• In order to investigate whether the fruit-derived ethylene gas was decomposed, the same amount of mini-tomatoes were enclosed in the sample bag and the control bag, and after 3 hours, 20 hours, 44 hours, 68 hours and 92 hours in the bag of ethylene gas concentration was measured. As a result, it was clarified that the ethylene concentration increases in the control bag, while the accumulation of the ethylene gas in the sample is suppressed to within 0.6 ppm.
