p>Shrimp thread is the digestive tract of the shrimp, on the back of the shrimp. Some are very dark and some are so light in color that they are barely noticeable and have something to do with the dirt in them. Shrimp threads can affect the taste, so some people remove them.
Removing shrimp threads, both because of the dirt in the shrimp's digestive tract (this is the same reason we remove fish gills and crab gills), but also because the threads affect the taste, especially when steamed in white and simmered in wine. Shrimp threads contain bitter substances that can mask the sweet flavor of fresh shrimp when heat is applied.... If you are doing spicy and stir-fried, because of its own strong flavor, to go to the shrimp line is relatively indifferent.
