The Potential of Online Analysis Systems for the Chemotyping of the Egg Matrix

Abstract: The previous chapter focused on illustrating the potential of the latest analytical equipment to discover markers or groups of markers that are characteristic of LE spoilage. Depending on the resolving power of this chemotyping equipment, these markers would be either in the form of single molecules (in the case of high or low resolution spectrometers such as NMR or MS often coupled with chromatography), or in the form of groups of these same molecules, all of which are then identified unambiguously (NMR-HR and MS-HR, often coupled with chromatography), or in the form of a chemical signature reflecting the contribution of large chemical groups present in the sample (FTIR, NIRS, Raman).
