Development of Methods for the Classification of Vegetable Oils According to Their Botanical Origin

subject

description

The aim of this work was to construct an LDA model able to classify vegetable oils according to their botanical origin using FTIR spectroscopy data. Also, FTIR data treatment by MLR was used to detect and quantify EVOO adulteration with other low cost edible oils. For these purposes, the vegetable oils shown in Table 5.1 were used. The FTIR spectra of these 30 oil samples were then measured. In all cases, at least two spectra were recorded for each sample. As indicated in this table, four samples of each botanical origin were used to construct a training set in the classification studies, while the remaining samples of each category were employed to evaluate the prediction capability of the classification models.
