Abstract
Thailand is the world's largest exporter of tropical orchid flowers. However, orchid flowers are fragile and sensitive to ethylene that has a major role in the senescence of most orchid flowers. Ethylene-induced symptoms include flower discoloration, premature wilting and flower fall. In addition, increasing ethylene gas concentration inside the flower packages during storage can cause premature senescence. This research was thus aimed to extend storage life of orchid flowers by using active packaging based on porous clay coated paper. The porous clay has high surface area with uniform and specific pore sizes and could be used as an ethylene scavenger. The developed active paper was used to keep orchid flowers, in comparison with those kept in regular packaging (control samples). Changes in orchid qualities were monitored throughout the storage period at 12ฐC and 85% until the flowers perished. The results showed that the active packaging could adsorb ethylene inside flower packages and thus prolong the storage life of orchid flowers.
