The following steps are used in producing carrageenan gum: This unique property is dependent on temperature, concentration and ionic strength. Typically, it’s at 1.0 to 1.5% concentrations. One of the most beneficial properties of carrageenan gum, especially the kappa- form and its ability to form gels. The most common source is Gigartina from South America.

lambda: does not gel, and is used to thicken dairy products.

It is produced mainly from Eucheuma spinosum.

iota: forms soft gels in the presence of calcium ions.

It reacts with dairy proteins, and is mainly sourced from Eucheuma cottonii.

kappa: forms strong, rigid gels in the presence of potassium ions.

Typical characteristics of carrageenans are: The major source of carrageenan gum is red seaweed (also called Irish moss) or algae. Depending on the specific algae and method of extraction, three main classes of molecules are obtained: The more kappa carrageenan is added, the more brittle the final gel will be.Chemically, carrageenans are chains of repeating D-galactose and 3,6-anhydrogalactose units which can be sulfated or non-sulfated. If you want a more brittle gel you can replace some of the iota carrageenan with kappa carrageenan. For non-dairy gels, a 0.75% to 1.5% ratio is pretty standard. Iota carrageenan gels will usually use a ratio of 0.4% to 1.5% for dairy gels. It will melt about 5-10☌ / 9-18☏ above the setting temperature. The gel will set at 40-70☌ / 104-158☏, depending on the amount of calcium ions present. Heat the liquid above 70☌ / 158☏ then pour into molds and let cool. Make sure the liquid you are gelling is cold then use a standing or immersion blender to disperse the iota carrageenan into it. Making an iota carrageenan gel is similar to creating other gels. If the base ingredient lacks calcium it can be added in the form of calcium salts like calcium lactate or calcium chloride.

To gel, the liquid must contain calcium that is free to bind with the iota carrageenan. You can make the gel more brittle by adding kappa carrageenan. The firmness of the gel will depend on how much iota carrageenan is used.

How to Create an Iota Carrageenan GelĬreating a gel with iota carrageenan results in an elastic gel. For greater thickening you can make a fluid gel as described below. Anything much higher than that will begin to set as a gel. Usually, a ratio of 0.02% to 0.04% is used. The amount of iota carrageenan used to thicken liquids really depends on how thick you want the liquid to become. Then heat the liquid above 70☌ / 158☏ so it can hydrate. To thicken a dairy liquid first disperse the iota carrageenan into the cold liquid using an immersion or standing blender. Adding iota carrageenan to dairy based drinks or sauces is a great way to add thickness and improve mouthfeel. The simplest application of iota carrageenan is the thickening of dairy products. Iota carrageenan does not hydrate well with sugar and so sugar should be added after the hydration process is completed. In order for iota carrageenan to hydrate properly it has to be brought above 70☌ / 158☏.

An immersion blender or standing blender is the preferred tool to disperse the iota carrageenan. This will prevent hydration until the liquid is heated. Iota carrageenan is best dispersed in cool liquids. In order for iota carrageenan to be used effectively it has to be properly dispersed and hydrated. Iota Carrageenan Dispersion and Hydration

To thicken dairy liquids a ratio of 0.02% to 0.04% is often used. Iota carrageenan foams use 0.2% to 1.0% gels. Iota carrageenan fluid gels are typically made out of gels created with a 0.1% to 1.0% ratio. For dairy gels, 0.4% to 1.5% iota carrageenan is often used.

Usually a percent of 0.75% to 1.5% iota carrageenan is used for gels. The more iota carrageenan used, the firmer the gel will become. The firmness of an iota carrageenan gel is determined by the amount of iota carrageenan used to create it.
