About This Product
Louis Francois Agar Agar is a natural gelling agent (E406) extracted from Gracilaria red algae (Rhodophyceae family). Presented as a white to cream-coloured powder, it is odourless, tasteless, and widely used across culinary, industrial, and pharmaceutical applications.
This thermoreversible hydrocolloid forms a hard, transparent, and brittle gel after boiling and cooling. It is ideal for producing hot jellies, molded products, and low-fat formulations. Compared to typical supermarket or commercial-grade agar powders, Louis Francois Agar Agar provides more precise gel strength, cleaner flavour neutrality, and a smoother texture, making it a preferred choice for professionals in pastry and gastronomy.
Use:
Incorporation:
Agar must be fully dissolved in a boiling liquid to activate its gelling properties. Once dissolved, it sets upon cooling, forming a firm gel that can be reheated to 92°C to re-liquefy. It is best used in water-based systems, and its gelling capacity may be reduced in acidic environments or in the presence of alcohol.
Application:
-
Hot or Molded Jellies: For desserts or plated elements that require defined structure
-
Low-Fat Dairy or Plant-Based Products: Improves body and mimics creaminess without fat
-
Pastry & Confectionery: Used in gel inserts, pâte de fruits, fruit sheets, and clear toppings
-
Instant Dessert Mixes & Ice Creams: Acts as a stabilizer for texture and shape retention
-
Savoury Preparations: For terrines, soups, sauces, and aspics
-
Non-Food Uses: Applicable in biotech, pharmaceutical, and cosmetic products

Differences from Similar Gelling Agents:
-
Compared to supermarket agar powders, Louis Francois Agar Agar is more consistent in gel strength, with superior texture clarity and purity.
-
Unlike gelatin, agar sets quickly at room temperature and remains stable at higher temperatures, making it ideal for warm-service or heat-stable applications
-
Less suitable for freezing/thawing compared to gellan or LM pectins, but more heat stable than many gelatine-based systems.
-
Offers stronger, firmer gels than carrageenan or citrus fibres, with faster setting and higher melting point.
Origin:
Extracted from Gracilaria red algae (Rhodophyceae family).
