My life-long resistance to the concept of “sea food” has given way to the emergence of algae and seaweed as the snacks of choice. Seabed vegetables have reinvented our understanding of a whole cuisine category amid a looming consensus that kelp is the new kale.

Ten varieties of edible marine algae, seaweed, and kelp form the basis of the best sea salad. With multiple health benefits and manageable risks, they can be bought prepackaged from suppliers. Recipes for homemade snacks allow standalone variations and side dishes.

To navigate the menu, we’ll begin with the basis for the algae types and then consider popular prepackaged offerings. Later we’ll review the health benefits and consider recipes for homemade ocean tuck.

11 Best Prepackaged Marine Algae Snacks

Organic Roasted Seaweed Sheets

Various suppliers prepare this popular snack. They are available in offerings free of preservatives, artificial flavorings, and GMOs. As the name suggests, these are compressed seaweed sheets desiccated through roasting.

Ideal for slimmers, at 25 calories to the pack, these snacks are rich in fiber, protein, minerals, and vitamins. They come in multipacks, which makes them a good choice for packed lunches. Flavors include salt, teriyaki, and wasabi. Mix packs allow an assortment of these flavors.

Spicy Thai & Spirulina Kelp Jerky

Like beef jerky, this chewy tough-textured treat is packed with protein — 0.35 oz in each pack. Instead of departed cows, dried kelp and shitake mushroom form the substrate. Bolstering ingredients are Thai spice rounds out the flavoring.

Seaweed Chips

An innovative take on tortilla chips, this version is made using sustainably harvested Atlantic Ocean algae. Their crispy texture reprises the original Mexican snack, and they are offered in three flavors: original, sweet chili, and super sushi.Dulse Smoked Flakes

Capturing the pork rind flavor of Irish algae, dulse flakes provide a smoky breakfast taste. A popular commercial version provides applewood flavor. The bits are suitable as a standalone snack or as a flavoring for a salad.

Dulse has a deep scarlet color which enhances the visual effect of a meal. It doesn’t require any reconstitution or cooking and can be eaten as is. 

Dulse flakes are harvested in the wild. They are dried naturally, which preserves the density of their nutritional value. The smoking process does something to dilute the nutritional density, but much of the health benefit is left intact. As a substitute for chemically enhanced smoky seasoning, it wins on nutrition and (in my view) taste.

Tempura Seaweed Chips

These snacks showcase tempura — a traditional cooking method from Japan, which was popularized in the districts of Nagasaki and Tokyo. It provides a distinctive delicate crunch.

Tempura seaweed chips use sheets of savory seaweed, sustainably harvested from the Pacific. They are dipped in tempura-spiced batter and fried. Additional flavoring is added to round out the taste.

Sea Moss Gel

Also known as Chondrus Crispus, sea moss is a red alga found along the shores of the Caribbean Islands, Europe, and North America. Its health benefits are legion and the subject of growing research.

Sea moss gel is created in the most organic way imaginable — water immersion, followed by blending. Known as “the vegan gelatin,” it is an excellent additive for smoothies. It can be consumed on its own or with fruit. Bladderwrack and elderberry are popular nutrition-boosting additives. 

Onigiri Rice Ball Seaweed Wrappers

In Japanese cuisine, onigiri is a rice ball prepared with short-grain rice. This ball is molded into a triangle, which is then wrapped in nori. While the rice may be plain, it is also served with fillings or toppings.

Onigiri Rice Ball Seaweed Wrappers provide prefabricated nori triangles. Not intended as standalone snacks (although they’ll do as nori sheets if you’re ravenous), these are intended to support filler snacks.

Kimchi Sea Snacks

These are a Korean take on nori sheets. Ocean harvested seaweed is pressed into thin sheets. These are roasted in canola, sesame oil, and salt. They are lathered with kimchi flavoring for the snack’s distinctive taste.

Kimchi Sea Snacks are sold in packs of twenty. They are famous for their uniquely Korean flavor, and in addition to their role as standalone snacks may be used to complement light lunches. They can be ground and added to soups.

Crunchy Seaweed Chips

These kid-friendly treats have the crunch associated with chips and pretzels. But they are rich in marine minerals. Seaweed chips are rice-wrapped seaweed curls seasoned lightly and with a pinch of salt. They’re good on their own or sprinkled over a salad. They are totally lacking in artificial preservatives, flavorings, or colors. 

Fried Wasabi-Seasoned Seaweed Chips

This all-natural snack is reminiscent of cheese puffs but with a solidly Asian marine constitution. The core is an organic ocean-harvested dried seaweed chip. This is dipped in wasabi-flavored batter and deep-fried in a blend of natural vegetable oils. 

Kelp Seasoning

While not a standalone snack, this seasoning helps add punch to your nibbles. The key ingredient is dried Alaskan kelp, which is mixed with bagel seasoning. This makes a great savory add-on for savory oatmeal or sea-flavored bagels.

Sea Stacks

Sea stacks are compressed seaweed in finger shapes. They have been rolled, baked, and flavored in wasabi. Each stick is free of trans fat, coloring and preservatives, and packed with healthy minerals.

12 Sea Salad Recipes You Can Try

While ready-made snacks have a convenience that speaks for itself, rolling your own allows more control of the taste and variety. Experimentation can draw a good snack deeper into the orbit of your personal preference. In what follows below, remember two recurring ideas:

  • Reconstitution happens when dried seaweed is immersed in and absorbs water. How long it takes depends upon the variety of seaweed involved.

Types Of Edible Algae

Also known as “sea vegetables,” seaweed is marine algae that grow in red, green, and brown varieties in the ocean. They are characterized by a salty taste owing to their saturation with amino acids. The Japanese call this savory signature “umami.” Algae is a core component of Japanese and other Asian cuisines. Below we list the best-known types:


Also known as “sea oak,” arame is a dark wispy brown alga. It is popular in Japanese cuisine, served alongside vegetables, in casseroles, and soups. This alga has a semi-sweet taste. After reconstitution — through immersion in water — it can be boiled or sauteed.


Chlorella is a monocellular alga found in freshwater. Of the thirty-plus species, two types are most commonly used. Its hard cell wall makes it indigestible to humans, so it is processed and provided in extract form for cooking.


While we associate seal salad with Asian cuisine, dulse is seaweed of Irish origin. It has made its way to Canadian cuisine too. It is rich in potassium and iodine, elements that the human body needs to produce thyroid.

Known as “the bacon of the sea,” dulse resembles red lettuce. On frying, it tastes much like a pork rasher. The weed occurs naturally in parts of Western Europe and is fit for cultivation.


This is a jet-black alga with small leaves. It grows off the coastline of Korea, China, and Japan. Its appearance resembles tea leaves, and folklore has it that consumption of the weed is good for cultivating thick black hair.


Kombu is Pacific ocean kelp. It is thick, dark green, and a favorite feature of Japanese broth. It has about two dozen variations, including the popular Ma-kombu. This high-quality kelp is sweet-tasting, with thick green leaves. Rishiri kombu is a winning ingredient in Japanese ramen noodles.


Mozuku is a pea-green weed that is largely farmed by hand. A product of Okinawa, it grows in shallow freshwater, with a harvest the Springtime. Mozuku is popularly associated with longevity.


By far the most popular presentation, nori is marine algae dried and pressed into a thin layer. It is known as a key ingredient in sushi and is also used for ramen noodles and rice bowls as a garnish.


Aonori is formed by drying laver (edible seaweed). It is used as a garnish. Popular accompanying dishes are octopus balls (Takoyaki), okonomiyaki (pancakes), and yakisoba (fried noodles).

Norishio is a popular Asian snack consisting of salt and aonori.


Ogonori is red algae that thrive in the calm, sandy, shallow bottoms of the Atlantic. The twigs are tangled and fine, their color varying in proportion to the light they receive. Thus it straddles the spectrum between yellow-pink and reddish-brown.

The main interest in ogonori is its saturation with agar-agar, a substitute of choice for animal gelatin. This dish is popular in Hawaii, the Philippines, and Japan. 


Samphire is the name given to a class of succulent, salt-tolerant aquatic vegetables. Also known as “sea asparagus” — because of its structure — the succulent occurs widely on the Eurasian coast and Australia, where it’s earned pride of place in the “bush tucker” cuisine.

Sea Grapes/Umi Budou

Umi Budou is a product of the Okinawa prefecture. This alga is referred to as sea grapes because it is shaped in clusters of grape-green kernels. The glistening fineness of the “grapes” also earns the moniker “green caviar.”

Sea Lettuce

These are bright green algae whose .lobed leaves have coarse, ruffled edges. They resemble lettuce and are presented in sheets. Sometimes the leaves are flat and sometimes oval in appearance, with perforating holes.

The color of sea lettuce changes to shades of black after being dried by the sun.


Due to its cooked appearance, wakame is often referred to as ‘wild mustard”. Its flavor is much milder, though. Wakame is an edible sea vegetable that appears wild off the Australian coast. It is farmed extensively in Korea and Japan.

The most common presentation of wakame is dried. It is also sold salted when it is sealed and refrigerated.

Wakame is best known as the vegetable in miso soup. Before being used, it needs to be reconstituted, which involves immersing it in water. The wakame expands its volume as it hydrates. Factor this when selecting quantities for preparation.

Health Dynamics Of Marine Algae

We touch on the medical pros and cons of snacking off the seabed:

Health Benefits

The types of seaweed differ in their chemical composition, and therefore in the balance of nutrients they provide. As a class, they are rich in nutritive minerals. They deliver vitamins A, B, C, E, and K and are plentiful sources of iodine and iron.

Seaweeds are a rich source of antioxidants. This protects the body from oxidant stress and fights cellular-level inflammation. The iodine saturation helps with thyroid regulation, and the fiber-richness combats diabetes.

Fiber plays a role in the gut health of humans. It feeds intestinal bacteria, which anabolise the fiber into compounds needed to maintain the health of the ailment. By reducing blood cholesterol it contributes to heart health, and overall, fiber plays a constructive role in weight loss.

Health Risks

High levels of seaweed consumption will expose the consumer to iodine saturation. Most people can handle this, but the iodine-sensitive might experience thyroid dysregulation. This is easily remedied by cutting down the level of consumption.

Overall, seaweeds have a high level of heavy metals, and consuming them in large quantities over an extended time will have low-level toxic effects.

What Are The Best Kelp Algae & Seaweed Snacks

Algae and kelp have matured from ocean weed to vegan feed. They are healthy, versatile standalone snacks that complement a range of popular dishes. Best of all, they’re delicious.
