Sixteen ounces (1 pound) of raw boneless, skinless chicken breast will therefore yield about 12 ounces of cooked chicken. water expelled from meat during cooking is associated with collage shrinkage, probably basement membrane collagen shrinkage, which is believed to be at a maximum between 57 and 63 0 C. The moisture released during cooking is not only due to the tightening of the muscle structure, but also due to the proteins decrease in water holding capacity which occurs when muscle proteins become denatured. https://doi.org/10.1016/j.meatsci.2006.01.011.

Typically, higher cooking temperatures result in greater shrinkage so you can cook the meats at a lower temperature can reduce moisture loss to some extent. When heated, the protein break apart and contracts. MCS is the difference between the raw and cooked areas of the meat sample, expressed as a percentage of the raw area. The latent heat on the exterior of the meat will continue to travel to the thermal center of the meat until the temperature equilibrates, and this usually takes about 2-5 minutes in steaks. A moderate temperature helps them to retain moisture and weight. Even meat cooked in liquid will dry out although not as quickly. Multiply the shrinkage rate by 100 to find the shrinkage as a percentage. Beef meat loses 37% of its mass when you barbecue it. When meat and poultry muscle fibers change their shape during cooking, shrinkage inevitably occurs. That’s because the honeycomb air pockets in bones make poor conductors of heat. Shrinkage percentage includes trim loss and the difference between the precooked and the as-served weight. Basically, the higher the cooking temperature, the greater the shrinkage. After it's cooked it's only half a pound. Commercial kitchens can’t afford to have roasts shrink and lose meat. The proposed MCS protocol permits us to measure cooking loss and to reduce cost and variability, moreover it could be improved to obtain color and marbling measurements by developing the image analysis software. Fat is dispersed in and around the muscle fibers. > 0.5% by weight). significantly. Chicken, whole shrinkage after boiling – 28%. Meats of different types and cuts shrink at different rates.

The protein is what holds meat together and gives it a firm, springy texture. Use wet heat. For each 3-ounce serving of cooked poultry, buy an extra ounce to allow for shrinkage and an extra 2 ounces to allow for bone. Discover (and save!)
