Cows have four stomachs, namely rumen, reticulum, flap stomach and abomasum. Rumen, reticulum and flap stomach have no gastric glands and do not secrete gastric juice, and their functions are similar to those of esophagus. There are gastric glands in abomasum, which can secrete digestive juice, similar to human stomach, also called abomasum. Because of the different structures, the four stomachs have different tastes.
Rumen is what we often call tripe, with a pimple-like protrusion on the surface and a hard taste. Suitable for stewing, boiling and cold salad.
Net stomach, also known as honeycomb stomach, is what we often call money belly, honeycomb belly and hemp belly. There are honeycomb and reticular protrusions on the surface, and the taste is tough, because the nested structure can effectively retain the juice, which is easy to taste and suitable for stewing.
Flap stomach is what we often hear, such as hairy belly and burst belly, commonly known as tripe and tip of belly. Among them, there are many leaves with different sizes, and the surface presents a large number of thin petals with small protrusions, which makes the taste crisp. Moreover, because of the multi-petal structure and small protrusions, the juice retention ability is quite strong, which is suitable for mixing cold dishes or hot pot. However, the flap stomach is thin and easy to overcook, so attention should be paid when cooking.
The abomasum is also called tripe and shagua tripe. It not only has the toughness of ox grass belly and money belly, but also has rich fold structure, which is suitable for stewing.
