Abstract: A process is disclosed for the calculated removal of fat from pork skin. Pork skin is subjected to tumbling cycles during which the pork skin is tumbled first in warm water and subsequently in warm water containing salt and concentrated laundry detergent. As this two step cycle is repeated, fat contained within the pork skin separates and is drained from the pork skin with the rinse water. The cycle may be repeated until the pork skin contains a desired percentage of fat. The process does not require that the pork skin be ground or otherwise comminuted in order to selectively remove fat from the material, nor does the process use harsh solvents or chemicals that might render the pork skin inedible or toxic. Because the process is all natural, the reduced fat whole pork skin is edible and may be formed into a variety of canine treats through additional processing and cooking.
