The shelf life of two Chinese traditional cheese was measured using classical analysis and a commercial electronic nose.To determine quality decay through changes of pH,acidity and WHC(water hold capacity);The quality of cheese aroma was evaluated by inspecting the headspace fingerprint of the same set of samples using the electronic nose.The results of this study showed that electronic nose was able to identify the above cheese by LDA method.The shelf life ranges obtained by the electronic nose and traditional analytical techniques are substantially similar.
