Carrageenan is semi refined food grade Kappa Karrageenan (E407a) 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. Carrageenan 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.
Semi-refined carrageenan is washed and alkali treated seaweed. The carrageenan is not extracted out of the seaweed but is still contained in the cell wall matrix. Commercial carrageenan products are frequently standardized for obtaining optimal gelling and thickening properties. By using the appropriate carrageenan product, the formulator can create textures ranging from free-flowing liquids to solid gels. In addition to offering standard types, COLORCOM works in conjunction with customers to develop new products and formulations for specific applications.
