The aim of this study is to combine advanced GC-MS and metabolite identification in a robust and repeatable technology platform to characterize the metabolome of buffalo milk and mozzarella cheese.The study utilized eleven dairies located in a protected designation of origin (PDO) region and nine dairies located in non-PDO region in Italy.Samples of raw milk (100 mL) and mozzarella cheese (100 g) were obtained from each dairy.A total of korpskaft 185 metabolites were consistently detected in both milk and mozzarella cheese.The PLS-DA score plots clearly differentiated PDO and non-PDO milk and mozzarella samples.

For milk samples, it was possible to divide metabolites into two classes according to region: those with lower concentrations in PDO click here samples (galactopyranoside, hydroxybuthyric acid, allose, citric acid) and those with lower concentrations in non-PDO samples (talopyranose, pantothenic acid, mannobiose, etc.,).The same was observed for mozzarella samples with the proportion of some metabolites (talopyranose, 2, 3-dihydroxypropyl icosanoate, etc.,) higher in PDO samples while others (tagatose, lactic acid dimer, ribitol, etc.,) higher in non-PDO samples.

The findings establish the utility of GC-MS together with mass spectral libraries as a powerful technology platform to determine the authenticity, and create market protection, for “Mozzarella di Bufala Campana.”.
