Iota Carrageenan

Your Premier Iota Carrageenan Manufacturer Supplier in China

Iota Carrageenan is a high-molecular-weight hydrophilic polysaccharide extracted from Eucheuma Spinosum. It is also known as calcium-sensitive carrageenan, which forms soft gels in the presence of calcium ions.

Iota Carrageenan is the only carrageenan style that is freeze/ thaw stable. Thus, a frozen Iota carrageenan gel will be completely syneresis-free when thawed. It is an excellent water binder in concentrations as low as 0.2%. 

As one carrageenan supplier in China, Gino Biotech offers a wide range of carrageenans including refined & semi-refined carrageenan from reliable iota carrageenan manufacturer and producer.

Applications

Due to Iota Carrageenan's  remarkable properties in gelling, thickening, emulsifying, film-forming and stably dispersing, it is commonly applied in various fields such as dairy products, meat products, dietary supplements and cosmetics, etc.

Features

E-No.E 407
OriginSeaweed extract
Chemical composition1. 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) – metabolism0 kJ (0 kcal); No resorption
Fibre content100% Soluble fibre
ToxicologyGlobal 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 solutionClear for pure extracts, opaque-turbid for PES
Viscosity of solution in waterMedium 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 stabilitySolutions 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 effectHigh
pH stabilityMedium (pH 5.5-9)
Decompositionκ-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 formationHigh
Emulsion stabilizationHigh
Gelationκ-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 stabilityκ-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 transparencyHigh
Tendency for gel syneresisκ-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+ ionsGelation with ι-carrageenan
Protein activityκ-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 controlGels of ι-C. and solutions of λ-C. are freeze-thaw stable, gels of κ-C. exhibit syneresis
Synergistic effects with other hydrocolloidsκ-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 effectsSolubility 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 foodsLow to medium (typical 0.02-3%)

Advantages
