Dried Shrimp
Dried shrimp is a shelf-stable seafood product made by sun-drying or heat-drying small shrimp, commonly used in Asian cuisines. It is a concentrated source of protein, sodium, and the vasoactive amine histamine.
Also known as: dried prawns, ebi (Japanese), har mi (Cantonese)

Dried shrimp are small shrimp (typically 1–3 cm long) that have been sun-dried or heat-dried to remove moisture, concentrating their flavor and extending shelf life. They originate primarily from Southeast Asia, particularly Vietnam, Thailand, and China, and are widely used as a seasoning, stock base, or textural ingredient in Asian dishes—including fried rice, broths, dim sum fillings, and condiments. They generally require rehydration before use in most cooked applications.
Dried shrimp are roughly 60–70% protein by dry weight, making them an extremely protein-dense food. They also contain significant amounts of sodium, cholesterol, and iodine. The drying and storage process can concentrate histamine, a vasoactive amine that can trigger headaches or flushing in sensitive individuals. The high sodium content and potential for elevated histamine mean they are not suitable for unrestricted consumption, particularly for those managing blood pressure or histamine sensitivity.
Sodium and Blood Pressure
A single serving of dried shrimp (approximately 1 tablespoon or 10 g) can supply a meaningful amount of sodium, depending on whether salt is added during processing. Unsalted or lightly salted products contain considerably less sodium than heavily cured commercial products. For individuals on sodium-restricted diets or managing hypertension, dried shrimp should be used sparingly as a flavoring rather than a primary ingredient. The American Heart Association recommends limiting sodium to less than 2,300 mg per day for most adults, with a stricter target of 1,500 mg for those with high blood pressure; dried shrimp can represent a substantial portion of either limit in a single meal.
Histamine Content and Sensitivity
Dried seafood products, including dried shrimp, can contain elevated levels of histamine due to bacterial decarboxylation of the amino acid histidine during storage and drying. Individuals with histamine intolerance or those taking monoamine oxidase inhibitor (MAOI) medications should avoid or severely limit dried shrimp. Histamine sensitivity typically manifests as flushing, headache, or gastrointestinal symptoms within minutes to hours of consumption. Standard cooking or rehydration does not reduce histamine levels. Those with a shellfish allergy must avoid dried shrimp entirely, as the allergen proteins remain intact after drying.
Frequently Asked Questions
Is dried shrimp safe for people with shellfish allergies?
No. Drying does not remove or alter the proteins responsible for shellfish allergic reactions. Individuals with a diagnosed shellfish allergy must avoid dried shrimp entirely. If allergy status is unknown, consult a healthcare provider before first use.
Why does dried shrimp contain so much sodium?
Many dried shrimp products use salt during the drying and curing process to preserve moisture and inhibit bacterial growth. Salt also enhances the concentrated flavor. The result can be a product that supplies substantial sodium even in small portions, making it unsuitable as a staple food for those with hypertension or on sodium-restricted diets. Unsalted varieties are available and contain significantly less sodium.
Can I reduce histamine by cooking or soaking dried shrimp?
No. Histamine is a stable compound that forms during storage and drying due to bacterial enzymatic activity. Standard cooking, boiling, or soaking does not degrade or remove histamine to any meaningful degree. Those with histamine sensitivity or intolerance should avoid dried shrimp.
How much dried shrimp is a typical serving?
A typical serving is 1–2 tablespoons (10–20 g) when used as a flavoring or ingredient in broths or rice dishes. Even in these small amounts, dried shrimp can contribute a notable amount of protein and, depending on the product, a significant amount of sodium. Use should be measured and occasional rather than daily for most people, particularly those managing sodium intake.
