7 Effective Ways to Get Rid of Shrimp Odor at Home and Like a Pro

According to Saednews, Shrimp’s fishy odor usually comes from naturally occurring compounds in its tissues, particularly sulfur compounds and volatile amines. After shrimp are caught or removed from the cold chain, bacterial activity increases, producing the unpleasant smell commonly associated with fish and seafood. Other factors, such as old shrimp, improper refrigeration or freezing, incorrect thawing, overcooking, and prolonged exposure to heat, can also intensify the odor.

To eliminate the fishy smell, first check the shrimp’s quality and freshness, then follow the proper cleaning and marinating steps.

Method 1: Lemon Juice and White Vinegar

One of the simplest and most effective ways to reduce shrimp’s fishy smell is to use lemon juice or white vinegar. Their acidity can help neutralize some odor-causing compounds and reduce unpleasant smells.

Place peeled and deveined shrimp in a mixture of cold water and lemon juice or white vinegar for 15–30 minutes. A suitable ratio is approximately two tablespoons of lemon juice or vinegar per liter of water.

Important tip: Do not leave shrimp in the acidic solution for too long, as prolonged exposure can change its texture, making it excessively soft or rubbery. After soaking, rinse the shrimp with cold water and pat it dry.

Method 2: Cold Milk

Using milk is a traditional yet effective method for reducing shrimp’s fishy smell and improving its flavor. Milk may help reduce certain odor compounds while keeping the shrimp tender.

Place the washed shrimp in a bowl and pour in enough cold milk to cover them completely. Refrigerate for 20 minutes, then remove the shrimp and rinse with cold water.

This method works particularly well for shrimp with a mild fishy odor and can make the final dish taste milder and more pleasant.

Method 3: Yogurt, Onion, and Garlic

Many southern Iranian recipes use strained yogurt, onion juice, and garlic juice to marinate shrimp. These ingredients add aromatic flavors and may help reduce unpleasant odors.

To prepare the marinade, combine:

• 2 tablespoons of strained yogurt

• 1 tablespoon of lemon juice

• A little onion juice

• Salt

• Turmeric

Mix the ingredients with the shrimp and refrigerate for 30 minutes.

Once marinated, rinse the shrimp if desired and cook according to your recipe. This method is particularly suitable for grilled shrimp, breaded fried shrimp, and skillet dishes.

Method 4: Spices and Aromatic Ingredients

Spices play an important role in improving shrimp’s aroma and flavor. Ingredients such as turmeric, black pepper, garlic, ginger, cumin, dried coriander, and curry powder can help mask unpleasant odors and create a richer taste.

Before cooking, season the shrimp with a mixture of these spices, a little oil, and lemon juice. Refrigerate briefly to allow the flavors to develop.

Aromatic herbs and ingredients, including fresh dill, parsley, cilantro, and sautéed onions, can also improve the aroma and flavor of shrimp dishes.

Method 5: Salt and Cold Water

Briefly soaking shrimp in lightly salted water can help clean its surface and reduce some unwanted odors.

Dissolve one teaspoon of salt in one liter of cold water and soak the shrimp for approximately 10–15 minutes. Then rinse and pat dry.

Avoid using too much salt or soaking the shrimp for too long, as this may negatively affect its texture.

Method 6: Cook Shrimp Properly

Overcooking is one of the main reasons shrimp can develop a stronger, less pleasant smell. Excessive cooking can also make the meat tough and rubbery.

Shrimp cooks quickly over medium-high to high heat. It is generally ready when it turns opaque and pinkish and its flesh becomes firm.

To minimize unpleasant odors:

• Cook shrimp quickly over sufficiently high heat.

• Avoid adding excessive water while frying.

• Do not overcook the shrimp.

• Add a little fresh lemon juice at the end of cooking for a brighter flavor.

Method 7: Remove Shrimp Odor from Hands and Kitchen Utensils

After handling shrimp, its smell may linger on your hands and kitchen equipment.

To remove the smell from your hands, wash them first with warm water and soap. You can then gently rub your hands with lemon juice or a small amount of baking soda mixed with water. Ground coffee, white vinegar, toothpaste, and fresh lemon or orange peel are also commonly used to freshen hands.

Wash any dishes and cutting boards that have come into contact with shrimp using warm water and dishwashing liquid. A little vinegar may help remove lingering odors from suitable surfaces.

Common Mistakes When Removing Shrimp’s Fishy Smell

One common mistake is soaking shrimp in lemon juice or vinegar for too long. This can alter its texture and make its flavor excessively acidic.

Another mistake is cooking shrimp without removing the digestive tract. Although this is not always the main source of odor or bitterness, removing it can improve the shrimp’s cleanliness and overall eating experience.

Food safety note: If raw shrimp has a strong ammonia-like or rotten odor, feels unusually slimy, or has been stored improperly, do not try to mask the smell with seasonings. Discard it, as these signs may indicate spoilage. Fresh shrimp should have a mild, clean, ocean-like smell.
