Abstract

A method to deterpenate sweet orange and lemon oils by supercritical fluid extraction (SFE) with carbon dioxide combined with use of silica gel as adsorbent is described. The composition of the oxygenated fractions obtained by SFE was compared to that of deterpenated oils obtained by vacuum distillation, and to that of cold-pressed oils. The deterpenated products obtained by SFE show qualitative composition and quantitative ratios between oxygenated compounds near to those of original oils.
