Abstract
The present invention provides improved packaging for harvested plant tissues, such as agricultural products. In some embodiments harvested plant tissues are placed in a package that contains either at least one hole, or a gas-permeable patch. The hole or patch is in turn covered by an adjustable aperture. The present invention improves available packaging methods by providing an additional level of control over the gas composition inside the package. Some embodiments of the present invention also mitigate damage to harvested plant tissues by contacting the plant tissues with ozone during transportation and storage. In some embodiments, harvested plant tissues are treated with ozone before packaging. The present invention also reduces costs by enabling the same package or kind of package to be used for different contents that have different atmospheric requirements for optimal protection from excessive ripening and spoilage.
