What is Masago?

Masago is the roe of a group of fish known as smelts, including the capelin smelt found in the North Atlantic, Arctic, Pacific oceans and the shishamo smelt found in the Pacific Ocean near Japan. In Japanese, the word “masago” (which translates to “sand”) denotes a little object. Capelin is considered a forage fish, meaning it’s an essential food source for larger fish, seabirds, and marine mammals. Once female capelin reaches around two to four years of age, the fish begins to release eggs or roes. The role of capelin, usually dull yellow, is harvested from female capelin and then dyed to make it more appealing when applied to dishes.

How Long Does It Last?

Like any delicate culinary gem, Masago requires proper care to maintain its freshness and quality. When stored correctly, it can stay enjoyable for a reasonable period. An unopened package, whether refrigerated or frozen, can generally last several months beyond the expiration date printed on the packaging. However, once opened, the clock starts ticking. An opened container should ideally be consumed within a week to ensure the best taste and texture.

Store the opened container in the coldest part of your refrigerator to extend its shelf life, keeping it away from strong-smelling foods to prevent flavor absorption. For those looking to keep it on hand for an extended period, freezing is an option. When freezing, divide it into small portions, place it in airtight containers, and label it with the date. Frozen masago can maintain its quality for up to six months. Remember, proper storage is the key to preserving it to its delectable essence, ensuring every bite retains its delightful crunch and flavor.

Side Effects

While it offers a range of health benefits, it’s necessary to be aware of potential side effects associated with its consumption.

1. Allergic Reactions

One of the primary concerns when consuming seafood products like masago is the potential for allergic reactions. Some individuals may be allergic to fish or seafood, including roe. The signs of an allergic reaction can range from mild itching and hives to more severe symptoms like difficulty breathing or anaphylaxis. If you have a known seafood allergy, avoiding it and related products is crucial to prevent adverse reactions.

2. Mercury Concerns

It is a strong metal that can accumulate in seafood, including fish roe like masago. While it comes from smaller fish with lower mercury levels than larger predatory fish, regular consumption can still contribute to mercury exposure over time. High mercury levels can cause developmental and neurological problems, especially in young children and pregnant women. To mitigate this risk, consuming it in moderation is advisable, especially if you are in a high-risk group.

3. High Sodium Content

Masago is often seasoned with salt to enhance its flavor and preserve its texture. As a result, it can have a relatively high sodium content. Overusing sodium intake can lead to high blood pressure problems, increased risk of heart disease, and water retention. Individuals with hypertension or those aiming to reduce their sodium intake should be mindful of their overconsumption and choose lower-sodium alternatives whenever possible.

4. Caloric Density

While it is rich in nutrients, it’s also calorie-dense due to its fat content. Overindulgence in calorie-dense foods can contribute to weight gain over time, leading to various health issues, including obesity and related complications. To enjoy its benefits without excessive calorie intake, practice portion control and balance it with other nutrient-rich foods.

5. Microbial Contamination

Like all seafood, it is susceptible to microbial contamination if not handled and stored correctly. Consuming raw or improperly stored masago can lead to foodborne illnesses such as bacterial infections or food poisoning. To minimize the risk of microbial contamination, ensure that the type you consume is sourced from reputable suppliers, stored at the appropriate temperature, and prepared hygienically.

Final Thoughts

Masago isn’t just a treat for the taste buds; it’s also a nutrient-packed ingredient that offers several health benefits. From being an abundant source of essential nutrients like vitamins B12 and selenium to providing heart-healthy omega-3 fatty acids, it also brings a lot to the table regarding nutrition. While it offers numerous advantages, it’s essential to consume it mindfully to avoid potential side effects. Allergic reactions, mercury concerns, high sodium content, caloric density, and microbial contamination are factors to consider when indulging in it.
