Figure Lengend Snippet: Biplot OPLS-DA of Stilfser type without PDO (BATO, blue), Bergkäse without PDO (BK, green), and Tiroler Bergkäse PDO (BKGU, red). The samples show a separation according to the analyzed variables. Numbers (1−30) indicate the variables: 1 = 2,3-Butanediol, 2 = L. lactis subsp. lactis , 3 = L. lactis subsp. cremoris, 4 = S. thermophilus , 5 = 3-Methyl-1-Butanol, 6 = Ethanol, 7 = Isobutyric Acid, 8 = Isovaleric Acid, 9 = Acetic Acid, 10 = L. helveticus , 11 = Biacetyl, 12 = Benzaldehyde, 13 = 2-Heptanol, 14 = Acetoin, 15 = 1-Hexanol, 16 = Valeric Acid, 17 = Dimethyl Disulfide, 18 = Butyric Acid, 19 = Hexanal, 20 = Sum of FAA, 21 = L. delbrueckii , 22 = 2-Pentanone, 23 = 3-Methyl-Butanal, 24 = Hexanoic Acid, 25 = 2-Heptanone, 26 = 2-Nonanone, 27 = Propanoic Acid, 28 = L. mesenteroides , 29 = Octanoic Acid, 30 = L. casei group.
