                                Technical Abstract: Microwave assisted extraction (MAE) under pressure was used to acid extract pectin from lime flavedo, albedo and pulp.  Advantages of MAE over conventional heating methods in the extraction of pectin from citrus residues are 10 fold or better reduction in heating time, better control of extraction conditions and more narrow molar mass distributions.  Heating times ranged from 1 to 10 minutes.  Pectin dissolved in 0.05 M sodium nitrate was characterized by HPSEC with online static light scattering, dynamic light scattering and viscosity detection. Pulp gave the highest viscosity whereas albedo had the highest molar mass. Ratios of radius of gyration to hydrated radius were consistent with the concept that pectin behaves as a partially formed network structure in solution.
