1. The main raw material of artificial casings is plastic or paper. Most of the time, sausages use natural casings, and there is no problem with artificial casings from regular channels. When buying food, don’t buy some Sanwu products, but buy things through formal channels.

2. Sausage casings can be divided into two types, one is natural and the other is artificial. Natural casings use animal intestines, among which pig small intestine is often used. But if you use pig small intestine, you need to pay more attention to the clarity. Not only must it be cleaned, but the mucous membrane inside must also be removed, otherwise the smell will be unpleasant.

3. During the production process of sausage casings, the outer layer of the casing is removed. Without the outer and inner layers, the middle layer is indeed very thin. Making casings is more troublesome, but it tastes healthier and more hygienic.
