A study of the behavior of pectin substances in aqueous solutions by the light-scattering method

1. Pectin substances form high-molecular-weight aggregates in water.
2. When the temperature is raised, and also when sodium chloride, ammonium hydroxide, urea, and Tween are added, dissociation of the polysaccharide aggregates takes place (at given concentrations) — in a number of cases to particles with similar values of the weight-average and number-average molecular weights.
