Meat slurry
From Wikipedia, the free encyclopedia
A meat slurry, reconstituted meat, or emulsified meat, is a liquefied meat product that contains less fats, pigments and myoglobin than unprocessed dark meats. Meat slurry also eases the process of meat distribution and is more malleable than dark meats.
Meat slurry is not designed to sell for general consumption; rather, it is used as a meat supplement in food products for humans, such as chicken nuggets, and food for domestic animals. Poultry is the most common meat slurry; however, beef and pork are also used.
[edit] Properties and production
Dark meat from poultry is often viewed as less palatable because of its color, low plasticity and high fat content. These characteristics are caused by myoglobin, a pigmented chemical compound found in muscle tissue that undergoes frequent use. Because domestic poultry rarely fly, the flight muscles in the breast contain little myoglobin and appear white. Dark meat which is high in myoglobin is less useful in industry, especially fast food, because it is difficult to mold into shapes. Processing dark meat into a slurry makes it more like white meat, easier to prepare and more attractive.
The meat is first finely ground and mixed with water. The mixture is then used in a centrifuge or with an emulsifier to separate the fats and myoglobin from the muscle. The product is then allowed to settle into three layers: meat, excess water, and fat.
The remaining liquified meat is then flash-frozen and packaged.
