Abstract

In this research, the feasibility of using NIR spectroscopy coupled with forward interval partial least squares (FiPLS) regression for nondestructive soluble solids content (SSC) determination in Pondoh snake fruit was investigated. Spectra of snake fruit were acquired using a VIS-NIR USB4000 portable spectrometer in absorbance mode. The SSC was measured using a digital refractometer.  The calibration and validation models were developed using the FiPLS regression using original spectra. The result showed that the optimal combinations of 7 spectral intervals among 11 intervals which selected by FiPLS yielded good results (RMSEC = 0.854783%, rc= 0.96, RMSECV = 0.899828%, rv = 0.95).  Keywords: soluble solids content, absorbance mode, nondestructive method, snake fruit, FiPLS regression, NIR spectroscopy

Abstract

In this research, the potentiality of using NIR spectroscopy and chemometrics for nondestructive determination of blood oranges flesh was investigated. Spectra of intact blood oranges fruit were acquired using a VIS-NIR MMS1 portable spectrometer in absorbance mode. The RGB of blood oranges cut flesh was measured using image processing software.  The calibration and validation models were developed using PLS regression using original spectra. The calibration results showed that the developed calibration models were promising with correlation r=0.82 for red component (R) determination and r=0.81 for green component (G) determination, respectively. Keywords: blood oranges, NIR spectroscopy, RGB color, absorbance mode, nondestructive method
