Ethylene decomposition/excretion test
We have conducted experiments to confirm that the ethylene decomposition pad developed has ethylene decomposition and excretion activity. The verification tests wereconducted as follows: 2 liters of a standard ethylene gas of 10 to 300 ppm was sealed in a sample bag, and the change in the ethylene concentration in the bag with time was measured using a semiconductor gas sensor detector gas chromatograph, using SGHA-P2 GL. As a result of the analysis, it was revealed that ethylene was decomposed by about 80% ethylene, about 130 μg in about 3 hours (Fig 1 and 2).
Verification experiment using fruits and vegetables
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.
Papaya demonstration test
This document has demonstrated the ability to decompose a high concentration of ethylene in a short time. Investigation of the gas concentration in the sample bag after decomposition of ethylene has confirmed this pad not only decomposed ethylene gas, but also excreted as carbon dioxide in water Verification experiment was carried out on tomatoes, mini tomatoes, spinach… and also showed that this material has a fresh preservation effect.
