BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to more clearly illustrate the scheme of the present application, a brief introduction is given below to the drawings required for use in the description of the embodiments. Obviously, the drawings described below are some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0040] Figure 1 The present invention is a flow chart of a method for preparing a guarana composition according to an embodiment of the present application. DETAILED DESCRIPTION

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0042] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0043] To solve the above technical problems, please refer to Figure 1 The present application example provides a method for preparing a guarana composition, which adopts the following technical solution:

[0044] S100, providing a guarana extract, and crushing the guarana extract to form a guarana powder;

[0045] S200, providing a diluent, a flavoring agent and a fragrance, and uniformly mixing the guarana powder, the diluent, the flavoring agent and the fragrance to obtain a first mixture;

[0046] S300, providing a wetting agent, and uniformly mixing the first mixture and the wetting agent to obtain a second mixture;

[0047] S400, drying the second mixture;

[0048] S500, performing shaping treatment on the second mixture to obtain a guarana composition.

[0049] In this embodiment, the guarana extract is crushed to form guarana powder, which can make the guarana extract (powdered) in the first mixture evenly distributed, and can also make the diluent, flavoring agent and fragrance agent mixed with the guarana powder more efficient. The fragrance agent can make the guarana composition have a preset fragrance, and the flavoring agent can adjust the final taste of the guarana composition, which plays a role in modifying the taste of the guarana composition. The lubricant can make the first mixture (dispersed) form the second mixture (soft material), thereby making the second mixture able to be shaped after drying, and then forming a guarana composition with a solid form.

[0050] The diluent can be used to adjust the amount of flavoring agent, flavoring agent, wetting agent, and guarana powder. If the amount of guarana powder needs to be increased, it can be achieved by reducing the diluent. If the amount of guarana powder needs to be reduced, it can be achieved by increasing the diluent, so that the sum of the amount of the pre-prepared guarana powder, diluent, flavoring agent, flavoring agent, wetting agent, and diluent is 100, ensuring that the formula of the preparation method can be used for production. Guarana extract contains vitamins and caffeine with a maximum content of 22%, so it can slowly and long-term stimulate human nerves and play a refreshing effect, and the stimulation is relatively mild and harmless to the human body.

[0051] In summary, the preparation method of this embodiment can prepare a guarana composition in a solid form, which is easy to carry and can be quickly taken orally. At the same time, the guarana composition can have a fragrance and can have a significant refreshing effect.

[0052] It should be understood that the guarana extract can be obtained by extracting guarana fruit or can be directly purchased. The guarana composition can be a lozenge, in which case the shape of the guarana composition is convenient for carrying and production. The guarana composition has different flavors if the flavoring agents used are different, so the guarana composition has a rich taste.

[0053] Further, the step of crushing the guarana extract to form guarana powder comprises:

[0054] Crush the guarana extract;

[0055] placing the crushed guarana extract on a first sieve for screening to obtain guarana powder;

[0056] Among them, the mesh number of the first sieve is 120 mesh to 200 mesh.

[0057] In this embodiment, after the guarana extract is crushed, the particle size of the guarana powder will affect the mixing uniformity of the guarana extract with the diluent, the flavoring agent and the fragrance, and further affect the mouthfeel of the prepared buccal tablet. Therefore, by using the first sieve for screening, the sieved guarana powder has a suitable particle size and can be fully mixed with the diluent, the flavoring agent and the fragrance.

[0058] It should be understood that the mesh number of the first sieve can be any one of 120 mesh, 125 mesh, 130 mesh, 135 mesh, 140 mesh, 145 mesh, 150 mesh, 155 mesh, 160 mesh, 165 mesh, 170 mesh, 175 mesh, 180 mesh, 185 mesh, 190 mesh, 195 mesh, and 200 mesh, or a range formed by any two of the values.

[0059] Further, the diluent includes one or more of maltodextrin, mannitol, lactose, inorganic salts, and starch; and / or,

[0060] The flavoring agent includes one or more of glucose, xylitol, sorbitol, sucralose, neotame, and powdered sugar; and / or,

[0061] The flavoring agent includes one or more of liquid flavor, microcapsule flavor, and cooling agent; and / or,

[0062] The proportions of guarana powder, diluent, flavoring agent, fragrance and wetting agent are (10-50):(10-20):(15-30):(5-15):(10-30).

[0063] In this embodiment, the proportions of guarana powder, diluent, flavoring agent, fragrance and wetting agent should be understood as follows: before preparing the first mixture, a total of 100 parts of the above-mentioned guarana powder, diluent, flavoring agent, fragrance and wetting agent should be prepared, of which guarana powder accounts for 10 to 50 parts, diluent accounts for 10 to 20 parts, flavoring agent accounts for 15 to 30 parts, fragrance accounts for 5 to 15 parts, and wetting agent accounts for 10 to 30 parts.

[0064] In this embodiment, the proportion of the guarana powder can ensure that the guarana extract has a good refreshing effect without overly stimulating the nerves; the range of the proportion of the flavoring agent can make the user feel a distinct but non-irritating fragrance when taking the guarana extract; the proportion of the flavoring agent can modify the taste of the guarana extract to make it conform to the common tastes of consumers, such as suppressing bitterness and irritation; the wetting agent can ensure that the second mixture can have a certain shape without being scattered into powder; the diluent can ensure that the preparation formula of the guarana extract can meet the requirement of 100 parts of each component, so that the production personnel can produce the guarana extract according to the formula.

[0065] It should be understood that the range of the number of parts of guarana powder includes any one of 10, 15, 20, 25, 30, 35, 40, 45, 50 or any two values. The range of the number of parts of diluent includes any one of 10, 12, 14, 16, 18, 20 or any two values. The range of the number of parts of the flavoring agent includes any one of 10, 15, 20, 25, 30 or any two values. The range of the number of parts of the flavoring agent includes any one of 5, 7, 9, 11, 13, 15 or any two values. The range of the number of parts of the humectant includes any one of 10, 15, 20, 25, 30 or any two values.

[0066] Furthermore, the wetting agent includes one or more of water, 75% ethanol, 8% starch slurry, sodium carboxymethyl cellulose, hydroxypropyl cellulose, methyl cellulose, and ethyl cellulose.

[0067] In this embodiment, the above-mentioned wetting agents can fully wet the guarana powder, the diluent, the flavoring agent and the fragrance agent, thereby bonding and integrating them to form the second mixture. The second mixture can be a soft material.

[0068] Further, the step of subjecting the second mixture to a shaping process to obtain a guarana composition comprises:

[0069] providing a lubricant, and mixing the lubricant with a second mixture to form a third mixture;

[0070] The third mixture was subjected to styling treatment.

[0071] Further, the second mixture is subjected to a molding process, which should be understood as processing the second mixture itself, or a derivative of the second mixture is subjected to a molding process. In the process of molding, it is usually necessary to perform extrusion hardening and demoulding on the material to be molded (e.g., the second mixture or the third mixture). The lubricant in this embodiment can prevent the material to be molded from being bonded to the tablet press, the mold and other structures during demoulding, thereby enabling the material to be molded to smoothly complete the extrusion printing and demoulding, and ensure that the final molded guarana composition has a complete form and a smooth surface.

[0072] Furthermore, the lubricant includes one or more of magnesium stearate, talc, micro-powdered silica gel, hydrogenated vegetable oil, and magnesium lauryl sulfate.

[0073] In this embodiment, the above lubricants can prevent the guarana extract from partially sticking to the mold and the tablet press.

[0074] Furthermore, in the guarana composition, the content of the lubricant is 0.2% to 1%; and / or,

[0075] The diameter of the guarana composition is 10 mm to 15 mm; and / or,

[0076] The thickness of the guarana composition is 3 mm to 5 mm; and / or,

[0077] The step of subjecting the third mixture to a shaping process to obtain a guarana composition comprises:

[0078] The third mixture is placed in a tabletting machine for tableting to obtain a guarana composition.

[0079] In this embodiment, the content range of the lubricant can ensure that the guarana extract is not partially adhered to the mold and the tablet press, thereby improving the integrity of the guarana composition. The length and thickness of the guarana composition can make the guarana composition have a small space occupancy rate, which is convenient for carrying and taking. The tablet press can quickly shape the third mixture into a guarana composition in the form of a buccal tablet.

[0080] Further, the step of drying the second mixture comprises:

[0081] placing the second mixture on a second sieve for screening;

[0082] drying the second mixture;

[0083] Wherein, the mesh number of the second sieve is 10-30 mesh; and / or,

[0084] The drying temperature is 50°C to 80°C; and / or,

[0085] Before the step of shaping the third mixture to obtain the guarana composition, the following step is also included: placing the third mixture on a second sieve for screening again.

[0086] In the present embodiment, the mesh number range of the second screen can make the size of the second mixture convenient for modeling, thereby producing a guarana composition of a size that is convenient for carrying and taking. The drying temperature can effectively remove the moisture in the second mixture, making it more conducive to modeling. Screening the third mixture again through the second screen can further avoid that after the lubricant is added, the size of the third mixture is changed compared with the second mixture, thereby avoiding that the actual size of the guarana composition is inconsistent with the preset. It should be understood that the mesh number of the second screen includes any value or any two values ​​in 10 mesh, 12 mesh, 14 mesh, 16 mesh, 18 mesh, 20 mesh, 22 mesh, 24 mesh, 26 mesh, 28 mesh, and 30 mesh.

[0087] Accordingly, the present application also provides a guarana composition, the materials of which include guarana extract, a diluent, a flavoring agent, a fragrance and a wetting agent.

[0088] In this embodiment, the guarana composition has guarana extract and flavoring agent, so it can refresh the mind and has a certain fragrance. At the same time, because it is solid, it is easy to carry and can be quickly taken orally.

[0089] Furthermore, the guarana composition is prepared by the preparation method of the guarana composition in any one of the above embodiments.

[0090] In this embodiment, the flavoring agent can make the guarana composition have a preset fragrance, and the flavoring agent can adjust the final taste of the guarana composition, thereby modifying the taste of the guarana composition. The lubricant can make the first mixture (dispersed) form the second mixture (soft material), so that the second mixture can be shaped after drying to form a guarana composition in a solid form. Guarana extract contains vitamins and caffeine with a maximum content of 22%, so it can slowly and long-term stimulate human nerves and play a refreshing effect, and the stimulation is relatively mild and harmless to the human body.

[0091] To facilitate understanding of the propolis supercritical extract and betel nut chewing gum in the above examples of the present application, the betel nut chewing gum in the examples of the present application will be specifically described below through experimental comparison.

[0119] Sensory evaluation data analysis

[0120] 10 professionally trained tasters were selected, with a male-female ratio of 1:1 and an average age of 25 to 35 years old. The tasters performed sensory evaluation on the embodiments and comparative examples according to the items in Table 1, and the average value was taken.

[0121] The subjects were forbidden to eat caffeine-containing products such as coffee and tea with refreshing effects within one day before the experiment. They were forbidden to drink water or eat food within one hour before the experiment. The experiment started at 1 pm and no lunch break was taken before the experiment. The evaluation process was as follows: the samples prepared in Examples 1 to 9 and Comparative Examples 1 to 2 were selected, and each person took one finished product. There was no chewing action during the experiment. The fragrance, oral comfort, and foreign body sensation of different samples were felt and scored. The stopwatch was used to time the release time of the guarana extract and the duration of the mental state. Each sample was tasted for at least 10 minutes, then spit out, rinsed several times until there was no residual taste in the mouth, and the next group of samples was measured in the same way after 10 minutes.

[0124]

[0125] Table 2

[0126]

[0127] The analysis results according to Table 1 and Table 2 are as follows:

[0128] According to Example 1 and Comparative Examples 1 and 2, compared with common coffee, the guarana composition prepared by the preparation method of the guarana composition of the present application has a more ornamental appearance, a stronger aroma, and good oral comfort when taken. Compared with the microcrystalline cellulose in Comparative Example 1, the refreshing effect of the guarana extract is obviously better.

[0129] According to Examples 1 to 4, changing the flavoring agent in the preparation of the guarana composition can greatly affect the flavor of the guarana composition, so the flavor type of the guarana composition can be changed by changing the ingredients of the flavoring agent, and the concentration of the flavor of the guarana composition can be changed by adjusting the content of the flavoring agent; at the same time, the flavoring agent can affect the taste of the guarana composition to a certain extent. The more guarana composition, the more obvious the refreshing effect.

[0130] In summary, according to the above sensory evaluation data analysis, the guarana composition in the examples of the present application has guarana extract and flavoring agent, so it can refresh the mind and have a certain fragrance.
