Abstract
A polyvalent cation crosslinked pectin fiber composition is composed of a calcium sensitive low methoxyl pectin with a degree of esterification (DE) of less than 15% or calcium sensitive amidated pectin having a DE of less than 50% where the pectin is polyvalent cation crosslinkable and has an average molecular weight (MW) having an upper limit of 200,000 and a lower limit of 5000. This pectin is useful in making wound dressings for topical applications.
