Seaweed Powder

Botanical Name: Ascophyllum nodosum

Country of Origin: Canada

English Name: Seaweed Powder

French Name: Poudre d’Algues Marines

Also Known As: Rockweed Powder, Ascophyllum Powder, Brown Seaweed Powder, North Atlantic Seaweed

Part Used: Whole dried fronds of Ascophyllum nodosum

Description: Seaweed Powder is made from the dried fronds of Ascophyllum nodosum, a brown algae native to the North Atlantic, commonly found along the rocky coasts of Canada, Ireland, and Northern Europe. The algae grows attached to rocks in intertidal zones, forming dense, long fronds that can reach 1–2 meters in length. Fresh fronds are olive green to dark brown with a slightly glossy surface and naturally occurring air bladders that help the algae float in seawater. Harvesting occurs during peak growing seasons when the fronds are mature, firm, and dense.

After harvesting, the seaweed is carefully washed to remove sand, salt, and natural debris. Drying is performed using controlled air or low-temperature methods to maintain colour, structural integrity, and natural texture. Once dried, the fronds are firm, with visible ridges and a slightly flexible texture. This ensures that the natural characteristics of Ascophyllum nodosum are preserved before milling.

The dried fronds are then finely milled into a uniform, free-flowing powder with a smooth texture. The powder retains the marine aroma of the seaweed, while the fine particle size allows for easy blending, accurate measurement, and incorporation into a wide variety of applications. The resulting powder maintains the botanical identity of Ascophyllum nodosum and reflects the original morphology of the whole algae in a convenient powdered format.

Uses: Seaweed Powder from Ascophyllum nodosum is used in culinary applications such as seasoning blends, soups, smoothies, and beverages, providing a natural marine ingredient with texture and colour. It is also used in cosmetic formulations including soaps, bath salts, facial masks, and scrubs, offering a fine powder for blending and textural enhancement. Additionally, the powder is suitable for craft projects, botanical collections, and educational displays illustrating marine algae morphology and coastal ecology. Its fine texture, uniform particle size, and natural brown hue make it ideal for blending, formulation, and infusion-based applications in both home and professional settings.

Storage: Store in a cool, dry, dark place in an airtight container. Refrigeration not required.
