The drawback of derivatization reactions is that they are time-consuming, and intensive and tedious labor. 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.

The sensitivity of MS analyses can be greatly increased when a second round of fractionation is applied to the mixture of peptides using nano-flow LC before introduction to the MS. De novo sequencing of peptides using MS/MS provides an invaluable tool for identifying proteins on the basis of amino acid sequence homology searches from available databases. Currently, only five ray-finned fish species have complete (or nearly complete) genome sequences deposited in databases, including zebrafish, fugu, medaka, tetradon, and three-spined stickleback, which can be used for identification of proteins from proteomic approaches.
