“…The details of functional groups responsible for FTIR absorption bands are described in Table 1. In our study, the spectra of these oil samples showed many similarities among absorbance bands, which is consistent with previous reports [10,27,30,[36][37][38]. All plant oils are made up of triacylglycerol (92%), low concentrations of di-and mono-acylglycerols (5%), and low levels of other components [23].…”

“…Due to its valuable composition and related properties, CAO is gaining popularity as a food, and in pharmaceuticals and cosmetics. These oils are relatively expensive because of their nutritional values, and thus it is important to protect them from adulteration with low price/quality edible oils such as RSO, SBO, SFO, CO, and peanut oil (PO) [8][9][10][11]. Moreover, rapeseed and derivatives such as RSO are recognized as a new potential source of allergies [12].…”

“…Recent advances in physical technologies have also enabled rapid analytical systems that do not require sample preprocessing and therefore induce less chemical waste. For example, Fourier transform near infrared (FT-NIR) had been used with PLS1 in the detection of extra virgin olive oil adulteration 28 , Low-field nuclear magnetic resonance (LF-NMR) was used with discriminant analysis (DA) for the binary classification of adulterated peanut oil 29 , proton nuclear magnetic resonance was used with PLS1 for the detection of Camellia oil 30 and excitation–emission matrix fluorescence spectroscopy had been used with N-way PLS for the detection of Camellia oil 31 . However, these studies also used traditional chemometric techniques and did not study the generalizability of their models across a large diverse set of samples.…”

“…Partial Least Square Discriminant Analysis is a linear classification method that is based on the PLS regression algorithm [8,16]. This method is a combination of properties of partial least squares regression and the discrimination power of classification technique.…”
