Physicochemical Properties of Pectin from Retama raetam Obtained using Sequential Extraction

I. Kacem, H. Majdoub and S. Roudesli

Abstract:
Water-soluble polysaccharides were extracted sequentially from Retama raetam. Dried Alcohol-Insoluble Residues (AIR) of Retama raetam were treated sequentially with deionised water, ammonium oxalate and basic solutions and purified by ultrafiltration. The resulting pectin extracts analysed for some physicochemical parameters. The results show that pectin yield (62% dry AIR), uronic acid (260-640 mg g¯1), neutral sugars (320-540 mg g¯1), degree of methylation (20-31%) and acetylation (2-19%), molar mass (8. 93x104-3.42x105 g mol¯1) and intrinsic viscosity (27- 47 mL g¯1) varied with the various extraction methods used. Extraction with ammonium oxalate solution gave the highest pectin yield, with high molar mass and degree of methylation.
