A method of storing potatoes includes providing a plurality of dormant potatoes, wherein the potatoes have been cured after harvesting; in a first treatment step, treating the potatoes with 1-methylcyclopropene by exposing the potatoes, which are at a first treatment temperature within the range of from 10 to 30° C., to 1-methylcyclopropene; storing the potatoes at a second storage temperature within the range of from 4 to 15° C.; and in a subsequent second treatment step during the storing step, treating the potatoes with ethylene by exposing the potatoes, which are at the second storage temperature, to ethylene.

An inclusion complex of an amorphous -cyclodextrin, or derivative thereof, with encapsulated ethylene is provided by exposure of the dry solid amorphous -cyclodextrin to ethylene gas under pressure. The inclusion complex will have applications in a number of fields including fruit ripening.

A pass-through system and method for treating and/or pre-cooling perishable products uses a conveyor system with a treatment chamber that is configured to be contained (or closed) to provide a sealed environment and enhanced with forced air flow to recirculate air and/or functional substances including, e.g., sanitizers, as well as ripening management and conditioning agents, across the surface of perishable products. The enhanced forced air is an integral part of the system for efficient treatment and can also be cooled to accomplish rapid cooling.
