Abstract: | This study, the selective removal of limonin bitterness from Washington navel orange juice by batch adsorption to the Amberlite
XAD-16HP and Dowex Optipore L285 was investigated and the determination of some compositional changes that occurred with orange
juices debittering using adsorption resins were the primary focus. Amberlite XAD-16HP and Dowex Optipore L285 have been successfully
used to reduce bitterness to acceptable levels in Washington navel orange juices. Amberlite XAD-16HP does not have any important
negative effects on the quality characteristics of orange juices. However, Dowex Optipore L285 reduces the titratable acidity
(TA) in the orange juices and so increases the content of soluble solids contents (SSC), pH value, and ratio accordingly. |
