“…The variation can be attributed to the fact that the cheese samples used in this study were obtained from different producers and different geographical locations, as well as being produced at different intervals. The protein profiles and their intensities in the cheeses are greatly influenced by the different production protocols of each production unit [ 2 , 9 ]. For multiple comparisons between the groups, we submitted p -values obtained from the ANOVA to Tukey’s post hoc analysis in GraphPad Prism 6.0 software.…”

“…The variation in climatic conditions, feed type, grassland, and phenological stages influences the protein profiles of the milk, which in turn influences the protein composition of the cheeses. These results show that the geographical origin (and indirectly the environment and diet) plays a key role in the peptide profile of cheeses [ 2 ].…”

“…Food authentication procedures are gaining much importance in the international food market because of increasing consumer awareness regarding food quality and safety. Market globalization and industrialization of food products forced the industry to become very competitive and financially profitable by creating more opportunities in adulteration/false labeling [ 1 , 2 ]. The growing demand for high-quality foods, the desire for new delicate products or foods having specific organoleptic traits, and the consumer’s ability to pay a high price provoke more vulnerability in counterfeiting [ 3 ].…”

“…The cheese producers must compulsorily provide the species origin of milk as few consumers evade cow’s milk for allergic/intolerance disorders and ethical/religious reasons [ 5 , 9 ]. Because of these legal aspects and consumerism and reliability in the dairy industry, authentication becomes mandatory to define the uniqueness against frauds or commercial disputes [ 2 , 10 ].…”

Geographical origin and authenticity are the two crucial factors that propel overall cheese perception in terms of quality and price; therefore, they are of great importance to consumers and commercial cheese producers. Herein, we demonstrate a rapid, accurate method for discrimination of domestic and import mozzarella cheeses in the Republic of Korea by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). The protein profiles’ data aided by multivariate statistical analysis successfully differentiated farmstead and import mozzarella cheeses according to their geographical location of origin. A similar investigation within domestic samples (farmsteads/companies) also showed clear discrimination regarding the producer. Using the biomarker discovery tool, we identified seven distinct proteins, of which two (m/z 7407.8 and 11,416.6) were specific in farmstead cheeses, acting as potential markers to ensure authentication and traceability. The outcome of this study can be a good resource in building a database for Korean domestic cheeses. This study also emphasizes the combined utility of MALDI-TOF MS and multivariate analysis in preventing fraudulent practices, thereby ensuring market protection for Korean farmstead cheeses.

“…PGI, on the other hand, is a label associated with agricultural products or foodstuffs, in which a given step (s) of production, processing or preparation is associated to a specific geographical area, while the raw material used in production can come from another region. Finally, TSG is attributed to agricultural products and foodstuffs that are produced using traditional raw material or production methods, but the final product labelling of origin is not restricted to a given geographical area (Barron, Aldai, Virto, & de Renobales, 2017).…”

Background: Food fraud has become an increasingly worldwide problem mainly driven by rapid innovation in the food sector and constantly changing consumer's choices. This led to an increased necessity to improve/establish reliable authentication processes, resulting in the replacement of protein-based techniques for dairy products authentication by higher sensitive and reproducible DNA-based methods. Most used molecular methods for dairy products authentication include PCR, Real-time PCR, multiplex PCR, and PCR-RFLP. Despite the several molecular methods available for species/breeds differentiation in dairy products, there is a need for the development of more efficient and reliable molecular tools. Scope and approach: In this review, traditional and more recent DNA-based methods for dairy products authentication are discussed and analysed. Moreover, the increasingly important role of bioinformatic tools for analysis of large amount of data and for the development of DNA markers is also discussed. Key findings and conclusions: DNA quality is one of the major factors affecting molecular-based dairy products authentication, which can be influenced by the manufacturing process, extraction method employed, chemical composition of the food matrix, among others. PCR-based methods continue to be the most important and successfully used for dairy products authentication. The DNA markers chosen for species/breed detection are an important factor for PCR success. Although there are several molecular methods for the detection of adulterant species, there is still an unmet demand for methods to detect adulterant breeds. Available public databases and bioinformatics revolutionized the analysis of large amount of data and will be pivotal for the development of effective DNA markers.
