[0035] Matsutake mushrooms are a prized edible fungus, highly favored by consumers for their unique aroma, delicious flavor, and high nutritional value. Fresh matsutake mushrooms have a high water content, requiring quality testing and grading after harvesting before entering the distribution channels, such as being transported to consumers, supermarkets, or farmers' markets. Because matsutake mushrooms have very active respiration and metabolism after harvesting, they are extremely prone to softening and rotting. Therefore, minimizing the time spent on testing and grading is crucial for maintaining good quality. Consequently, the entire process demands extremely high efficiency.

[0036] In related technologies, quality testing of matsutake mushrooms through specialized biochemical laboratories requires specialized equipment and involves damaging and sampling the mushrooms to obtain relevant biochemical data. Alternatively, puncture-type texture analysis requires inserting a texture analyzer probe into the mushroom to measure parameters such as hardness, viscosity, elasticity, and cohesion to assess quality. This method demands high levels of expertise from both the equipment and the operators and can damage the mushrooms. Other testing methods, such as manual pressing and observation, rely on the sensory perception of the personnel to judge hardness, elasticity, size, surface characteristics, and integrity. This requires extensive experience from the personnel, is highly subjective, and its accuracy is difficult to guarantee. Therefore, current testing methods are insufficient to meet the need for non-destructive, rapid, and accurate quality assessment of matsutake mushrooms.

[0037] This application provides a detection device that can detect matsutake mushrooms by placing a probe against the surface of the mushroom, avoiding damage, reducing subjectivity, and enabling convenient, fast, and accurate quality assessment. The embodiments of this application are described below with reference to the accompanying drawings.

[0038] refer to Figure 1 and Figure 2 The detection device in this application embodiment is used for matsutake mushroom quality assessment. The detection device includes a detection system, an indicator system, and a presentation system.

[0039] The presentation system includes a housing 100 and a presentation area 200 located outside the housing 100. The presentation area 200 is used to visually present the test results in conjunction with the indicator system.

[0040] The detection system includes a probe 300 and an elastic element 400. The probe 300 is movably connected to the housing 100. The elastic element 400 is disposed between the housing 100 and the probe 300, such that one end of the probe 300 is exposed outside the housing 100 and in its initial position. When the exposed end of the probe 300 is pushed into the housing 100 by an external force, the elastic element 400 undergoes elastic deformation. After the external force is removed, the probe 300 moves outward from the housing 100 under the restoring force of the elastic element 400, thus returning to its initial position.

[0041] The indicating system includes a transmission component 600 and an indicator 700 connected to the transmission component 600. The transmission component 600 is driven by the probe 300, thereby moving the indicator 700. The indicator 700 is located outside the housing 100 and at least partially above the presentation area 200, which has multiple sub-areas 210 distributed sequentially along the direction of movement of the indicator 700. Thus, when the exposed end of the probe 300 is pushed inward into the housing 100 by an external force, thereby driving the transmission component 600, the transmission component 600, driven by the probe 300, can move the indicator 700 to the corresponding position in one of the sub-areas 210. For example, the indicator 700 may be at least partially located above the area of ​​the presentation area 200 where sub-regions 210 are provided. The indicator 700 moves relative to the presentation area 200 to reach above one of the sub-regions 210, which is the sub-region 210 corresponding to the current indicator 700. Alternatively, the presentation area 200 may have multiple sub-regions 210 located outside one end of the indicator 700. One end of the indicator 700 may point to one of the sub-regions 210. The indicator 700 moves relative to the presentation area 200 until one end points to one of the sub-regions 210, which is the sub-region 210 corresponding to the current indicator 700. Thus, the movement of the probe 300 into the housing 100 is converted into movement of the indicator 700, thereby allowing the indicator 700 to move to different sub-regions 210 corresponding to different positions within the presentation area 200 depending on the displacement of the probe 300.

[0042] Different grades of matsutake mushrooms have different surface textures, resulting in varying displacements when the probe 300 contacts the surface. The detection device in this embodiment uses the positional change of the indicator 700 relative to the presentation area 200 to reflect the displacement of the probe 300 when it contacts the matsutake surface. This characterizes the surface texture of the matsutake and correlates it with the measured quality grade, thus reflecting the quality grade of the matsutake. Furthermore, the detection device in this embodiment correlates the movement range (e.g., travel range or rotation angle range) of the indicator 700 with the measured quality grade, marking sub-regions 210 representing each quality grade within the presentation area 200. Thus, the sub-regions 210 corresponding to the indicator 700 visually represent the quality grade of the currently tested matsutake, facilitating rapid identification by testing personnel and achieving non-puncture detection of matsutake quality grades, meeting the requirements of non-destructive, convenient, and accurate testing.

[0043] In specific implementation, the quality grade of matsutake mushrooms is marked in each sub-region 210 of the presentation area 200. For example, the grade can be divided by the measured quality results of commonly used quality testing methods (such as the aforementioned biochemical testing and puncture texture testing). The results of testing matsutake mushrooms of each quality grade by the testing device of this application embodiment are correspondingly marked with the measured quality grade, and sub-regions 210 representing each grade are divided in the presentation area 200 accordingly. Alternatively, the testing device of this application embodiment can be used to test matsutake mushroom samples under different storage conditions (temperature, humidity, duration, etc.), and the quality grade of the corresponding matsutake mushroom sample can be obtained by testing the same matsutake mushroom sample using commonly used quality testing methods (such as the aforementioned biochemical testing and puncture texture testing), and the results can be corresponding to the test results of the testing device, and sub-regions 210 representing each grade are divided in the presentation area 200 accordingly. Therefore, the quality grade classification criteria of each sub-region 210 of the presentation area 200 in this embodiment of the application are obtained after being calibrated by biochemical test results and / or puncture texture test results, thus avoiding the subjectivity and inaccuracy of manual methods.

[0044] In use, the detection device of this embodiment allows the probe 300 to be placed against the surface of the matsutake mushroom. Under the action of the matsutake's epidermis, the probe 300 is forced to move inward toward the outer shell 100, and the transmission component 600 drives the indicator 700 to move to a sub-region 210 corresponding to the presentation area 200. Thus, the quality grade of the matsutake can be visually presented through the sub-region 210 corresponding to the indicator 700, eliminating the need to cut or pierce the matsutake sample for testing and avoiding the subjectivity of manual pressing and observation. This achieves rapid and non-destructive testing of matsutake quality. After testing, the probe 300 is removed from the matsutake surface, and under the action of the elastic component 400, the probe 300 returns to its initial position. The transmission component 600 then drives the indicator 700 to reset, allowing for the next test.

[0045] The detection device of this application embodiment indicates the quality of matsutake mushrooms on the display area 200 through a mechanical structure. It is convenient and quick to operate, providing an important reference for rapidly determining the freshness of matsutake mushrooms and facilitating quality assessment and grading of matsutake mushrooms before distribution or market entry. It is understood that matsutake mushrooms continue to metabolize during transportation or shelf life. The detection device of this application embodiment can also meet the quality detection needs of matsutake mushrooms at various stages such as refrigeration, transportation, or shelf life, avoiding destructive testing and the subjectivity of manual assessment.

[0046] It is understandable that fresher matsutake mushrooms have a higher water content and a relatively harder outer skin, resulting in less elastic deformation under stress. As respiration and metabolism continue, the mushrooms lose moisture, causing them to soften easily, reducing the hardness of the outer skin and increasing elastic deformation under stress. Therefore, for fresher matsutake mushrooms, when the probe 300 presses against the surface, the outer skin sinks less, resulting in a relatively larger displacement of the probe 300 towards the outer shell 100. This leads to a larger movement amplitude of the indicator 700, indicating a harder outer skin. Conversely, for less fresh matsutake mushrooms, the outer skin hardens less, sinking more. Consequently, the probe 300 moves less towards the outer shell 100, resulting in a smaller movement amplitude of the indicator 700, indicating a softer outer skin. Therefore, the texture of the matsutake mushroom can be judged by the magnitude of the movement of the indicator 700 relative to the presentation area 200. The magnitude of the movement of the indicator 700 relative to the presentation area 200 can be intuitively represented by the sub-area 210 corresponding to the indicator 700. Based on this, the quality of the matsutake mushroom can be evaluated intuitively and objectively.

[0047] refer to Figure 1 and Figure 2 Furthermore, each sub-region 210 can have different level labels 220, and each level label 220 can have at least one of different text, color, or graphic, thereby further facilitating the reading of detection results. For example:

[0048] In one example, the grade labels 220 in each sub-region 210 are different text labels. Along the movement direction of the indicator 700, the text of the grade labels 220 in each sub-region 210 represents the quality grade of the matsutake mushroom, increasing sequentially from low to high. The sequentially set text labels can be "Grade 1", "Grade 2", "Grade 3", "Grade 4", etc., or "Grade 1", "Grade 2", "Grade 3", "Grade 4", etc. When "Grade 1" or "Grade 1" represents a lower quality grade, and a larger number represents a higher quality grade of matsutake mushroom, they are arranged sequentially along the movement direction of the indicator 700; otherwise, they are arranged in reverse order. Alternatively, they can be text such as "Low", "Low-Medium", "Medium", "Medium-High", "High", etc. During testing, the quality grade of the current matsutake mushroom can be obtained according to the grade label 220 corresponding to the indicator 700.

[0049] Alternatively, in another example, the grade markers 220 in each sub-region 210 are different color markers. Different grades can be represented by different colored blocks in each sub-region 210. For example, different colored stickers or coatings can be applied to each sub-region 210. Alternatively, if the presentation area 200 is a single sticker, different colors can be printed onto each sub-region 210 of the presentation area 200. In this example, different color families can be used to represent "different colors," thus representing different grades. Alternatively, different shades of the same color family can be used to represent "different colors." In this case, the shade of the color can indicate the quality grade; for example, a darker color indicates a higher quality grade, or vice versa.

[0050] Alternatively, in another example, the grade identifiers 220 in each sub-region 210 can also be different shape identifiers. In this example, "different shape identifiers" can also be shape identifiers with different graphics, or "different shape identifiers" can refer to shape identifiers with the same graphics but different sizes. In this case, the quality grade can be represented by the size of the shape identifier. For example, the larger the shape, the higher the quality grade, or vice versa.

[0051] The above-mentioned level identifiers 220 can be combined with each other without conflict. For example, the level identifiers 220 in each sub-region 210 can be different text identifiers or shape identifiers. At the same time, these identifiers can be configured to have different colors, or different color identifiers can be set in each sub-region 210, while also setting different text identifiers or shape identifiers. Specific combination methods are not listed one by one here. The level identifiers 220 in each sub-region 210 only need to be able to be visually distinguished.

[0052] refer to Figure 3 and Figure 4 In some embodiments, the presentation system may further include a display dial 230, which is located between and connected to the housing 100 and the indicator 700. A presentation area 200 is located on the side of the display dial 230 facing the indicator 700. The presentation area 200 may be a layered structure connected to the side of the display dial 230 facing the indicator 700. For example, the presentation area 200 may be a patch, attached to the display dial 230 by adhesive or other means. Alternatively, the presentation area 200 may be a coating, attached to the display dial 230 by coating or other means, facilitating the separate manufacturing of the display dial 230 and the presentation area 200. Alternatively, the presentation area 200 may also be a structure formed on the display dial 230. For example, the presentation area 200 may be formed partially or entirely on the side of the display dial 230 facing the indicator 700, eliminating the need for assembly steps between the presentation area 200 and the display dial 230.

[0053] Alternatively, in some embodiments, the display system may not require a separate display dial 230. Instead, a display area 200 may be provided on the outer surface of the housing 100. The display area 200 may be a layered structure attached to the outer surface of the housing 100. For example, the display area 200 may be a patch attached to the outer surface of the housing 100 facing the indicator 700 by means of adhesive bonding or other methods. Alternatively, the display area 200 may be a coating attached to the outer surface of the housing 100 facing the indicator 700 by means of coating or other methods. This facilitates the separate manufacturing of the display housing 100 and the display area 200. Alternatively, the display area 200 may also be a structure formed on the outer surface of the housing 100. For example, the display area 200 may be formed on a partial or entire area of ​​the outer surface of the housing 100 facing the indicator 700, which eliminates the assembly process for the display area 200.

[0054] refer to Figure 3 and Figure 4 As an example, the indicator 700 may be a long, narrow pointer structure. One end of the indicator 700 is connected to the gear structure, and the other end is located above the position where the presentation area 200 has a sub-region 210, or the other end points to the position where the presentation area 200 has a sub-region 210. Thus, the indicator 700 rotates relative to the presentation area 200 as driven by the gear structure, so that the other end of the indicator 700 rotates to be above or points to one of the sub-regions 210.

[0055] In some embodiments, when the probe 300 is in the initial position, the indicator 700 corresponds to one side edge of one of the sub-regions 210. At this time, the position of the indicator 700 can be counted as the zero position of the indicator 700. The remaining sub-regions 210 are distributed in a circle or arc along the rotation direction of the indicator 700. Therefore, during detection, the probe 300 moves a certain distance from the initial position so that the indicator 700 rotates from the zero position to correspond to one of the sub-regions 210. When the detection ends, the probe 300 returns to the initial position, thereby driving the indicator 700 back to the zero position through the transmission member 600.

[0056] In some embodiments, the transmission member 600 includes a gear structure rotatably connected to the housing 100. The gear structure has a gear ring, and the outer periphery of the probe 300 has a rack structure 330 that meshes with the gear ring. The gear structure is connected to the indicator 700 to drive the indicator 700 to rotate. Therefore, when the probe 300 moves, the rack structure 330 can drive the gear structure to rotate, thereby driving the indicator 700 to rotate. The rotation angle of the indicator 700 indicates the amount of movement of the probe 300. Correspondingly, each sub-region 210 of the presentation area 200 is distributed circumferentially or in an arc along the rotation direction of the indicator 700, forming a disc-shaped or fan-shaped dial. Thus, when the indicator 700 rotates to correspond to one of the sub-regions 210, the detection result can be indicated. The structure is simple and easy to read.

[0057] refer to Figure 2 In some embodiments, the gear structure may include a meshing first gear 610 and a second gear 620, which are rotatably connected to the housing 100. The probe 300 is meshed with the first gear 610 via a rack structure 330, and the indicator 700 is connected to the wheel surface or axle of the second gear 620. Therefore, when the probe 300 moves, the rack structure 330 drives the first gear 610 to rotate, which in turn drives the meshing second gear 620 to rotate. Consequently, the indicator 700 rotates with the second gear 620, and the rotation angle of the indicator 700 indicates the amount of movement of the probe 300. The engagement of the first gear 610 and the second gear 620 enables transmission while allowing for easy configuration of the transmission ratio as needed. The travel of the probe 300 is amplified proportionally by the transmission component 600 and reflected in the rotation angle of the indicator 700, making the test results easier to identify.

[0058] As an example, in the gear structure, the first gear 610 includes a first gear ring 611 and a second gear ring 612, which are arranged axially along the first gear 610 and are coaxially arranged. The second gear 620 includes a third gear ring 621. The rack structure 330 on the probe 300 meshes with the first gear ring 611, and the third gear ring 621 meshes with the second gear ring 612. The second gear ring 612 is larger than the first gear ring 611. Thus, when the probe 300 drives the first gear 610 to rotate through the first gear ring 611, the first gear 610 can amplify and transmit the stroke of the rack structure 330 to the second gear 620 through the second gear ring 612, thereby driving the indicator 700 to rotate with the amplified rotation amplitude. In this design, the third gear ring 621 on the second gear 620 can be the same as the second gear ring 612 of the first gear 610. This allows the second gear 620 to rotate in a proportional manner based on the motion amplified by the second gear ring 612. Alternatively, in some examples, the third gear ring 621 can be smaller than the second gear ring 612. Compared to the same design, this can further amplify the stroke, allowing the second gear 620 to rotate to a greater extent, which is more helpful in demonstrating the subtle differences in the travel of the probe 300.

[0059] In some embodiments of the detection device, the indicator 700 can also be moved by the transmission member 600. For example, the indicator 700 can also be engaged with the gear ring of the gear structure via the rack structure 330, so that when the probe 300 moves, the gear structure can be rotated by the rack structure 330 on the probe 300. The gear structure drives the indicator 700 to move via the rack structure 330 of the indicator 700. The amount of movement of the indicator 700 represents the amount of movement of the probe 300. At this time, the presentation area 200 is distributed with multiple sub-areas 210 along the movement direction of the indicator 700, so that the test result is characterized by the indicator 700 moving to a position corresponding to a sub-area 210 of the presentation area 200. Similarly, the displacement of the probe 300 can be amplified and converted into the displacement of the indicator 700 by the gear set of the transmission member 600, for example:

[0060] refer to Figure 2In some embodiments, the gear structure may include a meshing first gear 610 and a second gear 620, which are rotatably connected to the housing 100. The probe 300 has a first rack structure 330 on one side wall inside the housing 100. A portion of the indicator 700 is located inside the housing 100 and has a second rack structure. The probe 300 meshes with the first gear 610 via the first rack structure 330, and the indicator 700 meshes with the second gear 620 via the second rack structure. Therefore, when the probe 300 moves, the first gear 610 can be rotated via the first rack structure 330, and the first gear 610 can rotate the meshing second gear 620. Thus, the second gear 620, through the second rack structure, causes the indicator 700 to move with the rotation of the second gear 620. The displacement of the indicator 700 relative to the presentation area 200 indicates the amount of movement of the probe 300. The first gear 610 and the second gear 620 work together to achieve transmission, and the transmission ratio can be easily configured as needed. The stroke of the probe 300 is amplified by a certain proportion through the transmission component 600 and reflected in the rotation angle of the indicator 700, making the test results easier to identify.

[0061] refer to Figure 2 As an example, in the gear structure, the first gear 610 includes a first gear ring 611 and a second gear ring 612, which are arranged along the axial direction of the first gear 610 and are coaxial. The second gear 620 includes a third gear ring 621. The first rack structure 330 on the probe 300 meshes with the first gear ring 611, and the third gear ring 621 meshes with the second gear ring 612. The second gear ring 612 is larger than the first gear ring 611. Thus, when the probe 300 drives the first gear 610 to rotate through the first gear ring 611, the first gear 610 can amplify the stroke of the first rack structure 330 and transmit it to the second gear 620 through the second gear ring 612. As a result, the second gear 620 drives the indicator 700 to move with the amplified movement amount through the second rack structure it meshes with, realizing a proportional linear amplification of the stroke. In this design, the third gear ring 621 on the second gear 620 can be the same as the second gear ring 612 on the first gear 610. Thus, the stroke amplified by the second gear ring 612 drives the second gear 620 to rotate in the same proportion, thereby moving the indicator 700. Alternatively, in some examples, the third gear ring 621 can be smaller than the second gear ring 612. Compared to the same solution, this can further amplify the stroke, allowing the second gear 620 to rotate more significantly, thereby driving the indicator 700 to move a greater distance. This is more helpful in demonstrating the subtle differences in the travel of the probe 300.

[0062] In use, the detection device of this embodiment can be stably placed above the surface of the matsutake mushroom, with the probe 300 aligned with the area to be detected on the matsutake's surface. Appropriate manual pressure is applied until the matsutake's surface contacts the outer shell 100. At this point, the probe 300 moves upward under the resistance of the matsutake's surface. Different grades of matsutake have different textures and produce different elastic deformations under pressure, resulting in different movement distances of the probe 300. In some embodiments, when the probe 300 is in its initial position, the length L extending from the outer edge of the outer shell 100 relative to the probe 300 can be 4mm to 6mm, specifically 4mm, 4.5mm, 5mm, 5.5mm, 6mm, or any other value between 4mm and 6mm, thus realizing a short-range detection device suitable for matsutake surface detection. The extension length L of the probe 300 is kept within the above range to be suitable for detecting matsutake mushrooms of various freshness. This avoids the problem that the extension length L of the probe 300 is too short, making it difficult to detect matsutake mushrooms with softer skin, and also avoids the problem that the extension length L of the probe 300 is too long, causing the probe 300 to retract into the outer shell 100 and resulting in excessive elastic deformation of the elastic element 400. As a result, the elastic force of the elastic element 400 pressing on the matsutake skin through the probe 300 is too great and can easily damage the matsutake skin.

[0063] refer to Figure 2 In some embodiments, the detection system further includes a travel direction limiter 500, which is connected to the housing 100 and has a limiting groove 510 extending along the moving direction of the probe 300. Alternatively, the housing 100 may have a limiting groove 510 extending along the moving direction of the probe 300. The probe 300 is movably inserted through the limiting groove 510, and the groove wall of the limiting groove 510 is used to limit the outer periphery of the probe 300, thereby preventing the movement path of the probe 300 from deviating and affecting the actual detection results.

[0064] In some embodiments, the housing 100 has an inner cavity, and a through hole 110 is provided on one side wall of the housing 100. The transmission member 600 and the elastic member 400 are disposed in the inner cavity. A portion of the probe 300 is displaced in the inner cavity, and one end of the probe 300 is exposed to the outside of the housing 100 through the through hole 110.

[0065] Among them, reference Figure 2The probe 300 may include a first segment 310 and a second segment 320 connected sequentially along the moving direction. The circumferential dimension of the first segment 310 is smaller than that of the second segment 320. For example, when the probe 300 is a cylindrical shaft structure, the diameter of the first segment 310 is smaller than the diameter of the second segment 320. When the probe 300 is a polygonal prism structure, the dimension of the first segment 310 perpendicular to the moving direction is smaller than the dimension of the second segment 320 perpendicular to the shaft, thus forming a two-segment structure with different thicknesses. The second segment 320 is movably connected to the housing 100 and is connected to the transmission member 600. The second segment 320 and the transmission member 600 can be connected and transmitted through a rack structure 330 and a gear structure, as described in the previous embodiment. Increasing the circumferential dimension of the second segment 320 helps to ensure the strength of the second segment 320 and improve the connection stability between the second segment 320 and the transmission member 600. One end of the first segment 310, opposite to the second segment 320, extends to the outside of the housing 100. As an example, the second segment 320 is movably inserted into the limiting groove 510, or the first segment 310 is movably inserted into the limiting groove 510, thereby restricting the probe 300 to move only along the extension direction of the limiting groove 510, preventing the probe 300 from tilting, which helps to ensure the movement stability of the probe 300, reduce the risk of jamming, and also prevent the movement path deviation from affecting the accuracy of the detection results.

[0066] In the detection device of this application embodiment, the elastic element 400 can be a cylindrical spring or a sheet spring, or other component capable of elastic deformation, providing elastic force to restore the probe 300 to its initial position. In some embodiments, the elastic element 400 has a hollow portion; as an example, the elastic element 400 can be a cylindrical spring. The first segment 310 passes through the hollow portion, and a connecting surface 340 is formed at the connection point of the first segment 310 and the second segment 320, which are of different sizes. Therefore, one end of the elastic element 400 can be connected to the connecting surface 340, and the other end can be connected to the outer shell 100, for example, to the inner wall of the outer shell 100 on the side with the through hole 110, facilitating the connection of the elastic element 400. The first segment 310 passing through the hollow portion of the elastic element 400 can limit the elastic element 400 and prevent the elastic element 400 from being misaligned.

[0067] The following provides a specific application example of using the detection device according to an embodiment of this application for matsutake mushroom quality detection (see reference). Figures 1 to 2Prepare the matsutake mushroom sample to be tested, ensuring its surface is clean and free of impurities. Select a smooth, flat area as the testing area. Place the testing device of this embodiment stably above the matsutake mushroom sample, align the exposed end of the probe 300 with the area to be tested, and manually apply appropriate force until the matsutake skin contacts the outer shell 100. At this time, the probe 300 moves upward under the resistance of the matsutake skin and maintains a fixed path movement under the action of the limiting groove 510. Different grades of matsutake mushrooms have different surface textures and deformations under stress, resulting in different movement distances for the probe 300. The upper end of the probe 300 has a rack structure 330, which meshes with the first gear ring 611 of the first gear 610, causing the first gear 610 to rotate clockwise by a certain angle. The first gear 610, through the second gear ring 612, drives the second gear 620 to rotate by a certain amplitude. The second gear 620 then drives the indicator 700 to rotate counterclockwise by a certain amplitude. The grade corresponding to the sub-region 210 of the display area 200 where the indicator 700 is located is the quality grade of the tested matsutake mushroom. After the test, the device is detached from the matsutake mushroom. Under the elastic force of the elastic element 400, the probe 300 returns to its initial position. The first gear 610 and the second gear 620 then drive the indicator 700 back to the zero position, at which point the next matsutake mushroom sample can be tested.

[0068] In the detection device of this application embodiment, the grade classification of each sub-region 210 of the presentation area 200 can be performed in the following manner: Matsutake mushrooms stored for different times are subjected to quality analysis and testing, including at least biochemical testing and non-destructive elasticity testing using the detection device of this application embodiment. The changes in matsutake mushroom quality evaluated by biochemical testing and non-destructive testing values ​​are recorded. The matsutake mushroom quality values ​​obtained by biochemical testing are compared with the elasticity data obtained by non-destructive testing using the detection device of this application embodiment, thereby classifying the quality grade corresponding to the elasticity data range. By obtaining the grading standard through biochemical test results, the subjectivity and inaccuracy of manual methods are avoided, enabling a relatively objective and accurate characterization of matsutake mushroom quality.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
