  • Patent number: 5711980
    Abstract: A method for extending the shelf life of harvested produce against decay and premature ripening includes initial cooling of the produce, and thereafter maintaining the produce at the reduced temperature and at high humidity during processing and storage and packaging to final shipment for consumption. Cooled water with preservative chemicals rinse the produce at initial processing to suppress the ripening process significantly. Subsequent temporary storage between processes and processing steps occur substantially at the reduced temperature and high humidity to maintain the produce in a state of reduced ripening activity. The harvested produce is cut up and sized for volume collection and temporary storage as infeed to combining and packaging processes as required. Prescribed amounts of selected produce are individually packaged and crated for shipment in cooled and humid cargo carriers to remote locations where shelf life against decay and premature ripening is significantly extended.
