Details
Carrageenan refined is extracted from Eucheuma Cottonii seaweeds. It forms thermoreversible gels at sufficient concentration and is highly sensitive to potassium ion which greatly enhances its gelling properties. Foodgel is stable in alkali medium.
Carrageenan is a naturally-occurring family of carbohydrates extracted from red seaweed.. Carrageenan is extracted with water under neutral or alkaline conditions at elevated temperature. Refined carrageenan is mainly recovered from solution by alcohol precipitation or potassium gelation.
Application
Carrageenan are large, highly flexible molecules that curl forming helical structures. This gives them the ability to form a variety of different gels at room temperature. They are widely used in the food and other industries as thickening and stabilizing agents. A particular advantage is that they are pseudoplastic—they thin under shear stress and recover their viscosity once the stress is removed. This means that they are easy to pump, but stiffen again afterward.
