With the improvement of living standard, people are paying more and more attention on the freshness of meat products. T he Machine olfactory system was established to detect meat freshness simply and quickly. In this paper the principle of electronic nose system was introduced, six types of gas sensors were selected according to the composition of smell of corrupted meat, and hardware system of a machine olfactory was built by sensor array and data acquisition card. In addition, LabVIEW and MATLAB were used to finish data acquisition, data analysis and waveform display. In order to find the relationship between corrupted meat odor and the freshness, a machine olfactory system experiment device was made to do identification experiments of meat sample that stored 1-5 days. The results of experiment showed that gas concentration of detected pork samples was related to the storage time. So, it is feasible to identify meat freshness with machine olfactory system experiment device. © 2011 Springer-Verlag.
