  • Removal of bitterness from citrus juices using a post-crosslinked adsorbent resin
    Patent number: 4965083
    Abstract: 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.
