Refined Iota Carrageenan
Your Premier Refined Iota Carrageenan Supplier in China
Iota Carrageenan is extracted from the red seaweed 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%.

Applications
- Due to Refined 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, beverages, meat products, new health products, dietary supplements, pharmaceuticals, and daily chemical products (cosmetics), etc.
- It is usually used in water-based applications where a weak cohesive and elastic gel is required.
- It provides an elastic thixotropic milk gel especially well suited for cold-filled dairy products and for whipped applications.

Iota Carrageenan VS Gelatin
The use of iota carrageenan in dessert gel formulations affords gels that have textures very similar to those of gelatin gels.
They have an advantage over gelatin gels in that their melting point is higher so that they find a ready market in tropical climates or where refrigeration is not available. This is offset to some extent by the different mouth-feel since these gels do not "melt in the mouth", as does gelatin.
A further advantage is that iota gels retain their tender structure on aging, whereas gelatin tends to toughen.
This is important for ready-to-eat desserts, an item popular in Europe.

| 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 |
