Abstract

The oak and pine charcoal were used to develop the inner packaging material for maintaining the freshness of vegetables and fruits, and to investigate the possibility in the application for inner packaging. The effects of the charcoal type, species, particle size, and grammage on the adsorption efficiency of ethylene gas were studied. White charcoal has superior ethylene gas adsorption performance to those of black charcoal. Pine charcoal was superior to oak charcoal in the ethylene gas adsorption. Higher gas adsorption was obtained by the higher grammage sheet. The difference in the adsorption efficiency was not significant between ONP and KOCC.
