There are two kinds of cattle shutters, the cow shutters that grow up eating feed are black, and the cow shutters that grow up eating grain crops are yellow.

Cow shutters are cow stomachs. Aliases: louver, belly, cow stomach, hairy belly.

It is one of the internal organs of the cow, that is, the third septal valve (omasum) in the stomach of the cow. The valve stomach is leaf-shaped, and its function is to absorb water and the acid produced by fermentation. Beef shutters can be used as food ingredients, generally used for hot pot, stir-fried food and other purposes.

Cantonese people will also steam it as a snack when drinking tea.

Fresh beef shutters must be processed to be crispy and delicious. Tripe contains protein, fat, calcium, phosphorus, iron, thiamine, riboflavin, niacin, etc., which has the effect of nourishing the spleen and stomach, nourishing qi and nourishing blood, replenishing deficiency and improving essence, quenching thirst and dizziness, and is suitable for people with deficiency, lack of qi and blood, malnutrition, and weak spleen and stomach after illness.

Cattle are ruminants, and unlike other domestic animals, the biggest feature is that they have four stomachs, namely the rumen, the net stomach (honeycomb stomach), the valve stomach (louvered stomach, commonly known as the cow shutter) and the wrinkled stomach. The first 3 stomachs do not have gastric glands and do not secrete gastric juice, which are collectively referred to as the forestomach.

The fourth stomach has gastric glands that secrete digestive juices, similar to the stomachs of pigs and humans, so it is also called the true stomach. The roughage ingested by cattle is mainly fermented and decomposed by microorganisms in the rumen into substances that can be absorbed and utilized.

Cow shutters are not all white, and it can be said that there are very few white. Natural cow shutters are available in any color, black, brown, green, and gray. The white ones are bleached.
