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.
