Research on Ultra-weak Bioluminescence Detection and Features for Freshness of Corn

By Hu Hongsheng, Niu Qunfeng and Cui Boyuan

Abstract

Abstract. Detection of ultra-weak bioluminescence for freshness of corn is not only a problem of corn safe storage but also related to corn quality. The paper built a Virtual Instrument platform based on LabVIEW and PXI4220 modularized hardware of NI. Then, a testing and analysis system for corn ultra-weak bioluminescence features was designed. Different freshness corns were tested and analyzed about the relation of freshness and ultra-weak bioluminescence features. The experimental results shows that the ultra-weak bioluminescence voltage peak values of different freshness corns all maximize about 1 hour, and voltage peak values between different freshness corns have no evident relationship. However, the ultra-weak bioluminescence voltage energy sum of different freshness corns increase progressively with the freshness degree. So, detection of voltage energy sum of different freshness corns can reflect wheat freshness effectively. Comparing with traditional method, the freshness detection method based on wheat ultra-weak bioluminescence features can realize precise, rapid and nondestructive examination
