Removal of Bitterness by Using of Amberlite in Orange Juices

Abstract

-In this study, the removal of bitterness in Washington (navel) orange juice due to limonin was examined by using "Amberlite XAD-7HP" adsorbent. In the meanwhile, the changes on some chemical properties of orange juices such as (pH, titratable acidity, brix) were investigated. It had been determined that the adsorbent was successfully removed the bitterness in Washington navel orange juice. The results showed that bitterness caused from limonin was decreased from 90% to %96 at 30°C and 40°C, respectively. The bitterness of orange juice caused due to limonin was decreased up to %96 during using Amberlite XAD-7HP polymeric resin.
