Open the CIPO recordAbstract From the Canadian patent
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.
