介绍了牛肉新鲜度检测机理 ,提出采用气敏传感器阵列采集牛肉气体 (味 )信息 ,利用概率神经网络作为模式识别处理方法用于检测牛肉新鲜度。通过对不同时间的牛肉样本数据测试与分析表明 ,该研究方法可识别牛肉新鲜度。
The detection mechanism of beef freshness was introduced. Gas sensor array was used to collect the information of beef gas, and the probabilistic neural network was used as a pattern recognition method to detect the freshness of beef. Testing and analyzing the data of beef samples at different times showed that the research method can identify the freshness of beef.
