Physical and Water Sorption Properties of Chemically Modified Pectin with an Environmentally Friendly Process

Abstract: A synthetic process was developed to modify pectin samples under solvent free conditions, obtaining pectin at increasing concentration of palmitic, oleic, and linoleic acids. The weight loss of the modified powders showed a degradation path very similar to the pure pectin, indicating that the pristine structure was preserved after the chemical modification. A decreasing mass of evaporating water on increasing the fatty acid concentration, in particular for the palmitic acid modification, indicated a reduced wa… Show more
