The extraction and determination of physiochemical properties and yield of seaweed polysaccharide by different method was undertaken in the present study. Seaweed species Gracilaria edulis, Sargassum wightii (both wild collected) and Kappaphycus alvarezii (cultured) were collected from the Okha, Gujarat. Gracilaria edulis were used for extraction of agar with acid (0.5 N HCL) as well as alkaline (3% NaOH) methods. Kappaphycus alvarezii were used for carrageenan extraction using alkaline treatment (6% KOH). Carrageenan was separated by two different methods i.e. alcohol precipitation and freeze thawing. Alginate was extracted from Sargassum wightii with the help of calcium chloride (CaCl2) and formaldehyde treatments. In agar yield (25.08%) of alkaline treatment was high compared to acid treatment. The gel strength was higher in alkaline treatment (A2) (123.95 g). Alginate extracted by formaldehyde treatment (B2) showed highest yield (42.15%) and gel strength (806.94 g). Freeze thaw method for carrageenan showed higher yield (28.95%) and gel strength (995 g). Thus these promising finding may contribute to the on-going efforts for using seaweed polysaccharide as an alternative source for animal source or synthetic sources. [ABSTRACT FROM AUTHOR] |
