Interpretive Summary: An electronic nose is utilized to differentiate premium orange juices. Five not-from-concentrate and one from-concentrate juices were analyzed. Adequate separation was achieved between the samples with some overlap of two of the samples. This could indicate similar fruit sources or a processor providing the juice for two different labels. There were significant differences between replications and between air tanks. Multiple injections from the same sample vials produced a linear response.
