Extraction and Physicochemical Properties of Refined Kappa-Carrageenan from Kappaphycus alvarezii Originated from Semporna, Sabah

In this research, the influence of different solvents (1.0 M KOH and 1.0 M NaOH) and different drying methods (freeze dryer and oven) towards the chemical and physical properties of refined carrageenan by using kappaphycus alvarezii collected from Semporna, Sabah were determined. The physical charac...

The physical characterizations involved were viscosity, surface morphology and functional group while, the chemical characterization was sulphate content. The result showed that the carrageenan yield were 12% (carrageenan extracted using 1.0 M KOH) and 18% (carrageenan extracted using 1.0 M NaOH) respectively for oven as a drying method. The carrageenan yield using freeze dryer was 10% (carrageenan extracted using 1.0 M KOH) and 12% (carrageenan extracted using 1.0 M NaOH). The functional groups identification for sulphate ester, anhydro-galactose and galactose were analyzed by using FT-IR.
