Crab sticks, also known by names like krab, seafood sticks, or imitation crab meat, are a popular product that can be found in grocery stores and restaurants around the world Their sweet flavor, meaty texture, and versatility have made them a staple ingredient in various cuisines But despite their widespread use, few people know exactly how these intriguing sticks are manufactured.
In this article, we’ll peel back the curtain and take an in-depth look at the fascinating process of how crab sticks are made. We’ll explore the ingredients, equipment, and step-by-step production methods that allow factories to churn out these imitation crab products by the truckload.
Overview of Crab Sticks
Before diving into the production process, let’s start with a quick overview of what crab sticks actually are.
Crab sticks are made from minced white fish flesh combined with additives like starch, egg whites, flavorings, and colorings. The resulting mixture is shaped into sticks that are designed to resemble crab meat.
Despite the name, crab sticks contain no actual crab. They are a type of surimi, the Japanese term for processed fish products. The most common types of fish used are Alaska pollock, Pacific whiting, and various cod species.
Now let’s take a look behind the scenes!
The Crab Stick Production Process
Crab sticks are produced in large factories utilizing an efficient mechanized process. Here are the main stages:
Washing and Mincing the Fish
Production starts with tons of fish delivered fresh to the factory. Workers feed the fish into large mechanical washers to remove impurities.
The fish then pass through specialized mincing machines which finely chop the meat into a paste. This creates a smooth texture and exposes fish proteins.
Mixing in Additives
Next, the minced fish paste travels to the mixing machines. Here, workers add ingredients like starch, egg whites, sugar, salt, flavoring, and coloring.
Starch binds the proteins in the fish to create a bouncy, meat-like texture. Egg whites also help bind and add cohesion.
Kneading and Forming
The fish and additive mixture passes through a kneader which aligns the sticky proteins through mechanical action. This develops the unique chewy, stretchy texture of crab sticks.
The resulting surimi paste travels through extruding machines which push out and form long connected sticks. Vibrating belts below cut the sticks into equal segments.
Cooking
The raw crab stick pieces are transported by conveyor belt into continuous steam ovens. The sticks cook under pressure in the moist heat.
Cooking times and temperatures are precisely controlled. This firms up the texture, kills bacteria, and finalizes the crab stick flavor.
Cooling and Packaging
After cooking, the crab sticks pass through blast chillers which rapidly cool them down for food safety and to preserve the texture.
Finally, workers package the cooled crab sticks into boxes or bags for distribution. Automated scales ensure consistent weights.
Behind the Scenes of a Crab Stick Factory
To better visualize the process, let’s imagine walking through a crab stick factory:
The air is filled with a distinct briny aroma as workers feed ice-cold fish into rumbling washers. Clouds of steam billow out from cooking ovens. Machines hum as they churn out endless streams of perfectly formed crab stick pieces.
In mixing rooms, white-coated technicians fine-tune recipes, carefully calibrating flavors and textures. Conveyors snake overhead, shuttling materials smoothly between processing stages.
Quality control personnel dot the lines, scrutinizing products for consistency of size, color, and taste. Workers deftly pack the finished sticks into boxes headed for grocery stores around the world.
Quality Control and Food Safety
Throughout processing, crab sticks undergo rigorous quality control checks:
-
Fish is tested for freshness and purity upon receipt
-
Computers monitor cooking times and temperatures
-
Finished products are probed for correct moisture levels
-
Random samples are regularly analyzed in labs
Thorough sanitation and employee training ensure food safety. Production facilities follow HAACP plans and are subject to regulatory inspections.
Final Thoughts
So there you have it! That’s a look inside how those intriguing crab stick snacks are made. An amazing mechanized process transforms fish into the final craveable product.
Next time you enjoy a piece of crab stick, you’ll appreciate the complex manufacturing that went into it. The state-of-the-art factories churning out these imitation crab snacks operate remarkably efficiently to supply demand worldwide.

How are crab sticks made?
The process of making crab sticks begins by mincing and washing the fish meat to remove any impurities and unwanted flavors. After that, the fish meat is mixed with starch and additives, such as salt and sugar, to enhance the taste and texture. Some manufacturers may also add seasonings like crab flavoring to further imitate the taste of real crab.
Do crab sticks contain crab meat?
While they are made to look like crab meat, most crab sticks do not contain any actual crab. That’s why they are often just called seafood sticks or imitation crab. The main ingredient of crab sticks is surimi – finely pulverised white fish – most commonly Alaska pollock.
What are crab sticks?
Crab sticks are pieces of imitation crab meat that have been pressed together into the shape of a stick, and often dyed to have a red color similar to a crab’s shell. This type of meat is often more affordable for use in seafood salads and similar dishes, and since it is cooked during its processing it can be eaten without further preparation.
How do crab sticks taste?
The crab taste is only in the flavouring. Essentially, crab sticks are made of concentrated whitefish protein. The fish meat is shredded, rinsed over and over in freshwater, then pressed until it turns into an odourless and tasteless paste. We call it “surimi base”. The base is frozen between -20 and -30°C, then sold to food companies.
