Abstract

Visible/Near Infrared Speciroscopy (Vis/NIR) appears as a prominent technique for nondestructive fruit quality assessment. This research work was focused in to evaluate the use of Vis/NIRS in measuring the quality characteristics of intact Fuji apple (from Shanxi of China), and the relationship was established between nondestructive Vis/NIR spectral measurement and the soluble solids content of apple. Intact apple fruit were measured by reflectance Vis/NIR in 325-1075 nm range. The data set as the logarithms of the reflectance reciprocal (absorbance (logl/R)) was analyzed in order to build the best calibration model for this characteristic, using some spectral pretreatments and multivariate calibration techniques such as partial least square regression (PLS). The models for the SSC (r =0.862), standard error of prediction (SEP) 0.907 with a bias of 0.599; shown the reasonable prediction performance. The Vis/NIR spectroscopy technique had significantly accuracy for detennining the SSC. It was concluded that the Vis/NIRS measurement technique seems reliable to assess the soluble solids content of apple non-destructively.
