Meat: Color Myoglobin meat heme-pigment color Purplish-red Hemoglobin blood pigment Oxymyoglobin air combines with meat Bright in its oxidized form Metmyoglobin major discoloration Ferrous to ferric state High temperatures, microorganisms and light speed the reaction

leat for industrial processing is usually frozen in the form of carcasses, quarters or boned out primals in 25 kg cartons. Most bulk meat, consumer portions and meat products are frozen in air blast freezers. Some small ind viduals items, for example beefburgers, may be frozen in cryogenic tunnels and a small amount of offal and other meat is frozen in plate freezers. It is not unusual for meat to be frozen twice before it reaches the consumer During industrial processing frozen raw material is often thawed or tem-

Thermophysical properties of meat In chilling, freezing, thawing and tempering processes heat has either to be introduced or to be extracted from the meat to change its temperature The rate at which heat can be removed or introduced into the surface of meat is essentially a function of the process being used, for example air blast, plate, immersion, and so on. However, the rate at which heat can flow from within the meat to its surface is a function of the thermophysical prop- erties of the meat. If we continue to
