1. Defining Imitation Crab: What Is It?
Imitation crab, also referred to as surimi seafood or “krab” (a common spelling to indicate it isn’t real crab), is a processed food product designed to mimic the flavor and texture of real crab meat. It is often used in dishes like California rolls, crab cakes, and seafood salads as a more affordable alternative to genuine crab. But what exactly goes into this widely consumed seafood substitute?
2. The Primary Ingredient: Surimi
2.1 Understanding Surimi
Surimi is the base ingredient for imitation crab. It’s a paste made from fish that has been deboned, washed, and minced. The most common type of fish used to make surimi is Alaska pollock, a mild-flavored white fish. Other fish species that can be used include Pacific whiting, cod, and other white-fleshed fish.
2.2 The Surimi Production Process
The production of surimi involves several key steps:
- Deboning and Mincing: The fish is first deboned and then minced to create a fine pulp.
- Washing: The minced fish is washed multiple times to remove fat, blood, and other unwanted components. This washing process helps to create a bland, odorless base.
- Straining: The washed fish pulp is strained to remove excess water and any remaining solid particles.
- Mixing: The strained surimi is mixed with cryoprotectants (such as sugar and sorbitol) to prevent it from deteriorating during freezing.
2.3 The Role of Surimi in Imitation Crab
Surimi typically makes up about 35% to 50% of the final imitation crab product. It provides the basic structure and texture that mimics the flakiness of real crab meat.
3. Additional Ingredients in Imitation Crab
Besides surimi, imitation crab contains a variety of other ingredients that contribute to its flavor, texture, and appearance. These additives are essential in transforming the bland surimi paste into a product that closely resembles real crab meat.
3.1 Binders and Stabilizers
3.1.1 Starches
Starches are added to surimi to improve its texture and freeze-thaw stability. Common starches used in imitation crab include:
- Wheat Starch: Provides firmness and structure.
- Potato Starch: Enhances the moisture retention and texture.
- Tapioca Starch: Contributes to the gel-like consistency.
These starches help the surimi maintain its shape and prevent it from becoming too mushy or watery during processing and storage.
3.1.2 Egg White or Soy Protein
Egg white or soy protein are often added to increase the protein content and improve the texture and color of the imitation crab. These ingredients act as binders, helping to hold the surimi and other components together.
3.2 Flavor Enhancers
3.2.1 Salt (Sodium Chloride)
Salt is a crucial ingredient in imitation crab, serving multiple purposes:
- Flavor: Enhances the overall taste.
- Texture: Helps to create a firm gel-like texture.

Potassium chloride is sometimes used as a substitute for sodium chloride to reduce the sodium content.
3.2.2 Sugar and Sorbitol
Sugar and sorbitol are added to provide sweetness and help the imitation crab withstand freezing and thawing without losing its texture. Sorbitol also acts as a humectant, retaining moisture in the product.
3.2.3 Monosodium Glutamate (MSG)
MSG is a common flavor enhancer that intensifies the savory taste of the imitation crab, making it more palatable and similar to real crab meat.
3.3 Colorings
3.3.1 Artificial Colors
Artificial colors are used to give imitation crab its characteristic reddish-orange hue, mimicking the appearance of real crab legs. Common artificial colors include:
- Carmine: A natural red dye derived from insects.
- Paprika Oleoresin: An extract from paprika peppers, providing a natural orange-red color.
These colorings are essential in making the imitation crab visually appealing and recognizable to consumers.
3.4 Texturizers
3.4.1 Vegetable Oil
Vegetable oil, such as soybean oil or canola oil, is added to improve the texture, shelf life, and color of the imitation crab. It helps to create a smoother, more palatable product.
3.4.2 Water
Water is a significant component of imitation crab, helping to create the right texture and consistency. It is added to the surimi mixture to achieve the desired moisture level.
4. Nutritional Composition of Imitation Crab
