Premium Alginate Polymer for Spherification, Encapsulation & Hydrogel Engineering

99% Pure | High Viscosity (724 cP) | Derived from Natural Brown Seaweed

Not all sodium alginate is created equal. Many commercial alginate products are blended with sugars, carriers or anti-caking agents to improve handling and speed up dissolution. While convenient, these additives reduce the amount of active polymer available to form strong calcium alginate gels.

Our philosophy is simple:

Buy polymer—not filler.

This premium high-viscosity sodium alginate contains approximately 99% pure alginate polymer, delivering maximum gel strength, excellent structural integrity and outstanding encapsulation performance for both culinary and laboratory applications.

Why Choose High-Viscosity Alginate?

✔ High viscosity (724 cP)

✔ Approximately 99% pure alginate polymer

✔ Derived from natural brown seaweed

✔ Produces exceptionally strong calcium alginate gels

✔ Excellent bead strength and structural stability

✔ Ideal for biological encapsulation and molecular gastronomy

✔ Supplied in a reusable polypropylene laboratory tub

Typical Applications

🧫 Preta Pearls & Biological Encapsulation

Create calcium alginate capsules for microbial storage, biological carriers and innovative mushroom cultivation systems.

🍽 Alginate Spherification

Perfect for direct and reverse spherification, cocktail pearls, fruit caviar, popping boba and liquid-centred culinary creations.

🧬 Laboratory & Research

Suitable for hydrogel preparation, biomaterials research, encapsulation studies and polymer engineering.

🌱 Agricultural Biotechnology

Ideal for microbial inoculants, seed encapsulation and controlled-release biological formulations.

🦷 Specialised Technical Applications

Suitable for selected dental, moulding and casting applications requiring high gel strength and dimensional stability.

Typical Working Concentration

Most applications use between:

0.3–0.5% Sodium Alginate

The exact concentration depends on the desired gel strength, bead size and application.

Because this product contains virtually no inactive fillers, a little goes a long way.

STS Flash-Hydration Method

Pure high-viscosity alginate hydrates rapidly and can form surface “fish-eyes” if added too quickly.

For best results:

1. Sprinkle the powder slowly into vigorously stirred water.
2. Blend using a high-shear or immersion blender.
3. Allow the solution to hydrate completely.
4. Where sterile media are required, autoclave or pressure-cook for 10–15 minutes to complete hydration and remove entrapped air.

This produces a smooth, homogeneous alginate solution suitable for encapsulation and laboratory work.
