Carrageenan (CAS No.: 9000-07-1, E407)
General Definition
-
Source: A natural polysaccharide extracted from red seaweed.
-
Structure: Large, flexible, helical molecules with high elasticity.
-
Functionality: Forms gels of different strengths at room temperature.
-
Key Advantage: Thixotropic property – viscosity decreases under stress and recovers once stress is removed, making it easy to pump and process without losing structure.
-
Effect on Products: Does not alter color, flavor, or aroma; only provides texture and viscosity.
Extraction Methods
-
Refined Process:
-
Carrageenan is fully dissolved out of the seaweed’s cellulose matrix.
-
Produces a clean, transparent, high-purity product.
-
-
Semi-Refined Process:
-
Retains some cellulose within the structure.
-
Lower cost, excellent gel strength and binding properties.
-
Final gels are not visually transparent compared to refined carrageenan.
-
Applications
| Refined Carrageenan | Semi-Refined Carrageenan |
|---|---|
| In frozen foods, beverages, desserts, sauces (viscosity enhancer) | In meat products (binder, thickener) |
| In dairy products (thickener, stabilizer) | In dairy products (texture improver) |
| In milk puddings, phosphates, starches, and other gums (anti-coagulant, gelling agent) | In jellies and confectionery (gel strength enhancer) |
| As a fat replacer in processed meats (improves water retention and volume) | In ready-to-eat foods (viscosity modifier) |
| In sausages and salami (improves softness and sliceability) | In ice cream (texture stabilizer) |
| As a gelatin substitute in transparent, elastic jellies | In water- and milk-based desserts (thickener) |
| In jams and marmalades (gel formation) | In wine, vinegar, and beer (clarity enhancer) |
Highlighted Features
-
Thixotropy: Ensures smooth processing and structural recovery.
-
Versatility: Widely used in food, beverages, dairy, meat, desserts, jams, and alcoholic products.
-
Cost Efficiency: Semi-refined form is economical, while refined form provides superior clarity and purity.
