  • Patent number: 6610457
    Abstract: A bottom antireflective coating layer is made from the compositions of organic photosensitive materials that contain isoflavone chromophore by photolithography utilizing a deep ultraviolet light source for producing a submicro-level, large-scale integrated chip. A copolymer containing an isoflavone chromophore is used as a bottom antireflective coating layer for fabricating a 64-megabit or gigabit DRAM. The antireflective coating layer enables not only the suppression of reflections of light that occur under the substrate layer but also the removal of standing waves. Consequently, a high-resolution sub-micron of a 100˜200 nm integrated circuit is able to be stably formed. Therefore, it is possible to increase the production of semiconductors.

  • Patent number: 6605253
    Abstract: The presently disclosed disinfection process for use in the processing of foodstuffs is designed as an intervention step in poultry processing to allow for continuous on-line processing of poultry carcasses that may have accidentally become contaminated during the evisceration process. Such on-line processing is designed to replace the need for off-line manual washing and cleaning of the contaminated carcasses. By eliminating such off-line manual washing, food safety will be enhanced due to the elimination of the physical handling of carcasses and the cross-contamination that may result from such physical handling. An additional benefit is that the production process will also be able to run with a reduced number of interruptions, which will result in a more efficient production process.

  • Patent number: 6589580
    Abstract: A method and apparatus for applying a material to food products in a high speed packaging line at a controlled rate in compliance with applicable food-handling equipment standards, preferably in a liquid spray, without immersion, wherein the rate of application is sufficient for efficacy of the material without resulting in transfer of unacceptable quantities of the material or carrier to adjacent line components. The invention is particularly useful for spray application of a liquid antimycotic agent to cheese chunks, at a regulated rate that provides a sufficient surface concentration to inhibit mold growth on the surfaces of the cheese chunks after extended periods of exposure to ambient air, without unacceptable transfer of residue to adjacent components in the packaging line. The invention is preferably employed in application of natamycin to cheese chunks wherein a disk spray system applies a suspension of natamycin in an aqueous saline solution.

    Abstract: Plant essential oils and chitosan salts were tested individually and in combination against a postharvest pathogen Botrytis cinerea and two foodborne human pathogens Escherichia coli and Listeria monocytogenes. Four essential oils (cinnamon, allspice, savory, red thyme) in combination with two chitosan salts (chitosan sorbate and chitosan propionate) demonstrated synergistic antimicrobial activity against all three organisms. The synergistic combinations of essential oils and chitosan salts also demonstrated an eradicant activity against E. coli on apple disks previously inoculated with the organism. Synergistic combinations of essential oils and chitosan salts hold promise of giving superior control of both postharvest decay organisms and foodborne human pathogens.

  • Patent number: 5916620
    Abstract: A shelf-stable, uncooked or partially cooked moist pasta is produced by treating freshly extruded or sheeted pasta with steam to set the pasta surface, immersing the steam treated pasta in an aqueous solution containing acidulants and/or humectants, partially drying to remove surface moisture, sealing the pasta in a container, and thermally pasteurizing the pasta while it is in the container using conventional thermal processes or microwave treatment. The pasta thus produced is shelf-stable under non-refrigerated conditions and has an equivalent or better texture, color and flavor than commercially available, fresh refrigerated pastas.

  • Patent number: 5840356
    Abstract: Frozen fruit of at least one type is slowly thawed by refrigeration over a defined period of time, and then combined with a mix of 0.056% to 0.058% by weight of preservatives dissolved in purified water, 0.0% to 3.70% of natural sweetener or sweeteners, sufficient edible acid to give a pH range of about 2.3 to 3.8, and sufficient amounts of flavoring and coloring agent to give the desired flavor, color and consistency in the final product. The final fruit puree product has a brix value in the range of 6.0 to 25.0 which is a shelf-stable, ready to use fruit puree that does not require refrigeration.

  • Patent number: 5834093
    Abstract: A bilayer laminated medical dressing having a thermally expandable passage is provided. The medical dressing achieves gas permeability as a function of temperature by cutting a star-shaped hole through the dressing when the dressing is flat and relaxed. On warming, the leaves between the radial cuts of the star-shaped hole curl and increase the hole size. Such a material is useful as a medical dressing.

  • Patent number: 5753493
    Abstract: The instant invention is an egg wash decontaminating solution and process. The decontaminating solution and process allows for reducing the surface tension of a biofilm allowing for the removal of the biofilm and control of underlying bacteria. A solution of triterpene saponin provides the surface tension wherein an optional soft acid such as food grade sodium lactate operates to control the bacteria. The saponin further acts as a foaming agent providing visual indication of operation while holding matter in suspension.
