Patent number: 6054153Abstract: A modified atmosphere package includes first and second compartments separated by a partition member that is substantially permeable to oxygen. The first compartment contains an oxygen scavenger activated with an oxygen scavenger accelerator. The second compartment contains a retail cut of raw meat. Various techniques are employed to rapidly reduce the oxygen level in the second compartment below pigment sensitive levels so that the growth of metmyoglobin is inhibited. Some of these techniques increase the flow of oxygen from the second compartment to the first compartment through the partition member to a level inhibiting the formation of metmyoglobin in the raw meat.Type: GrantFiled: April 3, 1998Date of Patent: April 25, 2000Assignee: Tenneco Packaging Inc.Inventors: Daniel G. Carr, Glenn C. Castner, Gary R. DelDuca, Rollie H. DeMay, Alan E. Deyo, Stephen L. Goulette, Darryl P. Hansen, Vinod K. Luthra, Allen J. Norby, Robert A. Sloan, Jill F. Thompson

Patent number: 5958479Abstract: An antioxidant composition which utilizes a desiccant carrier impregnated with a suitable fat soluble antioxidant is conveniently contained within a vapor permeable housing to prevent homogeneous mixing thereof with a stored product when the composition is provided in granulated form. The desiccant carrier is selected from a group of suitable hydrophilic materials which demonstrates the capacity for reducing levels of atmospheric moisture by absorption thereof, including for example, silica gel. The housing may conveniently be a sealed packet formed from a porous fiber material, such as, for example, that commonly used for fashioning tea bags and the like. Alternatively, the housing may include an enclosed perforated structure, the perforations of which are smaller than the granules of the contained composition. Where the composition is provided in the form of a unitary body, a housing need not be used.Type: GrantFiled: April 7, 1998Date of Patent: September 28, 1999Assignee: American Roland Chemical CorporationInventors: Michael Roitberg, Mel Blum

Patent number: 5948457Abstract: A modified atmosphere packaging method creates a modified atmosphere in a package including an inner package and an outer package. The inner package is composed at least partially of a polymeric material substantially permeable to oxygen, while the outer package is composed of a polymeric material substantially impermeable to oxygen. After a food product such as raw meat is placed within the inner package, the inner package is flushed with a desired mixture of gases to substantially remove oxygen from the inner package. The flushed inner package is then sealed and inserted into the outer package without sealing the outer package. Next, the outer package is flushed with the desired mixture of gases to substantially remove oxygen from the outer package. After flushing the outer package, the outer package is sealed. An oxygen scavenger is provided in the package to substantially absorb any residual oxygen within the package.Type: GrantFiled: June 9, 1998Date of Patent: September 7, 1999Assignee: Tenneco Packaging Inc.Inventors: Gary R. DelDuca, Alan E. Deyo, Vinod K. Luthra, Wen P. Wu

Patent number: 5821266Abstract: Dehydroshikimates are used as antioxidants for oxidation susceptible compositions, as well as for inhibiting oxidative physiological processes. Particularly, the parent acid and its derivatives find application in inhibiting the oxidation of food substances, feed, dietary supplements, oils, polymers, fuels, lubricants, cosmetics, medicinal agents, inks, dyes, and other oxidative sensitive products, over extended periods of time and at elevated temperatures. The subject compounds can be used at low concentrations.Type: GrantFiled: July 19, 1996Date of Patent: October 13, 1998Assignee: Michigan State UniversityInventor: John W. Frost

Patent number: 5770571Abstract: The present invention relates to compositions and methods for inhibiting the aging of amino-containing amino acid, peptides, proteins and biomolecules. Accordingly, a composition is disclosed which comprises an agent or compound capable of reacting with the glycosyl-amino moiety of the early glycosylation product (also known as the Amadori product or the Heyns product) formed by the reaction of glucose, or other reactive sugars, with an amino-containing peptide, protein or biomolecule, thus stabilizing this early glycosylation product, and preventing its further reaction to form open-chain, carbonyl-containing advanced glycosylation end products. Suitable agents may contain a reactive aldehyde group. A preferred agent is acetaldehyde. The method comprises contacting the target biomolecule with the composition. Both industrial and therapeutic applications for the invention are envisioned, as food spoilage and animal protein aging can be treated.Type: GrantFiled: November 15, 1996Date of Patent: June 23, 1998Assignee: The Picower Institute for Medical ResearchInventors: Anthony Cerami, Yousef Al-Abed, Richard J.
