Mirhosseini et al. (2008) found that the emulsion stabilizing
effect of pectin may be explained by the positive effect of pectin on
viscosity, pseudoplastic behavior and/or negatively charged
z-potential (repulsive forces). A hypothesis by Endreß and
Rentschler (1999) showed that high acetyl content in the
chemical structure of sugar beet pectin could enhance the hydrophobicity of pectin followed by increase in the cloud stability of
pectin-based emulsions. On the other hand, the presence of
hydroxyproline rich protein in pectin could also be responsible for
emulsion stabilizing effect induced by pectin
