Efficacy of active coated papers incorporating different adsorbents of either activated carbon or zeolite on ethylene adsorptions The suitable formula of active coating solution in the section 4.2 was selected from which provided the highest PIRG and spore germinations of mango anthracnose fungi. From the section 4.2, experimental results indicated that VCC 1.0 was the suitable active coating solution, due to its inhibitory effect and solubility. In this study, VCC 1.0 was used for preparing active coated papers incorporating different types and amounts of the ethylene adsorbent. Two different types of ethylene adsorbents including zeolite and activated carbon were individually added into the VCC 1.0 and homogeneously mixed to obtain various adsorbent concentrations (0.1,

Each active coated paper with an A4 size was subjected into the glass bottle (720 mL) and closed with a lug lid. Five mL of 100 ppm of the ethylene (or about 4.17 ppm) was fed into that glass bottle through a septum on the center of the aluminum lid. To check the leakage of the container, the glass bottle containing 4.17 ppm ethylene gas was investigated in a parallel test. Without the leakage of the container, experimental results are shown in Figure 4.17 and Table 4.5. All active coated papers could reduce the ethylene concentration existing in the surrounding air during storage times. The ethylene concentration surrounding the ordinary white paper without any coating or the uncoated paper (shortly called as UNC) continuously reduced during the storage time increased. Similarly, the paper coating with the VCC 1.0 could adsorb the ethylene into its surface, resulting in decreasing of the ethylene concentration throughout storage times as
