Abstract: This work describes the novel approach for the quantitative description of sugar profiles in peaches during storage by using single-integrating sphere (SIS). The spectral profiles for the optical properties (light absorption coefficient μa and reduced scattering coefficient μ s) were measured. Correlation analysis between the optical properties and the sugar profiles showed that higher correlated values, with r > 0.640, were found. Furthermore, quantitative models were constructed by partial least squares regression (PLSR) based on μa and μ s datasets to predict the sugar composition in peach flesh. The predicted results for the sucrose content based on μa datasets by PLSR were better (Rp2 = 0.796 at wavelengths of 600 to 1050 nm) than those based on the μ s datasets. The models established by SIS present a simple and efficient strategy for quantitative analysis and may be used as alternative methods for evaluating the quality attributes of different types of fruit.
