And the flavor compounds in two different milk were analyzed with SPME-GCMS. At present, the milking mode includes automatic milking and manual milking in cat- tle farm. Milk samples, collected from six healthy early/mid-lactation Holstein cows, were analyzed by static headspace (SH) and solid phase microextraction (SPME) combined with gas-chromatogra- phy and mass spectrometry (GCMS) in this paper. The result showed that the aroma compounds in milk (automatic milking) were more than that of milk (manual milking), but the off-flavor com- pounds in milk (automatic milking) were less than that of milk (manual milking).
