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.

Une composition de fibres de pectine réticulées par un cation polyvalent comprend une pectine à faible taux de méthoxyle, présentant une sensibilité au calcium et un degré d'estérification inférieur à 15 %, ou une pectine amidée sensible au calcium présentant un degré d'estérification inférieur à 50 %, cette pectine étant réticulable par un cation polyvalent et d'une masse moléculaire moyenne limitée à un maximum de 200 000 et à un minimum de 5 000. Cette pectine est utile pour préparer des pansements pour blessures destinés à des applications topiques.
