Problems solved by technology

[0006] However, due to the low absorption intensity, complex bands, and serious overlap in the near-infrared region, it is still difficult to directly identify natural products, and it cannot be effectively identified by the naked eye. Therefore, there are still certain limitations in using near-infrared spectroscopy for direct detection. limitation

Embodiment 1

[0041] Embodiment 1 The establishment of quick and easy propolis glue source variety method

[0042] 1. Sample collection Birch trees were collected from Jilin Province, eucalyptus trees from Guangxi Province, poplar trees from Henan Province, and propolis samples from rubber glue source were collected from Yunnan Province. Propolis samples from various glue sources constitute the sample group of glue source varieties, and the types of propolis from birch, eucalyptus, poplar, and rubber glue sources are assigned as 1, 2, 3, and 4, respectively.

[0043] 2. The near-infrared spectrum scanning of the sample uses the 2mm optical path solid fiber probe of the MPA Fourier transform near-infrared spectrometer of Bruker Company to scan each propolis sample, scan each sample 3 times, and take the average value. The detection parameters of the instrument: the scanning range is 4000~12500cm -1 , resolution 4cm -1 , the number of scans is 32 times. The near-infrared raw spectrum of th...

Embodiment 2

[0058] The application of embodiment 2 quick and easy propolis gum source variety method

[0059] 1. Sample collection

[0060] 6 samples of propolis with unknown glue sources were collected from the market, and the sample numbers were FJ1, FJ2, FJ3, FJ4, FJ5, and FJ6.

[0061] 2. Near-infrared spectrum scanning of samples

[0062] Scan each propolis sample with the 2mm optical path solid fiber probe of Bruker's MPA Fourier transform near-infrared spectrometer, scan each sample 3 times, and take the average value. The detection parameters of the instrument: the scanning range is 4000-12500cm -1 , resolution 4cm -1 , the number of scans is 32 times.

[0063] 3. Spectral data preprocessing

[0064] The near-infrared spectral data of propolis samples with unknown glue sources were imported into Matlab7.9.0 software, and spectral standardization preprocessing was carried out according to formula (1).

[0065] 4. Spectral data compression

[0066] The preprocessed near-infrar...

Abstract

The invention provides a method for rapidly identifying a propolis source. According to the method, a fingerprint characteristic spectrum of a near infrared spectrum is combined with chemometrics, so that the propolis source can be simply and rapidly identified. The method has the advantages of simple operation, rapidness, environment friendliness, low cost and the like.

Description

technical field [0001] The invention relates to a method for quickly identifying the source of propolis glue, which belongs to the technical field of chemical inspection, and specifically, belongs to the technical field of rapid food detection. Background technique [0002] Propolis (bee propolis) comes from hives and beehives. It is a viscous substance processed by bees from gums collected from plant sprouts and tree trunks, mixed with their own secretions, beeswax and pollen. A large number of studies have shown that propolis contains a variety of flavonoids, organic acids, a variety of amino acids, and trace elements. It has antibacterial, anti-inflammatory, antipruritic, analgesic, promoting tissue regeneration, lowering blood fat, and lowering cholesterol. It is a natural medicine , more and more recognized and utilized by people, propolis has become one of the important products of beekeeping production. [0003] Our country's glue source plant resources are relativel...
