PURPOSE: To obtain a new kind of food soft and easy to eat, by fiberization of non-fibrous livestock meat or fish meat.

CONSTITUTION: Fish meat or livestock meat is first made pasty and then incorporated with collagen fibers extracted from an animal followed by kneading homogeneously, and, according as needed, further incorporated with seasoning, coloring matter and/or spice to obtain a preparation, which is then heated to 65°C or higher to effect shrinkage of the collagen fibers and fine fiberization of the kneaded meat as a whole.
