Pollock roe, also pollack roe (also known as tarako in Japanese and myeongnan in Korean), is the roe of Alaska pollock (Gadus chalcogrammus) which, despite its name, is a species of cod. Salted pollock roe is a popular culinary ingredient in Japanese, Korean and Russian cuisines.

Names

[edit]

The purely Korean name for pollock, myeongtae can be written with Hanja 明太 (명태), which can be read as mentai in Japanese. But while the Japanese borrowed this name from Korean and called it mentaiko,[1] the term does not retain the original meaning of plain raw roe, but specifically refers the chili pepper-added cured roe, while salt-cured only types are called tarako.[1][2][3]

Korean

[edit]

As aforementioned, Alaska pollock in Korean is myeongtae (Korean: 명태; Hanja: 明太), hence pollock roe is myeongnan (명란; 明卵), a contracted form of the compound with +ran or +nan (란; 卵) meaning "egg (roe)".

The salted roe dish is called myeongnan-jeot (명란젓), being considered a type of jeot (젓) or jeotgal, which is a category of salted seafood.

Japanese

[edit]

In Japanese, (salted) pollock roe is called tarako (鱈子),[2][3] though it literally means 'cod roe',[a] while true cod roe is distinguished by calling it hontarako.[4][5] The pollock roe, also known as momijiko, are usually salted and dyed red.[4][5][b]

Pollock roe cured with red chili pepper are 明太子 (mentaiko);[5][2] to put it another way, mentaiko refers to chili-laced versions of tarako, generally speaking,[1] even if not qualified as karashi-mentaiko with the prefix meaning 'chili'.[c]

Russian

[edit]

In Russian, pollock roe is called ikra mintaya (икра минтая). This name is also used to refer to salted roe. The Russian word ikra (икра) means "roe" and mintaya (минтая) is the singular genitive form of mintay (минтай), which means Alaska pollock. This word is derived from its Korean cognate, myeongtae (명태).

History

[edit]

Korea

[edit]

Koreans have been enjoying pollock roe since the Joseon era (1392–1897). One of the earliest mentions are from Diary of the Royal Secretariat, where a 1652 entry stated: "The management administration should be strictly interrogated for bringing in pollock roe instead of cod roe."[6] Recipe for salted pollock roe is found in a 19th-century cookbook, Siuijeonseo.

Japan

[edit]

A 1696 Japanese book records the use of Alaska pollock's roe in Hokurikudō.[7]

The dish mentaiko originates from Korea, but after years of modification, most of the pollock roe consumed in Japan is Japanese mentaiko.[8] [9] [10][11][12][13][14] Toshio Kawahara (川原 俊夫, Kawahara Toshio), who was born in the city of Busan, Korea during the Japanese occupation, founded the oldest mentaiko company in Japan called "Aji no Mentaiko Fukuya" (ja:ふくや) after World War II. He made several modifications to myeongnan-jeot to adapt to Japanese tastes and introduced it to Japan as "Karashi mentaiko" (ja:辛子明太子), its popular name is "mentaiko". The milder, less spicy version is called tarako (鱈子) in Japan.[8]

Traditionally, myeongnan-jeot was made before dongji (winter solstice). Intact skeins of Alaska pollock roe are washed carefully with salt water, then salted in a sokuri (bamboo basket). The ratio of salt to roe ranges from less than 5:100 to more than 15:100. After 2–3 days, salted and drained roe is marinated for at least a day with fine gochutgaru (chilli powder) and finely minced garlic. myeongnan-jeot is usually served with sesame seeds or some drops of sesame oil.

Myeongnan-jeot, whether raw, dried, and/or cooked, is a common banchan (side dish) and anju (food served with alcoholic beverages). It is also used in a variety of dishes, such as gyeran-jjim (steamed egg), bokkeum-bap (fried rice), and recently in Korean-style Italian pasta dishes.

Myeongnan-jeot is a specialty of South Hamgyong Province of North Korea, and Gangwon Province and Busan of South Korea.

[edit]

Mentaiko, adapted from Korean myeongnan-jeot,[9][10][11][12][13][14] hence the name mentai (derived from the Korean myeongtae, 명태, 明太, meaning pollack) + ko (Korean 알, 子, meaning baby/roe), is common in Japan. It is made in a variety of flavors and colors and is available at airports and main train stations. It is usually eaten with onigiri, but is also enjoyed by itself with sake. A common variety is spicy mentaiko (辛子明太子, karashi mentaiko). It is a product of the Hakata ward of Fukuoka City. Milder version is called tarako (鱈子),

Recently in Japan, mentaiko pasta has become common. Mentaiko is mixed with butter or mayonnaise and used as a sauce for spaghetti. Thin strips of nori (海苔) and shiso leaves are often sprinkled on top.

Pollack roe is dipped in a seasoning liquid. This method was invented in the grocery store "Fukuya(ふくや)" and became common in Japan.[15][16]

Mentaiko was nominated as Japan's number one side dish in the Japanese weekly magazine, Shūkan Bunshun.[17]

Tarako is served in a number of ways: plain (usually for breakfast),[18] as a filling for onigiri, and as a pasta sauce (usually with nori). Traditionally, tarako was dyed bright red, but recent concerns about the safety of food coloring have all but eliminated that custom.[18] In Kyūshū, tarako is commonly served with red chili pepper flakes.

Russia

[edit]

In Russia, pollock roe is consumed as a sandwich spread. The product, resembling liquid paste due to the small size of eggs and oil added, is sold as canned food.

As mentioned above, in Russian, the word for pollock roe is the same as for the caviar: "ikra". The same goes to a dish, known to the French as "caviar d'aubergine": "кабачковая икра", although it's a spread made of eggplants.

To make the pollock roe taste in a caviar-like way, one should make a butterbrot first e.g. to apply butter to the bread before adding the canned pollock roe. This will smoothen the excessive saltiness of the canned roe.

Pollock roe

View on Grokipedia
from Grokipedia
Pollock roe, also known as Alaska pollock roe, refers to the egg clusters or skeins produced by female Alaska pollock (Gadus chalcogrammus), a semipelagic gadoid fish abundant in the North Pacific Ocean, particularly in the Bering Sea and Gulf of Alaska. These roe are harvested as a valuable byproduct of the commercial pollock fishery, typically during the winter spawning season from mid-January to late April, and are prized for their mild, briny flavor and high nutritional value. In East Asian and Russian cuisines, pollock roe is a staple ingredient, often cured by salting and sometimes spiced with chili peppers or other seasonings to create specialties like Japanese mentaiko (spicy roe) or tarako (salted roe), and Korean myeongnan. The global production of pollock roe reaches approximately 50,000 metric tons annually (as of 2024), with Japan accounting for about 80% of consumption, underscoring its cultural and economic significance in the region. The Alaska pollock fishery, from which most roe is sourced, is the world's largest by volume and is certified sustainable by programs such as the Marine Stewardship Council and Alaska Responsible Fisheries Management, ensuring long-term viability through quotas and monitoring. Nutritionally, a 15-gram serving of cured pollock roe provides about 3.35 grams of protein (7% daily value), 351 milligrams of omega-3 fatty acids (including DHA and EPA for heart and brain health), approximately 4 milligrams of calcium (<1% DV), and 1.5 micrograms of vitamin B12 (63% DV), making it a nutrient-dense seafood option.

Biology and Sourcing

Source Species

Pollock roe is primarily derived from the Alaska pollock (Gadus chalcogrammus), a marine gadoid fish belonging to the cod family Gadidae. This species is native to the North Pacific Ocean, with key populations inhabiting the Bering Sea, Gulf of Alaska, and Sea of Okhotsk. The Alaska pollock features an elongated body that can reach up to 90 cm in length, characterized by a silvery coloration interrupted by dark spots along the back and sides. It exhibits schooling behavior in midwater depths, typically between 100 and 400 meters, and demonstrates a rapid growth rate, attaining sexual maturity within 3 to 5 years. While several species share the common name "pollock," such as the European pollock (Pollachius pollachius) found in the North Atlantic, the stands out as the dominant commercial source for due to its abundance and targeted fisheries in the Pacific. The 's is particularly valued for its quality and volume in these operations. Reproductively, spawns from to in deep offshore waters, with females producing large quantities of that can constitute up to 20% of their body weight. This seasonal event occurs in large aggregations, facilitating the species' high and population resilience. As a cornerstone of global fisheries, the supports the world's largest whitefish harvest, underscoring its ecological and economic significance.

Harvesting Methods

The primary commercial harvesting of pollock roe occurs through midwater in the , with major operations centered in and . In the United States, vessels tow large cone-shaped nets to capture schools of (Gadus chalcogrammus) at depths of 100-300 meters, primarily during the directed fishery seasons managed by the (NOAA). Russian fleets similarly employ trawl methods in the and adjacent areas like the , where quotas are set by federal authorities to align with stock assessments and prevent . International agreements, including those under the North Pacific Fishery Management Council, further regulate transboundary stocks to ensure sustainable yields across jurisdictions. Roe extraction takes place immediately after the catch on factory trawlers, where female fish are processed at sea to preserve quality. Workers remove the ovaries from the belly cavity, separating the roe sacs, which are then sorted by maturity stage, size, and visual integrity—premium grades like "mako" (fully mature, undamaged roe) are prioritized for export markets, particularly . This on-board handling minimizes degradation, with processing lines designed for efficiency on vessels up to 300 feet in length. Global production of , the key source for , exceeded approximately 3.4 million metric tons in 2024, with the yield typically ranging from 10-20% of the female body weight during peak spawning periods. Harvesting intensifies in winter ( to March), aligning with the "A-season" in the , when content is highest and contributes significantly to the fishery's value— alone accounted for nearly 20,000 metric tons in that year. For 2025, the total allowable catch (TAC) was increased by 6% to 1.38 million metric tons. Sustainability measures are integral to these operations, with both U.S. and Russian pollock fisheries holding (MSC) certification for effective management. NOAA enforces total allowable catches (TACs), such as the 1.3 million metric ton limit for the eastern in 2024, alongside bycatch reduction devices in trawl gear to protect like and . Seasonal closures and area-specific quotas further synchronize fishing with spawning cycles, supporting stock recovery and long-term viability.

Processing and Varieties

Traditional Methods

Following harvest from (Gadus chalcogrammus) fisheries, traditional processing of pollock roe emphasizes preservation through salting to extract moisture and enhance firmness while maintaining sac integrity. The roe sacs are initially covered with a dry salt mixture typically ranging from 12% to 25% NaCl concentration, with adjustments based on maturity—lower for roe (12%) and higher for overmature (18-25%)—for a duration of 4 to 10 hours. This salting process draws out excess moisture, firms the egg sacs to prevent bursting during handling. After salting, the roe is washed to remove excess salt and impurities, typically by rinsing for 10-20 seconds in running seawater, a 3% NaCl solution, or a dilute alum bath (0.1%) using a dip-and-drain method. This step preserves the delicate structure without over-softening the sacs. The washed roe is then air-dried or drained at controlled temperatures of 4-10°C for 1-3 days, often covered with polyethylene sheeting to minimize excessive surface drying while allowing gradual moisture loss that further stabilizes texture. For storage, traditionally processed pollock roe is vacuum-sealed in polyethylene containers or wrapped in plastic film and frozen at -28°C, achieving a shelf life of up to one year while retaining quality. Alternatively, refrigerated storage at 0-5°C extends usability to about 180 days for salted products. Quality grading of pollock roe focuses on sac integrity, color, and size to determine market value, with first-grade roe featuring undamaged sacs, uniform bright orange-red coloration, and larger egg sizes for optimal appearance and texture. Lower grades tolerate minor cuts, discoloration, or smaller sizes, often correlated with higher water content (58-75%). Larger sacs are preferred for their visual appeal and ease of processing.

Regional Variations

In , pollock is processed into mentaiko, a spicy where the intact roe sacs are first lightly salted and then marinated in a mixture of paste, , broth, and other seasonings to impart a bold, fiery flavor profile. This marination enhances the roe's natural briny taste with heat and , creating a versatile product often characterized by its vibrant orange hue from the chili. A variation known as karashi mentaiko emphasizes the spiciness through intensified chili incorporation, resulting in a more pungent and stimulating sensory experience compared to milder salted versions. Korean adaptations of pollock roe typically involve lighter salting to preserve a subtler, fresher oceanic flavor, followed by optional that develops mild tanginess over time. In some processes, the roe is fermented with additions like to balance saltiness with savory depth, yielding a product that is less aggressive than heavily cured counterparts. For extended preservation, heat treatment methods such as roasting are applied to low-salt variants, reducing microbial risks while maintaining texture and introducing subtle roasted notes. In , pollock roe is transformed into ikra through salting of loosened grains, which separates the eggs from their sacs for a loose, granular texture that facilitates spreading and mixing in dishes. This salting creates a robust, intensely savory profile, and optional imparts a smoky aroma, further distinguishing it from sac-intact preparations by emphasizing portability and bold preservation. Contemporary innovations in pollock roe processing focus on global export demands, incorporating and rapid freezing to extend while preserving quality for international markets. These methods often include minor enhancements like added sugar for balanced sweetness or (MSG) to amplify , adapting the product for diverse palates without altering core flavors. Such techniques have enabled significant exports, such as Russia's shipments of over 500 metric tons of frozen pollock roe to in 2025, supporting scalable distribution. In October 2025, Russia and signed an agreement to jointly promote pollock roe in the Chinese market.

Names and Terminology

Korean Terms

In Korean, pollock roe is commonly referred to as myeongran (명란), a term specifically denoting the roe of the ( chalcogrammus). This name combines "myeong" from myeongtae (명태), the Korean designation for , with "ran" (란; : 卵), meaning "egg" or "roe." The of "myeongtae" traces back to the 19th-century era, when a local in Myeongcheon-gun, , named the previously unnamed fish by blending "myeong" (from the district Myeongcheon) and "tae" (the surname of a who presented the catch). It is also directly called myeongtae-al (명태알), where "al" (알) explicitly translates to "egg" or "roe," emphasizing its biological origin. In product contexts, especially imports from fisheries, it is sometimes labeled as Alaska-al (알래스카 알) to highlight the species and sourcing, distinguishing it from other fish roes like those of or . For processed forms, the salted and fermented variety— a staple or —is known as myeongranjeot (명란젓), where "jeot" (젓) indicates salted typical of Korean seafood preserves. Soy-marinated versions, often seasoned with (soy sauce) for added , are termed ganjang myeongran (간장 명란), popular in modern preparations. These terms underscore pollock roe's role as a in , often featured in stews or rice dishes for its briny flavor.

Japanese Terms

In Japanese, pollock roe is primarily known as (たらこ), referring to the salted roe sacs harvested from ( chalcogrammus). The term tarako originates from "tara," the Japanese word for or codfish, combined with "ko," meaning child or eggs, literally translating to "cod's children" or "pollock eggs." This emphasizes the roe's status as the fish's reproductive product and has been used since at least the early 20th century in Japanese seafood processing. A popular variant is mentaiko (明太子), which denotes pollock roe cured with salt and marinated in chili peppers or other spices for a spicy flavor profile. The name mentaiko derives from "mentai," an adaptation of the Korean term myeongtae (명태) for , paired with "ko" for eggs; this reflects the ingredient's Korean roots before its adaptation in post-World War II. The 明太子 literally means "bright ," but the etymology prioritizes the phonetic borrowing from Korean rather than a direct royal reference. Pollock roe is graded based on the integrity of the sacs, with mako (真子) designating the premium quality featuring intact, mature, and unbroken ovarian sacs that preserve the roe's natural texture and appearance. Lower grades may include partially broken sacs, though specific terms like semi-mako are less standardized in commercial labeling and often fall under general tarako categories. These distinctions influence pricing and culinary suitability, with mako preferred for high-end presentations. Processed imitations of pollock roe, made from surimi (fish paste primarily from pollock), are labeled as surimi-roe or synthetic variants like plant-based tarako substitutes to mimic the texture and flavor affordably. Red-dyed versions of natural pollock roe, sometimes called momijiko (紅葉子) after the , enhance visual appeal but retain the core tarako designation. These terms highlight product-specific adaptations in Japanese markets, distinguishing authentic from engineered forms.

Russian Terms

In Russian, pollock roe is primarily referred to as ikra mintaya (икра минтая), which literally translates to " caviar" and is used in both trade and everyday contexts. This term specifically denotes the roe from (Gadus chalcogrammus), distinguishing it from other fish eggs. The etymology of ikra mintaya reflects its linguistic roots: "ikra" derives from the Proto-Slavic jьkrъ, meaning fish eggs or , a term shared across to describe unfertilized fish ova. "Mintaya" is the genitive singular form of "mintay" (минтай), the Russian common name for , which is a transliteration adapted from the species' scientific nomenclature Gadus chalcogrammus. Processed forms of pollock roe are commonly known as solenaya ikra (солёная икра), referring to salted roe that is often separated into loose grains for preservation and sale. This preparation method enhances shelf life while maintaining the roe's texture and flavor. In the , a key harvesting region, pollock roe is regionally termed ikra mintaya Alyaski (икра минтая Аляски) or informally "Alaska-ikra," highlighting its association with sourcing from the North Pacific. Salting remains a standard processing technique in this area to suit local trade preferences.

Historical Development

In Korean Culture

Pollock roe, known in Korean as myeongnanjeot (명란젓), has deep roots in Korean culinary history, dating back to the Dynasty (1392–1910). Historical records, including the Sillok (annals of the Dynasty), document its use as a served at the royal table, symbolizing the abundance of coastal fisheries and the nutritional value of marine resources in a society reliant on seasonal fishing. During this era, pollock roe was valued for its preservative qualities and flavor, often prepared as a salted or fermented that reflected the ingenuity of coastal communities in utilizing local species from eastern coastal areas. The modern popularization of pollock roe in Korea accelerated during the Japanese colonial period (1910–1945), particularly in , where Japanese fishing operations processed pollock and compensated Korean laborers with roe byproducts instead of cash wages. This practice led to increased availability and market presence, transforming it from a regional specialty into a more widespread preserved food. Following and the , a boom occurred in the with increased processing and availability supporting post-war recovery and establishing it as a symbol of resilient coastal abundance amid food scarcity. Imports of Alaskan pollock roe became significant from the 1980s onward as local catches began to decline due to warming waters. In the 21st century, Korean pollock catches have plummeted to near zero, heightening reliance on imports. In the 1970s, the Korean government promoted products, including roe, as an affordable protein source during periods of and resource challenges, leading to expanded production and processing techniques. By the 1980s, efforts focused on preserved forms like salted and fermented myeongnanjeot, ensuring consistent quality and broader distribution while reinforcing its cultural role in everyday and festive meals.

In Japanese Culture

The history of pollock roe in Japan traces back to the early 20th century, particularly during the Japanese colonial period in Korea (1910–1945), when salted roe, known as , was imported as a preserved for urban markets. These imports catered to the growing demand for seafood preserves amid Japan's expanding trade networks, establishing pollock roe as an early staple in coastal and urban cuisine. The modern spicy variant, mentaiko, emerged post-World War II through the efforts of Korean-born entrepreneur Toshio Kawahara, who founded the company Fukuya in Fukuoka's Hakata district. In 1949, Kawahara adapted a Korean marinated roe recipe by incorporating chili peppers to suit Japanese palates, introducing it commercially at his grocery store and sparking its rise as a regional specialty. This innovation built on earlier salted tarako traditions but added a distinctive spicy profile that differentiated it in the Japanese market. Japan's access to Alaskan pollock fisheries expanded dramatically in the , following the rebuilding of its fishing fleet and international agreements allowing operations in the starting in 1952. This surge in supply from , where pollock roe became a key export to , fueled the growth of the domestic industry by providing abundant, high-quality raw material for processing. By the , amid Japan's broader , mentaiko experienced a consumption boom, positioning it as an affordable luxury accessible to middle-class households through mass production and distribution. In Hakata, Fukuoka, pollock roe processing evolved into a major economic hub, with over 200 manufacturers by the late 20th century supporting local employment and exports. This cluster drove significant revenue, as mentaiko became a flagship product contributing substantially to Fukuoka's seafood industry value. Culturally, mentaiko integrated into traditions like the festival, where it features in special offerings and street foods during the July celebrations, symbolizing regional pride and communal feasting.

In Russian Culture

Pollock roe has been utilized in fisheries since the early , as industrial-scale fishing expanded in the region under tsarist and later Soviet efforts to develop local resources and compete with Asian fisheries. During the 1930s, Soviet assessments of fish stocks in the western identified as a promising resource, leading to expanded exploitation plans for Pacific fisheries to support national and industrialization. Following , pollock roe emerged as a vital protein source in remote areas like Kamchatka and , where it was processed and distributed to bolster local diets amid postwar shortages and the growth of the Soviet fishing fleet. The marked a turning point with the of state fisheries, shifting focus from domestic use to ; exports of pollock roe to surged, rising from over 6,000 metric tons in 1990 under Soviet supply to approximately 25,000 metric tons in 1993. In Russian culture, pollock roe, referred to as ikra mintaya, holds significance as an economical alternative to sturgeon in festivities, often served on or in simple preparations to evoke traditional abundance. Industrial production of pollock roe is centered in , a key hub for processing that supports both local consumption and export operations. A notable milestone occurred in the 2000s, when Russian fisheries increased penetration of the Chinese market for pollock roe, driven by rising demand and processing capabilities, with China absorbing a growing share of exports alongside traditional Asian buyers. As of 2021, Russia remained a major exporter, though climate impacts on stocks pose ongoing challenges.

Culinary Applications

In Korean Dishes

In Korean cuisine, pollock roe, referred to as myeongnan, is a versatile ingredient often transformed into myeongnan-jeot through salting and fermentation, creating a savory fermented seafood product that serves as a key banchan side dish alongside steamed rice. This preparation highlights its role in everyday meals, where the intact roe sacs are carefully washed in salt water before being layered with coarse sea salt to cure, developing a deep umami flavor over time. These methods emphasize its adaptability in balancing bold flavors in multi-dish Korean spreads.

In Japanese Dishes

In , pollock roe, known as tarako when salted and mentaiko when spiced with chili, serves as a versatile ingredient prized for its briny, umami-rich flavor that enhances both traditional and contemporary dishes. Tarako offers a mild, creamy texture ideal for subtle preparations, while mentaiko introduces a spicy kick derived from its curing process with chili peppers. Signature dishes featuring pollock roe include mentaiko pasta, a popular fusion where hot spaghetti is tossed in a creamy sauce of , , and spicy mentaiko, allowing the heat to release the roe's flavors for a silky, umami-packed result. This dish, often garnished with or , exemplifies mentaiko's role in Western-influenced Japanese (wafu) pasta. Similarly, tarako appears as a topping for noodles, where thin slices are scattered over steaming bowls to add a salty contrast to the broth. For raw consumption, tarako gohan is a simple yet cherished everyday meal, consisting of thinly sliced tarako draped over hot steamed rice, where the warmth gently softens the roe sacs and intensifies their natural brininess. In sushi preparations, pollock roe features as nigiri, with a small portion of tarako or mentaiko placed atop vinegared rice and sometimes wrapped in nori for a fresh, oceanic bite. It also fills onigiri rice balls, molded into triangles with mentaiko mixed into the rice or stuffed inside, providing portable umami in bentos or snacks. Modern innovations highlight pollock roe's adaptability in , such as mentaiko , a novelty blending the spicy roe with sweet milk for a contrasting sweet-savory treat popularized in Fukuoka, the heart of mentaiko production. Likewise, mentaiko croquettes incorporate the roe into mixtures, breaded and fried for crispy exteriors that yield to creamy, spiced interiors, often served as appetizers in casual eateries. Serving etiquette emphasizes freshness, particularly in coastal regions like Fukuoka, where pollock roe is consumed soon after curing to preserve its delicate texture; heat from accompanying hot rice or pasta is traditionally used to activate and burst the roe's flavors without overcooking.

In Russian Dishes

In , pollock roe, known as ikra mintaya, is traditionally prepared by salting and is often consumed as a zakuski-style appetizer spread on pancakes or , providing a creamy, briny contrast to the soft texture of the bread or pancakes. This simple presentation highlights its mild flavor and is popular during festive gatherings alongside other ikra varieties.

Nutritional Profile

Composition

Pollock roe, derived from the (Gadus chalcogrammus), consists primarily of water, with approximately 70% moisture content in its fresh form. The macronutrient profile includes 15-23% protein on a wet weight basis, providing high-quality essential , alongside 2-3% and low carbohydrates at 0-5%. Among micronutrients, pollock roe is notably rich in , containing up to 10 mcg per 100 g. It also contains vitamins A (~90 mcg per 100 g) and E (~7 mg per 100 g). It supplies significant minerals, including at around 40 mcg per 100 g and at approximately 390 mg per 100 g. The fraction, comprising 5-10% on a dry weight basis, features a profile high in omega-3 polyunsaturated fatty acids such as DHA and EPA, which account for 20-24% each of total , contributing to 30-40% polyunsaturated fats overall. levels range from 250-400 mg per 100 g. Variations in composition occur between fresh and salted forms; fresh roe maintains higher moisture (around 72%), while salting reduces it to about 65%, thereby concentrating protein, , and other nutrients.

Health Aspects

Pollock roe provides notable health benefits, particularly through its omega-3 fatty acids, which support cardiovascular health by lowering triglycerides and reducing inflammation associated with heart disease. These essential fatty acids, including DHA and EPA, contribute to improved heart rhythm regulation and overall endothelial function, as evidenced by nutritional analyses of roe. Additionally, the and content in pollock roe bolsters immune function; acts as an to protect cells from , while B12 supports the production of immune cells and red blood cells. At 100-150 kcal per 100 g, pollock roe serves as a low-calorie protein source suitable for in moderation. Despite these advantages, potential concerns arise with consumption, especially in salted preparations common for pollock roe products like mentaiko, which typically contain 1500–3000 mg of sodium per 100 g, with traditional variants reaching up to 7000 mg, potentially elevating and risk for those with cardiovascular vulnerabilities. Fish-sensitive individuals may experience allergic reactions, including , due to proteins in pollock roe, necessitating avoidance. Mercury levels remain low in pollock roe, typically below 0.031 ppm, and are routinely monitored by regulatory bodies, rendering it a low-risk option compared to higher-mercury . Research highlights anti-inflammatory properties in pollock roe, with studies identifying bioactive peptides from its extracts that inhibit pro-inflammatory pathways like NF-κB, potentially aiding conditions involving chronic inflammation. For adults, a recommended intake of 50-100 g weekly balances these benefits against sodium accumulation, aligning with broader seafood guidelines for omega-3 enrichment. Compared to beef, which offers negligible omega-3s (around 0.05 g per 100 g), pollock roe provides substantially more (approximately 2.3 g per 100 g), though it falls short of salmon roe's higher levels (about 4.2 g per 100 g).
