Abstract From the Canadian patent

A process for making a low fat meat product includes grinding the meat having less than 50% fat to reduce the meat to a small particle size. The meat is then heated to a target temperature less than 100° F, which is hot enough to melt the fat and low enough not to denature the meat. The meat is then placed in a centrifuge and subject to centrifugal separation, thereby making a low fat meat product and an oil product. The low fat meat is removed from the centrifuge and chilled and the oil product is removed and may later be subject to a polishing operation. In addition the, process may include mixing the meat after it has been heated and before being placed into the centrifuge.

Why it's free to use

  • Filed November 23, 1994 and granted April 20, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 23, 2014.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 23, 2016.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
