Abstract

Two different kinds of soybean oil were adulterated with a low-quality “hogwash” oil, extracted from oxidized oils and other leftovers. Adulterated mixtures with hogwash concentrations ranging from 5 to 75 % were prepared and analyzed by means of absorption spectroscopy in the visible range. Another mixture set was prepared for validation purposes. All spectra were first analyzed by means of Principal Component Analysis (PCA) for explorative purposes. Then, for each soybean oil, a dedicated Partial Least Square (PLS) model was created for quantitative determination of adulterant concentration. Very good results were obtained with one-factor PLS models, giving determination coefficients higher than 0.99 and Root Mean Square Errors ranging between 1 and 2.5 % in both calibration and validation.
