Seatrose (Seaweed Dietary Fiber)

A soluble dietary fiber derived from brown seaweed (Laminaria and Saccharina species), composed primarily of low-molecular-weight alginate fragments together with fucoidan and laminarin. Designed to deliver soluble-fiber and seaweed-marker labeling without the strong viscosity contribution of standard alginate.

Off-white to light tan free-flowing powder. Highly water-soluble with low to moderate viscosity in solution, mild characteristic marine note.

We supply food-grade Seatrose Seaweed Dietary Fiber from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.

Common market grades are differentiated by total fiber content (75 percent versus 90 percent minimum), residual ash, and fucoidan and laminarin content for products positioned around bioactive marine-polysaccharide claims.

Bulk and reduced-MOQ shipments. Batch-level COA covering total dietary fiber, ash, residual heavy metals (particularly arsenic, regulated for seaweed-derived ingredients), and microbiology.

Seaweed-derived dietary fibers have been consumed in East Asia for centuries through traditional kombu, wakame, and nori-based foods, and are recognized for soluble-fiber and trace-mineral contribution to the diet.

Industrial production starts with food-grade brown seaweed harvested from cultivated and wild beds in coastal China, Korea, and Japan. The seaweed is washed, milled, and subjected to controlled hydrolysis to depolymerize the long-chain alginate into low-molecular-weight fragments that retain solubility without the gelling action of full-length alginate.

Recognized as a permitted food ingredient by major regulatory bodies. Specific seaweed-source heavy-metal limits, particularly for arsenic, are managed by feedstock screening and downstream purification.

The strategic role in formulation is fiber and marine-source positioning without the heavy texture impact of unmodified alginate. At typical dose of 1 to 5 percent in finished food, the ingredient delivers measurable soluble-fiber content alongside clean-label seaweed-marker labeling, which is the principal commercial driver in Asian and Western functional-food markets.
