Title (EN) CATALYST-FREE OZONE OXIDATION OF STARCH
(FR) OXYDATION D'AMIDON AU MOYEN D'OZONE ET SANS CATALYSEUR
Abstract: front page image
(EN)The invention relates to a method for the oxidation of starches or starch derivatives with ozone in an aqueous medium, wherein at least a part of the primary hydroxyl groups are selectively oxidized. In particular, root starches, such as tapioca starch, tuber starches, such as potato starch, and waxy cereal starches, such as waxy maize starch, are treated using the method according to the invention.
(FR)L'invention concerne un procédé d'oxydation d'amidons ou de dérivés d'amidon dans un milieu aqueux et au moyen d'ozone, ce procédé consistant à oxyder de façon sélective au moins une partie des groupes hydroxyles primaires. On traite, selon le procédé de l'invention, principalement des amidons de racines, tels que de l'amidon de tapioca, des amidons de tubercules, tels que l'amidon de pomme de terre, et des amidons de grains cireux, tels que l'amidon de maïs cireux.
