ETHYLENE PRODUCTION OF ORGANIC AND NONORGANIC MATURE MUSHROOMS MEASURED BY LPAS

We have examined the potential of laser photoacoustic spectroscopy (LPAS) as a sensitive method for trace gas detection by assessing the champignon mushrooms quality, focusing the attention on quantitative determination of ethylene released by organic and nonorganic mature mushrooms. With the advantages of LPAS, it is observed that quantitative changes in production of ethylene occur in the respiration of nonorganic mature champion mushrooms compared with organic ones.
