Abstract
Deterpenation by concentration of the flavor bearing oxygenated compounds present in Citrus Essential Oils using the column chromatographic method and the parameters affecting the adsorption of these oxygenated compounds at maximum economy versus reasonable efficiency in separation from the non-oxygenated compounds have been studied. Particular attention was given to the maximum number of adsorption-desorption-regeneration cycles that a single column charge could be subjected to before the adsorbent should be replaced. The results of this study suggested the following conditions are of importance with regard to the development of an efficient and economic operation: 1) deactivation of the silica gel column by passage of a raffinate; 2) chilling of the column and feed oil to 5°C; 3) use of minimum silica gel/oil ratio; 4) in-place regeneration of the silica gel. The results of this study also demonstrates that no rearrangements of the non-oxygenated terpenes occurred.
