Abstract

The photodiode array (PDA) spectrometer combined with partial least square (PLS) was developed to rapid measure the internal quality indices of Gannan navel orange nondestructively in the wavelength range of 550-950nm. The original spectra were processed by standard normal variate (SNV) and Savitzky-Golay (SG) smooth method. The optimal models of internal quality indices were determined after different spectral windows chosen. The optimal model of soluble solids content (SSC), total acidity (TA) and ratio of them were developed with RMSECV = 0.5118Brix%, 0.0856% and 2.0617 by PLS method, respectively. The optimal spectral windows were 700-950nm, 600-750nm and 600-950nm for measuring internal indices nondestructively by PDA. The results illustrated that PDA with PLS method were a rapid tool to measure the internal quality indices of Gannan navel orange nondestructively.
