Different parts: The large intestine of pigs usually refers to the digestive organs of pigs, including the intestines and stomach of pigs, and is an important part for transporting and digesting food. It usually has a thick outer skin and a thick inner membrane, which can absorb and digest nutrients in food. Seven-inch pig intestine is one of the digestive organs of pigs, which is different from pig intestine. Mainly responsible for transporting and digesting food, there is no thick outer skin and thick inner mucosa like pig intestines.

Cooking methods are different: the pig's large intestine plays the role of storage and digestion, so the taste is very strong. In cooking, it is necessary to use heavy-flavored seasonings to make various foods, such as stir-fried pork intestines and braised pork intestines. Seven inches only plays the role of transportation, and its taste is not as strong as that of pig's large intestine, so it is often used to make snacks or pickles in cooking.
