• classified by the FTIR–PCA technique [4]. In other studies, PCA was coupled with GC–MS for the classification of β-CD/Ocimum basilicum L. essential oil complexes and raw and thermally processed Mangalitza (Sus scrofa domesticus) lipid fractions, as well as for the discrimination of organic apples (Malus

• Ocimum basilicum L. essential oil and its β-cyclodextrin (β-CD) complex have been investigated with respect to their stability against the degradative action of air/oxygen and temperature. This supramolecular system was obtained by a crystallization method in order to achieve the equilibrium of complexed

• derivatives (2-hydroxypropyl-β-CD, randomly and low methylated β-CD) with good formation constants of almost 1000 M–1 for β-CD [46]. In this study, the evaluation of the protection capacity of natural β-CD for the main labile compounds of basil (Ocimum basilicum L.) essential oil under thermal and oxidative
