What is the "black vein" in shrimp? 😱😱🤯🤯What if you like it? Type "List" and you'll see the details in the first comment.

It is simply a receptacle for waste and residue. Eating it does not provide protein or vitamins; it only introduces unwanted impurities.

Summary: When should it be withdrawn and when can it be ignored?

In large shrimp (jumbo): It should always be removed, since the digestive tract is large and the sand inside is very visible and unpleasant to the palate.

In very small shrimp: Removing the carcass from each shrimp can be difficult and tedious. Since the channel is very thin, its effect on taste and texture is minimal and imperceptible, which is why many people ignore it in this case.
