Abstract :A mothod on monitoring for degree of beef fresh2 ness which using gas sensitive sensor array is introduced. With this method ,beef freshness can be monitored by use of pattern recognition with probabilistic neural network from gas information released by beef . The results of this investigation have made clear that beef freshness can be monitored based
on analysis of sample data collected at different degree of beef freshness.
Key words :gas sensitive sensors array ; PNN ;pattern recog2 nition ;degree of beef freshness
