Abstract:
A celery product is produced by the steps of optionally cutting the celery to a predetermined length, cooking the celery for a period of about 60-120 seconds in an aqueous medium at a pH of about 1.0 to 1.5 and a temperature of at least 190null F., transferring the cooked celery to an aqueous medium in a filling machine at an initial pH of about 2.4 to 2.6, transferring the celery from the filling machine to a sealable container filled with water at a temperature of about 190null F., sealing the container and allowing the water to cool to form a vacuum packed celery product having a pH of about 3.5 to 4.2. The celery product is shelf stable for long periods of time and retains the flavor and texture of fresh celery due to the short cooking time.
Abstract:
Packaging of bananas in containers having designed permeabilities to oxygen, carbon dioxide, and ethylene. The containers preferably include a gas-permeable membrane comprising (1) a microporous film, and (2) a polymeric coating on the microporous film. The containers enable storage and/or ripening of bananas under controlled conditions. Using the new containers, bananas can be ripened while they are being transported, or in conventional ripening rooms without opening the bags in which they have been transported. In addition, bananas can be preserved in a satisfactory ripened state for longer periods of time.
Abstract:
Methods for disinfesting insect pests such as the Mexican fruit fly in citrus fruit such as grapefruit with minimal adverse effect on fruit quality include placing and maintaining such fruit for a time period of about 15 to about 21 days at a temperature of about 14null to 18null C. and in a gaseous mixture that includes not more than about 0.05% oxygen by volume, a balance nitrogen or up to 20% carbon dioxide in combination with nitrogen.
Abstract:
A chiller for fresh fruit and other perishable food products is cooled with a thermoelectric device and includes a cool air recirculating system that minimizes air flow path lengths and provides uniform cool air distribution throughout a fruit container removably supported above the thermoelectric module. The cooling air flow duct system is formed in part by the bottom wall of the container, thereby enhancing direct cooling air flow contact in minimizing the lengths of the flow paths.
Abstract:
A tray for packaging sliced tomatoes is disclosed that maintains the tomatoes is fresh condition by controlling the atmosphere surrounding the tomatoes and reducing contact between tomatoes and their serum exudate. This is achieved by a tray configuration that holds the tomato above the exudate which is collected in a reservoir at the base of the tray. Means are provided to facilitate loading tomatoes into the tray and for removing the tomatoes from the tray.
Abstract:
A method of preserving produce by providing a plastic packaging material having a thickness of up to about 500 microns and a permeability to water vapor exceeding about 1.5 g mm m−2 per day at 38° C. and 85-90% relative humidity, whereby when the material is used to package produce, no condensation or minimal condensation appears on a surface of the material. Related methods and products produced thereby are also described and claimed.
Abstract:
This invention describes the transient incorporation of CO.sub.2 gas into fruits and vegetables so as to enhance their flavor. The fruits and vegetables are exposed to a strongly CO.sub.2 environment for a specified amount of time and within a specific temperature range. After this exposure the foodstuffs so exposed will have incorporated some of the CO.sub.2 to which they were exposed to and develop a more effervescent and/or tangy flavor through the uptake of the CO.sub.2 to form carbonic acid. This enhancement in flavor is a direct consequence of CO.sub.2 exposure.
Abstract:
A transportable and size-adjustable ripening apparatus for controlled ripening of produce includes a chamber defined by a ceiling, a floor, and walls connecting the ceiling and the floor. The chamber is configured to receive a row of boxed produce that defines an interstitial volume with one of the walls to create a low-pressure plenum. The ripening apparatus also includes an air flow control system for transferring air between a high pressure plenum and the low pressure plenum, and which controls the temperature of the transferred air. The plena are generally enclosed to inhibit airflow therebetween except for airflow through the air control system and through openings in the produce boxes. The air control system includes one system for controlling the flow of air through a refrigeration unit, and another system for circulating air without refrigeration. The invention is preferably constructed from an existing ISO (International Standards Organization) container. The container may be mounted on a chassis with wheels, to thereby be transportable.
Abstract:
The present invention relates to a method for long term storage of pickles in an environment free of brine or other liquid media. The method includes treating cucumbers in a brine solution at a temperature of about 195.degree. F. and then storing for about 24-72 hours at refrigeration temperatures to make pickles. The brine includes a preservative such as sodium benzoate. The brine is drained from the pickles. The pickles are packaged in a container free of brine or other liquid media at refrigeration temperatures.
Abstract:
A patch (10, 30, 40) or other device applied to a fruit or vegetable for releasing a gas, preferably ethylene, which accelerates maturation or which retards maturation, preferably carbon dioxide. The device attaches to a portion of the fruit or vegetable and releases the gas upon application or upon demand. Ripening or retardation is selective in a bunch of connected fruits such as bananas when applied to one finger, thereby providing selective ripening.
