    Abstract: A method for storing respiring produce, particularly bananas, during ripening is disclosed. The method allows bananas to remain in the ripened condition for an extended period of time while, at the same time, having improved sweetness and taste characteristics. In addition, the method does not require separate handling and repackaging of the bananas between the starting of the ripening process and storage/shipment of the bananas. In this method, ripening is initiated by inserting additional gas into the banana package, such that the gas medium comprises from about 2.0% to about 5.0% oxygen, from about 5.0% to about 15.0% carbon dioxide, from about 0.8% to about 1.5% ethylene, the remainder of the gas medium being predominantly nitrogen, for a period of from about 0.5 to about 5 seconds. The composition of the gas medium in the package is then adjusted such that the gas medium has a ratio of oxygen to carbon dioxide which meets the following conditions: (20.94?B)/C=from about 1.8 to about 3.

    Abstract: The preservation of meat products is accomplished utilizing a combination of smoke, ozone and freezing preservation techniques. Particularly, fish products are sized into portions that are first treated with smoke, followed by treatment with ozone and then optionally frozen. The preservation system extends the shelf life of the fish products and permits the fish to maintain its freshness and freedom from bacterial decomposition for a longer period of time following catch. The preservation process further maintains the characteristics of day caught fish, such as taste, texture and color, making the refreshed fish products produced by the present system more appealing to consumers.

    Abstract: The invention allows cool rooms or sea containers designed for frozen goods to handle produce requiring more precisely controlled temperatures and conditions, e.g., vegetables and fruits requiring temperatures in the chilling range and often also needing control or modification of the atmosphere. Each load of produce (100) (e.g. of pallet size) is held in the sea container or cool room but is sealed from the air of the refrigerated environment by, for example, a plastics bag (56). The atmosphere within the bag is then circulated by a fan (12) (or by convection currents from a heating element) so as to pass through the load and around it via ducts (30) provided adjacent the bag (56). Heat exchange (50) between the circulating gas and the refrigerated environment, via the plastics film, serves to cool the load. However, if cooling is excessive a heating element can be used to raise the temperature of the circulating atmosphere. Gas composition of the atmosphere can be controlled by scrubbing, flushing, etc.

  • Patent number: 5460841
    Abstract: A method for uniformly controlling the ripening of bananas and other perishable products from harvest to delivery, wherein a combination shipping and ripening container having an internal volume capable of receiving and maintaining a controlled atmosphere is provided. Freshly harvested, unripened perishable products are loaded into the container and cooled to a holding temperature in a range of from about 57.degree. to about 70.degree. F. Once the products are stabilized at the desired holding temperature, a controlled atmosphere including ethylene is preferably substantially immediately provided to the internal volume to uniformly initiate ripening of all of the loaded products. Once ripening has been initiated, the ethylene is reduced within the internal volume by displacement with a low oxygen controlled atmosphere, which is maintained within the container during storage, transportation, and delivery procedures.

  • Patent number: 5250317
    Abstract: Black tea leaves are oxidized to provide treated leaves from which aqueous tea extracts which have minimal turbidity, particularly when cooled, may be obtained. The oxidation reaction is performed on black tea leaves which contain moisture only in an amount such that the oxidation reaction occurs at localized sites on and within the tea leaf structure.

  • Patent number: 4919955
    Abstract: A method and apparatus for packaging perishable products is disclosed, said method and apparatus enabling the alteration of the gaseous environment surrounding a given product. The packaging system can be readily prepared for immediate transport and aging, retail display and consumer freezing. The present system comprises a relatively rigid tray which is sealed with a flexible gas impermeable cover, said tray being provided with a resealable septum valve. The tray is also preferably provided with a plurality of protrusions or mounds so as to facilitate gas flow and contact with a given perishable product. The atmosphere in the packaging system may be modified to inhibit bacterial decay of the product and/or to enhance its appearance. Likewise, the package may be prepared for freezing by drawing a substantial vacuum within the packaging system.

  • Patent number: 4779524
    Abstract: In a method and apparatus for controlling the ripening of fresh fruit, a stack of fruit boxes is spiral wound with a transparent synthetic resin strip around the four vertically oriented faces of the box stack. The boxes within the stack have openings on their upper and lower faces which register with corresponding openings in vertically adjacent boxes to permit a vertical movement of an air-ethylene mixture through the stack. A plastic cap or lid is disposed on top of the stack of boxes and is provided with a blower for drawing air vertically through the stack from the bottom thereof. An air-conditioning unit and an ethylene containing bottle may be disposed in a unit on which a pallet supporting the stack of boxes rests. Effluent air or a mixture of air and ethylene is fed back to the air-conditioning unit via a conduit on the outside of the wrapped stack of boxes.

  • Patent number: 4400291
    Abstract: An ethylene gas generating liquid composition for catalytic conversion to ethylene. Ethanol is the primary ingredient of the liquid composition but there is also present 1.0% to 15% methanol, 0.1% to 10% of an ester such as amyl acetate and 0.1% to 15% of an aliphatic alcohol such as isopropanol. This liquid composition has been found to maintain a high conversion efficiency for the catalyst and minimizes the production of by-products.

  • Patent number: 4224347
    Abstract: To extend their shelf life, certain vegetables are placed in enclosures that are at least as permeable to carbon dioxide, carbon monoxide and oxygen as low density polyethylene that is not more than two mils thick, the atmosphere within the packages is modified to comprise at least about 25% oxygen by volume, at least about 3% carbon monoxide by volume, and the balance substantially all molecular nitrogen, and the packages are then sealed. The permeability should be sufficient to prevent the carbon dioxide concentration from rising much above 20% by volume, and to prevent the oxygen concentration from falling much below about 2% by volume.
