Applications

Carrageenan, a soluble fiber & hydrocolloid derived from red seaweed, is a natural food ingredient that has been used for hundreds of years in cooking all over the world. 

It often replaces synthetic and animal-based products (like Gelatin). It is also commonly used in vegetarian and vegan diets and lifestyles.

Kappa Semi-Refined Carrageenan is used in a variety of commercial applications as a gelling, thickening, and stabilizing agent, especially in the food industry for the manufacturing of meat products, condiments, pet foods, air fresheners, and for wort clarifying, etc. 

Features

E-No. E 407
Origin Seaweed extract
Chemical composition 1. Family of salts of sulphated galactans (high sulfate content 18–40%); 2. D-galactose, D-(3-6)-anhydro-galactose, sulfate ester groups
Nutritional value (in 100 g) – metabolism 0 kJ (0 kcal); No resorption
Fibre content 100% Soluble fibre
Toxicology Global approval as food additives; viscosity: minimum 5 mPa s as 1.5% solution at 75 °C (167 °F) (average MW of 100 kDa); Europe: ADI (75 mg/kg BW per day) and MW limit of maximum 5% below 50 kDa
Solubility at low temperature (H2O) κ-C: only Na+ salts are soluble, limited swelling of K+ and Ca2+ salts; ι-C: only Na+ salts are soluble, Ca2+ salt gives thixotropic swollen particles; λ-C: all salts are soluble in cold water
Appearance of an aqueous solution Clear for pure extracts, opaque-turbid for PES
Viscosity of solution in water Medium to high (hot solutions set to gels when cooling)
Impact of heat on viscosity in water (pH 7) All κ-, ι-, and λ-C types are completely soluble in water and milk at T=80 °C (176 °F)
Viscosity development in water at pH 7 (T=0–100 °C) Complete solubility in water (or milk) at T= 80 °C (176 °F), viscosity is reduced by further heating (fully reversible at pH 7-9), solutions of κ- and ι-types set to gels upon cooling, gels are stable at room temperature, gels melt by heating and re-set upon cooling without loss of gel strength or texture in neutral conditions
Shear stability Solutions are pseudoplastic (reversible shear-thinning); κ-C-gels break when sheared (irreversible); ι-C-gels break by shear, but recover and re-gel after shear stress is removed
Thickening effect High
pH stability Medium (pH 5.5-9)
Decomposition κ-C + ι-C: hydrolysis by acid (accelerated by heat, low pH value, and time); however, gels are acid-stable; λ-C: hydrolysis in acidic systems
Film formation High
Emulsion stabilization High
Gelation κ-C: strongest gels with K+; ι-C: strongest gels with Ca2+; λ-C: no gelation with cations (but gelling with very high salt concentrations)
Gel strength and gel stability κ-C: firm brittle gels with strong syneresis, not freeze-thaw stable, hysteresis 10-20 °C (18-36 °F); ι-C: soft elastic texture, no syneresis, freeze-thaw stable; λ-C: no gels, solutions are freeze-thaw stable
Gel transparency High
Tendency for gel syneresis κ-C-gels: strong syneresis; ι-C-gels: no syneresis
Impact of electrolytes (cations +, 2+, 3+) κ-C: strong gelation with monovalent potassium ions; ι-C: strong gelation with divalent calcium ions; λ-C: no impact
Reaction with Ca2+ ions Gelation with ι-carrageenan
Protein activity κ-C. forms weak gels with κ-casein in milk to stabilize neutral dairy products and particles in suspensions; ι-C. and λ-C. have a strong protein interaction in acid
Crystallization control Gels of ι-C. and solutions of λ-C. are freeze-thaw stable, gels of κ-C. exhibit syneresis
Synergistic effects with other hydrocolloids κ-Carrageenan forms synergistic gels (increased gel strength and elasticity, reduced syneresis) with galactomannans (e.g. LBG) and konjac glucomannan; synergism between starch and ι-carrageenan
Other synergistic effects Solubility in 50% sugar solutions: κ-C. is hot-soluble, ι-C. is insoluble, λ-C. is soluble; solubility in 10% salt solutions: κ-C. is insoluble, ι-C. and λ-C. are hot-soluble
Negative interactions -
Dosage level in foods Low to medium (typical 0.02-3%)
