ATR-FTIR combined with PCA and PLS1 models as a screening tool: performance in single-adulterant systems and limitations under multi-component conditions in UHT milk

Abstract The simultaneous adulteration of UHT milk with multiple compounds presents analytical challenges due to spectral overlap, matrix effects, and collinearity. This study evaluated ATR-FTIR spectroscopy combined with PCA and analyte-specific PLS1 models, aiming to screen for...
