| Abstract | Natural essential oils are used extensively in fragrances, flavorants, and in the food and pharmaceutical industries. During hydrodistillation, a part of the essential oil becomes dissolved in the condensate and lost as this water is discarded. In this study, carvone and limonene content recovered from hydrodistillation waste water of caraway fruit were quantified using two methods for recovering dissolved aromatic molecules from condensate water: extraction through distillation and extraction by means of a solvent. This allows for the conservation of useful molecules which are typically discarded with the waste water produced during the distillation process. The objective of this study was to quantify the carvone and limonene content recoverable from waste water derived from the distillation of caraway essential oil. The well-known Clevenger method and a simpler, more practical technique employing cyclohexane as a solvent were employed to determine the recoverable content of aromatic molecules from the hydrosol. The chemical compositions of the respective recovered extracts were compared with those of the primary oils to analyze the efficacy of these methods. Recovered extract accounted for 10 to 40 percent of the total oil yield. The limonene and carvone molecules recovered using these methods were quantified through gas chromatography in order to characterize the composition of the secondary extract produced. Los aceites esenciales naturales se utilizan ampliamente en las fragancias, saborizantes, y en la industria alimentaria y farmaceutica. Durante la hidrodestilacion, una parte del aceite esencial se disuelve en el condensado y se pierde como agua de descarga. En este estudio, el contenido de carvona y limoneno recuperados del agua de desecho de la hidrodestilacion de la fruta de alcaravea se cuantificaron utilizando dos metodos para recuperar las moleculas aromaticas disueltas en el agua condensada: extraccion a traves de la destilacion y la extraccion con un disolvente. Esto permite la conservacion de las moleculas utiles que normalmente son desechadas con las aguas residuales producidas durante el proceso de destilacion. El objetivo de este estudio fue cuantificar el contenido de carvona y limoneno recuperable de las aguas residuales procedente de la destilacion del aceite esencial de alcaravea. El conocido metodo de Clevenger y una tecnica sencilla y practica que emplea ciclohexano como disolvente fueron utilizadas para determinar el contenido de moleculas aromaticas contenidas en el hidrosol. La composicion quimica de los extractos recuperados fue comparada con los aceites primarios para analizar la eficacia de estos metodos. El extracto recuperado representa del 10 al 40 por ciento del contenido total de aceite esencial. Las moleculas de limoneno y carvona recuperadas mediante estos metodos se cuantificaron mediante cromatografia de gases con el fin de caracterizar la composicion del extracto secundario. |
