Table 5 summarizes the most important applications of this technique within food safety and quality [7, 41, 106, 129–157]. The great analytical strength of GC lies in its high resolution. This means that the average capillary column (30 m long) has approximately 100,000 theoretical plates. GC-MS has been widely used within food quality and safety for: analysis of target compounds, target and nontarget metabolomics, and l importantly, profiling of volatile compounds. 1 Target Analysis This technique is still one of the answers to screen/identify and quantify many groups of moderately polar and nonpolar food components, contaminants, and residues [129].

1 A standard operating procedure, based on the combination of two successive SPE, was developed for various liquid and solid foodstuffs. The derivatization step consisted in a silylation reaction of bisphenol A using MSTFA.

[138] Residues Pesticide Fruits and vegetables LP-GC-TOF-MS (low resolution) GC-MS exhibited larger matrix effects, but as in LC-MS/MS, the differences were reasonably consistent among the 20 samples tested.

Agnus-castus fruits were analyzed under the same chromatographic conditions of the crude extract. Principal component analysis (PCA) based only on the variation of the amount of the seven chemical markers was applied in order to find similarities between the hydroalcoholic extract and the food supplements [50]. A second PCA analysis was carried out considering the whole spectroscopic data deriving from LC-ESI-LTQ-MS analysis. High similarity between the two PCA was observed, showing the possibility to select one of these two approaches for future applications in the field of comparative analysis of food supplements and quality control procedures.
