Mechanically Separatedturkey

Mechanically separated turkey (MST) is a paste-like poultry product made from turkey carcasses after the valuable meat has been removed. It is produced by forcing the bones, skin, and remaining flesh through a sieve or grinder under high pressure. This process breaks down the tissues, creating a smooth, uniform texture.

MST is primarily used as a lower-cost ingredient in processed meat products like sausages, hot dogs, and deli meats. Its fine texture and binding properties help improve yield and consistency in these foods. Manufacturers use it to reduce overall product cost while maintaining a desirable mouthfeel.

Mechanically separated turkey is permitted for use in the U.S. by the FDA. It is considered a poultry product and is subject to USDA regulations. While it is a source of protein, its nutritional profile may differ from whole muscle meat due to processing. JECFA has evaluated many food additives, but specific evaluations for MST itself are not typically found as it's a food ingredient rather than an additive. There are no widespread health controversies specifically linked to the consumption of MST at typical intake levels.
