Modernist Pantry Pure Sodium Alginate 100g (4oz) — Non‑GMO Vegan, Refined for Spherification & Cold Gels

Pure Sodium Alginate is a food‑grade seaweed‑derived hydrocolloid used to create delicate spheres, gels, and creamy textures in modernist cooking.

Made from 100% natural brown seaweed and certified OU Kosher, this 100 g / 4 oz pouch supplies culinary professionals and home experimenters with a reliable, non‑GMO, vegan thickening and gelling agent. Its refined particle size and controlled viscosity make it especially suited for both direct and reverse spherification techniques as well as stabilizing sauces, thickening dairy alternatives, and forming cold gels without heat.

How does this sodium alginate help me make spheres and gelled textures?

When dissolved in water or a flavored liquid, sodium alginate reacts with a calcium bath to form a thin membrane or a uniform gel, depending on the method. This product’s formulation balances solubility and gel strength so you can produce consistent spheres and soft gels that hold shape yet burst cleanly on the palate.

• Suitable for direct spherification: mix alginate into flavored liquid then drop into calcium solution.
• Works for reverse spherification: add calcium into the flavored liquid and drop into alginate bath for longer‑lasting spheres.
• Creates cold-set gels and stabilizes emulsions without heating.
• Measured viscosity minimizes air bubbles and yields smooth surfaces.

What concentration and technique should I use for reliable results?

Typical starting concentrations are 0.5–1.0% alginate (by weight) for spherification and up to 2.0% for firmer gels or thickened sauces. Always dissolve gradually with high‑shear stirring or an immersion blender, then allow the mixture to hydrate and degas before use.

• Start at 0.5% for thin, delicate spheres and 1.0% for firmer pearls.
• Use 0.5–1.0% calcium chloride or calcium lactate in the bath depending on flavor sensitivity.
• Blend thoroughly and refrigerate 1–4 hours to remove bubbles and fully hydrate.
• Rinse finished spheres briefly in clean water to remove excess calcium taste.

Can I use this product in sauces, dairy, or plant‑based recipes?

Yes. Sodium alginate thickens and stabilizes without altering flavors, and it performs well in both dairy and vegan formulations. It helps prevent syneresis (liquid separation) and adds body to cold preparations without needing heat.

• Stabilizes emulsions like vinaigrettes and mayonnaise alternatives.
• Thickens cold creams, puddings, and plant milks without cooking.
• Works with acidic or alcohol‑based liquids when paired with appropriate calcium sources.
• Food‑grade purity ensures safe culinary use—avoid industrial grades.

How should I store and handle this ingredient for best shelf life?

Keep the pouch sealed and stored in a cool, dry place away from strong odors and humidity. Proper storage preserves particle quality and prevents clumping, ensuring consistent dispersibility when you prepare solutions.

• Reseal the pouch or transfer to an airtight container after opening.
• Store between 10–25°C (50–77°F) in a dry environment.
• Avoid contamination with metal; use plastic or glass utensils for mixing.
• Typical shelf life: several years when kept sealed and dry; check lot information for specifics.

This Modernist Pantry Pure Sodium Alginate is crafted for chefs, bartenders, culinary students, and at‑home modernist cooks who want predictable, high‑quality performance for spherification, cold gelling, and texture design. If you’re experimenting with molecular techniques, stabilizing plant‑based sauces, or creating novel plated elements, this food‑grade, non‑GMO, vegan and OU‑certified alginate gives you a dependable foundation without unwanted additives.
