Carboxymethylation of Tamarind kernel powder

Tamarind kernel powder is a rich source of xyloglucan gum. The gum can be utilized in a number of industries. With a view to utilize the gum for broader applications, carboxymethylation of tamarind kernel powder was carried out. The reaction conditions were optimized with respect to concentration of sodium hydroxide, monochloroacetic acid, solvent ratio, reaction time, and reaction temperature. Carboxymethylation of tamarind kernel powder increased its solubility in cold water and the stability of its paste to microorganisms. (C) 2006 Elsevier Ltd. All rights reserved.
