Determination of Olive Oil Adulteration by Principal Component Analysis with HPLC–Charged Aerosol Detector Data

Overview Purpose: To examine the use of targeted principal component analysis (PCA) with HPLC-charged aerosol detector data as a means of determining adulteration of olive oils. Method: Oil samples were analyzed as both untreated and hydrolyzed, using a C30 HPLC method and charged aerosol detection. PCA results were determined using peak area percent values of the acylglycerides and free fatty ...

Prediction of fatty acid composition of vegetable oils based on rheological measurements using nonlinear models

The aim of this study was to model the fatty acid composition of vegetable oils by using the adaptive neuro fuzzy inference system (ANFIS) and artificial neural network (ANN) based on rheological measurements. For this aim, seven different refined vegetable oils (hazelnut, soybean, sunflower, olive, canola, corn, and cotton seed) were used. Olive oil had the highest viscosity value of 0.067 Pa ...

Quantification of underivatized fatty acids from vegetable oils by HPLC with UV detection.

We propose a chromatographic method for the separation of saturated and unsaturated fatty acids by a high-performance liquid chromatography system, equipped with a photo diode array detector. Central to the method is the use of an appropriate mobile phase composed of acetonitrile, methanol, and n-hexane in ratio 90:8:2 acidified with 0.2% acetic acid, which allows the detection of fatty acids w...

Determination of Polycyclic Aromatic Hydrocarbons in Olive and Refined Pomace Olive Oils using HPLC/FLD

ABSTRACT: In this study, an analytical method is developed to determine 15 polycyclic aromatic hydrocarbons (PAHs) in olive and refined pomace olive oils using HPLC coupled with a fluorescence detector. The standardised method of ultrasound-assisted solvent extraction consisted of liquid–liquid extraction with organic solvent and purification on C18 and Florisil bonded-phase cartridges was modi...

Application of Microwave Spectroscopy Analysis on Determining Quality of Vegetable Oil

Recently there has been an increasing interest in the classification of edible oils as an effective means to examine authenticity and to detect possible adulteration of virgin olive oils with seed oils or low-quality olive oils. Classical methods based on gas chromatography (GC) and high-performance liquid chromatography (HPLC) are too expensive for widespread industrial use and require samples...
