1. A process for producing fat-encapsulated follistatin, the process comprising the steps of
a) metering fat having a melting point of at least 40° C. into an extruder,
b) heating the fat to a melting temperature of the fat in the extruder during rotation of a screw of the extruder,
c) metering follistatin into an extruder barrel of the extruder to mix with the fat at the melting temperature of the fat and produce a flowable mixture of the follistatin and the fat,
d) cooling the flowable mixture in a downstream adjacent section of the extruder barrel to a temperature of at least 10 K below the melting temperature of the fat to form a cooled mixture,
e) subsequently discharging the cooled mixture through an extruder die, and
f) comminuting the cooled mixture after discharge from the extruder die to produce pellets of fat-encapsulated follistatin.
