  • Patent number: 7629012
    Abstract: A method for processing a food product involves transporting the food product through a plurality of stations including a loading station, a pasteurization station, and a closing station. The surface of the food product is pasteurized by convectively transferring heat from the pasteurizing medium to the surface of the food product at a rate such that the surface heat transfer coefficient becomes sufficiently higher than the food product conductance coefficient that the surface temperature of the food product is substantially instantaneously elevated above temperatures which are instantly lethal to microbes which may be present. Preferably, steam is condensed on the food product surface in dropwise condensation, and the onset of film condensation is retarded by removing condensate film from such surface.

    Abstract: A disinfestation treatment chamber for treating fruit, flower and vegetable commodities subject to infestation by quarantine pests. The commodities are disinfested so as to meet quarantine restrictions without adversely affecting the quality of the commodity. The commodity is heated inside of the chamber in hot air having a relative humidity of 30-85% until the temperature of the commodity exceeds the thermal death point temperature of the target pest but is not so high as to adversely affect the quality of the commodity. The temperature of the commodity is held at this temperature until the pest is killed. The commodity is loaded into the treatment chamber in bins onto a low friction conveyor track system which transports the bins from one end of the chamber to the other. The commodities are treated while they are inside of the treatment chamber. After treatment of the commodities, the bins are unloaded using the low friction conveyor track system out of the opposite end of the treatment chamber.

    Abstract: The invention provides two-component shelf-stable packaged food products, especially packaged sauce products. The products comprise a container, a first food component filling a first region of the container, and a second food component filling a second region of the container, wherein the second food component either directly contacts the first food component or is separated therefrom by an edible interfacial layer. The second food component can be decanted off the first food component, and the second and first food components are adapted for use in combination in sequential food preparation steps. Preferably, the first food component is a thick sauce concentrate and the second food component is a vegetable oil containing chopped vegetable pieces. The vegetable oil and vegetable pieces are decanted and fried, prior to addition of the sauce concentrate, thereby achieving improved organoleptic properties.

  • Patent number: 6391357
    Abstract: A method for packaging, cooling, and storing fresh produce is disclosed. The produce is placed in a plastic bag having apertures that control ventilation so as to admit a fumigant gas but prevent significant moisture loss. Multiple units of the bagged produce are, in turn, placed in a corrugated shipping container. Using the bag design shown it has been found that humidity of the cold storage environment may be safely reduced to about 65-75% without significant deterioration of the contained produce. This is in contrast with the usual 90% RH environment needed to prevent moisture loss. The reduced humidity environment effects a very significant improvement in shipping container compression strength. Storage at 70% RH, in contrast to storage at 90% RH, results in an almost 50% improvement in compression strength. The result is less damage to the containers and their contents. Somewhat lighter weight shipping containers are also suitable, resulting in reduced costs.

  • Patent number: 6387430
    Abstract: Processing techniques for preserving and packaging foods with an extended shelf life that helps overcome the shortcomings of conventional processes. The invention includes four basic innovations—(1) performing the steam cooking and subsequent cooling steps in the same vessel, (2) evacuating the vessel before steam is introduced for cooking, (3) introducing steam into the vessel while the vessel is still under vacuum, and (4) vacuum cooling the cooked food. Accordingly, in one embodiment of the invention, the process includes the steps of placing a food product in a vessel, cooking the food product in the vessel with steam and then cooling the cooked food product in the same vessel without exposing the food product to cooling water or other potential sources of external contamination.

  • Patent number: 6374575
    Abstract: A method and an apparatus therefor for stabilizing products in containers in a continuous container flow by stationary, sequential sections by means of overflowing liquid, whereby the sections are graduated with respect to one another in terms of their liquid temperature, and for purposes of efficient liquid recycling are organized in pairs, so that the liquid is transported by overflow among sections, and to set the desired temperature of the overflowing liquid, liquid is added to the liquid being transported, characterized by the fact that the excess liquid in the at least one zone overflows in a cascade fashion from zone to zone of increasing overflow temperature and into liquid reservoirs.

  • Publication number: 20020004090
    Abstract: The invention concerns a method for packaging beverages in containers, particularly non-modified polyethylene terephthalate containers, which consists in pasteurizing (3) the beverage, cooling the pasteurized beverage to a temperature lower than that at which the containers are deformed, sterilizing the containers and container tops, filling the sterilized containers with a cooled pasteurized beverage, corking the filled sterilised containers, and further pasteurizing (10) the filled and corked containers to a temperature lower than at which the containers are deformed by the action of an excessive amount of heat. The invention is applicable to packaging of beverages.

  • Publication number: 20010053402
    Abstract: A method for preparing a sterilized liquid cooking sauce comprises the steps of: (a) mixing ingredients for liquid cooking sauces to form a liquid cooking sauce; (b) transferring the resulting sauce to a tubular sterilization means; (c) heating the sauce in the tubular sterilization means to thus sterilize the sauce; (d) establishing a back pressure within the sterilization means; and (e) packaging the sterilized sauce in containers; wherein the steps (c) to (e) are carried out while maintaining asceptic conditions and the pressure difference between the inlet and the outlet of the sterilization step is equal to 10 kg/cm2 or less. The method permits the preparation of a high quality sterilized liquid cooking sauce which shows small or no reduction of its viscosity and does not cause any color change.

  • Publication number: 20010046537
    Abstract: The present invention comprises a batch sterilization system, a controller for use in the batch sterilization system, and a method performed by the controller. The system, controller, and method are used to administer and provide on-line correction of a batch sterilization process performed on a batch of containers. The controller compiles an actual retort time-temperature profile during the batch sterilization process from the actual retort temperatures sensed by a sensor. While this is occurring, the controller controls a batch sterilizer so as to administer an initial portion of the batch sterilization process before a temperature deviation has begun according to a scheduled time-temperature profile. This temperature deviation is between the actual retort time-temperature profile and the scheduled processing time-temperature profile.

    Abstract: Packaging for microwavable convenience foods, such as tamales, and a related method for microwave steam heating or cooking of such foods. The food packaging includes an unvented, sealed, stretchable plastic bag enclosing a food product and a moisture pad which is placed on top of the food product. The pad serves to shield the food product from direct microwave radiation, and to provide a source of steam generated by absorption of the waves in the water of the pad.
