The main ingredient in slim jims is MSM.


Mechanically separated meat (MSM), also known as mechanically recovered/reclaimed meat (MRM), is a paste-like meat product produced by forcing beef, pork or chicken bones, with attached edible meat, under high pressure through a sieve or similar device to separate the bone from the edible meat tissue. Mechanically separated meat has been used in certain meat and meat products since the late 1960s. This product can be contrasted with meat extracted by advanced meat recovery systems.
