a solvent that can be derived according to the solubility and polarity of the porous material, such as water, ethanol, propylene glycol, etc. Of course, without being limited to dissolution, surfactants conventional in the food field may also be added to improve the dispersibility thereof. The amount of the solvent to be used can be adjusted in general in accordance with the actual addition in the actual extrusion.
Here, the pressure under the pressurization condition is preferably 2 to 5MPa, for example, 2 MPa, 2.5MPa, 3MPa, 3.5MPa, 4MPa, 4.5MPa or 5 MPa; the temperature of the pressurizing condition is 110-130 ℃, such as 110 ℃, 115 ℃, 120 ℃, 125 ℃ or 130 ℃; the holding time under the pressurizing condition is 5-15 min, such as 5min, 6min, 8min, 10min, 12min, 15min, etc.
Here, the heating temperature for the extrusion molding is 50 to 220 ℃, for example, 50 ℃, 55 ℃, 60 ℃, 70 ℃, 80 ℃, 100 ℃, 130 ℃, 150 ℃, 180 ℃, 200 ℃, 210 ℃, 220 ℃ and the like.
The rotation speed of an extrusion screw of the equipment for carrying out extrusion molding is 100r/min to 350r/min and the like within the heating temperature range of the extrusion molding.
The "puffing" referred to above is understood to be the mechanism whereby the operation under pressurized conditions followed by the normal pressure conditions provides a perfect sudden depressurization in which the internal pressure of the material is higher than the external pressure and the material expands outwards, so that the inherent porosity of the material itself increases. Pore formers conventional in the art may also be added to the flow of porous adsorbent material in order to enhance the expansion effect.
It should be noted that the fragrancing thread may also be surface-modified in order to improve the adhesion of the porous absorbent material to the fragrancing thread. For example, a dispersion obtained by dispersing a siloxane coupling agent in a solvent such as ethanol, methanol and the like (adding a pH regulator such as ammonia water and the like if necessary) is adopted, the aroma-increasing line is soaked by the dispersion and then dried, the soaking temperature can be about room temperature, and the soaking time can be 4-12 hours. The temperature for drying is preferably not more than 80 ℃.
At the same time, the impregnation solution of the siloxane coupling agent prevents the fragrancing thread from being deformed during the above-mentioned preparation process.
6. Use of support materials
Adding the flavor line obtained by loading the flavor on the loading material into a cigarette product.
Here, the most widespread place of addition to smoking articles is generally the filter. In addition to this, there may be wrapping paper or the like that wraps tobacco segments of tobacco or cut tobacco. The position of the perfume added to the cigarette product does not cause any damage to the loading effect, and is considered according to actual factors such as actual needs and volatilization difficulty of the fragrance of the perfume.
As for the kind of the essence, there are conventional tobacco essences such as menthol and the like.
