Sushi crab meat, a staple in many sushi restaurants, has long been a topic of interest among seafood enthusiasts and health-conscious individuals alike. While it may seem like a straightforward ingredient, the truth behind sushi crab meat is more complex than meets the eye. In this article, we will delve into the world of sushi crab meat, exploring its composition, production process, and the various types of crab meat used in sushi.
What is Sushi Crab Meat?
Sushi crab meat, also known as “surimi” or “kanikama,” is a processed seafood product made from fish proteins, starches, and other ingredients. It is designed to mimic the taste, texture, and appearance of real crab meat, making it a popular choice for sushi restaurants and seafood markets.
The Composition of Sushi Crab Meat
Sushi crab meat is typically made from a combination of the following ingredients:
- Fish proteins (such as pollock, whitefish, or other whitefish species)
- Starches (such as potato, tapioca, or wheat)
- Sugar
- Salt
- Vegetable oils
- Egg whites
- Flavorings (such as crab extract or other seasonings)
- Colorings (such as paprika or other natural dyes)
These ingredients are mixed together and then formed into flakes, chunks, or other shapes to resemble real crab meat.
The Role of Fish Proteins in Sushi Crab Meat
Fish proteins are the primary component of sushi crab meat, accounting for up to 50% of its composition. The most commonly used fish proteins come from pollock, a mild-flavored whitefish species found in the North Pacific Ocean. Other whitefish species, such as cod or haddock, may also be used.
The fish proteins are typically extracted from the fish using a process called “surimi processing.” This involves grinding the fish into a fine paste, removing the bones and skin, and then washing the paste to remove impurities. The resulting protein-rich paste is then mixed with other ingredients to create the final product.
The Production Process of Sushi Crab Meat
The production process of sushi crab meat involves several steps:
- Fish selection and processing: Fish are selected based on their freshness and quality, and then processed into a fine paste using the surimi processing method.
- Mixing with ingredients: The fish paste is then mixed with other ingredients, such as starches, sugar, salt, and flavorings, to create a uniform blend.
- Forming and shaping: The mixture is then formed into flakes, chunks, or other shapes to resemble real crab meat.
- Cooking and pasteurization: The formed crab meat is then cooked and pasteurized to kill any bacteria and extend its shelf life.
- Packaging and distribution: The final product is then packaged and distributed to sushi restaurants and seafood markets.
Types of Crab Meat Used in Sushi
While sushi crab meat is a popular choice for sushi restaurants, there are other types of crab meat that may be used in sushi. These include:
- Real crab meat: Some high-end sushi restaurants may use real crab meat, such as king crab or snow crab, in their sushi dishes.
- Imitation crab meat: Imitation crab meat, also known as “surimi,” is a processed seafood product made from fish proteins and other ingredients. It is designed to mimic the taste and texture of real crab meat.
- Crab stick: Crab stick is a type of processed seafood product made from fish proteins and other ingredients. It is designed to resemble real crab meat and is often used in sushi rolls and other seafood dishes.
Comparison of Real and Imitation Crab Meat
| | Real Crab Meat | Imitation Crab Meat |
| — | — | — |
| Taste | Rich, sweet, and succulent | Mild, slightly sweet, and neutral |
| Texture | Firm, flaky, and tender | Soft, chewy, and slightly firm |
| Appearance | White or pinkish-white color | White or pinkish-white color |
| Price | Generally more expensive | Generally less expensive |
| Shelf life | Shorter shelf life due to perishable nature | Longer shelf life due to processing and preservatives |
Health and Safety Concerns
While sushi crab meat is generally considered safe to eat, there are some health and safety concerns to be aware of:
- Food allergies: Some people may be allergic to fish or shellfish, which can cause an allergic reaction when consuming sushi crab meat.
- Mercury content: Some fish species used in sushi crab meat, such as pollock, may contain high levels of mercury, which can be toxic to humans in large quantities.
- Preservatives and additives: Some sushi crab meat products may contain preservatives and additives, such as sodium benzoate or MSG, which can be detrimental to human health in large quantities.
Choosing a Safe and Healthy Sushi Crab Meat
To choose a safe and healthy sushi crab meat, look for products that are:
- Made from sustainable and responsibly sourced fish
- Low in mercury and other toxins
- Free from preservatives and additives
- Processed and handled safely to prevent contamination

What is sushi crab meat, and how is it made?
Sushi crab meat, also known as surimi, is a type of processed seafood product that mimics the taste and texture of real crab meat. It is typically made from a combination of fish proteins, such as pollock or whitefish, which are pulverized and then reformed into a crab-like texture. The mixture is then flavored and colored to resemble real crab meat.
The manufacturing process of sushi crab meat involves several steps, including grinding, mixing, and shaping. The fish proteins are first ground into a fine paste, which is then mixed with other ingredients such as starch, sugar, and salt. The mixture is then shaped into flakes or chunks, depending on the desired texture, and finally, it is cooked and packaged for distribution.
What are the benefits of using sushi crab meat in sushi rolls?
One of the main benefits of using sushi crab meat is its affordability compared to real crab meat. Sushi crab meat is generally cheaper to produce and purchase, making it a more accessible option for sushi restaurants and consumers. Additionally, sushi crab meat has a longer shelf life than real crab meat, which makes it easier to store and transport.

Another way to tell is to check the ingredient list or ask your server. If the ingredient list includes words like “surimi” or “imitation crab meat,” it’s likely that you’re eating sushi crab meat.
