The juices of provenance-specific, non-blended Valencia Late oranges were analytically investigated. Focus was put on the establishment of a correlation between sensory evaluation of these premium quality juices and their quantitatively recorded aroma patterns, which were elucidated by a specially designed purge and trap/thermal desorption/GC technique. While the astonishing, reproducible diversity of juices from different geographic origins was striking, sensory evaluation clearly showed that consumer acceptance is more correlated with the physicochemical properties of the specific juice matrices than with the content of single aroma constituents. The elucidation of the aroma pattern of non-blended provenance-specific juices contributes to a better understanding of oranges juices, clearly demonstrating that a specific amount of aroma or even single aroma compounds, often considered a necessity for reconstituted juices, is contradicted by the diversity of nature. |
