doi: 10.3390/molecules27238208
Figure Lengend Snippet: Overview of the experimental procedure of this research. Transformations using green coffee beans (MT) (left) and various agricultural samples (right). X SL,MT and X MS,MT represent the NIR spectra of the coffee samples (MT), respectively, which were used as the slave and master data for the PDS transformation. X SL and X MS represent the NIR spectra of the other agricultural samples obtained from the homemade and NIRSystem 6500 spectrometers. X SK : X YP : X NK represent the NIR spectra of the coffee samples (SK, YP, and NK) recorded using the homemade instrument.
Article Snippet: For the reference NIR system, a Foss NIRSystem 6500 (Foss NIR Systems, Silver Spring, MD, USA) benchtop instrument was used.
Techniques: Transformation Assay
