Embodiment 1

[0037] Such as figure 1 It shows a schematic diagram of the implementation flow of a method for identifying orange peel provided by an embodiment of the present invention. The method is applied to an identification system for orange peel and is suitable for situations where it is necessary to improve the identification accuracy of orange peel varieties and storage years, including steps 101 to 10. 103.

[0038] Step 101, obtaining a sample of tangerine peel to be identified.

[0039] In the embodiment of the present invention, the tangerine peel sample to be identified is a tangerine peel sample that can directly collect terahertz spectral signals after pretreatment.

[0040] Different terahertz spectrometers have different pretreatment methods for raw tangerine peel samples.

[0041] Since the terahertz wave has a very strong sensitivity to water, when obtaining the terahertz spectral information of the tangerine peel sample to be identified, it is easily affected by the mo...

Embodiment 2

[0063] This embodiment further defines step 102 in the first embodiment above.

[0064] Optionally, in the above step 102, the use of a terahertz spectrometer to obtain the terahertz spectrum information of the tangerine peel sample to be identified may include: using a terahertz spectrometer including a transmission module to obtain the terahertz spectrum of the tangerine peel sample to be identified signal, and perform signal processing on the terahertz spectral signal to obtain the terahertz spectral information of the orange peel sample to be identified.

[0065] Such as image 3 As shown, the transmission module can include an optical integrating sphere body 3, an incident window 3-1 and an exit window 3-2 arranged on the optical integrating sphere body, and a detachable transmission module matched with the optical integrating sphere body. The sample placement rack 3-3; the detachable transmission sample placement rack 3-3 is used to place the orange peel sample to be id...

Embodiment 3

[0099] Compared with the second embodiment above, this embodiment provides a terahertz spectrometer including another transmission module.

[0100] Such as Figure 5 As shown, the transmission module 51 may include a sample chamber 511 and a stage 512 placed on the sample chamber 511; the stage 512 is used to place the orange peel sample to be identified.

[0101] The terahertz spectrometer includes: a laser light source 52, a beam splitter 53, a terahertz radiation antenna 54 and a terahertz detection antenna 55;

[0102] The use of a terahertz spectrometer to obtain the terahertz spectral information of the orange peel sample to be identified includes:

[0103] The laser light emitted by the laser light source 52 is divided into probe light and pump light by the beam splitter 53; the probe light enters the terahertz detection antenna 55; the pump light irradiates the terahertz radiation antenna 54 to emit a terahertz wave; the terahertz wave enters the sample chamber 511 o...

Abstract

The present invention is applicable to the technical field of dried tangerine peel identification, and provides an identification method and an identification system of dried tangerine peel. The identification method comprises that a sample of dried tangerine peel to be identified is obtained; terahertz spectroscopy information of the dried tangerine peel sample to be identified is obtained by using a terahertz spectrometer; and according to the terahertz spectroscopy information of the dried tangerine peel sample to be identified, the variety and storage period of the dried tangerine peel sample to be identified are determined by using the terahertz spectroscopy difference information of pre-obtained dried tangerine peel with different varieties and storage periods. The accurate identification of dried tangerine peel variety and storage period is realized, and the technical problems that the obtained information of the dried tangerine peel sample is single and the variety and storageperiod of dried tangerine peel cannot be accurately determined are solved.

Description

technical field [0001] The invention belongs to the technical field of tangerine peel identification, and in particular relates to an identification method and an identification system for tangerine peel. Background technique [0002] Tangerine peel belongs to the Rutaceae citrus genus, which contains flavonoids such as hesperidin, nobiletin and tangeretin and other volatile oils. Its finished products or extracts are widely used in cosmetics, food and medicinal materials. The place of origin, variety, preparation process and storage period of tangerine peel have a great influence on its composition and quality. The longer the storage time, the more precious the tangerine peel is, and the better its medicinal effect is, so it is said that "the old one is good". . In addition, among the tangerine peels, Guang tangerine peel is the best, especially the tangerine peel produced by Guangdong Xinhui is the top grade. Due to the high price of old Guang tangerine peels in high yea...
