Conformation of citrus pectin [uronide 93%, degree of esterification, 61.5%] solution was studied and experimental reduced storage [G']R and loss moduli [G"]R were compared with random coil theories of Rouse and Zimm and the rodlike theory of Marvin and McKinney. The theory of Zimm best approximated experimental data. This suggested that components of the pectin molecule internally interact to form a compact random coil with conformation controlled by hydrodynamic interactions.
