The Effect of Hydrodistillation Times and Cold Pressing on Yield and Composition of Sweet Orange (Citrus sinensis) Peel Essential Oil

Abstract

Within the scope of the study, the effect of hydro-distillation times on Citrus sinensis (Navelina) fresh peel essential oil composition was investigated. For this purpose, five different distillation times (10, 15, 30, 60, and 120 min.) were evaluated. Research findings showed that the distillation time was not effective on the orange essential oil composition. It was determined that the most important components of C.sinensis peel essential oil were limonene (96.52-96.61%) and myrcene (2.03-2.06%). In addition, hydrodistillation (HD) and cold press (CP) essential oils were compared in terms of yield and some physical and chemical properties. In terms of oil yield and optical activity, the values of the oil obtained by hydrodistillation method were higher than those obtained by cold press, and the refractive index and density values were found to be lower. In terms of component ratios, it was seen that there was no significant difference between the two methods.
