Mozzarella di Bufala Campana (MBC) is a PDO cheese produced from whole buffalo milk in specific regions of southern Italy. Due to the high price and the limited amount of buffalo milk, MBC is potentially subject to mislabelling, substitution or fraud. Italian researchers have used elemental and isotopic profiles of authentic samples of buffalo milk and the corresponding MBC samples collected in the reference area in winter and summer in an initial exploratory study. A model was developed to classify product categories for this cheese by merging MBC-PDO samples with non-PDO samples of buffalo mozzarella produced both inside and outside the reference area. Despite differences caused during processing, along with differences in the season and production area, the model was effective in distinguishing PDO and non-PDO mozzarella, particularly when non-PDO cheeses were made outside the MBC reference area.
