Shrimp line is the digestive tract of shrimp, on the back of shrimp. Some are very dark, some are very bright and almost invisible, which is related to the dirty things inside. Shrimp line is removed because there is something dirty in the digestive tract of shrimp.

This is the same reason that we remove fish gills and crab gills), and it is also because shrimp lines affect the taste, especially when steamed in white and braised in wine. Shrimp thread contains bitter substances, which will mask the sweetness of fresh shrimp under the action of heat. If it's spicy and stir-fried, it doesn't matter whether you go to the shrimp line or not, because the taste is strong.

Method for removing shrimp line:

Method one

Insert the toothpick into the second section of the shrimp back, cut it open and pick out the shrimp line directly.

Method 2

Cut off the head and tail and squeeze out the shrimp line and dirt by hand.

Method 3

When picking shrimp heads, don't unscrew them all at once. Turn the shrimp head slowly and the shrimp intestines will be pulled out.

Method 4

Remove the shrimp head and shell, leaving the tail, cut along both sides of the shrimp back, and push the shrimp back away by hand. Have you seen the shrimp sausage? Just take it out by hand.
