| Abstract: | Fiore Sardo (FS) is a traditional Italian raw ewe’s milk cheese carrying a Protected Designation of Origin (PDO). This study investigated the kinetic of FS cheese ripening by physicochemical parameters, microbial counting, and NMR metabolomics using aqueous extracts. Four Fiore Sardo cheeses, manufactured from milk with deliberately added autochthonous lactic acid bacteria (LAB) or commercial starters were studied during a period of 90 days of ripening. Major differences in the metabolic profiles were observed amongst the samples as a function of the adjunct culture utilized. 1H NMR metabolomics in combination with multivariate data analysis was able to classify cheese samples on the basis of their maturation age and the type of added cultures. These findings lay the metabolic basis for the authentication of Fiore Sardo cheese produced in compliance with PDO specifications which allow the use of only native LAB cultures. |
