Notes:
A method is described for the recovery of volatile organic components of citrus juices by a continuous, reverse-phase, liquid-liquid extraction of the juice and distillation of the extract. The distillate may be used directly for gas chromatography. Six aldehydes have been identified. Recovery of added aldebyde exceeded 90%. Assay was by a eolorimetric 2,4-dinitropbenylhydrazone method. Total carbonyl content of concentrated orange juice rose sharply shortly after processing, followed by a slower decline. The changes were qualitatively similar whether a pure aldehyde or cold-pressed orange oil was added prior to frozen storage. Carbonyls in chilled orange juice followed a roughly similar pattern, with a final rise as microbial spoilage became apparent.
