Publication number: 20170143013Abstract: A process for preserving fresh meat which includes the steps of a) packaging fresh meat in a sealed package; b) placing the packaged fresh meat in a pressurization vessel and closing the vessel; c) pressurizing the pressurization vessel containing the packaged fresh meat to an elevated pressure of at least 50,000 psi pressure so that the packaged fresh meat is placed under the elevated pressure; d) maintaining the elevated pressure on the packaged fresh meat for a time of from 1 to 300 seconds and at a temperature of from ?2° C. to 8° C.; e) reducing the pressure on the packaged fresh meat to ambient pressure; and f) removing the meat from the pressurization vessel. Pathogens are effectively killed using this process, providing manufacturing efficiencies and longer product shelf life as compared to other meat handling procedures.Type: ApplicationFiled: November 28, 2016Publication date: May 25, 2017Inventors: Russell Lanzrath, David R.

Publication number: 20100056898Abstract: 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.Type: ApplicationFiled: June 13, 2006Publication date: March 4, 2010Inventors: David R.
