The formation of gel involves the association of randomly dispersed polymer segments in dispersion in such a way so as to form a three-dimensional network that contains solvent in the interstices. The associated regions known as junction zones' may be formed by two or more polymer chains. The gelation process is essentially the formation of these junction zones (Oakenfull 1987). Hydrocolloid gelation can involve a hierarchy of structures, the most common of which is the aggregation of primary inter-chain linkages into "junction zones which form the basis for the three dimensional network characteristic of a gel. The physical arrangement of these junction zones within the network can be affected by various parameters like temperature, presence of ions and inherent structure of hydrocolloid. For the gelation of hydrocolloids, the three main mechanisms proposed are ionotropic gelation, cold-set gelation and heat-set gelation (Burey et al. 2008)
