Crab sticks, also known as seafood sticks or imitation crab meat, have become a ubiquitous ingredient gracing sushi rolls, salads, and snack platters around the world. But despite their widespread popularity, few people truly understand how these tantalizing sticks are actually manufactured. In this comprehensive guide, we’ll peel back the curtain and take an illuminating dive into the fascinating production process behind crab sticks.
A Primer on Crab Sticks
Before examining the intricacies of crab stick-making, let’s first build a foundation of what exactly crab sticks are.
-
Crab sticks consist of minced white fish combined with starch, egg whites, flavorings, and colorings to resemble the taste, texture, and appearance of real crab meat.
-
The most common types of fish used are Alaska pollock, Pacific whiting, and cod No actual crab goes into crab sticks
-
Crab sticks belong to a category of seafood products known as surimi, a Japanese term for processed fish paste.
Now that we’ve established the basic facts about crab sticks, let’s jump into seeing how they’re crafted!
Behind the Scenes: Inside Crab Stick Factories
Crab sticks emerge from highly mechanized factories designed for efficient mass production. Here are the main stages:
Washing and Mincing the Raw Fish
-
Production starts with fresh fish delivered to the plant. The fish is fed into large washers to remove impurities.
-
Next, specialized mincing machines grind the fish into a smooth, fine paste. This exposes fish proteins and creates a uniform texture.
Mixing in Binders and Flavorings
-
The fish paste is pumped into enormous mixing machines. Here, workers add binders like starch and egg whites along with seasonings, crab flavor, coloring, sugar, and salt.
-
These additives bind the proteins, lend signature crab taste, and develop the unique bouncy bite of crab sticks.
Kneading, Molding, and Cutting the Mixture
-
A kneader aligns the fish and additive mixture into a unified paste with a sticky, stretchable consistency.
-
The crab stick paste travels through extruders that push it out into long connected rods. Vibrating belts beneath slice the rods into individual sticks.
Cooking and Cooling
-
Conveyors transport the raw crab sticks into steam ovens for precise cooking. This firms up the texture and finalizes the flavor.
-
For food safety, blast chillers rapidly cool the cooked sticks before workers package them for distribution.
Ensuring Quality Control and Safety
Throughout processing, crab sticks undergo rigorous oversight:
-
Fish and ingredients are analyzed upon receipt
-
Computers monitor cooking conditions
-
Finished products are tested for moisture
-
Regular safety and sanitation protocols keep the process hygienic
By understanding the carefully controlled production process, we gain insight into how these imitation crab snacks achieve such consistent taste and quality.
A Remarkable Innovation in Seafood Technology
The manufacture of crab sticks represents an impressive evolution in food technology. Some key milestones include:
-
Adapting traditional Japanese surimi into a product for Western consumers
-
Employing advanced mechanization for large-scale production
-
Innovating artificial flavors that closely mimic real crab
-
Offering an affordable, convenient source of crab flavor to a mass market
Regardless of one’s opinions on imitation versus natural ingredients, the engineering brilliance behind crab stick production is undeniable.
The Ongoing Debate Over Authenticity
The advent of crab sticks has sparked debate around the integrity of seafood versus processed adaptations. Some perspectives to consider:
-
Purists argue against diluting traditional cuisine with lab-engineered ingredients.
-
Pragmatists appreciate crab sticks for their accessibility and convenience.
-
Innovators see crab sticks as inspiring creative applications of technology.
-
Traditionalists view imitation seafood as threatening culinary heritage.
The dialogue around authenticity is sure to continue as consumer awareness grows. But by shedding light on how crab sticks are made, we now have a clearer context for these discussions.
Satisfying a Craving with Science

Whether viewed as a marvel of industry or nutritional villain, understanding the technical process of crafting these imitation crab products gives new insight into the snacks many of us mindlessly consume. Next time you enjoy a piece of crab stick, appreciate the remarkable mechanics that went into satisfying your craving!
Comparison to Crab Meat
Real crab meat is much richer in protein compared to crab sticks. It also tends to have fewer calories since it contains no carbohydrates, unlike crab sticks, which are high in sugars and starch.
Real crab meat is low in fats but still contains more than crab sticks; therefore, it has a higher cholesterol level. However, the predominant fats found in crab meat are polyunsaturated fats with a high concentration of omega-3 fatty acids.
Compared to crab sticks, crab meat contains vitamins A, C, and B5. It is also higher in vitamins B12, B2, B3, B6, and E. However, crab sticks contain higher levels of vitamin B1 and vitamin K.
Real crab meat is richer in iron, calcium, potassium, copper, and zinc, whereas crab sticks are higher in magnesium and phosphorus. The sodium concentration is lower in imitation crabs.
Many seafood products cause significant environmental damage as some sea creatures are overfished and endangered due to high demand.
While Alaska pollock is not at risk of endangerment, surimi made from Alaska pollock has been researched to have a high carbon footprint due to the energy used to produce products such as crab sticks (20).
Other environmental issues that arise during surimi processing include the high use of water. The minced meat used to make surimi is washed multiple times. This requires much freshwater while creating more wastewater (21).
However, surimi production can also have a beneficial impact on the environment. As surimi is made from minced meat, it provides an opportunity to use various ingredients as its source of protein, including the underutilized species with little or no commercial value. This could be a way of using abundant resources that would otherwise have been neglected (21).

FAQ
How do they make crab sticks?
How unhealthy are crab sticks?
However, crab sticks are a highly processed food with a high content of salt, starch, and sugars; therefore, they should be used with caution. Real crab meat, although higher in fats, is a better option for healthy weight loss diets, as it is richer in beneficial nutrients and contains no carbohydrates.
Where did crab sticks come from?
Most crab sticks today are made from Alaska pollock (Gadus chalcogrammus) of the North Pacific Ocean.
How do they make crab extract?
The crabs are mashed into a paste with salt. The paste is mixed with water so the gooey meat dissolved into the water. That mixture is strained off to remove the pieces of shell. The strained water is then cooked until the meat separates out into a cake on the top.
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.
How do you cook crab sticks?
To solidify the shape, the crab sticks are cooked in boiling water or steam. This cooking process also enhances the flavor and improves the texture of the final product. Once cooked, the sticks are cooled rapidly to prevent any bacterial growth and maintain their firmness.
Do crab sticks contain crab meat?
No, crab sticks do not contain actual crab meat. They are made from a mixture of white fish meat and various additives. 2. What type of fish is used to make crab sticks? Different types of fish can be used, but commonly, Alaskan pollock or Pacific whiting are used due to their mild flavor and availability. 3. Are crab sticks safe to consume?
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.
Are crab sticks real?
