The main raw material for collagen casings is animal hide, and currently the main raw material used is cowhide.

  The main raw material for collagen casings is animal hide, currently primarily cattle hide. Collagen casings have the following characteristics:

  Collagen casings come in various lengths, diameters, and thicknesses; they are relatively strong; and product specifications are highly consistent and uniform.

  Collagen casings are food-grade and contain a large amount of amino acid nutrients. Consumption poses no harm to the human body.

  Due to their uniform and highly consistent quality, collagen casings can be easily compressed into tubes or rolled into cylinders for packaging, facilitating transportation and storage. They can be stored and transported at room temperature without special treatment, with a shelf life of two to three years.

  Casings originate from animal (primarily pig, cattle, and sheep) viscera. They are one of the earliest used casings and a traditional packaging material for sausages. Their characteristics include edibility, permeability, heat shrinkage, and adhesion to meat fillings. Adhesion.

  However, casings have the following drawbacks:

  Cleaning and processing animal intestines is laborious and hinders mechanization, resulting in high operating costs;

  Animal intestines contain many bends that are unfavorable for sausage production;

  The thickness of animal intestines varies depending on the animal and its part, and their strength also varies. These drawbacks hinder the standardization and mass mechanized production of sausages
