Abstract
One or more portions of whole muscle meat are injected with a liquid comprising oil and water, conveniently also containing flavoring materials and/or flavor enhancing materials. The portion or portions are placed in a tray, and conformed generally to a desired final shape by the use of a low pressure, and are frozen to a temperature of minus 18.degree. C. into a condition in which the meat is mechanically rigid. The body of meat is pressed under high pressure into the final shape to produce a block of meat of substantially uniform cross-section. The block may be sliced to provide steaks of uniform thickness, uniform cross-section and uniform density, and may conveniently be vacuum sealed prior to cooking.
Claims12
A method of providing portions of meat of predetermined size comprising:
- (a) injecting a body of meat with a liquid comprising oil and water;
- (b) forming the injected body of meat into an initial shape;
- (c) freezing the shaped body of meat at a rate effective to limit the size of ice crystals formed within the body of meat;
- then
- (d) pressing the frozen body of meat into a desired shape under a pressure of 750 to 4000 psi, wherein the pressure is effective for producing liquification of ice in the body of meat such that muscle fibers in the body of meat are allowed to slip across one another without any significant disruption of muscle structure;
- (e) quickly releasing the pressure applied in step (d) to re-freeze the ice liquified in step (d) and to limit ice-crystal growth during re-freezing;
- and then
- (f) slicing the frozen body of meat into portions of desired size,
- wherein the method provides portions of meat without significant disruption of the muscle structure of the meat and which portions retain the texture of untreated meat.
