Title
(EN) REMOVAL OF BITTERNESS FROM CITRUS JUICES USING A POST-CROSSLINKED ADSORBENT RESIN
(FR) ELIMINATION DE L'ACIDITE DES JUS D'AGRUMES AU MOYEN D'UNE RESINE ADSORBANTE POST-RETICULEE
Abstract
(EN)
Bitter components, such as limonin, may be effectively removed from citrus juices, particularly navel orange juices, by contacting the juices with an adsorbent resin. The adsorbent resin is derived from a copolymer of a monoethylenically unsaturated monomer and a crosslinking monomer, where the copolymer has been post-crosslinked in the swollen state in the presence of a Friedel-Crafts catalyst and functionalized with hydrophilic groups. Preferably, the copolymers are styrene and divinylbenzene.
(FR)
On peut éliminer efficacement des constituants amers, comme la limonine, contenus dans les jus d'agrumes, en particulier dans les jus d'orange navel, en mettant en contact les jus avec une résine adsorbante. Cette résine adsorbante est obtenue à partir du copolymère d'un monomère non saturé de monoéthylène et d'un monomère de réticulation, où le copolymère a été post-réticulé à l'état gonflé en présence d'un catalyseur Friedel-Crafts et fonctionnalisé avec des groupes hydrophiles. Les copolymères sont de préférence du styrène et du divinylbenzène.
