The NIRS instrument used in this study is the CvSU InGaAs-based NIR instrument. This instrument is a patent pending, NIRS instrument developed by engineers, scientists and professors from Cavite State University that is based on Indium Gallium and Arsenic (InGaAs) NIRS sensor. It can obtain the absorbance **data** in the range of 950 to 1684 nm. The technique used in this study is the single seed NIR spectra acquisition as described in [43], where a single bean is placed in the scanner of CvSU In GaAs-based NIR instrument. The instrument was allowed to warm-up for a period of at least 30 minutes so that the light output and electronics related to spectrometer would stabilize prior to spectra collection. After warming up the instrument, the spectral precision for the two groups of sample was determined. This was done by scanning ten different samples (re-loaded group) of civet coffee and the tenth sample scanned for another ten times (non-reloaded group).
