Non Destructive Prediction of Ripe-Stage Quality of Mango Fruit Cv 'Gedong Gillen' Stored in Low Temperature by NIR Spectroscopy

Abstract

This study demonstrates the use NIR spectroscopy to predict the internal quality parameter in mango fruit non destructively. Soluble solids content (SSC). pH and firmness of mango fruits cv: ‘Gedong Gincu') were examined by NIR reflectance to find out factors to be considered in online detection. The wavelength range of 1000-2400 11m was selected and data pre-processing was used to enhance the precision of calibration models based all partial least square (PLS).The coefficient of correlation (r) of SSe. pH and firmness were 0.756. 0.94 and 0.89. and the stnndard error of prediction (SEP) were 2.014 ◦Brix, 0.157 and 0.63 kgf. respectively. It is concluded that by using the NIR measurement system. in the appropriale spectral range. it is possible to non destructively predict the ripe-slage quality of mango fruit i.e. SSe. pH and firmness.
