Abstract
A method for packaging, cooling, and storing fresh produce is disclosed. The produce is placed in a plastic bag having apertures that control ventilation so as to admit a fumigant gas but prevent significant moisture loss. Multiple units of the bagged produce are, in turn, placed in a corrugated shipping container. Using the bag design shown it has been found that humidity of the cold storage environment may be safely reduced to about 65-75% without significant deterioration of the contained produce. This is in contrast with the usual 90% RH environment needed to prevent moisture loss. The reduced humidity environment effects a very significant improvement in shipping container compression strength. Storage at 70% RH, in contrast to storage at 90% RH, results in an almost 50% improvement in compression strength. The result is less damage to the containers and their contents. Somewhat lighter weight shipping containers are also suitable, resulting in reduced costs.
