Recent development in surfactant technology has made it possible to produce surfactants based on plant extracts. A new material based on polyfructose extracted from roots of chicory was used as a stabiliser in 50% ZDBC dispersion and the properties were evaluated and compared with other systems. Although results of the light scattering technique did not show much difference in the particle size, a marked difference in the particle shape was observed when Transmission Electron Microscopy (TEM) was used. TEM micrographs of ammonium caseinate stabilised dispersion showed formation of uneven, saw like shaped particles with a wide particle size distribution whereas polyfructose stabilised dispersion showed formation of very even, circular shaped particles with a narrow particle size distribution. Viscosity results of polyfructose stabilised dispersion showed a pseudoplastic behavior similar to normal dispersion systems. Although a hard sediment formed with ammonium caseinate stabilised dispersion, no caking was observed in the polyfructose stabilised dispersion. back
