Cromatografia gasosa quiral na resolução de enantiômeros envolvidos em flavours de frutas

This work addresses the use of chiral gas chromatography in resolving optically active stereoisomers and racemates found in fruit flavours. It presents the types of chiral selectors applied to terpene-derived metal coordination compounds, polysiloxane-linked α-amino acid and mixed chiral stationary phases, and focuses on derivatized cyclodextrins, the most popular chiral stationary phases presently used in chromatographic analysis. Knowledge about the techniques involved in chiral recognition and enantiomer identification in the fruit flavour field is given along with examples from the latest studies.
