A process for producing a protein product for addition to raw meat wherein the source of the protein product is animal muscle or mechanically deboned meat. The animal muscle tissue is mixed with water and homogenized. Protein in the homogenate is solubilized. Solubilized homogenate is heated to a temperature required for pasteurization and/or sterilization according to known standards. The homogenate is then adjusted to a value at which the protein precipitates. The precipitate is free of bacteria and toxins and can be used as meat or added to raw meat for delivery to a consumer as uncooked meat.

A method to convert insects or worms into nutrient streams, such as a fat-containing, an aqueous protein-containing and a solid-containing fraction, includes (a) squashing insects or worms thereby obtaining a pulp, wherein the insects or worms are reduced in size, (b) heating the pulp to a temperature of 70-100 C., and (c) subjecting the heated pulp to a physical separation step, preferably decanting and/or centrifuging. The method does not comprise enzymatic treatment of the pulp. The fat-containing fraction comprises at least 80 wt. % insect or worm fat of which at least 40 wt. % are saturated fats. The aqueous protein fraction can be dried to obtain dried protein material, which contains at least 50 wt. % insect or worm protein-derived matter and at most 25 wt. % insect or worm fat based on dry weight. The protein has a pepsin digestibility of at least 50%. The resulting nutrient streams can be used in food, petfood, feed and pharmaceutical industry.

A precipitated purge protein is obtained from animal muscle tissue purge. Animal muscle tissue purge is mixed with a food grade acid to form an aqueous acidic solution of animal muscle tissue purge. The acidic solution is mixed with a food grade base to precipitate the protein in the solution. The precipitated protein then is recovered.

A process for the production of fat-encapsulated follistatin. The process includes steps of a) metering fat having a melting point of at least 40 C. into an extruder, b) heating the fat in the extruder during rotation of the at least one screw, c) metering the follistatin into the extruder barrel to produce a flowable mixture, d) cooling the flowable mixture in a downstream adjacent section of the extruder barrel, e) subsequently discharging the mixture through an extruder die, and f) comminuting the mixture after it discharges from the extruder die.
