Pectin gel formation

WebAbstract. When calcium salts are added to an aqueous solution of polysaccharide pectin, ionic cross-links form between pectin chains, giving rise to a gel network in dilute solution. In this work, dynamic light scattering (DLS) is employed to study the microscopic dynamics of the fractal aggregates (flocs) that constitute the gels, while ... WebPectin needs partners, namely acid and sugar, to do the job of gelling properly. Acid helps extract pectin from fruit during gentle simmering and helps the gelling process, which will not take place unless the mixture is fairly acidic. If fruits (such as apricots) aren't sufficiently tart, a recipe will call for added lemon juice.
