In the food industry, pectin is used
as a thickening agent in jams and jellies for texture formulation.
When water is added to pectin, it will give the
solution a viscous-like behavior. It can be dispersed in
sugar-concentrated syrups when the soluble solids concentration
is less than 30% with heating and smooth mixing
(Javanmard and Endan, 2010). In addition, acidity,
total soluble solid concentration, and calcium content all
influence pectin gelation (Mizrahi, 1979); increasing the
pH and ionic strength can decrease the viscosity of the
pectin solution.
