Aroma compounds of some Hyblean pasture species

The presence of dairy cattle in pastures of very great diversity in plant species presents an interesting problem for study. The objective of this study was, in combination with results of Carpino et al. (2003), to contribute to the characterization of Hyblean native species by utilizing GC–O and GC–MS analysis to identify compounds that may be used as markers to verify Ragusano cheeses as Protected Denomination of Origin (PDO) products.
