Abstract

Abstract: In recent decades, the development of fast, non-destructive and robust methods to determine agricultural products quality parameters become interesting and gaining more attentions in term of their potential applications in many field. One of those methods is near infrared spectroscopy (NIRS) which is works based on the interaction of biological matter with light radiation. The main purpose of this present study is to employ the NIRS method in assessing mango fruit quality parameters in form of soluble solids content (SSC) and vitamin C. Spectra data of absorbance NIR were acquired in wavelength range from 1000 to 2500 nm with optical gain 4x and resolution windows 0.02 nm. Prediction models were developed using partial least square regression (PLSR) followed by 10-fold cross validation. The results showed that both SSC and vitamin C of mango fruit can be determined simultaneously with maximum correlation coefficient are 0.88 and 0.87 for SSC and vitamin C respectively. Judging from its predictive abilities, it may conclude that NIRS can be used as fast and contactless method in assessing mango fruit quality parameters like SSC and vitamin C.
