|
|
|
In this study, the geographical origin of beef was studied using an electronic nose based on mass spectrometer.Domestic beef was compared with the imported beef from New Zealand and Australia. Each sample was analyzed, anddiscriminant function analysis was used utilized for the discrimination of geographical origin. The R2 and F-value ofdiscriminant function analysis (DFA)1 were 0.4317 and 14.18, respectively when the samples were separated by geographicalorigin. The R2 and F-value of DFA1 were 0.8960 and 22.98, respectively when the samples were separated by part of beef.
