The invention relates to an extrusion production technique for meat simulated fibers, and belongs to the technical field of food science. A low-value meat raw material is used as a main raw material. The technique comprises the following steps of: adding auxiliary materials such as soy protein, animal dermal bone collagen, transglutaminase serving as meat protein coagulation additive, kelp glue serving as kelp extract and the like, performing recombination and cross-linking on multiple proteins and macromolecular polysaccharides by adopting double-screw extrusion technology (the rotational speed of screws is 280 to 450 revolutions per minute, the pressure of a micropore template is 1.7 to 6.0MPa at the temperature of between 150 and 200 DEG C, and the temperature of a cylinder is 170 DEG C), forming meat silk simulated fibers by extrusion, forming cross-linking reaction among meat protein molecules and in molecules, and reshaping micropore formed fibers to obtain recombinant meat food with good color, fragrance, taste and shape. The meat product produced by using the silk muscle simulated fibers produced by the technique is pure natural green food, does not contain chemical substances or preservatives, has the mouthfeel of real meat silks and the specific flavor of meat, has special fragrance and color at the same time, and can be absorbed more easily. Moreover, the added auxiliary materials such as collagen, kelp glue and the like form protein and polysaccharide polymers, so the nutritional components of the product are increased, the quality and structure properties of the product are greatly improved, the water holding property is improved, the problems such as gel cracking and the like are effectively avoided, the quality guarantee period of the product is prolonged, and the social benefit and the economic benefit of the product are increased.
