What Are Scallops?

Scallops are known as bivalve mollusks belonging to the family of Pectinidae. Scallops can swim short distances by opening and closing their shells. They can be sold as seafood and their brightly colored, fan-shaped shells are often used in ornaments. They are available in dry packed (without additives) and wet packed (treated with sodium tripolyphosphate) variants. In addition, scallops have many culinary applications. Scallops are available in different sizes and textures. Here is a list of the commonly available varieties.

Types Of Scallops

There are many types of scallops found in North America, including sea scallops, bay scallops, and calico scallops. Sea Scallops (Placopecten magellanicus): They are large scallops harvested in the Northeast U.S. and Canadian waters. They are also known as Alaskan scallops, Great scallops, Jumbo scallops, King scallops, and Diver scallops or Dayboat scallops. They measure up to 2 inches in diameter and have a texture that is chewier with a mild, sweet flavor. Bay Scallops (Argopecten irradians): These are smaller scallops harvested in waters from North Carolina to Massachusetts. They have a softer texture than sea scallops and have a ½-inch diameter. Weathervane Scallops (Patinopecten caurinus): These are harvested in Alaskan waters. You can distinguish weathervane scallops sexes based on their gonad color. While female gonads are orange to red, male gonads are creamy white. They are low in fat and high in protein. Calico Scallops (Argopecten gibbus): They are medium-sized edible marine scallops harvested in waters from North Carolina and Florida. They are also known as the Atlantic calico scallops and grow up to three inches wide. The shell near the hinge is extended into their ears. Japanese Scallops (Patinopecten yessoensis): They are also known as Yesso scallops and are harvested in Japan. Their weight ranges from 9 lbs. to 28 lbs. They are rich in minerals and very creamy. Also, they are the sweetest among all scallops. Icelandic Scallops (Chalmys islandica): These bivalve mollusks are harvested in Europe, Iceland, and Canada. They have a hard surface just like a rock. The Icelandic scallops can reach up to 14 cm and their color is highly variable. Pink Scallops (Chlamys rubida): These are much smaller than the other varieties that are commercially available. These small scallops are harvested in waters from Alaska to California. Spiny Scallops (Chalmys hastata): These scallops are also known as swimming scallops or spear scallops. They are harvested on the west coast of Canada and have a deeper, more complex flavor. They taste like the ocean! Scallops contain high protein and are loaded with essential nutrients.

Health Benefits Of Scallops

1. May Help With Weight Loss

According to the American Journal Of Clinical Nutrition, there is a link between your protein intake, satiety, and weight management (2). A study conducted by the University of Copenhagen, Denmark, on 1209 adults found that diets rich in protein help with weight loss (3). Incorporating seafood as a part of a nutritionally balanced energy-restricted diet helps boost weight loss (4). In addition, the fewer calories and higher protein content of scallops help prevent excess fat and maintain lean body mass (5).

2. Promote Heart Health

Dietary intake of cod and scallops may help reduce atherosclerotic (build-up of fats in artery walls) plaque (6). Scallops are low in saturated fat and their daily intake helps decrease the risk of cardiovascular disease (7). In addition, the potassium and magnesium in scallops help treat hypertension (8). Several studies have shown that magnesium deficiency is linked with heart problems (9), (10).

3. Help Improve Nervous System Function

Animal studies conclude that administration of plasmalogens, which are derived from scallops, helps improve cognitive function in people with mild Alzheimer’s disease and cognitive impairment (11). Also, the presence of B vitamins (like vitamin B12) in scallops helps lower homocysteine and improve brain health (high homocysteine levels are linked with cognitive impairment) (12), (13). In addition, seafood is high in omega-3 fats that help improve brain function (14).

4. Help Strengthen Bones

The protein scallops may help reduce hip fracture risks and improve bone health. A review published in the Computational and Structural Biotechnology Journal suggests that high protein intake plays a key role in maintaining bone mineral density (BMD) in older adults (15). However, more studies are warranted to understand this phenomenon of scallops.

5. Support A Healthy Pregnancy

A study published in the American College of Obstetricians and Gynecologists suggests that an intake of 2 to 3 servings of seafood per week helps support healthy pregnancy (16). These are the important benefits of scallops. However, do not consume them in excess amounts. Consuming anything in excess may cause undesirable effects, and so is the case with scallops.

Possible Side Effects Of Scallops

Intake of scallops in moderation is generally considered safe. However, some people may experience allergic reactions to shellfish, including scallops. Tropomyosin is the major allergen found in scallops, shrimps, and crabs (17), (18). The symptoms of shellfish allergy include hives, trouble swallowing, shortness of breath, dizziness, confusion, pale skin, indigestion, diarrhea, and vomiting. In some cases, people may experience anaphylactic shock. In addition, scallops may accumulate heavy metals such as mercury, arsenic, lead, and cadmium. Their accumulation in the body may lead to memory issues, kidney damage, and depression (19). Note: People watching their sodium intake should check the amount of salt added in the preparation of scallop recipes. You should store scallops carefully to avoid damage.

How To Store Scallops?

Keep your scallops in the refrigerator if you want to eat them within two days. You can also freeze them in the freezer where they can last up to three months. Avoid buying scallops with broken shells and without any labels on the product packages. Note: If you buy frozen scallops without the shells, make sure the package is not damaged.

How To Prepare Scallops?

 Place an oyster shucking knife at the hinge and prize it open slightly.  Turn the scallop over and run a flexible fish filleting knife over the flat side of the shell to release the scallop.  Open the shell fully. Use a spoon to release the scallop from the bottom shell.  Discard the frill, the black stomach sack, and any other pieces that are around the meat of the scallop. You would be left with just the white flesh.  Rinse the scallop thoroughly in cold water.

Conclusion

Are scallops really stingray? No. Scallops are not stingrays. However, in the seafood industry, people are often duped into eating ‘fake scallops’ made from stingray, shark, or skate meat, instead of scallops. There is a way to tell if a scallop is real. They have a slightly different shape instead of a cylinder and are not perfectly round. Why do scallops smell so fishy? Scallops generally do not have any odor. A fishy smell indicates that they are not fresh and you should discard them. Are scallops better than salmon? No. Salmon is a better source of protein and beneficial omega fatty acids than scallops (20).
