Fibran artificial casings are a key product in the production of cured sausages, certified by the Ministry of Health for human consumption. Made mainly from collagen (74.7%) and glycerin (18.0%), they offer high elasticity, adhesion and permeability characteristics, suited for the international meat processing industry. Their use requires pretreatment in brine to optimize properties during stuffing, using a mixture of water and fine salt at a concentration of 12.5 to 17.5%.
