Carrageenan Production

An integrated method is developed to utilize to a maximum extent the fresh biomass of seaweeds such as Kappaphycus alvarezii that can be crushed to release sap and where the sap is useful as a potent liquid fertilizer after suitable treatment with additives and dilution while the residue is a superior raw material for extraction of κ-carrageenan, thereby enhancing the value of the seaweed. Other advantages of the invention include a reduced drying time and drying area to obtain the raw material for κ-carrageenan production in dry and storable form, a reduced cost of transporting and storing this raw material because of its lesser bulk, easier handling due to its free flowing granular nature, and its direct use for gel preparation in certain applications.Inventors: Karuppanan Eswaran, Pushpito Kumar Ghosh, Arup Kumar Siddhanta, Jinalal Shambhubhai Patolia,Chellaiah Periyasamy, Aditya Shantibhai Mehta, Kalpana Haresh Mody, Bharatkumar Kalidas Ramavat, Kamalesh Prasad, Mahesh Rameshchandra Rajyaguru, Singaram Kulandaivel Chennur Radhakrishna Reddy, Jayant Batukrai Pandya, Akhilesh Tewari
