Alginate - Spherification Gelling Agent - 750g - Sosa
Available format: 750 g tub.
Sosa Alginate is the benchmark gelling agent for spherification in creative gastronomy: flavour caviar, liquid pearls, ravioli shapes and aromatic beads. In direct spherification, it is blended into the liquid to be shaped; in reverse spherification, it forms the gelling bath. On its own, it acts as a thickening agent.
- Use: Gelling agent in the presence of calcium — thickening agent on its own.
- Dosage: 5 g/kg.
- Applications: Direct and reverse spherification, all water-based liquids with pH ≥ 4.
- Dietary: Vegan · Vegetarian · Clean Label · Non-GMO · Kosher certified · Halal certified.
♥ Expert tip: Alginate never works alone — it is always used in combination: with Clorur (calcium bath) for direct spherification, or with Gluconolactat for reverse spherification. If your preparation is acidic (pH < 4), adjust the pH first with Citrate.

Description
expand_moreThe foundational gelling agent for spherification
Sosa Sodium Alginate is a white plant-based powder extracted from brown marine seaweeds. It is a natural polysaccharide that forms a supple, resistant gelled membrane on contact with calcium — the fundamental principle of spherification. On its own, it acts as a thickening agent; in the presence of calcium (Clorur in direct spherification, or naturally occurring calcium in reverse spherification), it gels instantly from the outside inwards.
Direct Spherification
Suited to water-based liquids with a pH ≥ 4 and a water content above 80%. Alginate is blended directly into the preparation, which is then dosed into a Clorur bath. Gelling occurs from the outside inwards.
Caption: Direct spherification — 1. Blend Alginate into the preparation, mix (rest 10 min). 2. Prepare the Clorur bath (rest 10 min). 3. Dose the preparation into the Clorur bath (30 seconds). 4. Collect the spheres, rinse in clean water, serve.
Note: If the preparation is too acidic (pH < 4), adjust first with Citrate before incorporating the Alginate. Alginate is not compatible with fatty or heavily alcoholic mediums.
Reverse Spherification
Suited to liquids naturally rich in calcium (dairy products) or enriched with Gluconolactat. Here, Alginate forms the gelling bath — always prepared with still mineral water (calcium-free). The calcium-rich preparation is dosed into it, forming beads that remain liquid at the centre indefinitely.
Caption: Reverse spherification — 1. Blend Gluconolactat into the preparation, mix (rest 10 min). 2. Prepare the Alginate bath in still mineral water (rest 10 min). 3. Dose the preparation into the Alginate bath (3 minutes). 4. Collect the spheres, rinse in clean water, serve.
