Abstract
A method for the separation of fat from meat. The method includes providing individual pieces of meat containing lean and fat; subjecting the individual pieces of meat to cooling for a time sufficient to produce a difference in temperature between the fat and lean, wherein the fat is cooled such that the fat is friable and crumbles into finer particulates when subjected to a crushing force and the lean is cooled to a higher temperature than the fat and the lean is able to withstand a similar crushing force without substantially crumbling into smaller particulates; and with the fat and lean at the temperatures produced, subjecting the individual pieces of meat to a crushing force to separate particulates of fat from the individual pieces of meat.
