Effect of the pig rearing system on the final volatile profile of Iberian dry-cured ham as detected by PTR-ToF-MS

The role of direct high-resolution mass spectrometry in foodomics

“…Analysis of VOCs by PRT-TOF MS permitted the discrimination among different olive varieties and stage of ripeness [47], as well as the monitoring of VOC release during post-harvest ripening of different apple cultivars [48]. Classification of dry cured hams produced following the indications of different protected designations of origin (PDOs) [49] and different diet of the pigs [50] was also achieved with PTR-TOF MS. Profiling hundreds of peaks from volatile compounds to study the evolution of volatile compounds during storage of dried porcini was also possible by PTR-TOF MS [51]. Owing to the importance of coffee volatiles in flavor attributes of coffee the suitability of PTR-TOF MS has been demonstrated in several works.…”

Direct Analysis Mass Spectrometry

“…The influence of pig diet on the VOC profile of dry-cured Iberian ham was examined with differences found in aldehydes, ketones, and sulfur-containing compounds [87].…”

Advanced Mass Spectrometry

“…The quadrupole is operated as an ion guide in MS mode and as mass selection device in MS/MS mode. A reflectron TOF analyzer is placed orthogonally to the quadrupole and serves as a mass resolving device for both MS and MS/MS modes [48][49][50][51][52][53][54][55]. A collision cell is located between the quadrupole and the TOF analyzer to induce fragmentation in MS/MS experiments [56][57][58][59][60][61].…”

“…This opens new horizons for research and allows for new applications in fields where the rapid and sensitive monitoring and quantification of VOCs are crucial in food sciences [54]. Very briefly, PTR-MS is based on the reaction of protonated water with VOC molecules with a proton affinity higher than that of water and the successive detection by a mass spectrometer [55].…”
