Patent number: 7919129Abstract: System and method for applying an antimicrobial agent, such as acidified calcium sulfate (ACS), to unpackaged meat products, in order to eliminate or reduce existing food borne bacterial pathogens and to prevent their growth when the meat products are stored. A conveyor transports unpackaged meat products to a spray chamber having nozzles positioned above and below the conveyor and meat products. The conveyor can be a wire conveyor having wires having a thickness so that they can support the food items, which can be eight to ten pounds, while being small enough so that the they do not block ACS solution sprays from the bottom nozzles, or do so to a negligible degree. The lower nozzles spray ACS solution through apertures of the conveyor and onto at least the bottom surfaces of the unpackaged meat products. The solution is sprayed with a sufficiently high pressure and sufficiently small drop size so that the ACS solution penetrates into tissues of the unpackaged meat products.Type: GrantFiled: January 20, 2006Date of Patent: April 5, 2011Assignee: ConAgra Foods RDM, Inc.Inventors: Wayne P. Pruett, Jr., Kevin G. Mellor, Donald N. Sinnot, Gilbert L. Boldt

Patent number: 5554720Abstract: This invention relates to polymer compositions containing naphthalenedicarboxylic acid residues and having reduced fluorescence due to the presence of aromatic thioether compounds. More specifically, the polymer compositions contain poly(ethylene 2,6-naphthalene dicarboxylate) and 0.1 to 5 mole percent of an aromatic thioether compound. The pollers are useful for packaging applications where clarity and/or aesthetic appeal is important.Type: GrantFiled: December 21, 1994Date of Patent: September 10, 1996Assignee: Eastman Chemical CompanyInventors: Max A.

Patent number: 5514403Abstract: This invention is a method of substantially reducing and in some cases eliminating hazardous pathogens form the surfaces of food products. This is accomplished by moving the meat products into a treatment area and spraying the same with super heated steam preferably heated to between 250 and 300 degrees Fahrenheit for a period of 1 to 5 seconds depending on the food product being treated. The surfaces of the food products are then immediately cooled by applying a chilled fluid having a temperature of between 35 and 40 degrees Fahrenheit for a period of 5 to 10 seconds. Even though the super heated steam substantially reduces or eliminates hazardous pathogens on the surface of the food products, the cooling fluid allows such surface to maintain its natural color or bloom.Type: GrantFiled: October 4, 1994Date of Patent: May 7, 1996Inventors: Neil B. Webb, Jonathan N. Webb, Wayne P. Pruett, Jr.
