There are two types of casings: natural casings and artificial casings
1. The primary materials used for natural casings come from the intestines of animals, and the most commonly used ones are sheep intestines and pig intestines.
Advantages of natural casings: edible, good taste, breathable, good toughness, good shrinkage and expansion and elasticity, best for short-term use.
The disadvantages of natural casings cannot be ignored: it is not suitable for long-term storage, it is easy to breed bacteria, the caliber is not uniform, the output is small, and it is not suitable for large-scale processing in factories.
2. There are many kinds of artificial casings, collagen casings, fiber casings, cellulose casings, vegetarian casings, plastic casings, mesh casings, etc.
The most common type of plastic casings on the market are plastic casings. Except for the outer packaging, casings are also required when making sausages. These kinds of casings are usually used, such as collagen casings, fiber casings, cellulose casings, and vegetarian casings.
The advantages of edible artificial casings: Collagen casings are edible casings, which contain functional products with high protein, low sugar, and low fat.
Good taste and natural appearance
Stable and uniform diameter
Food Safety and Traceability
Hygiene (more bacteria in natural casings)
Can be customized as needed (size, shape, color, etc.)

Printable to create more personalized products
Halal and Kosher certifications are available
Flexibility: Can shrink together with sausages
Production of natural casings
In the natural casing industry, the animal's small intestine is divided into three layers: the outer casing, the middle casing, and the inner mucosa. Through a special scraper, the mucosa is extruded, the intestinal skin is peeled off, and the rest is the semi-finished casing.
The main differences between semi-finished casings and finished casings are caliber, holes, and appearance:
1. First of all, let’s talk about the caliber. Natural casings have the word “natural” and are grown from the belly of animals, so they have thicknesses and thicknesses. Taking pig casings as an example, the maximum caliber difference can reach more than 2 cm, so skilled workers are required to pick and choose. , to classify similar calibers.
2. The second is the hole. It is easy to break the small intestine and the semi-finished casing during the steps of taking the small intestine, transporting it, passing through the scraper, etc. Therefore, the hole on the semi-finished casing should be removed, and a hole casing should be removed Cut at the hole and cut into two casings without holes.
3. Finally, the appearance, the residual mucosa in the casing, or the color is black or too white, it is not a good casing (the normal color is milky white, light yellow, pink white), and the wrinkle or irregularity will also affect the appearance of the sausage.
The pig and sheep casings are selected by filling the cases with water, and the beef casings are thicker and carried out by aeration. After the cases are selected, they are pickled with salt and put into special casing barrels for sale.
Artificial casings include collagen casings, cellulose casings, and plastic casings.
