Notes:
Juices from four cultivars of sour orange (Citrus aurantium), Seville, Bigaradier, Sour and Bittersweet, were treated with neutral (XAD-16) and weak base anionic exchange (IRA-93) resins. Unidentified fluorescent compounds were removed along with bitter compounds by both resin treatments. Average acidity was reduced from 57–87% using IRA-93 before depletion. Average naringin concentrations were reduced 50–66% in high acid juice and 89% in low acid juice using IRA-93. Under similar conditions 24–30% of the limonin was eliminated using IRA-93 and essentially 100% removed using XAD-16. Sensory acceptance (9-point hedonic scale) improved from 1.6 to 3.0 after IRA-93 resin treatment of a high acid juice. Average acceptance increased from 3.8 to 6.4 after XAD-16 treatment of a low acid juice.
