Patent 7485331 was granted and assigned to Hydrodyne on February, 2009 by the United States Patent and Trademark Office.
Meat such as beef or pork is tenderized by first subjecting it to Hydrodyne treatment, followed by injecting the meat with an aqueous marinade. In this way, the quantity of marinade which is retained in the meat without purge can be increased by 40% to a marinade content of about 14%.
