Abstract

The unpleasant odour of noni (Morinda citrifolia L.) fruit has been a longstanding problem which is caused by octanoic acid. Deodorization of that compound have been performed using deacidification process. Deacidification of the octanoic acid using ion exchange resin was able to reduce the unpleasant odor but resulted in a reduction of beneficial antioxidant activities. Thus, this study was conducted to determine the effects of different types and weight of resin on the adsorption of octanoic acid and antioxidant compounds in noni juice during deacidification. Three types of weak base anion exchange resins (Amberlite IRA 67, Duolite A7 and Amberlite IRA 96) of different resin weight (0, 5, 10%, w/v) were used. The treated noni juice was analyzed for pH, antioxidant activity, total phenolic content (TPC), individual phenolic compounds and octanoic acid content. Deacidification of noni juice using the resins significantly (p Duolite A7> Amberlite IRA 96 for DPPH, FRAP, TPC and antioxidant compounds.
