The pig's large intestine is delicious, but it is found that the surface is black, which makes people doubt and worry. In fact, this is because the pig's large intestine may be exposed to air during the production process, resulting in some dark oxides on the surface. If these large intestines are not thoroughly cleaned and cooked, they may contain some bacteria and other harmful microorganisms, which will do harm to human health. Therefore, it is recommended that you look for regular businesses when buying.

For black pig large intestine, pigment may be added during processing. Although these pigments form a layer of black on the surface of pig's large intestine, they are only visual contrast effects and are harmless food additives. However, consumers should also pay attention to brand reputation and product quality when choosing pig intestines. It is best to choose a merchant with at least a hygiene license to avoid buying unsafe products.

In short, there is no uniform standard for the large intestine of black pigs. When we look at the black pig's large intestine, we should be vigilant and buy carefully, and don't be greedy and cheap. If it is found that the surface color of the large intestine is too dark, it is recommended to choose a brand with "QS logo" because this logo is a symbol of consumer protection. At the same time, remember to sterilize during processing and cooking, so that delicious food can be presented to us.
