Production of carrageenan from Malaysian seaweed

Two major red seawveed species available locally in Malaysia (in the coastal area of Sabah) wvhich are Kappaphycu5 alvarezii and Ellehewna dentieulatum where tested to the effect of alkali treatments on the yield and gel strength (quality) of the carrageenans which were collected from the different...

Based on the highest yield of carrageenan, Kappaphyclis alvarezii collected from Semporna been chosen for the next stage of optimization where this species been subjected to different condition of parameters which are KOH concentration (2.0-6.0%), temperature (65-95°C) and treatment time (l0-l20min).
