“…Such an approach is named UT fingerprinting. , In this application, analyte targeting (i.e., identification) was performed as the last step, before data mining. A schematic workflow of the UT fingerprinting strategy is reported in reference literature by Cordero and Reichenbach. − …”

In this study, the complex volatilome of maize silage samples conserved for 229 d, inoculated with Lentilactobacillus buchneri (Lbuc) and Lacticaseibacillus paracasei (Lpar), is explored by means of advanced fingerprinting methodologies based on comprehensive two-dimensional gas chromatography and time-of-flight mass spectrometry. The combined untargeted and targeted (UT) fingerprinting strategy covers 452 features, 269 of which were putatively identified and assigned within their characteristic classes. The high amounts of short-chain free fatty acids and alcohols were produced by fermentation and led to a large number of esters. The impact of Lbuc fermentation was not clearly distinguishable from the control samples; however, Lpar had a strong and distinctive signature that was dominated by propionic acid and 1-propanol characteristic volatiles. The approach provides a better understanding of silage stabilization mechanisms against the degradative action of yeasts and molds during the exposure of silage to air.

“…In addition, the combination of Eucalyptus citriodora oil with mint oil causes the released aroma to become stronger. As stated by Gabetti et al of the 95 types of active compounds identified using gas chromatography-olfactometry, the strongest ones were the eucalyptus, fresh, camphoraceous flavors Minute from 1,8-cineole (Eucalyptus oil), and the minty, musty, and herbaceous flavors from menthone (peppermint oil) [17]. The strong aroma and flavor released from the volatile compounds of Eucalyptus oil and peppermint oil have the potential to be used as aromatherapy.…”

Eucalyptus citriodora oil is an essential oil that contains volatile active compounds. To slow down the process of releasing such volatile compounds, a binding agent such as a polymer matrix is needed. This research aimed to prepare and characterize the properties of Eucalyptus citriodora oil encapsulated in polymer matrices. Development of nanoencapsulated Eucalyptus citriodora was prepared using the melt-dispersion method and polymer matrices (PEG-6000 and paraffin wax) with the addition of Mentha piperita oil as aroma enhancer at a ratio of 1:1. The gas chromatography analysis showed that Eucalyptus citriodora oil contains volatile compounds (citronellal 76.17%). The nanoencapsulated eucalyptus powder produced using the PEG-6000 matrix, in terms of properties, was better than that using paraffin for having smaller particle size and being difficult to agglomerate at room temperature. The average size of oil droplets of nanoencapsulated Eucalyptus citriodora in the PEG-6000 matrix was 235.35 nm with a PDI of 0.339. The morphological analysis using a transmission electromagnetic microscope indicated that the average droplet size was less than 100 nm. This product can be used as a breath-relieving aromatherapy powder by wrapping it in porous paper to be inhaled.

“…To the best of the authors' knowledge, the first application of GCxGC to EO analysis was on vetiver (Chrysopogon zizanioides (L.) Roberty) EO performed by Marriot's group [57]; since then, several GC × GC applications in the EOs analysis have been reported in the literature [among others 54,[58][59][60][61][62][63][64][65][66][67][68][69], showing the great potentiality of this technique, in particular when EOs are characterized by hundreds of components (i.e., C. zizanioides (L.) Roberty) or when they contain components with very similar structure and therefore difficult to separate in a single run (e.g., sandalwood, Santalum album L.), but decisive to define product quality and authenticity or to characterize a species.…”

This review is an overview of the recent advances of gas chromatography in essential oil analysis; in particular, it focuses on both the new stationary phases and the advanced analytical methods and instrumentations. A paragraph is dedicated to ionic liquids as gas chromatography stationary phases, showing that, thanks to their peculiar selectivity, they can offer a complementary contribution to conventional stationary phases for the analysis of complex essential oils and the separation of critical pairs of components. Strategies to speed-up the analysis time, thus answering to the ever increasing request for routine essential oils quality control, are also discussed. Last but not least, a paragraph is dedicated to recent developments in column miniaturization in particular that based on microelectromechanical-system technology in a perspective of developing micro-gas chromatographic systems to optimize the energy consumption as well as the instrumentation dimensions. A number of applications in the essential oil field is also included.
