Optimization of Decolorization of Polysaccharides from Morinda officinalis How. Using D-900 Resin

doi:10.7506/spkx1002-6630-201208015

Abstract

Abstract: This study was undertaken to optimize the decolorization of polysaccharides from Morinda officinalis How. using D-900 anion exchange resin. Static and dynamic adsorption experiments were carried out to study the effects of temperature, resin dose, sample loading flow rate and pH on decolorization rate and polysaccharide retention rate. The optimal process parameters were dynamic adsorption at a sample loading flow rate of 1.0 BV/h, sample pH 6.0 and 45 ℃. In conclusion, higher decolorization rate and polysaccharide retention rate could be obtained by using D-900 anion exchange resin

Key words: Morinda officinalis How., polysaccharide, discoloration, anion exchange resin
