Abstract：Pectin is an acidic heteropolysaccharide found in plant cell walls and intercellular layers.Current research on its rheological properties mainly focuses on external factors,while the intrinsic mechanisms through which its own structural characteristics influence these properties remain unclear.In view of this,this paper focused on the molecular structure of pectin and systematically explained the relationship between its intrinsic structure,including source,extraction method,molecular weight,degree of substitution(methylation/acetylation),and side chain composition,and its rheological behaviors such as viscosity and gel strength.Furthermore,it explored how external factors such as temperature,pH,ionic environment,and processing methods could affect pectin's rheological properties by regulating its molecular structure,aiming to provide a theoretical basis for the application of pectin in the food industry.
