Description

Technical Field

[0001] The invention belongs to the technical field of tobacco flavoring, and particularly relates to a device and method for testing the performance of a flavoring substance. Background Art

[0002] Tobacco flavoring substances refer to various spices and flavorings added to tobacco products to improve the sensory properties of tobacco, expand airways, mask or mitigate the inherent odor and irritation of tobacco combustion, and enhance its aroma. These flavoring substances are an important component of tobacco additives, alongside humectants, combustion aids, mildew inhibitors, and adsorbents. In the production of Chinese cigarettes, the aroma and flavor are largely determined by the type and quality of the tobacco leaves, and the leaf blend determines the distinctive flavor characteristics of Chinese cigarettes. By adding ingredients and flavoring, deficiencies in the leaf blend can be compensated for or a unique aroma and flavor can be imparted to Chinese cigarettes, giving them their unique aroma and flavor characteristics.

[0003] In the existing production process of Chinese cigarettes, the adding process and the flavoring process increase the smoking taste and surface aroma of cigarettes respectively; among them, the adding process refers to the process of improving the smoking taste by spraying a liquid on tobacco leaves, stems or thin sheets. The liquid is a mixture of two or more tobacco flavorings, flavors and flavorings and a humectant (such as propylene glycol). This process aims to improve the smoking taste of tobacco, remove impurities, and increase the aroma and concentration of cigarettes. In addition, the flavoring process refers to the process of spraying a fragrant solution made by mixing two or more aromatic substances in proportion with propylene glycol or alcohol after the tobacco is dried and cooled. This process further enhances the surface aroma of cigarettes, making them have more attractive sensory characteristics. In the process of selecting and proportioning the adding and flavoring substances, it is necessary to take into account the aroma, smoke and taste, and finally to prepare tobacco with rich layers and a special aroma style. However, the current methods for testing the performance of tobacco adding and flavoring substances have the following shortcomings:

[0004] 1. Reliance on manual operation: Sensory evaluators manually add flavoring materials on site, spraying and mixing the raw materials. The evaluators then smoke the cigarettes and adjust the selection and proportion of flavoring materials based on their feelings.

[0005] 2. Complex operation and low efficiency: It is necessary to repeat the manual operation steps many times and cycle back and forth to find the optimal ratio of adding materials and flavoring substances, which is time-consuming and inefficient;

[0006] 3. Highly subjective: The smoking assessment process relies on the personal experience and feelings of the assessor and is greatly influenced by their physical condition, making it highly subjective.

[0007] 4. Lack of quantitative parameters: Since sensory evaluation relies on sensory feedback, it is difficult to record specific parameters using language or data. The sensory quality indicators based on existing cigarette sensory evaluation methods have limitations, which is not conducive to the accurate evaluation of the performance of adding materials and flavoring and technological innovation.

[0008] In view of this, the present invention is proposed. Summary of the Invention

[0009] In order to solve the above-mentioned technical problems existing in the prior art, the present invention provides a device and method for testing the performance of flavoring substances. The device can monitor respiratory parameters in real time and evaluate the performance of flavoring substances under a controlled environment, thereby overcoming the problem that the existing detection methods rely on the subjective experience of sensory evaluators.

[0010] To achieve the above object, the technical solution of the present invention is as follows:

[0011] In a first aspect, the present invention provides a device for testing the performance of a flavoring substance, comprising:

[0012] Intelligent physiological monitoring module: used to provide a sealed cavity to contain the smoke generated by the smoke generator and the aroma aerosol generated by the atomizer head, and to monitor and record the respiratory parameters of the animals in the cavity in real time;

[0033] Obtain the enhanced expiratory interval value A of the experimental mice during simple smoke inhalation;

[0034] During the simultaneous inhalation of smoke and aroma, the standard is that the enhanced exhalation interval value recovers by 30%; when the enhanced exhalation interval of mice recovers to A×70% during the co-inhalation of a certain flavoring substance and smoke, it is judged that this flavoring substance is effective in alleviating the burning irritation and dryness of cigarettes.

[0035] Furthermore, the inhalation peak flow rate is used to evaluate the performance of the flavoring substance in improving smoke satisfaction and aroma inhalation volume, and the specific method is as follows:

BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The technical solution of the present invention will be clearly described below in conjunction with the accompanying drawings. Obviously, the described embodiments are not all embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0042] It should be noted that, unless otherwise specifically stated, the relative arrangements of components and steps, and numerical expressions set forth in these embodiments should not be construed as limiting the scope of the present invention.

[0043] The following description of exemplary embodiments is merely illustrative and is not intended to limit the present invention, its application, or use in any sense. Technologies, methods, and apparatus known to those skilled in the art may not be discussed in detail herein, but to the extent applicable, such technologies, methods, and apparatuses should be considered part of this specification.

[0044] Example 1

[0045] See Figure 1 , Figure 1This is a schematic diagram of a device for testing the performance of a flavoring substance according to an embodiment of the present invention. The device can monitor respiratory parameters in real time and evaluate the performance of the flavoring substance under a controlled environment, overcoming the problem that existing detection methods rely on the subjective experience of sensory evaluators. Figure 1 As shown, the tobacco flavoring material performance testing device may specifically include:

[0046] A1. Intelligent physiological monitoring module

[0047] The intelligent physiological monitoring module is used to provide a closed cavity to contain the smoke generated by the smoke generator and the aerosol generated by the atomizer head, and to monitor and record the respiratory parameters in the cavity in real time. The module indirectly reflects the respiratory parameters by measuring the volume changes of the animal in the closed cavity. Specific functions include:

[0048] A11. Provide a closed cavity to accommodate experimental animals. The size and design of the cavity must meet the physiological requirements of the experimental animals to ensure that the animals can breathe freely during the experiment. The sealing of the cavity is automatically detected and adjusted by the intelligent physiological monitoring module to ensure the stability of the experimental conditions.

[0049] A12. Real-time monitoring of the respiratory status of experimental animals: Sensors are installed in the cavity of the intelligent physiological monitoring module to monitor the respiratory parameters of experimental animals. Respiratory parameters include respiratory rate, enhanced expiratory interval, peak inspiratory flow, and end-respiratory braking time. The respiratory parameter data are transmitted to the evaluation module for subsequent evaluation.

[0050] Among them, the respiratory frequency is used to evaluate the irritation of the smoke and the performance of the flavoring substance; the end-respiratory braking time is used to evaluate the performance of the flavoring substance in terms of the irritation of the smoke; the enhanced expiratory interval is used to evaluate the performance of the flavoring substance in reducing the burning irritation and dryness sensation; the peak inspiratory flow is used to evaluate the performance of the flavoring substance in improving the smoke satisfaction and the amount of aroma inhaled.

[0051] A2. Smoke generator:

[0052] The smoke generator module generates smoke and discharges it into the cavity of the intelligent physiological monitoring module. The smoke generator precisely controls smoke production by adjusting parameters such as puff frequency, puff volume, and puff duration. To ensure smoke uniformity and stability, the smoke generator is connected to a smoke collection pipe, which directs the smoke into the cavity to prevent leakage. An EVT smoke generator can be used, which features adjustable puff parameters to ensure stable smoke concentration during experiments.

[0053] A21, airbag assembly: used to control the suction frequency, suction volume and suction duration;

[0054] A22, smoke collection pipe: used to ensure that the generated smoke is isolated from the fuselage itself. The smoke collection pipe of the smoke generator is inserted into the cavity of the intelligent physiological monitoring module and sealed with a sealing component to ensure the airtightness of the cavity.

[0055] A3, atomizer head module

[0056] The atomizer head module is used to add a solution of flavoring substances in a set ratio to form an aerosol, which is then discharged into the cavity of the intelligent physiological monitoring module together with the smoke. The atomizer head converts the flavoring substance solution into an aerosol, mixes it with the smoke, and then delivers it into the cavity of the intelligent physiological monitoring module where the experimental animal is located.

[0057] The atomizer head uses a precise spray mechanism to mix a flavoring solution with tobacco smoke in a pre-set ratio, forming an aerosol for inhalation by the experimental animals. The flavoring solution's composition is tailored to the experimental needs, typically including a variety of flavors, fragrances, and humectants, ensuring a comprehensive assessment of the flavoring's effects on tobacco.

[0058] The adjustment function of the atomizer head module can be used in conjunction with the intelligent physiological monitoring module to adjust the mixing ratio of aroma substances and smoke based on real-time monitored respiratory parameters, such as peak inspiratory flow and enhanced expiratory interval, to achieve the best sensory effect and experimental requirements.

[0059] A4. Evaluation Module

[0060] The evaluation module is used to evaluate the performance of flavoring substances based on changes in respiratory parameters detected by the intelligent physiological monitoring module. The evaluation module analyzes the monitored respiratory parameters and evaluates the performance of flavoring substances based on the physiological responses of experimental animals. Specifically, the evaluation module comprehensively evaluates the performance of flavoring substances based on the following key respiratory parameters. The evaluation indicators include the impact on both negative evaluations of tobacco (such as burning irritation and dryness) and positive evaluations (such as aroma inhalation and smoke satisfaction).

[0061] A41. Enhanced expiratory pause

[0062] The EEP reflects the degree of airway narrowing. Normally, the EEP value is low, typically 0.45. However, when inhaling smoke, this value increases, indicating airway irritation and a burning or dry sensation. If the EEP value increases significantly during smoking (for example, from 0.45 to 2.47), the smoke is highly irritating, and a burning or dry sensation is considered a negative assessment.

[0063] When the aroma is inhaled with tobacco smoke, the value of the enhanced exhalation interval may recover, indicating that the aroma is effective in alleviating the burning and dryness of tobacco. When the enhanced exhalation interval returns to close to 0.45 (for example, 1.73), it can be considered that the aroma is performing well in improving these negative sensations.

[0064] A42, peak inspiratory flow

[0065] The peak inspiratory flow rate reflects the patency of the airway. Under normal circumstances, the peak inspiratory flow rate is 5.66mL / s, indicating normal airway conductivity. When inhaling smoke, this value usually decreases, reflecting that the airway is irritated. When inhaling smoke, if the peak inspiratory flow rate drops significantly (for example, from 5.66mL / s to 3.2mL / s), it means that the airway is stimulated by the smoke and the airway patency has deteriorated. This situation corresponds to the sensory evaluators' assessment of the "irritation" or "burning sensation" of cigarettes.

[0066] When aroma substances are inhaled together with smoke, the peak inspiratory flow rate may rebound (for example, from 3.2 mL / s to 4.16 mL / s). If the value returns to a value close to the normal value of 5.66 mL / s, it indicates that the aroma substances help improve airway conductivity, thereby improving the amount of aroma inhaled and the satisfaction of smoke. When the enhanced expiratory interval recovery reaches more than 30%, the aroma substances are judged to be effective in reducing the burning irritation. When the peak inspiratory flow rate is increased by more than 30% compared with the exposure to smoke alone, the aroma substances are judged to be effective in improving the amount of aroma inhaled, providing a positive assessment.

[0067] The evaluation module comprehensively assesses the effects of additives and flavorings, providing detailed analysis from both a negative and positive perspective. This reduces subjectivity, provides quantitative and standardized evaluation criteria, and allows for rapid selection of the most suitable flavoring combinations.

[0068] Example 2

[0069] This embodiment provides a method for testing the performance of a flavoring substance, which is used in conjunction with the above-mentioned device for testing the performance of a flavoring substance. The method for testing the performance of a flavoring substance includes:

[0070] S1. placing an experimental mouse in the cavity of the intelligent physiological monitoring module;

[0071] S2. After the set time period is reached, the smoke generator is connected to the intelligent physiological monitoring module;

[0072] S3, placing the smoke to be tested in a smoke generator, starting the smoke generator, and igniting the smoke to be tested to generate smoke, which is then sent into the cavity of the intelligent physiological monitoring module;

[0073] S4. While performing step S3, the atomizing head module is started to atomize the fragrance substance to generate a fragrance aerosol, and the fragrance aerosol is sent into the cavity of the intelligent physiological monitoring module;

[0074] S5. The intelligent physiological monitoring module collects respiratory parameters of the experimental mice;

[0075] S6. Evaluate the performance of tobacco flavoring substances based on respiratory parameters.

[0076] The respiratory parameters include respiratory rate, enhanced expiratory pause, peak inspiratory flow, and end-of-expiratory brake time. The enhanced expiratory pause is used to evaluate the performance of the flavoring substance in reducing burning irritation and dryness, while the peak inspiratory flow is used to evaluate the performance of the flavoring substance in improving smoke satisfaction and aroma inhalation volume.

[0077] The enhanced expiratory interval evaluates the effect of flavoring substances in relieving burning and dryness by analyzing the changes in the breathing patterns of experimental mice when they inhale pure smoke and a mixture of smoke and aroma. The specific method is: first, the enhanced expiratory interval value A of the experimental mice during the inhalation of pure smoke is obtained; then, when smoke and aroma are inhaled at the same time, the standard of 30% recovery of the enhanced expiratory interval is set as a reference. If the enhanced expiratory interval of the experimental mice recovers to 70% of A (i.e. A×70%) after a certain flavoring substance is inhaled together with smoke, it is determined that the flavoring substance is effective in reducing the burning irritation and dryness of smoke. This method provides a quantitative basis for the effect of flavoring substances by quantifying the changes in breathing patterns, and has high reliability and reproducibility.

[0078] The inhalation peak flow rate is used to evaluate the performance of the flavoring substance in improving the satisfaction of smoke and the amount of aroma inhaled, and can directly reflect the satisfaction and amount of aroma when inhaling smoke. The specific method is: first, obtain the inhalation peak flow rate value B of the experimental mouse during the inhalation of simple smoke. Then, during the simultaneous inhalation of smoke and aroma, set the standard of increasing the inhalation peak flow rate by 30% as the evaluation benchmark. If the inhalation peak flow rate of the mouse increases to B×130% when a certain flavoring substance is inhaled together with smoke, it is determined that the flavoring substance is effective in improving the satisfaction of smoke and the amount of aroma inhaled. This method not only quantifies the impact of flavoring substances on the feeling of smoke inhalation, but also can help screen out flavoring substances that can effectively enhance the inhalation experience in practical applications.

[0079] Example 3

[0080] This example uses a fragrance performance testing device and fragrance performance testing method provided by the present invention to monitor real-time changes in lung physiological responses in mice. The intelligent physiological monitoring module utilizes a whole-body plethysmograph (WBPG), which also includes an atomizer head and an evaluation module. In this example, the untethered WBPG module utilizes a DSI FinePointe series WBP device.

[0081] The smoke generator is an EVT smoke generator, using DSI's Buxco series EVT equipment. The following describes the process of using this device to evaluate the flavoring properties of three flavoring substances (citric acid, furanone, and ethyl maltol) as examples.

[0082] B1. Preparation before the experiment

[0083] Before the experiment began, participating mice were individually placed in the unrestrained whole-body plethysmography chamber for at least three days of acclimatization. This process ensured that the mice were acclimated to the chamber environment and reduced the impact of stress on experimental results. During this time, the intelligent physiological monitoring module recorded the mice's respiratory parameters, including respiratory rate, peak inspiratory flow, and expiratory interval, in real time.

[0084] Insert the smoke generator's smoke collection tube into the WBP cavity through the pre-set hole. Use a rubber ring to seal the gap between the smoke collection tube and the pre-set hole to prevent smoke from escaping the cavity and ensure the entire cavity is airtight. The smoke collection tube is connected to the EVT smoke generator, which is responsible for generating smoke and directing it into the WBP cavity.

[0085] The puff parameters of the EVT aerosol generator include puff frequency, puff volume, and puff duration. Before the experiment begins, the puff parameters are set to align with the sensory evaluators' puff frequency, volume, and duration to ensure that the release of aerosol and flavoring substances meets the expected standards.

[0086] B2. Experiment begins

[0087] At the start of the experiment, the EVT and WBP modules were activated. The atomizer head module uniformly adjusted the atomization rate of the aroma compound, ensuring precise concentration, distribution, and inhalation effect. After acclimating to the chamber, the mouse was placed in the WBP chamber, and the module began recording its respiratory parameters in real time.

[0088] A plain cigarette was placed above the airbag, the smoke generator activated, the cigarette tip ignited, and the mouse began to inhale. As the airbag deflated, smoke aerosols passed through the smoke collection tube into the WBP cavity, where the mouse inhaled both the smoke and the flavoring aerosols. Simultaneously, the atomizer head activated, ensuring that the flavoring aerosols were evenly distributed throughout the cavity and inhaled by the mouse.

[0089] B3. Addition and atomization of flavoring substances

[0090] While the smoke generator is running, the atomizer converts the flavoring solution into an aerosol and releases it along with the smoke. The atomizer sprays the flavoring in a preset ratio, ensuring a uniform mixture of the flavoring and smoke, forming an aerosol for the experimental animals to inhale.

[0091] B4. Data Collection and Evaluation:

[0092] During the experiment, the WBP module recorded and analyzed the mice's respiratory parameters in real time to observe the performance of the fragrance. The following is the effect of different fragrances on the mice's respiratory parameters:

[0093] Citric acid: When inhaled together with tobacco smoke, the enhanced expiratory interval of mice recovered to 1.07, and the peak inspiratory flow rate decreased by 39% to 1.95 mL / s, indicating that citric acid effectively reduced the burning irritation and dryness of tobacco and achieved better flavoring performance.

[0094] Furanone: When inhaled together with smoke, the enhanced expiratory interval of mice remained almost unchanged (2.62), and the peak inspiratory flow rate increased slightly to 3.85 mL / s, indicating that furanone did not significantly reduce the burning irritation, but improved the smoke satisfaction by slightly increasing the amount of aroma inhaled.

[0095] Ethyl maltol: When inhaled together with tobacco smoke, the enhanced expiratory interval of mice recovered to 1.84, and the peak inspiratory flow rate increased to 5.95 mL / s, indicating that ethyl maltol is not as good as citric acid in reducing the burning irritation of tobacco, but it can significantly increase the amount of aroma inhaled and greatly increase the satisfaction of smoking.

[0096] B5. Results and Analysis:

[0097] Citric acid: It performs best in reducing the burning sensation and dryness of cigarettes.

[0098] Ethyl maltol: It has the most significant performance in increasing aroma inhalation and increasing smoke satisfaction.

[0099] Furanone: It hardly plays a role in reducing the burning sensation, but slightly improves the aroma inhalation and increases the satisfaction of the smoke.

[0100] Through this example, it can be found that citric acid, furanone, and ethyl maltol have different flavoring properties among flavoring substances. Citric acid mainly improves the negative evaluation of tobacco by reducing the burning irritation and dryness; ethyl maltol performs well in increasing the amount of aroma inhaled and increasing the satisfaction of smoke; furanone is relatively weak in flavoring performance, but can still moderately improve the smoke inhalation experience. Through multiple rounds of repeated experiments and data comparison and analysis, the solution mass-to-liquid ratio of each flavoring substance can be further optimized to find the most suitable flavoring ratio in each dimension or to highlight the performance of a specific dimension according to specific requirements.

[0101] In summary, the present invention has the following advantages:

[0102] 1. Experimental animals are used to replace sensory evaluators. By selecting mice with a respiratory module similar to that of humans, the performance of the fragrance substances is characterized by changes in their respiratory parameters, which reduces the subjectivity of the experiment.

[0103] 2. The introduction of precision instruments to achieve quantitative detection, the use of EVT and WBP modules in combination, to achieve real-time monitoring of the performance of cigarette smoke and flavoring substances, providing quantifiable evaluation indicators, replacing the traditional experience-based evaluation method.

[0104] 3. Conduct a step-by-step evaluation of additives and flavorings, separating their performance. Through different experimental designs, the flavor improvement and surface aroma enhancement performance of cigarettes are tested separately, thereby optimizing the flavoring scheme more scientifically.

[0105] 4. Establishment of standardized evaluation indicators. Through the multi-dimensional correlation between respiratory parameters and sensory inhalation feedback, comprehensive evaluation standards including burning irritation, dryness, aroma inhalation volume and smoke satisfaction are proposed to achieve standardized analysis of the performance of flavoring substances.

[0106] The above specific embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
