Composti volatili in latti pugliesi da allevamenti con diverso regime alimentare

Milk from farms located in less-competitive areas of Europe can be appraised by characterizing the specific features deriving from the territory. In the present study milks were compared from Apulian farms, situated in the same area (Murgia highlands) but with different feeding techniques. Through the volatile compounds profile, assessed by the SPME technique and GC-MS analysis, it was possible to discriminate the milk produced by grazing cattle from that produced in intensive dairy farms. In particular, the results confirmed that terpenoids are a powerful chemical index to identify milk which comes from grazing cattle and that these could also indicate the origin from a specific micro-area.
