Summary: The wavelengths associated with firmness, soluble solids, and titratable acidity were identified in the microwave spectra region. A positive correlation was achieved for the three quality parameters with a varying prediction power range. The strongest correlation was found for titratable acidity, followed by firmness and soluble solids concentration. The narrow distribution range affected the prediction of soluble solids, but the MAE and Bias are low, indicating a low error between the prediction and the observed value. Overall, the results are promising, but more data is needed to evaluate the instrument's accuracy.
