GC-MS, FTIR and Raman spectroscopic analysis of fatty acids of Pistacia vera (Greek variety "Aegina") oils from two consecutive harvest periods and chemometric differentiation of oils quality.
TL;DR: In this article, three chemometric models were developed for the two consecutive harvest years of Pistachio oil and the discrimination was based on GC-MS analysis, FTIR and Raman spectroscopic data combined with cross-validation techniques and comparison among them.

Rapid screening on aflatoxins' presence in Pistachia vera nuts using diffuse reflectance infrared Fourier transform spectroscopy and chemometrics.
TL;DR: It is expected that the present method may be proved useful in food industry and the inspection authorities as a rapid decision-making tool to detect batches that must be rejected and enhance consumers’ protection from aflatoxin contaminated pistachios.

Study of the Quality Parameters and the Antioxidant Capacity for the FTIR-Chemometric Differentiation of Pistacia Vera Oils.
TL;DR: This research highlighted the possibility of developing a simple, rapid, economic, and environment friendly method for the discrimination of pistachio oils according to their quality profile, through FTIR spectroscopy and multivariate analysis.

Study of volatile compounds in Greek pistachio (Pistacia vera L. ‘Aegina’ cultivar) oils using Soxhlet and ultrasound assisted extraction
TL;DR: In this paper , the differences in volatile profile of pistachio oils 'Aegina' cultivar extracted with two different techniques, ultrasound assisted extraction (UAE) and Soxhlet, were investigated.
