Assessment of Maturity of Plum Samples Using Fourier Transform Near-Infrared Technique Combined with Chemometric Methods
The FT-NIR technique was used for rapid and non-destructive determination of plum ripeness. The dry matter (DM), titratable acidity (TA), total soluble solids (TSS) and calculated maturity index (MI: TSS/TA) were used as reference values. The PLS correlations were validated via five-fold cross-valid...

| description | The FT-NIR technique was used for rapid and non-destructive determination of plum ripeness. The dry matter (DM), titratable acidity (TA), total soluble solids (TSS) and calculated maturity index (MI: TSS/TA) were used as reference values. The PLS correlations were validated via five-fold cross-validation (RMSECV for different parameters: DM: 0.66%, <i>w</i>/<i>w</i>; TA = 0.07%, <i>w</i>/<i>w</i>; TSS = 0.72%, <i>w</i>/<i>w</i>; MI = 1.39) and test set validation (RMSEP for different parameters: DM: 0.65%, <i>w</i>/<i>w</i> TA = 0.07%, <i>w</i>/<i>w</i>; TSS = 0.61%, <i>w</i>/<i>w</i>; MI = 1.50). Different classification algorithms were performed for TA, TSS and MI. Linear, quadratic and Mahalanobis discriminant analysis (LDA, QDA, MDA) were found to be the best sample detection methods. The accuracy of the classification methods was 100% for all investigated parameters and cultivars. |
