Various metal catalysts on activated carbon will effectively remove ethylene
from air passing over the bed of carbon. Commercial units, known as
swingtherm ethylene converters, are based on such a system. However, they
require heat and movement of gases and so are not applicable to packaged
produce. Activated charcoal impregnated with a palladium catalyst placed in
paper sachets effectively removed ethylene in an experiment on maintaining
quality of lightly processed kiwifruit, banana, broccoli and spinach (Abe and
Watada, 1991).
