Abstract

Dispersions that comprise insoluble alginate/gelling ion particles in an alginate solution, wherein the dispersion exhibits less than 10% of final gel storage modulus after one minute in the absence of addition of non-gelling cations are disclosed. Kits and compositions for making such dispersions are disclosed and methods for making and using the dispersions, and the components used in the dispersions are also disclosed.
