“…The application of chemometric methods is a common and effective way to classify food materials (Bosque-Sendra et al, 2012;Zhang et al, 2012). LDA, for instance, was used to exploit invisible changes of the internal characteristics of blanched sweet corn yielding satisfactory classification rate of 94.3% and performed well in firmness prediction of processed sweet corn (Shao and Li, 2010).…”

“…A stepwise technique, using the Wilks' λ method with the usual probabilities of F (3.84 to enter and 2.71 to remove), was applied for variable selection. This procedure uses a combination of forward selection and backward elimination procedures, where before selecting a new variable to be included, it is verified whether all variables previously selected remain significant (Bosque-Sendra et al, 2012). With this approach, it is possible to identify the significant variables obtained for each sample.…”

“…The profiles of fatty acids (Cava et al, 1997, Flores et al, 1988, Ruiz et al, 1998, triacylglycerols (Díaz et al, 1996, NarváezRivas et al, 2009, VieraAlcaide et al, 2007, hydrocarbons (VieraAlcaide et al, 2009;Gamero Pasadas et al, 2006;NarvaézRivas et al, 2008) and volatile compounds (NarvaézRivas et al, 2010(NarvaézRivas et al, , 2011 have been related with the fattening diets of Iberian pigs and can be used as chemical descriptors to differentiate among the different feeding backgrounds of the animals. Nearinfrared spectrometry (NIR) is another method that has been used for the authentication of this animal fattening diet (Arce et al, 2009;Hervás et al, 1994;Zamora Rojas et al, 2011.…”

“…Jurado, i. viera-alcaide, F. Pablos aNd M. leóN-caMacho al., 2008) and between extensive and intensive systems (Gallardo et al, 2012). Previously, the triacylglycerol profile has been extensively used for the characterization and authentication of several foodstuffs such as olive oil, vegetable oils, animal fats, fish oils, milk and dairy products, cocoa and coffee (BosqueSendra et al, 2012;González et al, 2001).…”

“…These methods include chromatographic techniques (Bosque-Sendra et al, 2012;Baccouri et al, 2008) and spectroscopic techniques, such as mass spectrometry (Calvano et al, 2012), Nuclear Magnetic Resonance (NMR) (Fragaki et al, 2005), near-infrared spectroscopy (Mignani et al, 2011), Raman spectroscopy (Dong et al, 2012), chemiluminescence (Papadopoulos et al, 2002), fluorescence spectroscopy (Sikorska, Khmelinskii & Sikorski, 2012), and synchronous fluorescence (Poulli, Mousdis & Georgiou, 2007). This study focuses on the detection and quantification of adulteration of extra-virgin olive oil with edible oils, using a combination of LED-induced spectrofluorimetry and chemometrics.…”
