Ethylene gas adsorption capacity and preserving effect of fruit freshness of Charcoal-fiberboard by wet forming process

This research was carried out for packing materials and building materials to examine thylene gas adsorption and effect of keeping fruit fresh of wet formed charcoal-fiber mposite made from defibrated fiber of Pinus densiflora Sieb. et Zucc. and white charcoal from uercus variabilis Bl.(wood fiber: charcoal=8:2, 6:4, 4:6, 2:8), with/without phenol formaldehyde resin(PF, Non volatile content:52%, resin content 1,3,5%). The results are summarized as follows: 1. The higher the charcoal content, the more the ethylene gas adsorption. At the same mixing ratio of fiber to charcoal, #100-200 of charcoal particle size gave the better reslts than # 60-100. 2. Adding PF into the charcoal fiber composite decreased the capacity of ethylene gas adsorption but there was no significant difference until 5% adding amount of PF. 3. For keeping fruit fresh for a long time, Charcoal fiber composite was 66% longer than control. The higher the white charcoal content, the longer fresh time.
