生物超微弱发光在猪肉新鲜度检测中的应用
Application of Ultra-weak Photon Emission in the Detection of Pork Freshness
摘要
Abstract
To find the best testing condition and to detect the freshness of pork,single photon counting system was used to test the changing intensity of spontaneous radiation and delay luminescence of pork in different condition.Average val-ue of noise was 76.3 counts/s during four continuous days,and the average deviation was 1.1 counts/s;Signal of fat meat was stronger than others,and there were some increasing progresses in intensity with the increase of storage time;Signal of loin fat meat was the strongest in delay luminous testing with fitting coefficient about 0.996,in addition,the characteristic time (t)of delay luminescence would be lower as the extension of the testing time,which revealed that the freshness was declining.The results revealed that this system has the characteristics of less amunt of samples and fast testing speed,which could be used in direct testing of fresh food in freshness.关键词
