sausage casing| Is the skin on the sausage edible or not?

When people hear the word "man-made", they worry about quality problems. Does it contain harmful substances? Good artificial casings, such as collagen casings, are made from livestock skin, fields, tendons,s and other raw materials to change their form through advanced technology so that it is more in line with the demand of mass production. But there are also inedible collagen casings. Inedible collagen coats are thicker and larger in diameter and are mainly used to dry intestines.

Edible casings also: cellulose casings and plastic casings, these two types of casings have toughness, and shrinkage, the coloring is good, and the surface can be printed. Most of the sausages and hams on the market with printed text advertisements are not edible casings.
