“…However, it is usually difficult to determine the molecular source of each peak due to the complex composition of edible oils [ 17 ]. Consequently, multivariate calibration methods combined with FTIR spectroscopy are used to analyze this complex information [ 18 , 19 , 20 ]. Rohman et al [ 21 , 22 , 23 ] used FTIR spectroscopy coupled with PLS and PCR to establish models for the quantitative analysis of binary and ternary oil blends.…”

Edible oil blends are composed of two or more edible oils in varying proportions, which can ensure nutritional balance compared to oils comprising a single component oil. In view of their economical and nutritional benefits, quantitative analysis of the component oils in edible oil blends is necessary to ensure the rights and interests of consumers and maintain fairness in the edible oil market. Chemometrics combined with modern analytical instruments has become a main analytical technology for the quantitative analysis of edible oil blends. This review summarizes the different oil blend design methods, instrumental techniques and chemometric methods for conducting single component oil quantification in edible oil blends. The aim is to classify and compare the existing analytical techniques to highlight suitable and promising determination methods in this field.

“…The official European Union (EU) classification implemented for defining oil authenticity and quality are “Protected designation of origin” (PDO) and “Protected geographical indication” (PGI) ( EEC, 1992 ). Many studies have been carried out and published on validating the endogenous species as markers of origin of monovarietal oils by many analytical approaches, such as NMR ( Mannina et al, 1999 ; Sacchi et al, 1998 ), FT-IR ( Amit et al, 2020a , 2020b , 2020c ) and GC ( Benincasa et al, 2003 ).…”

“…Multivariate chemometrics has been exceedingly implemented recently for the analysis of various adulterants in coconut oil ( Amit et al, 2020a , 2020b , 2020c ). But for geographical identification of different edible oils, there are very few cases where multivariate chemometrics has been applied so far.…”

“…Nevertheless, other robust approaches are being applied, as the Principal Component Regression (PCR) [32][33][34][35][36]. PCR can be understood with exactly two steps, the first is the application of the PCA and soon after the regression which will provide the main components for a new explanatory variable in the model [37].…”

Dosimetric evaluation is indicated for material characterization seeking to identify possible applications; still, proper preprocessing techniques are critical features of this process. This work aimed to determine the linearity response of plastic samples irradiated with gamma rays using the Fourier Transform Infrared (FTIR) measurements. The plastic samples were analyzed using Derivatives and Principal Component Analysis (PCA) methods. They applied linear and Principal Component Regression (PCR) methods to obtain linearity. The methods obtained good results for linearity and also showed the evolution of each technique. In conclusion, the results indicate that the applied methods can be useful in radiation physics and for plastic samples as interesting potential radiation detectors.
