Crab sticks: no crabs were harmed — benefits and risks, ingredients

13

Crab sticks are a popular imitation of crab meat made from surimi (fish paste). The fake crab is and the body digests it quickly. But it also has contraindications and composition red flags: aim for products with natural ingredients. Why don’t crab sticks contain any crab, and what does a high-quality imitation of crab meat look like?

“Washed” fish paste: what crab sticks are actually made of

By shape and color, the imitation product resembles the meat of a crab claw, but that impression is misleading. If you look closely at what crab sticks are actually made of, you’ll find that they don’t contain crab meat at all despite the name, although they do include processed fish protein. In the best-case scenario, the edible product is made from ground white fish fillet or surimi. Surimi literally means “washed chopped fish” in Japanese. The Japanese company Sugiyo introduced the culinary novelty called Kanikama in 1973. But the raw material itself wasn’t a technological breakthrough — the Japanese have been “washing” fish paste for almost a thousand years.
An archaic recipe for washed chopped fish similar to modern surimi was known in Japan long before 1115. By the 14th century, dishes made from washed paste of white cod-family fish were already commonly prepared across the Land of the Rising Sun. The exact origin of the popular fisherfolk dish remains unclear. Thinking about the circumstances under which surimi was first created, it’s reasonable to assume that people sometimes had to wash the ground fish mass many times in fresh water and then squeeze it well — for example, to salvage accidentally soiled raw material. In the end, that “washed” paste produced culinary items with unexpectedly pleasant flavors.

An optical illusion: why crab sticks contain no crab

Those early surimi balls differed from ordinary fish cutlets by their unusual whiteness, firm, even texture, and absence of fishy oil smell. The lack of that odor proved especially valuable to the Japanese because fish was one of their primary protein sources. Surimi took on a role in local cuisine almost as important as rice: both products let cooks vary flavor using spices or vegetable add-ins. Steamed surimi sausages took local names like “kamaboko” and “narutomaki.” Japan even celebrates a kamaboko festival every November 15.
A barrier to mass industrial production of surimi products was the short shelf life of prepared paste, since freezing it destroyed refined protein structures and formed ice crystals. Manufacturers solved that problem in 1959–1960 when they developed an “edible antifreeze” made from the low-molecular-weight sugar sucrose combined with the six-carbon alcohol sorbitol. Those components helped the fish mixture’s taste approximate crab meat. In the first crab sticks released in 1973, the maker Sugiyo even used an extruder to mimic crab muscle fibers, which strengthened the illusion of authenticity.

The “artificial crab”

Three years later, the product that now makes up about 10% of all kamaboko consumption in modern Japan was introduced to the international market. Culinary experts quickly embraced it, calling the crab flavor of surimi rolls quite harmonious. The resemblance of the “artificial crab” to pricey real crab meat gave concentrated, deodorized fish protein strong export potential and opened the door for crab sticks to go global. Different countries developed their own production methods and adjusted the recipe and component ratios as they saw fit. Since 1993, manufacturers have labeled the imitation product as “crab sticks, flavored.”
Producers flavor white-fish paste to mimic crab meat. Such products can contain flavor enhancers (notably monosodium glutamate), colorants (for example, E171, E160), and stabilizers, which makes them less diet-friendly than expected. Because of , surimi-based fish products should be consumed with caution. Despite a protein base, tender texture, and pleasant mildly sweet taste, crab sticks — a convenient ingredient for quick dishes (used in salads, sauces, and appetizers) — shouldn’t be treated as everyday food. When buying, pay attention to the ingredient list because some products replace surimi with soy and egg protein, starch, and flavored additives.

How to choose crab sticks

A quality product has an even color, a smooth surface without cracks, and contains at least 40% surimi — ground fillet of (pollock, haddock, or hake) from the northern Pacific. Premium crab sticks use binding ingredients like egg and starch (sometimes flour), natural colorants (for example, paprika or carmine from cochineal), and flavor extracted from lower-grade parts of crustaceans. In other cases, manufacturers use nature-identical flavor enhancers, aromatic blends, colorants, and thickeners. Prefer ingredients of natural origin whenever possible.
Avoid buying the product sold loose by weight, because in that case you won’t have complete information about ingredients or the manufacturer. Quality crab sticks come in factory packaging. The ingredient list should show mostly natural components.
To determine a crab stick’s composition, read the label:

1. surimi (fish paste) — not soy or starch;
2. natural vegetable oil;
3. chicken egg protein;
4. table salt;
5. a little sugar and starch.

How do you read the composition if the manufacturer doesn’t state the amount of fish paste? Then check how much protein is in 100 g on the package — if protein is high, the fish content is high.

Are crab sticks harmful or not?

When made to quality standards, the “artificial crab” is a perfectly useful and even diet-friendly high-protein product. Crab sticks have these characteristics:

• rectangular oblong shape, a faint seafood smell, slightly salty taste, and a “rubbery” texture;
• layers can be pulled apart, unwinding like string cheese;
• color: pink on one side and white on the other; very bright red coloring can indicate the use of artificial dyes;
• inside — white with a uniform structure and soft consistency;
• they should not be oversaturated with water; do not freeze them to avoid losing moisture.

The benefits and harms of crab sticks are balanced by price. Crab sticks are a source of protein, an inexpensive substitute for real crab meat, and a cheap source of fish protein. In contrast, soy protein in the product can worsen chronic liver and kidney conditions.
Crab sticks have these contraindications:

• gastritis;
• ;
• ;
• individual intolerance;
• pregnancy and breastfeeding;
• children under three years old.

If there are no reasons for contraindications, the product hasn’t been exposed to harmful conditions, it was stored properly, the vacuum package is intact with a current production/sale date, and it was sold in a reputable store with reliable refrigeration, you shouldn’t expect harm from crab sticks made with natural ingredients.

Macros in crab sticks

Calories, protein, fat, and carbs (macros) are a way to track a product’s or a diet’s nutritional value. The of crab sticks: protein — 6–8 g; fat — 0.4–1.5 g; carbohydrates — 10–15 g (depending on starch and sugar content). Calories in 100 g of crab sticks are about 73–95 kcal (values vary by manufacturer). The low fat content makes crab sticks a diet-friendly choice: this low-calorie product consists mainly of fish protein. And although crab sticks typically contain more carbohydrates than protein, the “artificial crab” can be consumed as a diet food that the body digests quickly. Crab sticks are .
Low calorie content helps create the energy deficit needed for weight loss. But consult a doctor before starting any diet to avoid unwanted consequences and mistakes in building your menu. When using crab sticks for weight loss, consider that the calorie count of a salad with mayonnaise is much higher — about 142 kcal per 100 g. Because crab sticks often contain preservatives and flavor enhancers (monosodium glutamate), they add little nutritional value and can cause water retention. Eat crab sticks in small portions, preferably paired with vegetables. Moderate consumption of the “artificial crab” won’t pose a threat, but it won’t replace real crab.
