  • Publication number: 20150024667
    Abstract: A method for tenderizing meat of a red meat slaughter animal including separating a vertebral column of the animal, hanging the carcass by pelvic suspension and applying electrical stimulation to the animal's musculature. Vertebral column separation is performed prior to the onset of rigor mortis to enable stretching of muscle fibers in the carcass. Electrical stimulation is focused on a midsection of the animal.

  • Patent number: 8080270
    Abstract: A low temperature rendering process for converting animal trimmings to meat product which can be classified as finely textured meat. The low temperature rendering process includes steps of surface treating the trimmings to kill organisms which may be present on the surface of the trimmings; heating the surface treated animal trimmings in a heat exchanger having a first-in and first-out arrangement to provide heating of the animal trimmings to a temperature in the range of about 32° C. to about 43° C.

  • Publication number: 20100209568
    Abstract: The present invention includes a method for preparing a meat product that includes subjecting meat material to ultrasonic energy to reduce the microbial content of the meat material. One embodiment of the method includes subjecting the meat material to ultrasonic energy further comprises subjecting the meat material to about 1×10?4 to about 1 kilowatt-hour ultrasonic energy per liter meat material. In other embodiments the application of the ultrasonic energy can be varied in terms of energy, duration time, frequency, and temperature to achieve the desired results.

  • Publication number: 20100136696
    Abstract: An apparatus and method for detecting contaminants in a food product having an irregular shape is described. The apparatus comprises a contaminant detection device constructed and arranged to detect contaminants in a food product when the food product enters a zone of operation relative to the contaminant detection device. A conveyor belt is electrically coupled to the contaminant detector. The contour filler is operably connected to the conveyor bell and contaminant detector, and positions the food product within the zone of operation. The contour filler may retain the food product and fill the cross sectional area of the zone of operation to enhance contaminant detection. The contour filler may rotate the food product relative to the contaminant detector.

  • Publication number: 20100056898
    Abstract: An age of an animal or animal carcass is estimated using a measurement or measurements of physical properties of the animal or carcass. A correlation between at least one physical property or characteristic and the animal's age is determined. A measurement of the at least one physical property or characteristic is made using non-invasive technology. An estimated age is then determined comparing the measured at least one property to the correlation of property and age.

  • Patent number: 7108882
    Abstract: A method for surface treating animal tissue is provided by the invention. The method includes the steps of providing animal tissue having an average size of between about 0.5 inch and about 16 inches in length, introducing the animal tissue into a bath provided at a temperature of between about 80° C. and about 150° C. for between about 25 seconds and about 150 seconds, and recovering the animal tissue from the water bath. A pasteurization unit is provided for continuous processing of animal tissue.

  • Patent number: 6949265
    Abstract: A low temperature rendering process for converting animal trimmings to meat product which can be classified as finely textured meal. The low temperature rendering process includes steps of surface treating the trimmings to kill organisms which may be present on the surface of the trimmings; heating the surface treated animal trimmings in a heat exchanger having a first-in and first-out arrangement to form a heated slurry; separating a solids stream and a liquids stream from the heated slurry, the solids stream containing an increased amount of protein and the liquids stream containing an increased amount of tallow, separating a heavy phase and a light phase from the liquids stream, the heavy phase containing an increased amount of moisture and water soluble protein, and the light phase containing an increased amount of tallow, and combining the solids stream and the heavy phase to form a meat product.
