Catalytic action of ion-exchange resin was tried for the deesterification of pectin prepared from apple pomace. Amberlite IR-120 and nalcite HCR of cation-exchange resin (H-form) showed 7.8% of deesterification at 85℃ (10 hrs) and 6.1% at 70℃ (10 hrs). respectively, while amberflite IRA-410 and nalcite SAR of anion-exchange resin (OH-form) did not catalyse the deesterification of pectin at 30℃ (10 hrs).It is concluded that the catalytic hydrolysis of ester of pectin is merely performed by ion-exchange resin, even if cation-exchange resin is strongly acidic sulphonated polystyrene of high exchange capacity. Application of ion-exchange resin will not probably afford promise of deesterification method in the practical production of low methoxyl pectin.
