What is the casing made of, and what is the raw material of the casing?

Casings can be broadly divided into natural casings and artificial casings. Natural casing, mainly using the longest small intestine in animal internal organs, now generally use the small intestine of sheep so it is also called sheep casing, pig small intestine as casing is called pig casing. In the past, cow intestines and horse intestines were also used as casings.

These natural casings are characterized by good air permeability, so after the product is properly dried, it is smoked, and the smoked ingredients adhere to the product to get the flavor that people like, and the casing can be eaten directly. Artificial casings are divided into breathable casings and non-breathable casings. Breathable casings can be divided into edible and non-edible casings, edible casings are made of animal skin, etc., and their properties are similar to natural casings, we call them collagen casings, which are characterized by breathability and edible.

Non-edible casings mainly include cellulose casings and cellophane, which can be divided into cellulose casings and fibrous casings, which are characterized by breathability but inedible. At present, there is also a kind of non-edible casing made of plastic, which is also breathable and smokeable, so it is named smokeable plastic casing. Non-breathable casings are mainly plastic casings, which can be divided into polyvinylidene chloride (PVDC) casings and nylon casings according to different materials, and can be divided into sheet casings and cylindrical casings according to different shapes.

This kind of casing has many varieties and specifications, can be printed, easy to use, clean and beautiful, and is suitable for cooking products.

Casings are animal products made by scraping the large and small intestines of domestic animals. It is mainly used as a coat for filling sausages and enemas;

No casing makes it as delicious as it is, and the key cost is relatively low
