  • Patent number: 5962054
    Abstract: Conventional food treatment processes utilized for food preservation generally involve heat treatment and usually result in some degree of thermal damage. A process has been developed for the non-thermal treatment of liquid food products which results in a significant reduction in the microbial population, thus reducing spoilage and extending shelf life. The novel process involves the rapid application of electromagnetic energy (EME), such as microwave or radio frequency energy, and the simultaneous removal of any thermal energy which may be generated by the process through the use of circulating cooling medium and an efficient heat exchanger.

  • Patent number: 5945027
    Abstract: Halophilic bacteria have been shown to cause red heat on brine-cured hides, resulting in extensive damage to leather made from the hides. The addition of bile salts to raceways or to hides directly has been found to prevent the occurrence of red heat by inhibiting the growth of the halophilic bacteria. Bile salt solutions were added to cultures of Haloarcula hispanica, Haloferax gibbonsii and Haloferax mediterranei. Fresh hides were also cured in brine containing halobacteria and bile salts. In both instances, the presence of bile salts inhibited the growth of halobacteria, and hides cured in the presence of halobacteria did not develop red heat.

  • Patent number: 5937575
    Abstract: This invention provides apparatus and methods for stabilization of ultrasonically generated nutrient fog. To eliminate the sensitivity to the humidity and temperature of the intake air, the fog is recirculated from the growth chamber to the fog-generating reservoir. The chamber and reservoir are connected by a fog supply conduit and a fog return conduit which form a fog circulation circuit. The recirculation eliminates the fog density dependence on intake air humidity and stabilizes the amount of nutrients used. To monitor the fog density, this invention provides an optical fog density detector that operates by measuring the absorbance of the fog. The density detector can be coupled with the fog generator so that the rate of fog generation is responsive to the measured fog density. The detector can be coupled with an alarm to signal fog generator malfunction. This invention also provides fog concentration stabilization by using a large ballast reservoir connected to a fog-generating reservoir.

  • Patent number: 5895814
    Abstract: A method is described for the preparation of lactulose by isomerizing lactose to lactulose, followed by complexing lactulose to boric acid. The isomerization reaction is carried out in alkaline solution, and it is followed by splitting the lactulose-borate complex in acidic solution and separating the two components. Separation is achieved by crystallizing boric acid, filtering the crystals out of the product mixture, evaporating the product mixture to form a concentrate, recirculating the concentrate to the crystallization step where it is mixed with fresh reaction mixture in order to provide volume and nuclei for the crystallization of the boric acid in the reaction mixture, then passing the resulting mixture through another filtration step followed by an additional separation step by column chromatography.

  • Patent number: 5843429
    Abstract: Helicoverpa species constitute the most important group of crop pests throughout the world, and scientists have been pursuing the development of biocontrol agents effective for the control of these pests. A virus, the gonad specific virus (GSV), has been discovered which serves this purpose by infecting Helicoverpa species and generally rendering the insects sterile. Those insects which do not become sterile on infection act as carriers of the virus, spreading it among the insect population and producing infected progeny.

  • Patent number: 5824316
    Abstract: A foot-and-mouth disease virus has been genetically engineered by deleting the nucleic acid sequence encoding the leader (L) proteinase from an infectious cDNA copy of the viral genome and producing an L proteinase-deleted virus. The L proteinase-deleted viruses are able to assemble and grow in cells in culture, but, since they lack L proteinase, they are less toxic to infected cells within the animal, producing an attenuated infection. The recombinant virus can be formulated into an effective vaccine for the prevention of foot-and-mouth disease.

  • Patent number: 5816057
    Abstract: The invention provides a filter for removing liquid from an ice slurry. The filter includes a horizontal filter plate. The ice slurry is passed over the top of the filter plate. The filter includes a first stage where the liquid is removed from the ice slurry, thereby consolidating the ice particles into an ice bed. The liquid is removed by drawing the liquid out of the ice slurry through a set of slots in the filter plate by using a low suction pump. A second stage of the filter draws the remaining liquid entrained in the ice bed through another set of slots using a vacuum pump, which has a higher suction than the low suction pump used in the first stage. A clean water rinse may be sprayed on the ice bed in the second stage to improve the removal of liquid from the ice bed. The filter plate at the second stage may be heated to produce a rinse through the bottom of the ice bed.
