Ambersweet orange hybrid: Compositional evidence for variety classification

The Ambersweet orange is a new orange hybrid that ripens in October and has good juice color. For the citrus-processing industry to be able to take full advantage of Ambersweet, its variety classification as an orange has to be established. Compositional analyses of volatile flavor and aroma constituents of Ambersweet fruit products were compared with those of similar products from the parent fruits, orange, tangerine, and grapefruit. All 21 constituents identified in Ambersweet fresh juice were identical with those in fresh orange juice with no appreciable quantitative differences. All 30 constituents identified in Ambersweet aqueous juice essence were identical with those in aqueous orange essence with no appreciable quantitative differences. Selected components of Ambersweet peel and essence oils important to flavor were found to be identical with those in orange peel and essence oils with no significant quantitative differences. Analogous compositional comparisons of these Ambersweet products with those of tangerine, Orlando tangelo, and grapefruit showed major qualitative and quantitative differences in all products analyzed
