Imitation crab meat, sometimes called surimi, is a popular ingredient found in many seafood dishes and sushi rolls With its flaky white texture and mild crab flavor, this fishy imposter fools many unsuspecting diners. But what exactly is imitation crab meat made of and how does it get manufactured? In this comprehensive guide, I’ll unravel the mysteries of this phony shellfish and explain the step-by-step production process.
The Origins of Imitation Crab
Imitation crab meat was first created in the 1970s by Japanese food scientists trying to find an inexpensive alternative to expensive real crab Using a technique called surimi, they took ordinary white fish and transformed it into a clever crab substitute.
Surimi refers to fish that has been pulverized into a paste and then mixed with additives like salt, egg whites, and crab flavoring. This innovative product allowed consumers to enjoy the taste of luxurious crab without paying premium prices. Imitation crab meat surged in popularity across Japan, America, and beyond.
What Fish is Used to Make Imitation Crab?
The key ingredient in imitation crab meat is surimi a fish paste usually made from Alaska pollock. Sometimes other mild white fish like cod, hake or tilapia may also be used. These types of fish have a light flavor and white color that lends itself well to imitating real crab when processed.
Alaska pollock in particular thrives in the cold northern Pacific waters near Alaska. Large fleets of industrial fishing vessels harvest millions of pounds per year. The fish is highly abundant, inexpensive, and ideal for surimi manufacturing thanks to its snow-white flesh and lack of fishy taste.
Step-by-Step: How Imitation Crab is Produced
Imitation crab undergoes an extensive multi-step mechanical process to transform fish into faux crabmeat. Here is how it is mass-produced:
1. Catching & Cleaning the Fish
Fishermen haul in pollock and other whitefish in bulk. Back on land, workers remove the head, organs, bones, and skin, leaving behind dressed fillets. This process maximizes the amount of usable meat.
2. Mincing the Fillets into a Paste
The fish fillets get minced up into a fine protein paste using powerful metal grinders. It liquefies the meat into a smooth slurry called surimi.
3. Mixing in Various Additives
In large mixing machines, ingredients like salt, sugar, white egg protein, and natural or artificial crab flavors get blended into the surimi paste. These additives help improve the texture and taste.
4. Pumping into Molds
Next, pumps force the surimi mixture into different shaped molds and trays. It is tightly packed to form strips, chunks, shreds, legs, and other crab-like textures.
5. Cooking & Freezing
The molded surimi is lightly steamed then rapidly frozen. Cooking helps set the fish proteins while freezing preserves and sets the final shape.
6. Adding Color & Flavor
The frozen imitation crab meat gets a bath in a flavored solution and orange dye. This helps enhance color and makes the bland fish taste more like real crab.
7. Packaging & Shipping
Finally, the frozen imitation crab meat products are packaged up into boxes and shipped out to grocery stores and restaurants. Consumers can enjoy the affordable crab-flavored seafood year round.
How Does it Compare to Real Crab?
While cleverly disguised, imitation crab meat differs from real crab in a few ways:
-
Less Nutritious – Imitation crab meat loses nutrients like healthy omega-3s during processing. Real crab has higher levels of protein and minerals.
-
More Additives – Imitation crab contains added flavorings, colorings, and stabilizers while real crab is a more pure, natural product.
-
Different Texture – The flaky texture of imitation crab is softer and smoother than real crab, which has more varied chunks of meat.
-
Lower Price – The main appeal of imitation crab is that it costs significantly less than genuine crab meat. It retails for around $2-4 per pound compared to $15-20 per pound for real crab.
So while it may look and taste similar, imitation crab meat lacks the high-quality nutrition and flavors of whole crab. But its low price point makes it an enticing stand-in for budget-friendly seafood dishes.
Is Imitation Crab Meat Safe to Eat?
Imitation crab is safe to eat and approved by food regulatory agencies. However, there are some health concerns to keep in mind:
-
It is high in sodium, with over 300mg per serving. This can raise blood pressure.
-
Some additives like carrageenan, MSG, and sulfites can cause reactions in sensitive individuals.
-
The high processing depletes natural nutrients found in whole fish and real crab.
Overall, imitation crab is likely fine in moderation as part of a balanced diet. But limiting intake and choosing products with fewer artificial additives is a healthier approach.
Common Applications for Imitation Crab Meat
Imitation crab meat finds its way into many seafood dishes:
- California rolls and sushi
- Seafood salads
- Crab cakes
- Dip appetizers like crab rangoons
- Surf and turf dishes
- Casserole bakes
- Crab soup and bisques
Its ability to mimic the taste of real crab makes it a money-saving substitution in recipes. Just keep in mind that the texture will be slightly different than whole crab meat.
How to Identify Imitation vs Real Crab
When enjoying your favorite crab recipes, how can you discern between imitation and real crab meat? Here are some tips:
-
Check the Label – Imitation crab will be labeled as “imitation crab meat” or “crab-flavored seafood”. Real crab is simply labeled as crab.
-
Look at the Price – Imitation crab costs significantly less than real crab. If the price seems too good to be true, it probably is imitation.
-
Examine the Color – Real crab meat is an off-white color while imitation crab has an unnaturally bright orangey-pink hue from dyes.
-
Read the Ingredients – Imitation crab contains a long list of extra ingredients while real crab meat contains only crab and water.
The Takeaway on Imitation Crab Meat
Imitation crab meat provides budget-friendly taste of crab using minced fish and clever flavoring. The manufacturing process finely grinds whitefish like pollock into a surimi paste mixed with additives that mimics real crab. While not as nutritious or natural as whole crab, imitation crab can be enjoyed in moderation as an affordable seafood option. Being able to identify and understand what you’re eating is key to making informed choices. So next time you enjoy a California roll, you’ll know exactly what that “crab” meat really is!
How Is Imitation Crab Different From Real Crab Meat?
You have probably eaten imitation crab meat without realizing it. Since it has become so popular, it has found its way to your plate through restaurant menus, appetizers at parties, and grocery store products. Packages with imitation crab may be labeled as “crab seafood” or “surimi seafood” so you know what youâre buying. On some restaurant menus, an item may be spelled as “krab” as a way to tell you that its not made with real crab meat.â
Nutritional value. Real crab has significantly higher nutrient levels than imitation crab. For example, imitation crab derives most of its calories from added carbs. The calories in an Alaskan king crab are derived from proteins, not from carbs. If youâre on a keto or low-carb diet and are trying to cut your carb intake, real crab would be the better choice.
Vitamins and minerals. Real crab provides a higher amount of vitamins and minerals. Itâs a good source of vitamin B12, selenium, and zinc. When making surimi, these nutrients are lost during washing and processing when the fish meat is exposed to heat. Real crab also has a higher amount of omega-3 fatty acids than its mock substitute. Some packages of imitation crab may have added omega-3, but this isnât always the case.
Imitation crab contains several processed ingredients. The largest component of the imitation crab product is surimi. It contributes 35% to 50% of the productâs weight. The other 50% to 65% that makes up imitation crab contains:
- Starches like wheat, potato, or tapioca starch make the surimi firm and freezable.Â
- Salt (sodium chloride) adds flavor and helps turn the minced meat into a sturdy gel. Sometimes, potassium chloride is used.
- Vegetable oil enhances texture, shelf life, and white coloring.
- Sugar and sorbitol add some sweetness and help imitation crab to freeze and thaw with ease.
- Egg whites or soy are often added for a boost of protein and to improve texture, color, and glossiness.
- Water takes up the biggest percentage of all the extra ingredients. It helps create the right texture.Â
How Is Imitation Crab Made?
Imitation crab is made with surimi, a paste made out of finely shredded or pulverized fish. After the fish is minced, it is heated and pressed into shapes that resemble meat from a crab leg. The resulting imitation crab looks similar to the original crab in its coloring and texture.
Binding agents, like egg white, starch, vegetable oil, or sugar, are added to the surimi paste to make the meat stick together. Occasionally, monosodium glutamate (MSG) is added to the surimi. Orange or red coloring is the key ingredient added to make the mixture resemble shellfish meat. For the preservation of the product, the makers vacuum seal and pasteurize the imitation crab meat. When you buy the product, you will eat it straight from the package.
