- Abstract
Galactomannan gum extracted from fenugreek seeds was subjected to oxidation using sodium chlorite (NaClO2) under different NaClO2 concentration, pH, reaction time and liquor ratios. The products were analyzed for the acidic and reducing properties expressed as carboxyl and carbonyl contents, respectively. The rheological properties of the oxidized sample paste at a concentration of 3% were also measured. The suitability of the oxidized fenugreek gum either alone or in admixture with sodium alginate as thickeners in printing pastes was also studied.
