AbstractThe main component of the taro corm is starch but appreciable quantities of water-soluble mucilage are also present. Taro mucilage was cold-water extracted and purified by dispersion and hydrolysis of starch, removal of starch hydrolysate and unconjugated protein. Compositional analysis of purified cold-water-soluble taro mucilage (PCWX) showed that galactose and arabinose were the main monosaccharides in the hydrolysate of PCWX and that the main polymer present was an arabinogalactan-protein. The yield of mucilage from 12 taro varieties varied from 75.7 to 137.0 g kg-1 (dry wt basis) amongst different varieties. The purity of the final mucilage arabinogalactan was confirmed by ion-exchange chromatography and electrophoresis.
