![]() FDA regulationĬarrageenan as a food additive for direct addition to food for humans is regulated by FDA under 21CFR172.620. In icing or sauces, carrageenan gum is usually applied at low levels such as 0.25% or even lower. Carrageenan gums is usually added from 0.01-0.1% in bakery products. The addition of carrageenan gum will lower lightness color values of bread. In frozen dough, carrageenan gum helps to form gels. It helps: 3,4Ĭarrageenan gum helps to improve the specific volume of bread due to its interactions with glutens. ApplicationĬarrageenan gum is usually used for bread improvers for frozen dough. The viscous behavior of carrageenans can also help with slowing enzymatic diffusion and activity and reduced nutrient absorption. Refined carrageenan can be obtained using the same processing steps except for the use of alcohol instead of potassium chloride.Īs a dietary fiber, carrageenans are most beneficial for their role in viscosity-mediated gastrointestinal effects and their involvement in cholesterol reduction.Gel pressing, drying, milling and blending.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: Chemically, carrageenans are chains of repeating D-galactose and 3,6-anhydrogalactose units which can be sulfated or non-sulfated.
