C-TECH RKC is a traditionally refined, premium food grade carrageenan extracted from the red seaweed Eucheuma cottonii abundantly found in Indonesian waters. It underwent alkali treatment to enhance its gelling capabilities in both aqueous and milk systems. It forms thermoreversible gels at sufficient concentrations. It is highly sensitive to the presence of potassium ions that greatly enhance the gelation of the product.
