Gas chromatography-olfactometry (GC-O) can also be considered a method used for untargeted analyses, even though the information provided is different with respect to GC-MS. For such a reason, it is a common occurrence to split the column effluent between a mass spectrometer and an olfactometry port to attain complementary types of information (Delahunty et al., 2006). Again, the non-sufficient resolving power of a single GC column can hinder the attainment of reliable GC-O-MS essential oil information, calling for the use of a multidimensional (MD) GC method. However, the enhanced separation power of heart-cutting MDGC, and not GC × GC, is the preferred choice in such instances (Delahunty et al., 2006).

Linalool and linalyl acetate impart the olfactory notes of the oil or extract, and their content is considered an index of product quality (Statti et al. 2004; Perna et al. 2019). The use of gas chromatography-olfactometry-mass spectrometry has indicated that the distinct smells associated with different mixtures of Citrus fruits in black tea and their diverse flavors are due to the presence of compounds such as alkenes that vary according to the species of Citrus, and determine its aromatic characteristics (Wang et al. 2020).
