OPTIMATION STUDY OF CARRAGEENAN EXTRACTION FROM RED ALGAE (Eucheuma cottonii)
CarrageenanÂ isÂ aÂ generalÂ nameÂ forÂ polysacharides,Â itÂ isÂ madeÂ upÂ ofÂ sodium,Â potassium,Â magnesium,Â andÂ calciumÂ sulphatÂ estersÂ ofÂ galactoseÂ andÂ 3.6-anhydrogalactoseÂ units.Â ResearchÂ aboutÂ parametersÂ influencingÂ extractionÂ processÂ ofÂ carrageenanÂ fromÂ redÂ algaeÂ (EucheumaÂ cottonii)Â hasÂ beenÂ studied.Â TheÂ parametersÂ wereÂ particleÂ sizeÂ ofÂ redÂ algae,Â pHÂ ofÂ NaOHÂ solution,Â heatingÂ timeÂ andÂ heatingÂ temperature.Â AboutÂ 64.30%Â ofÂ carrageenanÂ wasÂ extractedÂ fromÂ redÂ algaeÂ (EucheumaÂ cottonii)Â underÂ optimumÂ condition,Â 425Â ÂµmÂ particleÂ sizeÂ ofÂ redÂ algae,Â solutionÂ pHÂ 8.5,Â heatingÂ timeÂ 18Â h,Â andÂ heatingÂ temperatureÂ 95Â°C.Â TheÂ FTIRÂ spectraÂ ofÂ extractedÂ carrageenanÂ showedÂ theÂ sameÂ spectraÂ asÂ theÂ pureÂ carrageenan.
KeywordsÂ :Â carrageenan,Â redÂ algaeÂ (EucheumaÂ cottonii),Â andÂ extractionÂÂ Â Â
