If the skin of Pipi shrimp is gone, it may be caused by stale or frozen. The stale Pippi shrimp is loose and easy to cause empty shells. In addition, if the shrimp is frozen and thawed, the meat will become soft and easy to form empty shells. If Pipi shrimp is cooked, it may also cause the meat to become tight and form an empty shell.

It should be noted that the meat quality of Pipi shrimp itself is relatively small. After freezing and thawing, the meat is softer and easier to form empty shells. Therefore, when buying and cooking Pipi shrimp, fresh and fleshy individuals should be selected to ensure the taste and quality.
