What is bovine collagen made of (intestinal substitute for fried sausages, Hungarian balaton salami, etc.)? Is it true that its use in the food industry was banned until last year?
Collagen-based intestines are also called skin fiber casings. The raw material for skin fiber casings is animal skin. The so-called hide gap is separated (= split off) from the inside of the cattle hide in the tannery. The gap is then crushed and pressed through perforated screens. This creates fibers that are then formed into strands and hardened.
Collagen sausage casings can be edible and non-edible. As a rule, they have a relatively coarse consistency and are very thick-walled and therefore not suitable for consumption. There are also thin-walled, edible skin fiber casings that are used for small-diameter sausages. The manufacturer must indicate on the packaging if the sausage casing is not edible.
This type of artificial casing is used as an alternative to natural casings for sausages.
