[0012] Example
[0013] 1Materials and methods
[0014] 1.1 Material
[0015] 121 samples of mature peppers from the Chinese Academy of Agricultural Sciences. Among them, 93 samples are calibration sets, and 28 samples are verification sets. The capsaicin content is 0.406mg / g~6.71mg / g.
[0016] 1.2 Instruments and equipment
[0017] NIRLab N-200 near infrared quality analyzer, Buchi, Switzerland (NIRCalV4.21 software, 12cm sample cup).
[0018] 1.3 method
[0019] 1.3.1 Sample pretreatment
[0020] Crush the dried chili sample together with the seeds and skins, pass a 40-mesh sieve, and spread the chili powder over the sample cup with a thickness of not less than 1 cm.
[0021] 1.3.2 Near-infrared spectrum collection
[0022] At room temperature, measure the near-infrared diffuse reflectance spectrum of the pepper powder sample. When measuring, the resolution is 1cm -1 , The number of scans is 3, and the spectrum range is 1100~2500nm. After preheating the instrument for 20-30 minutes, pl...
