Description

Technical Field

[0001] The invention relates to the technical field of food detection, in particular to a device for detecting the capsaicin content in pepper fruits. Background Art

[0002] Pepper is an important economic crop of the genus Capsicum in the Solanaceae family. With the continuous increase in the number of people who eat spicy food and the continuous expansion of the consumer market, consumers have increasingly higher requirements for the spicy characteristics of peppers, and are no longer satisfied with simple classifications such as "mildly spicy" and "spicy". Both producers and consumers are in urgent need of more clear and quantitative spiciness indicators. The spiciness of peppers mainly comes from capsaicin, and its content directly determines the spiciness intensity and quality of peppers, and is the key basis for evaluating the quality of peppers. Therefore, accurate and rapid detection of capsaicin content is crucial to the development of the pepper industry.

[0003] At present, the detection of capsaicin mainly relies on high performance liquid chromatography (HPLC). Although HPLC has high detection accuracy, it has many disadvantages, such as: the equipment is expensive, which makes the detection cost high; the instrument is bulky and not convenient to carry and use on site; the operation is complicated and requires professional technicians to operate and maintain, which greatly limits its application in large-scale pepper production and consumption markets and cannot meet the demand for convenient detection technology.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The purpose of the present invention is to provide a device for detecting the capsaicin content in pepper fruit, so as to solve the problems existing in the above-mentioned prior art and facilitate the detection of the capsaicin content in pepper.

In the present invention, peppers with different diameters will correspond to different diameter grades, and for different diameter grades, there will be different near-infrared spectroscopy prediction models of the capsaicin content, so accurately obtaining the diameter data is helpful to improve the accuracy of the calculation of the capsaicin content; A light emitting module is disposed in the shell 1, and the light emitting module includes a near-infrared light source 4, a driving device 5, a first fixed rod, a second fixed rod, a third fixed rod, a tension spring 16 and a traction line 17. The first fixed rod, the second fixed rod and the third fixed rod are spaced from top to bottom and are respectively fixedly connected to the inner wall of the shell 1 at one end. The near-infrared light source 4 is hinged to the other end of the first fixed rod, one end of the tension spring 16 is connected to the other end of the second fixed rod, and the other end is connected to the near-infrared light source 4. The driving device 5 is fixed at the other end of the third fixed rod, one end of the traction line 17 is connected to the near-infrared light source 4, and the other end is wound around the output shaft of the driving device 5.

[0025] The spectrometer 6 is arranged in the shell 1 and connected to the shell 1. The spectrometer 6 is used to split the near-infrared light reflected by the pepper to be detected; through spectroscopic processing, the mixed near-infrared light can be decomposed into light of different wavelengths, which is convenient for the subsequent detection probe 7 to more accurately receive and analyze the optical signal, thereby providing more detailed spectral information for accurate detection of capsaicin content.

It is worth noting that for different diameters of peppers, there are corresponding emission angles of near-infrared light. After detecting the diameter of the pepper, the central controller 14 controls the driving device 5 to drive the near-infrared light source 4 to rotate to the required angle; and the corresponding relationship between the angle of the near-infrared light source 4 and the rotation output of the driving device 5 (that is, the corresponding relationship between the angle of the near-infrared light source 4 and the winding length of the traction line 17) needs to be obtained by a large number of tests in advance after the device is assembled, and is programmed in the central controller 14 to achieve accurate control of the angle of the near-infrared light emitted by the near-infrared light source 4.

And the built-in power supply 9 adopts a battery. Using a battery as the built-in power supply 9 enables the detection device to have an independent power supply capability without relying on an external power supply, thereby enhancing the portability and flexibility of the device, and facilitating the detection of capsaicin content in different places.

[0033] In the optional scheme of this embodiment, it is more preferred that the near-infrared light source 4 can emit near-infrared light with a wavelength of 900nm to 1700nm. The near-infrared light in this wavelength range matches the absorption characteristics of capsaicin in peppers, and can more effectively stimulate the absorption and reflection of near-infrared light by capsaicin, thereby obtaining more accurate spectral information and improving the accuracy of capsaicin content detection.

[0034] In the optional scheme of this embodiment, it is more preferred that there are two light emitting modules, and the two light emitting modules are located on both sides of the detection probe 7. This design can irradiate the pepper with near-infrared light from different angles, further improve the light coverage of the pepper surface, and obtain more comprehensive reflected light information, thereby more accurately detecting the capsaicin content and improving the reliability of the detection results.

The user can manually operate and set parameters of the detection device through the control buttons 11, such as starting or stopping detection, adjusting the intensity, angle and other parameters of the near-infrared light source 4, thereby increasing the convenience and flexibility of the operation of the detection device and meeting the needs of different users and different detection scenarios.

[0036] In the optional scheme of this embodiment, it is more preferred that the detection probe 7 adopts a 128-line element uncooled InGaAs diode array detector.

[0041] It should be noted that the near infrared spectroscopy prediction model of capsaicin content is a prior art in the art, so this embodiment will not elaborate on how to establish the near infrared spectroscopy prediction model of capsaicin content and its principle. In addition, in this embodiment, since peppers with different diameters have differences in the distribution and detection of capsaicin content, different diameter grades are divided according to the different diameters of peppers in this embodiment, specifically: Level 1: diameter <1cm; Level 2: 1cm≤diameter<2cm; Level 3: 2cm≤diameter<3cm; Level 4: 4cm≤diameter<5cm; Level 5: diameter ≥5cm; For different diameter grades, different near-infrared spectroscopy prediction models for capsaicin content need to be set up, that is, the near-infrared spectroscopy prediction model for capsaicin content corresponds to the diameter grade of pepper one by one, so accurately obtaining diameter data helps to improve the accuracy of capsaicin content calculation.

In summary, the content of this specification should not be understood as limiting the present invention.
