Technical Abstract: Increasingly consumers are becoming more sophisticated in their demand for diversity of products, greater health potential and good eating quality. The evaluation of a population of mandarin citrus (Citrus reticulata) and mandarin hybrids, was initiated in 2006-2007 with the goal of establishing baseline information on the components responsible for flavor and health. The database included sensory evaluation by a trained panel as well as chemical analyses of volatiles, sugars, acids, total phenolic compounds, and carotenoids. In addition, GC-olfactometry (GC-O) was applied to a select subset of samples, to determine which aromatic compounds, detectable by GC-MS, actually impact the perception of aroma. Data were analyzed using a variety of statistical approaches, and some relationships among individuals were inferred. A clear separation in quality was established among hybrids with sweet orange (C. sinensis) in their background, as opposed to those having more C. reticulata. Although there have been several reports on such work for sweet orange juice, there is little information currently available that addresses these factors in mandarin hybrids.
