Pilot Scale Debittering of Kinnow Juice Using Adsorbent Amberlite XAD-16

Abstract

Use of adsorbent Amberlite XAD-16 packed in glass column was standardized to debitter the kinnow juice. The XAD-16 was regenerated after each lot by washing with 2.0 per cent sodium hydroxide solution. The reduction in limonin and naringin contents in the first lot (0-10L) was to an extent of 98.3 and 88.5 per cent, respectively, which decreased with its repeated use and the reduction of limonin and naringin in the eighth lot (70-80L) of serum was 68.2 and 17.7 per cent, respectively. The debittered serum was then reconstituted and the juice having 15 per cent pulp, 0.015 per cent orange essence blended to 16^oB TSS was prepared.
