Abstract: The objective of this study was to establish a mathematical model for quantitative determination of total phenols of Actinidia arguta using the near-infrared diffuse reflectance (NIR) spectra in the wavelength range of 570–1848 nm. The experiment was divided into three stages to set the model (harvest stage, storage of 12 days, storage of 24 days), and compared with the different modeling methods. The results showed that the partial least squares (PLS) model, with respect to the first order derivatives spectrum D1 lg(1/R) and inverse multiple scatter correction(IMSC)treatment, provided better predictive performance for total phenols in Actinidia arguta. In calibration sample set, the correlation coefficient of cross validation (RCV) was 0.8939, and root-mean-square error of cross-validation (RMSECV) was 11.6734 mg/100 g. In prediction set sample, the correlation coefficient of prediction (RP) was 0.8627, and root-mean-square error of prediction (RMSEP) was 16.7690 mg/100 g. These results confirmed that it is feasible to use the established VIS/NIR spectroscopy model for the nondestructive determination of the total phenols in Actinidia arguta. However, further investigation is needed to improve the precision of the model.
