Abstract:

Carboxymethyl starch was prepared by dry method from cassava starch that was mechanically activated for 60 min using a stirring-type ball mill as the starting material, NaOH as the catalyst and ClCH2COOH as the etherification agent. The solubility, transparency, frozen-thaw stability, anti-aging capability, anti-biodegradation capability and apparent viscosity of prepared carboxymethyl starch were investigated. Results indicated that carboxymethyl starch products from activated cassava starch exhibited high solubility, better transparency, strong anti-biodegradation capability, high apparent viscosity, excellent frozen-thaw stability and anti-aging capability.

Key words: mechanical activation, carboxymethyl starch, paste property
