Publication number: 20040131739Abstract: A continuous method using gaseous carbon dioxide or a pressurized flow of liquefied carbon dioxide is described to reduce microbial and/or enzymatic activity in a liquid product. The carbon dioxide is combined with a pressurized flow of the liquid product, or the mixture is pressurized after the mixture is formed. The pressure and temperature in the flow regions are maintained at a level which is sufficient to keep the carbon dioxide in a continuous liquid state, but which does not freeze the liquid product. The pressurized mixture of the carbon dioxide and liquid product flows through a reaction zone for a sufficient time to reduce harmful microorganisms and/or inactivate enzymes and then enters one or more expansion stages wherein the pressure of the mixture flow is sufficiently decreased to vaporize the carbon dioxide for separation from the liquid product. If necessary, heat is applied in at least one of the expansion stages to prevent a freezing of the mixture.Type: ApplicationFiled: September 16, 2003Publication date: July 8, 2004Inventor: Murat O.

Publication number: 20040105927Abstract: 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.Type: ApplicationFiled: July 8, 2003Publication date: June 3, 2004Inventors: Vernon D.

Patent number: 6426103Abstract: The invention relates to a process for eliminating pathogenic organisms and other bacteria from raw food products, such as raw shellfish, whereby the molluscan shellfish is exposed to hydrostatic pressure of relatively high value, for example between 20,000 p.s.i. to 150,000 p.s.i. for 1-15 minutes. The process is conducted at minimal elevated temperatures, in the range of above ambient temperature to 150° F., leaving the raw shellfish substantially unaffected, in its desired raw state, such that the pathogenic organisms are destroyed, while sensory characteristics of the raw shellfish remain high. The same process can be used for shucking bivalve mollusks without any mechanical force, with the pressure ranging from 10,000 p.s.i. to 100,000 p.s.i. Taste of raw seafood is enhanced by adding flavor enhancing agents to the pressure vessel before application of pressure.Type: GrantFiled: December 15, 2000Date of Patent: July 30, 2002Assignee: Innovatit Seafood Systems LLCInventor: Ernest A.

Patent number: 6416711Abstract: A rotary sterilization system, a controller for use in the rotary sterilization system, and a method performed by the controller are disclosed. The system, controller, and method are used to administer a sterilization process performed on a line of containers and provide on-line handling of a deviation in a scheduled parameter during the process. The containers contain a shelf stable food product that is to be sterilized in the sterilization process. In addition to the controller, the rotary sterilization system includes a rotary sterilizer. The controller controls the rotary sterilizer in performing the sterilization process according to scheduled parameters. When a deviation in a specific one of the scheduled parameters occurs, the controller identifies those of the containers that will in response have a total lethality predicted to be delivered to them during the sterilization process that is less than a predefined target lethality.Type: GrantFiled: November 6, 1998Date of Patent: July 9, 2002Assignee: FMC Technologies, Inc.Inventor: Zhijun Weng

Patent number: 6410071Abstract: In a method and control system for controlling pasteurization of a food product, the internal temperature of the product, at least one pasteurization property change rate of the product based on the internal temperature of the product, and a cumulative pasteurization property change as a function of the pasteurization property change rate and time are at least periodically determined. A value of the cumulative pasteurization property change is at least periodically compared to at least one predetermined value, and a signal is generated when a predetermined relationship arises between the cumulative pasteurization property change value and the predetermined value(s). A cooked food product is preferably pasteurized at a temperature below the temperature at which it was cooked.Type: GrantFiled: July 10, 2000Date of Patent: June 25, 2002Inventor: Louis S. Polster

Patent number: 6391596Abstract: The present invention is related a high viscosity xanthan and processes for producing said high viscosity xanthan. In particular, the invention relates to a process for increasing the viscosity of xanthan comprising the steps of: (i) diluting xanthan in a fermentation broth with more than 30 percent by volume of a diluent to said fermentation broth volume; and (ii) pasteurizing said diluted xanthan fermentation broth. A particularly preferred pasteurization process is to utilize steam from a direct steam injection system. Xanthans with increased viscosities have improved product functionality for a number of different commercial applications are produced using the processes of the present invention.Type: GrantFiled: September 19, 2000Date of Patent: May 21, 2002Assignee: CP Kelco U.S., Inc.Inventors: Todd A.

Patent number: 6387430Abstract: 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.Type: GrantFiled: July 28, 1999Date of Patent: May 14, 2002Assignee: Purely Supreme Foods, LLCInventors: Thomas D.
