Can Sausage Casings Be Eaten?

There should be many friends who like to eat sausages. It is estimated that many people have been entangled in whether the outer casing can be eaten. Most people wonder when they think about this question, what kind of material is this thin coat made of? With this kind of doubt, but also for my own health considerations, every time I cook, I choose to peel it off and discard it. First of all, I feel that it is not clean to be exposed, and then I am unwilling to try unknown things. With this question, check the information to see what is made.

It turns out that outside of our common sausages, casings are divided in detail, basically divided into two types: natural and artificial. The sources are also extensive. The small intestines of animals such as pigs, cattle and sheep can be used after treatment, but pig casings are commonly used. However, the length of the small intestine is actually relatively short, and each casing can be made using several pieces. After slaughtering the fresh small intestine, the first step is to remove the various messy tissues inside, and what remains is the almost transparent tough film, which is successfully made. The more expensive Sichuan sausages or Guangwei sausages mostly use this pure natural pig small intestine.

Besides, the sausages we buy in supermarkets are cheaper sausages with various flavors. These casings are collectively called artificial casings. But it is divided into three categories in detail, namely collagen casings, cellulose casings and plastic casings. Only one of them is edible, and that is collagen. This kind of raw material is mainly made from animal skins, which has the permeability similar to the small intestine and can be directly eaten. Cellulose is also good in terms of air permeability, but it is not edible or smoked and must be removed before cooking. Plastic is also breathable. If you need a smoking process and reduce costs, this is the first choice, and it is often called smokeable plastic casing.
