Abstract:
A gas-selection device for a sealed storage container with modified or controlled atmosphere, remarkable in that it includes a hollow body and at least one first orifice, a second orifice and a first membrane, said first and second orifices connecting the inside of said body to the outside, said first membrane being disposed inside said body between said first and second orifices so that the gases flowing from the first orifice to the second orifice, or vice versa, necessarily and solely pass through said first membrane, and in that the device is arranged so as to be secured sealingly to one of the walls of the container, so as to allow a flow of gas from its second orifice through the wall, or vice versa.
Abstract:
A gas supply device supplies an internal space of a container with nitrogen-enriched air to reduce an oxygen concentration of the internal space. If the oxygen concentration of the internal space gradually falls to reach a reference concentration C2, the gas supply device stops. If outside air enters the internal space at a gap between the container and a container refrigeration apparatus, the oxygen concentration of the internal space rises after the stop of the gas supply device. If the oxygen concentration of the internal space rises to reach an upper limit concentration C3, an internal fan controller switches a rotational speed of an internal fan from “HIGH” to “LOW.” The gas supply device is activated. As a result, the amount of the outside air entering the internal space can be reduced to reliably drop the oxygen concentration of the internal space.
Abstract:
An optimized package for holding a perishable produce that balances between optimum aerobic and anaerobic conditions. The package has a body, formed of a package film having a first size and shape, formed with laser micro perforations formed according to a relationship between a shelf life of said first contents in said package for different oxygen transfer rates expressed as volume of oxygen per time period per package per atmosphere. This is set to optimize between anaerobic conditions and aerobic conditions. There are a number and size of micro perforations, to obtain an optimum oxygen transfer rate. The micro perforations can be formed in a location of the package which retains airflow through the micro perforations when multiple of said packages are stacked. There can also be a humidity reduction device, which can be a valve, or a vapor transmitting film, or a hydroscopic salt on the exterior of the film.

Provided are methods of preserving and/or storing Synsepalum dulcificum berry, which may involve separating a pulp of the berry into two or more parts; and freeze drying the berry with the separated pulp.
Abstract:
Systems and methods for detecting presence of a thing, the thing treated with a descenter, one method including in an area in which it is possible that a thing treated with a descenter is present, using a detector to detect a descenter level in the area, producing a detected descenter level, comparing the detected descenter level to a normal descenter level for the area, determining that the detected descenter level is different from the normal descenter level, said determining indicating the possible presence of a thing treated with a descenter; and using a trained service animal to facilitate such a method.
Abstract:
A catering box with active climate control is configured to transport “delicate” foods, such as grilled cheese sandwiches, hot dogs, and hamburgers, without inducing substantial sogginess in the bread of those food items. The catering box includes a heat mass configured to retain heat generated by a hot plate and to then radiate that heat, during transport, after the hot plate has been disconnected from a power source. In addition, the catering box includes an exhaust fan that actively controls internal specific humidity levels in order to prevent moisture from settling within the bread of stored food items. A microcontroller within the catering box monitors temperature and absolute humidity levels, computes the current specific humidity level, and then selectively engages or disengages the exhaust fan in response. With his approach, the catering box may limit the degree to which humidity settles within the bread of delicate food items stored within.
Abstract:
A regenerative carbon dioxide removal system (38) is provided onboard the container (10) through which air from within the cargo box (12) may be circulated for removing at least a portion of the carbon dioxide present in the air. The regenerative carbon dioxide removal system (38) includes a scrubber module (40) containing a carbon dioxide absorbent material (42), and an actuator (50) for moving the scrubber module (40) to pass the carbon dioxide absorbent material (42) alternately between a first flow of air (32) to be cleaned drawn by the evaporator fan (30) from within the cargo box (12), and a second flow of air (44) drawn from an environment outside the cargo box for regenerating the carbon dioxide adsorbent material (42) by removing collected carbon dioxide from the carbon dioxide adsorbent material (42).

Abstract:
Grapes while attached to the stems where they formed are cooled with the removal of excess moisture and are enclosed within an enclosure containing a gaseous atmosphere (e.g., air) bounded by a semi-permeable film having an oxygen transmission rate of approximately 100 to 400 cm3-mil/m2/24 hr., and preferably approximately 260 to 325 cm3-mil/m2/24 hr. The enclosure is sealed and the concentration of carbon dioxide present therein is adjusted to an initial concentration of approximately 3 to 19 percent by volume (preferably 13 to 18 percent by volume). The initial concentration of carbon dioxide within the specified semi-permeable enclosure has been found to well prolong the storage life of the grapes stored therein at a temperature of approximately 31 to 35° F. with the advantageous promotion of continued grape respiration at a low level during storage. The grape quality for the intended end use (e.g., human consumption as a table grape) is effectively extended. Prolonged storage for 30 or 60 days or more in the storage zone is made possible. Accordingly, the time for the otherwise perishable grapes to serve their intended use is effectively extended in a straightforward and economical manner while using otherwise standard cold storage conditions.
Abstract:
The preservation or extension of the life of oxygen perishable products such as fresh or cooked meats; fresh vegetables and fruits; dried vegetables, fruits and meats; packaged pharmaceuticals or biologicals; open and enclosed marketing display cases of meats, fruits and vegetables; and packaging, warehousing and transportation of meats, fruits, and vegetables is obtained by subjecting such products to an atmosphere obtained from gas permeable packets of an oxygen scavenging composition comprising a sodium carbonate mineral and one or more carboxylic acids. When the environment surrounding the oxygen perishable product is subjected to the packets of gaseous permeable oxygen scavenging compositions, oxygen is taken in by the scavenging composition and also the presence of carbon dioxide in the surrounding environment is enhanced thereby minimizing or eliminating the effect the oxygen on the oxygen perishable products.
