Pork Mechanically Separated Chicken

Mechanically separated meat (MSM) is a paste-like, processed meat product made from the meat trimmings left on animal bones after deboning. The meat is scraped from the bones using a mechanical process, often resulting in a texture and appearance similar to a paste. It is commonly made from chicken or pork.

MSM is used as a lower-cost ingredient to add protein and texture to processed meat products. It is often found in items like hot dogs, sausages, deli meats, and some frozen pizzas. Its neutral flavor allows it to blend well with other ingredients.

In the US, mechanically separated meat is regulated by the USDA. The FDA has not specifically evaluated it for GRAS status or as an approved additive. While generally considered safe to consume when produced under sanitary conditions, its nutritional profile can differ from whole muscle meat, often being higher in fat and lower in protein per serving. JECFA and EFSA have evaluated various meat processing techniques and additives, but specific evaluations of MSM's health impacts at typical consumption levels are not widely publicized.
