Iotazoon (carrageenan), Biozoon, E 407

Iotazoon® is a type of carrageenan (E 407) derived from various species of red algae and is similar to agar-agar. Unlike agar-agar, however, the gel properties and strength of Iotazoon® are strongly influenced by the acidity and salt content of the formulation - adjustments may be necessary. In return, Iotazoon® offers interesting functional properties and often a better mouthfeel. It can be used as a gelling or thickening agent, for water binding and stabilization, e.g., in dairy products, for the production of pates, desserts, confectionery, as well as sauces and beverages. Iotazoon® gels in the presence of calcium (Calazoon®) and produces very flexible and soft gels, which, while not heat-stable, tolerate thawing and freezing very well. These gels possess thixotrophic properties, meaning that shaking, stirring, or chewing liquefies the gel, and it solidifies again after prolonged standing. This property gives the eater a melting mouthfeel and can also be used effectively when preparing foams. Even in its gelling state, the mixture can be portioned using a cream whipper because the gel liquefies again, and it still achieves the desired firmness after portioning.
