Binding Agents

All of the binding agents used in jellies are hydrocolloids. These are large molecules that disperse in water and, under the right conditions, bind together to form a gel consisting of a continuous three-dimensional network that traps water and particles. The binding agent in jellies performs two major functions: it increases the viscosity of the system to a point that allows it to be molded, cut, and otherwise handled; and it helps to prevent crystallization of the sugar in the jelly by locking sugar molecules in place, preventing aggregation and crystallization.
