Article Synopsis
- - The study analyzed the optical and internal quality properties of stored potatoes at 25 °C, focusing on their absorption and scattering coefficients, as well as firmness, moisture content, and soluble solids.
- - Storage time significantly affected potato tissue structure, leading to changes in optical properties; increased scattering and strong correlations were found between absorption coefficients and moisture/soluble solids content, while scattering coefficients correlated with firmness.
- - Advanced statistical techniques, specifically the CARS algorithm, enhanced prediction accuracy for various models, indicating that potato optical properties can be effectively used to predict their internal quality.
The quantitative determination of the soluble solid content (SSC) of potatoes using NIR spectroscopy is useful for predicting the internal and external quality of potato products, especially fried products. In this study, the effect of peel on the partial least squares regression (PLSR) quantitative prediction of potato SSC was investigated by transmission and reflection. The results show that the variable sorting for normalization (VSN) pre-processing method improved model accuracy.
