摘要

Individual CWCS pastes exhibit rheological behaviors ranging from liquid to solid-like depending on starch concentration. The presence of carrageenan in the continuous phase but without addition of KC1 does not lead to a significant enhancement of dynamic moduli over individual starch pastes. Addition of different concentrations of KC1 to starch-carrageenan mixtures leads presumably to the formation of three-dimensional networks having different degrees of rigidity as evidenced by the existence of a threshold salt concentration.
